### Modernizing Healthcare Systems with AI and Machine Learning

Healthcare systems globally are under pressure to evolve. Aging populations, rising costs, and increasing demands for timely, personalized care are straining traditional infrastructures. Much of the challenge lies in outdated, siloed, and inefficient legacy IT systems that cannot keep pace with the speed and scale modern healthcare requires.



The gap between what’s possible and what’s practical has never been wider. While cutting-edge AI technologies promise to transform healthcare delivery, legacy systems built decades ago create barriers to innovation. Electronic health records that can’t communicate with modern applications, imaging platforms running on outdated protocols, and revenue cycle management systems vulnerable to security breaches all contribute to a healthcare landscape desperate for modernization.



Thus, Artificial Intelligence (AI) and Machine Learning (ML) are emerging as essential tools in driving the modernization of healthcare. These technologies offer transformative capabilities that can improve clinical decision-making, optimize hospital operations, and ensure scalable, data-driven care. This article explores how AI is reshaping healthcare across clinical, operational, and technical dimensions. Learn more about AI in healthcare system modernization.



Current Challenges in Legacy Healthcare Systems



Healthcare providers continue to struggle with outdated technology environments that were not designed for today’s data volume, interoperability demands, or real-time decision-making. Key challenges include:



Fragmented Data and Siloed Systems



Legacy systems often lack integration capabilities, making it difficult to access and share patient data across departments, facilities, or platforms. This fragmentation results in a lack of continuity in care, redundant testing, and communication errors. AI for electronic health records are the must nowadays.



Manual Processes and Inefficiencies



Administrative workflows such as appointment scheduling, billing, chart review, and claims processing remain heavily manual. These inefficient processes contribute to staff burnout, delays in care, and higher operational costs.



Lack of Real-Time Decision Support



Legacy systems typically cannot support the real-time data processing required for clinical decision support. This impedes a provider’s ability to deliver timely, data-driven care recommendations.



Scalability Issues



As population health demands rise, many systems struggle to scale their operations without significantly increasing staffing or infrastructure investments. Legacy platforms cannot accommodate modern AI-based automation or analytics without significant re-engineering.



Role of AI and ML in Modernizing Healthcare



AI transforms healthcare system modernization by enabling gradual enhancement rather than disruptive replacement. This approach preserves existing investments while adding intelligent capabilities that improve both operational efficiency and patient care quality.



AI serves as an intelligent bridge between legacy infrastructure and modern healthcare requirements. Rather than forcing healthcare organizations to abandon systems that still provide value, AI technologies can enhance existing platforms with advanced analytics, automated workflows, and predictive capabilities.



Enabling Seamless Data Interoperability



Natural language processing (NLP) revolutionizes how healthcare systems extract value from unstructured clinical notes. Medical professionals document patient encounters using varied terminology and formats, creating rich information repositories that legacy systems cannot analyze effectively.



AI for electronic health records are the must nowadays.



AI-powered NLP engines can analyze patient data across different formats, extracting relevant clinical information and making it searchable across systems. This capability transforms disconnected data silos into comprehensive patient records that support better clinical decision making.



Machine learning algorithms excel at normalizing patient data from multiple sources, creating unified views regardless of original system formats. When a patient transfers between facilities or sees multiple specialists, AI can aggregate their complete medical history into actionable insights for healthcare professionals.



These interoperability improvements enable real-time patient monitoring, comprehensive care coordination, and evidence-based treatment recommendations that improve health outcomes while reducing redundant testing and administrative overhead.



Automating Administrative Workflows



Healthcare organizations waste substantial resources on manual administrative processes that AI can automate effectively. Billing and claims processing, traditionally requiring significant human oversight, now benefit from AI systems that can code procedures, verify insurance eligibility, and identify potential claim issues before submission.



Predictive analytics optimize appointment scheduling by forecasting no-show probabilities, estimating procedure durations, and coordinating complex multi-provider visits. These capabilities reduce patient wait times while maximizing provider utilization and improving patient satisfaction.



AI-driven automation extends to prior authorization processes, medication reconciliation, and care plan coordination. By handling routine administrative tasks in clinical workflows, healthcare professionals can focus on direct patient care activities that require human expertise and empathy.



Revenue cycle management improves dramatically when ai tools identify coding errors, flag potential fraud, and optimize reimbursement strategies. Healthcare organizations report 10-30% improvements in collection rates and significant reductions in claim denials after implementing AI-powered revenue cycle systems.



Enhancing Clinical Decision Support



Clinical decision support tools powered by artificial intelligence analyze vast amounts of patient data to identify patterns that human clinicians might miss. These systems can predict patient deterioration, recommend personalized treatment protocols, and alert providers to potential adverse events before they occur.



Predictive models analyze historical data to identify high risk patients who would benefit from preventive interventions. Early identification of sepsis risk, fall probability, or readmission likelihood enables proactive care that improves patient outcomes while reducing costs.



AI-powered clinical decision support integrates seamlessly with existing electronic health record workflows, presenting relevant insights at the point of care without disrupting established procedures. Healthcare professionals receive actionable recommendations based on current evidence while maintaining final decision authority.



These systems continuously learn from patient outcomes, improving their accuracy and relevance over time. As healthcare organizations accumulate more data, AI algorithms become more sophisticated in their ability to support personalized medicine and precision care delivery.



Benefits of AI-Driven Healthcare Modernization



When modernize healthcare with AI, organizations get the following benefits:



Accelerated Diagnostics and Clinical Decisions



AI algorithms can process imaging data, lab results, and patient records faster and more accurately than manual review, leading to faster diagnosis and treatment. This reduces diagnostic error rates and shortens time-to-treatment windows in critical conditions such as stroke or sepsis.



Enhanced Patient Outcomes and Safety



Predictive models flag high-risk patients in real-time, allowing clinicians to intervene proactively. For instance, AI can identify early signs of patient deterioration, prevent avoidable readmissions, or support chronic disease management resulting in improved clinical outcomes.



Streamlined Operational Efficiency



Healthcare AI transformation removes bottlenecks in hospital workflows by automating routine tasks like claims processing, staff rostering, and discharge planning. This not only reduces labor costs but also minimizes delays and improves throughput.



Better Resource Allocation and Capacity Planning



AI-driven forecasting tools enable hospital administrators to predict surges in patient volumes, manage bed availability, and plan staffing more efficiently. This is critical for avoiding overcrowded ERs or understaffed departments.



Improved Population Health Management



By aggregating and analyzing patient data at scale, AI supports public health initiatives, such as identifying communities at risk for outbreaks, predicting disease progression, or optimizing vaccination campaigns. AI makes large-scale health data actionable and targeted.



Increased Clinician Satisfaction



Reducing the burden of administrative tasks frees up time for clinicians to focus on patient care. AI-assisted note-taking and summarization tools reduce documentation fatigue, contributing to higher job satisfaction and lower burnout.



Data-Driven Decision Making in Organizations



AI enables healthcare executives and policymakers to make informed decisions using real-time dashboards, insights, and forecasting tools. From procurement to quality control, data-backed strategies become more precise and impactful.



Challenges and Ethical Considerations of AI Implementation for Legacy Healthcare IT Systems



Implementing AI in healthcare offers tremendous promise, but it also introduces a unique set of challenges that require strategic planning, regulatory compliance, and ethical foresight. Below are some of the most pressing considerations:



Data Privacy and Security



AI systems must comply with strict data protection regulations like HIPAA in the U.S. and GDPR in Europe. These laws mandate robust security protocols for handling, storing, and transmitting sensitive patient information. Organizations must also implement access controls, encryption, and audit trails to maintain trust and regulatory compliance.



Algorithmic Transparency and Bias



Many AI models operate as "black boxes," making their decision-making processes opaque. This lack of transparency can erode trust and pose risks when algorithms exhibit bias across racial, gender, or socioeconomic lines. Ensuring algorithmic fairness requires diverse training data, continuous bias testing, and the use of interpretable models where possible.



Clinician Trust and Explainability



For AI to be adopted at scale, clinicians must trust its outputs. This is especially true in high-stakes environments like surgery or oncology. Explainable AI (XAI) techniques that provide clear rationale for recommendations—such as visualizations or supporting evidence—can help build confidence and foster adoption.



Cost and Procurement



Deploying AI solutions, particularly in environments with legacy infrastructure, involves substantial upfront costs, integration challenges, and training needs. In publicly funded systems like the NHS, procurement processes must comply with rigid standards that often slow innovation. A strategic roadmap that includes phased implementation and ROI modeling is essential.



NHS-Specific Challenges



In the UK, NHS system modernization efforts are complicated by systemic fragmentation and inconsistent levels of digital maturity across Trusts. Legacy systems vary widely in compatibility, and national infrastructure updates are often delayed. Additionally, Trusts must navigate multiple layers of governance and compliance frameworks before AI initiatives can be scaled.



Success Stories of AI-Powered Healthcare Modernization



Leading healthcare organizations have demonstrated that AI in healthcare system modernization delivers measurable improvements in both operational performance and patient care quality. These success stories provide blueprints for other healthcare systems considering similar transformations.



athenahealth and Abridge AI: Ambient Documentation Integration



In February 2025, athenahealth partnered with Abridge to embed AI-powered ambient clinical documentation directly into the athenaOne electronic health record platform. This integration represents a significant advancement in retrofitting legacy electronic medical records (EMR/EHR) systems with generative AI capabilities.



The ambient documentation system uses natural language processing to capture patient encounters through voice recognition, automatically generating structured clinical workflows that integrate seamlessly with existing workflows. Healthcare professionals report significant reductions in documentation time, allowing them to focus more attention on direct patient interactions.



Initial implementations show 40-60% reductions in time spent on clinical documentation, with corresponding improvements in physician satisfaction scores. The system maintains accuracy standards required for regulatory compliance while reducing the administrative burden that contributes to healthcare professional burnout.



AI and legacy EMR integration demonstrates how healthcare organizations can modernize core functionality without disrupting established workflows or requiring extensive staff retraining. By layering AI capabilities onto existing platforms, athenahealth provides a practical model for gradual system enhancement.



Mayo Clinic: AI-Enhanced Analytics in Legacy EHR Ecosystem



Mayo Clinic has successfully integrated AI-powered analytics modules into its existing electronic health record platforms, focusing specifically on predictive analytics for hospitals and patient outcome improvement. This approach allows the organization to maintain workflow familiarity while adding sophisticated analytical capabilities.



The implementation emphasizes readmission risk stratification, using machine learning algorithms to analyze patient data and identify individuals who would benefit from enhanced discharge planning or follow-up care. These insights appear directly within clinician dashboards, enabling proactive interventions without workflow disruption.



Clinical staff report improved confidence in discharge planning decisions and better coordination of post-acute care services. The system has contributed to measurable reductions in 30-day readmission rates while maintaining high patient satisfaction scores.



Mayo Clinic’s approach demonstrates how prestigious healthcare organizations can enhance their reputation for clinical excellence through strategic AI integration. The focus on evidence-based decision support reinforces the organization’s commitment to cutting-edge patient care.



National Institutes of Health: Complete EHR Modernization



The National Institutes of Health is executing a comprehensive modernization of its 20-year-old electronic health record system, embedding AI capabilities throughout both clinical and research operations. This ambitious project addresses the unique challenges of supporting complex research protocols while delivering clinical care.



The modernization strategy focuses on enabling more sophisticated research analytics, improving support for clinical trials, and enhancing data-driven care delivery. AI components include advanced patient matching algorithms, automated protocol compliance monitoring, and predictive models for research participant outcomes.



Expected improvements include better integration between clinical care and research activities, enhanced ability to identify eligible patients for clinical trials, and more granular analytics capabilities that support both patient care and scientific discovery.



The NIH project demonstrates how large-scale healthcare system modernisation can address both immediate operational needs and long-term strategic objectives. By embedding AI throughout the system architecture, NIH is positioning itself to lead healthcare innovation for decades to come.



Implementation Strategies for Healthcare System Modernization



Successful AI in healthcare system modernization requires careful planning, phased implementation, and comprehensive change management. Healthcare organizations must balance the urgency of modernisation needs with the complexity of maintaining operational continuity during transformation.



Phased Modernisation Approach



The most effective modernization strategy involves gradual enhancement of existing systems rather than disruptive replacement projects. This approach minimizes operational risk while allowing healthcare organizations to realize benefits quickly and adjust strategies based on experience.



Initial phases should focus on high-impact, low-risk applications such as automated documentation, basic predictive analytics, or enhanced data visualization. These implementations provide immediate value while building organizational confidence in AI technologies.



Subsequent phases can address more complex integration challenges such as advanced clinical decision support, comprehensive interoperability solutions, or sophisticated population health analytics. Each phase builds upon previous successes while expanding AI capabilities throughout the organization.



Change Management and Staff Training



Healthcare professional acceptance represents the most critical success factor in ai healthcare modernisation projects. Clinical staff must understand how AI tools enhance rather than replace their expertise, and they need confidence that these systems improve rather than complicate their workflows.



Early involvement in system design and pilot programs helps build stakeholder buy-in and ensures that AI implementations address real workflow challenges. Healthcare professionals who participate in selection and configuration processes become advocates for broader adoption.



Training programs should emphasize practical applications rather than technical details, focusing on how AI tools improve patient care and reduce administrative burden. Hands-on experience with pilot implementations builds confidence and identifies potential workflow improvements.



Ongoing communication about project progress, benefits realized, and lessons learned maintains momentum and addresses concerns proactively. Transparent discussion of both successes and challenges builds trust in the modernization process.



Compliance and Security Considerations



Healthcare system modernization must maintain strict adherence to HIPAA privacy requirements, data security standards, and clinical safety protocols. AI implementations require careful validation to ensure they enhance rather than compromise patient safety.



Risk assessments should evaluate both technical security measures and clinical safety implications of AI-powered systems. Strong encryption, role-based access controls, and comprehensive audit logging protect patient data throughout the modernisation process.



Vendor management processes must ensure that AI technology partners maintain appropriate security standards and comply with healthcare regulations. Regular security assessments and penetration testing validate ongoing protection of sensitive health data.



Clinical validation of AI algorithms ensures that automated decisions and recommendations meet established safety and efficacy standards. Healthcare organizations must document AI system performance and maintain human oversight of clinical applications.



Conclusion



The modernization of legacy healthcare IT systems is no longer a distant vision, but an urgent priority. AI and ML offer transformative potential across clinical, operational, and technical domains. By starting with strong data infrastructure and prioritizing practical use cases, healthcare organizations can improve outcomes, reduce inefficiencies, and deliver safer, more personalized care.

### How Generative AI Can Assist in Legacy Code Refactoring

Legacy codebases like the decade-old Java monolith, outdated enterprise-wide AngularJS solutions often sit at the heart of mission-critical systems, yet they are hard to understand, harder to test, and hardest to change. Stack Overflow’s 2024 survey found that 62 % of developers cite technical debt as their #1 frustration. IDC reports that almost half of enterprises overspend on digital infrastructure because of legacy upkeep, while a SnapLogic study pegs annual maintenance costs at US $2.9 million per company. Refactoring is the cure, but large-scale rewrites are famously expensive, risky, and time-consuming.



While generative AI comes to simplify and automate a lot of processes, legacy code refactoring is also not an exception. Leveraging large language models (LLMs) such as GPT-4, Claude, or Gemini, development teams can summarize 10-year-old functions, detect code smells, scaffold tests, and even convert whole frameworks in minutes. McKinsey estimates that generative AI can shave 20–30 % off refactoring time and up to 45 % off net new code writing. 



This article explains why legacy refactoring is tough, where AI-assisted code refactoring shines, and how to use these tools safely.



Why Refactoring Legacy Code Is Challenging



Many companies postpone refactoring their systems until something critical breaks. Why? Because refactoring is lengthy, costly, and resource-intensive. Let’s break down the key challenges:



High Coupling, Low Cohesion



Years of “just-ship-it” hot-fixes glue unrelated modules together until the code resembles a plate of spaghetti. Classes reach across layers to grab data, duplicate utilities creep in, and circular dependencies appear. Change a seemingly innocent helper method and half the application recompiles or worse, compiles but fails in production. That's why developers learn to “touch nothing that works,” freezing innovation.



Missing Test Suites and Weak Version Control 



Many legacy repos pre-date today’s testing culture; unit tests were “nice to have” and integration tests non-existent. Without a safety net, any refactor becomes a game of whack-a-bug, requiring slow manual QA. Compounding the risk, early CVS or Subversion histories may have been lost during tool migrations, erasing commit context and making it hard to trace why code behaves the way it does.



Obsolete Frameworks and Syntax 



Enterprise stacks still running VB6, Java 6 or .NET Framework 3.5 can’t use modern libraries, IDEs, or container orchestration. Build pipelines require antique compilers or 32-bit DLLs that won’t run on current operating systems. Even compiling the code locally is an ordeal, let alone refactoring it to adopt dependency injection or micro-ORMs.



Opaque Business Logic 



Critical domain rules such as pricing tiers, tax calculations, compliance checks often sit in 3 000-line methods written by engineers who left years ago (at best). Variables bear cryptic names like flagX or tmp2, comments have rotted, and the only “documentation” lives in tribal knowledge. Untangling that logic is a prerequisite to safe refactoring, yet it can take weeks of code archeology.



Hidden Side Effects



Global state, mutable singletons, scheduled batch jobs, and direct database hits make behaviour unpredictable. Functions that look pure actually update static maps; nightly jobs rewrite data behind the scenes. Such side effects mean an innocuous refactor, like extracting a utility class can alter execution order or state, triggering bugs that surface only under production traffic patterns.









These factors create a technical-debt snowball: new features take longer, defects slip through, and each delay increases pressure to modernize yet makes the leap riskier.



What Is Generative AI and How Does It Apply to Refactoring?



Generative AI is a family of large language models (LLMs) built on the transformer architecture. Trained on billions of code lines and natural-language tokens, an LLM predicts the next token in a sequence, enabling it to draft functions, translate comments.



Because the model “learns” statistical correlations across many languages, frameworks, and idioms, it can both understand legacy constructs and propose modern equivalents; something rule-based static-analysis tools cannot do. IBM notes that this semantic breadth helps “de-risk modernization programs” by exposing hidden dependencies before a single line is changed.



Why use generative AI for legacy code?




Speed & cost – GitHub reports that Copilot now produces up to 46 % of code in active repositories and can make developers 55 % faster on routine tasks. When those tasks include renaming variables, inserting null-checks, or porting 1990-era APIs, the savings translate directly into shorter refactor cycles.



Contextual reasoning – Unlike linters that flag a pattern in isolation, an LLM reads filenames, neighbouring functions, commit messages, and docstrings, so its suggestions align with domain vocabulary and architectural conventions.



Legacy visibility – Generative AI surfaces “hidden business rules” embedded in legacy code, accelerating discovery phases that once consumed 30% of modernization budgets.



Continuous guidance – As you touch one module, the model can preview ripple effects across the monolith, highlight missing tests, or draft migration snippets acting as an always-on AI-assisted programming partner.




How generative AI works on legacy codebases




Tokenize & embed – The source file (old VB6, COBOL copybook, or AngularJS) is split into sub-token pieces and embedded in high-dimensional vectors capturing syntax and semantics.



Attend over long context – Modern LLMs hold hundreds of thousands of tokens, so they can load entire repositories and reason about cross-file patterns (e.g., duplicated SQL).



Predict & critique – Given a prompt like “Convert this .NET Core/Framework function to .NET and add type hints,” the model generates a draft; reinforcement-learning or retrieval-augmented steps then refine answers against best-practice corpora.



Human loop – Developers review diffs, run tests, and give feedback, which the model uses in the next prompt-response cycle.




Tools such as GPT-4, GitHub Copilot (Codex), Amazon CodeWhisperer, Claude, or Sourcegraph Cody can therefore complete code, answer API questions, or draft pull-request text.



GPT-4 / Codex (OpenAI). OpenAI’s GPT-4 exposed to developers through the Codex family of models, remains the most general-purpose option, powering GitHub Copilot, ChatGPT Enterprise, and a growing ecosystem of CLI, CI/CD and IDE plug-ins. Beyond autocompletion, GPT-4 can refactor code while preserving behavioural correctness across multiple benchmarks and even generate explanatory documentation for its changes, confirming its usefulness in large-scale clean-ups. 



Because Copilot hooks directly into pull-request workflows, linting pipelines and chat UIs, teams can weave AI-assisted code refactoring into everyday reviews instead of treating it as a one-off migration step.



Claude 3 (Anthropic). Marketed in developer circles as “Claude Code,” Anthropic’s latest model ingests entire repositories thanks to a huge context window — 200K tokens in current benchmarks, which lets it reason over cross-file patterns, spot duplicated business logic and propose transformative refactors.



Running from the terminal alongside any IDE, Claude emphasises safety: Anthropic’s Constitutional-AI guardrails reduce hallucinated APIs and risky rewrites, a critical feature when modernizing regulated legacy stacks.



Gemini 2.5 (Google). Gemini powers Gemini Code Assist, now integrated into VS Code, Cloud Shell, and Vertex AI pipelines. Within those environments, developers can ask the model to transform legacy syntax, map on-prem APIs to managed Google Cloud services, or apply refactoring patterns across whole folders, features backed by a context window that scales to one million tokens in preview builds.



Because Code Assist is wired into Google Cloud’s CI/CD and security tooling, it guides “build-deploy-operate” loops end-to-end, making it especially attractive for cloud-migration and code transformation using AI scenarios.



While each model differs in context size, fine-tuning controls, and pricing, all three deliver the core promise: machine learning code transformation that speeds the journey from brittle monolith to maintainable, test-covered modules. The choice hinges on your compliance needs, preferred IDE, and whether your roadmap leans toward Microsoft, Anthropic, or Google ecosystems.



Key Ways Generative AI Supports Legacy Refactoring



When you know where and how to apply GenAI to legacy code refactoring, it can deliver tremendous value to any organization. So let’s explore the processes GenAI can support or even take over:



Comment and Documentation Generation



LLMs can read an un-documented 500-line function and output concise summaries, docstrings, and usage guides. This speeds on-boarding and forms the narrative you’ll need when decomposing a legacy monolith.



Identifying Code Smells and Anti-Patterns



Prompt the model with “List the code smells in this file” and it flags long parameter lists, deep nesting, duplicated logic, and unhandled exceptions, then maps each to classic refactoring moves such as Extract Method or Introduce Strategy. That blend of code smell detection and prescriptive advice was once available only in costly tooling; now it lives in your IDE.



Generating Unit Tests for Untested Code



By analysing control flow and function signatures, generative AI can scaffold unit test generation that covers edge cases developers might miss, enabling test-driven rewrites without halting feature delivery.



Assisting with API and Dependency Modernisation



Ask, “Replace this deprecated .NET Framework WebRequest API with HttpClient/IHttpClientFactory in .NET 8,” and the model outputs transformed snippets plus rationale—much like prompts that swap obsolete logging libraries or migrate your data layer to Entity Framework Core, all key moves in legacy system modernisation with AI.



Converting Old Languages or Frameworks



GenAI can lift VB6 or classic ASP code into modern C# and .NET 8; translate Python 2 syntax to Python 3 while adding type hints; convert monolithic Java or Spring MVC projects to lighter Spring Boot micro-services; swap AngularJS components for Angular 18 or 20 equivalents; replace old WinForms UIs with WPF or Blazor; and even suggest COBOL-to-Java or PL/SQL-to-Kotlin transformations for mainframe off-loads. 



In each case, the model drafts the new code, flags manual edge cases, and inserts TODOs where human review is essential while turning months of rote rewriting into a guided, iterative clean-up.



Code Review and Quality Suggestions



Generative models summarize pull-request diffs, highlight risky areas, and even propose GPT code refactoring suggestions inline, freeing senior engineers for architectural oversight rather than nit-picking style.



Tools That Use Generative AI for Refactoring



GitHub Copilot (OpenAI / Microsoft)Copilot’s Codex- and GPT-4-powered suggestions now write up to 46 % of the code in sampled repositories and measurably shorten task-completion time for everyday engineering work.





Pros: deeply embedded in VS Code, JetBrains, and the GitHub web UI; generates whole-file refactors, pull-request summaries, and inline docstrings; enterprise plan offers private-model hosting and policy controls.





Cons: large contexts (>300 KB) can still hit token limits; privacy features require the paid tier; models occasionally hallucinate APIs, so every diff needs human review.





Amazon CodeWhispererBuilt into Cloud9, VS Code, JetBrains IDEs, and the AWS CLI, CodeWhisperer adds one-click “AI-powered code remediation,” security scanning, and infrastructure-as-code (IaC) transformations that align with AWS best practices.





Pros: tight IAM integration, automatic reference-tracking to flag licence conflicts, and free unlimited usage for individual developers.





Cons: strongest on Java, Python, and TypeScript; suggestions skew toward AWS SDKs—less useful if you’re migrating away from AWS or working in niche languages.





OpenAI GPT-4 / CodexOpenAI’s general-purpose LLM excels at cross-language rewriting and complex refactors; internal studies and recent launches show it can autonomously rewrite code, fix tests, and preserve behaviour across benchmarks.



Pros: best-in-class reasoning, huge plug-in ecosystem, accessible through ChatGPT Code Interpreter, REST API, and GitHub Copilot.Cons: high cost at larger context windows; latency spikes on very long prompts; enterprise users must proxy through Azure OpenAI for strict data residency.



Refact.ai (open-source)Refact’s self-hostable agent delivers autonomous patch generation, multi-file reasoning, and has reached 70 % pass@1 on SWE-bench—the top open-source score to date.





Pros: on-prem deployment, retrieval-augmented context, and an approval queue that lets teams gate every patch before merge.





Cons: smaller model zoo than commercial rivals; setup demands GPU nodes and DevOps effort; community support still maturing.





Sourcegraph CodyCody indexes your entire repository graph so chat replies can span packages and symbol references, enabling true AI pair programming on monorepos. Updates in 2024 added larger context windows and Claude-3 integration.





Pros: first-class support for multi-repo workspaces, self-hosted Sourcegraph instances for privacy, and fine-grained @-mention context injection.





Cons: initial setup is heavier than a browser plug-in; context window currently capped (≈7 k tokens) to maintain precision, with larger limits still in beta.





JetBrains AI AssistantBundled with IntelliJ IDEA, Rider, PyCharm, and the 2025.1 IDE releases, JetBrains’ assistant taps the project model for deep context awareness and can rewrite code, create tests, or explain complicated build scripts.



Pros: understands Gradle, Maven, and IntelliJ inspections; no extra plug-in required for subscribers; respects per-file scopes when proposing edits.Cons: locked to JetBrains IDEs; enterprise on-prem model routing is still preview-only; smaller training set than Copilot, so coverage of obscure stacks may lag.



7 Best Practices for AI-Assisted Refactoring



1. Keep humans firmly in the loop



Treat every AI-generated change as a draft, not a final answer. Walk through the diff line by line, run the code locally, and confirm that the behaviour still matches user expectations. Use pull-request reviews, pair-programming sessions, or “rubber-duck” walkthroughs to validate intent as well as syntax. This human verification step catches hallucinated APIs, subtle logic mismatches, and style violations before they reach production.



2. Defend with tests and static analysis



Automated refactoring is only safe when backed by solid safety nets. Maintain a fast unit-test suite that exercises critical paths, supplemented by integration tests for cross-module contracts. Add static analysis (linters, type checkers, security scanners) to every commit so that regressions are flagged the moment the AI inserts them. Run all of these gates in continuous-integration pipelines to detect issues long before deployment.



3. Commit incrementally



Ask the model to tackle one concern at a time: rename a method, swap a library, or extract an interface, and then commit the change in isolation. Small, focused commits make reviews quicker, simplify conflict resolution, and let you revert a single patch without undoing other progress. Incremental work also provides a breadcrumb trail of intent that future developers (and future AI prompts) can follow.



4. Version-control everything



Create a dedicated branch or tag a restore point before launching a wide AI sweep. This clean baseline lets you cherry-pick successful patches while discarding misfires. Use descriptive branch names and commit messages that capture the goal of each AI run so history remains understandable months later.



5. Prompt with clear constraints



Generative models respond best to explicit boundaries. Include language standards (“C# 10, nullable enabled”), performance budgets (“avoid allocations in hot loops”), security rules (“only parameterised SQL”), or architectural patterns (“repository pattern, no direct DAL calls”). Clear instructions reduce off-spec suggestions and shorten review cycles because the AI is aiming at a well-defined target from the start.



6. Log prompt/response pairs for traceability



Store each prompt and the model’s reply either in the commit message, an attached markdown file, or an internal log. These records make it easy to reproduce a change, explain decisions to auditors, and retrain or fine-tune future models. In regulated environments, prompt logs also prove that sensitive code never left approved boundaries and that every automated edit passed through a documented approval process.



7. Know when to call in professional help



If your refactor touches mission-critical code, highly regulated domains, or legacy platforms with sparse documentation, engage an experienced software modernisation specialist. A legacy software modernization company with an AI background can validate your AI workflow, design test harnesses, and set guardrails that prevent costly missteps; all for turning AI assistance into a reliable accelerator rather than a risky experiment.



When Not to Use AI for Refactoring



Generative AI is powerful, but think twice to apply it when:



Mission-critical systems with little or no test coverage



If the application controls aircraft routing, medical-device telemetry, real-time trading, or any workload where a single regression could endanger lives or cause massive financial loss, AI-driven refactoring is risky. Without a comprehensive test suite (unit, integration, and end-to-end), you have no automated proof that an LLM’s edits preserve behaviour. 



In these contexts, focus first on building a safety net like characterisation tests, contract tests, sanity monitors, before letting an AI suggest changes. Until those guardrails exist, limit AI use to non-production sandboxes or documentation tasks.



Codebases in highly regulated domains



Industries such as healthcare, defence, and payments often restrict how and where source code may be processed. Even if you run models on-prem, LLMs can hallucinate APIs, reorder logic, or omit mandatory audit hooks, putting you out of compliance with standards like HIPAA, IEC 62304, or PCI DSS. 



For code that must satisfy strict certification, confine AI assistance to low-risk activities like drafting migration guides, or highlighting potential code smells, while keeping all behavioural changes under traditional, tightly controlled review cycles.



Side-effect-heavy monoliths with undocumented behaviour



Many legacy applications rely on global state, batch jobs, and implicit data contracts. Because these side effects aren’t obvious in the code’s surface syntax, an LLM can easily move or rename a function that silently updates shared memory, breaks a nightly batch process, or violates a fragile ordering dependency. 



Before unleashing AI on such a codebase, isolate seams manually: wrap shared state in explicit interfaces, add logging to hidden workflows, and write “characterization” tests that capture current behaviour. Only then should you apply AI-generated refactors; incrementally, behind feature toggles, and with rollback plans.



Systems already slated for rewrite or replacement



If the organization has approved a green-field rebuild or a migration to SaaS, large-scale AI refactoring can become wasted effort. 



Instead, channel AI assistance into code understanding: documentation generation, domain-rule extraction, dependency mapping, so the new architecture inherits clean specs without inheriting technical debt.



Code reliant on proprietary or obscure DSLs



LLMs are strongest on widely used languages and frameworks. For in-house DSLs or rarely encountered 4GLs, model suggestions can be wildly inaccurate. 



In those cases, lean on domain experts and custom static-analysis tools, reserving AI usage for commentary or high-level redesign discussion rather than direct refactors.



When organisational change management is the real blocker



Sometimes velocity issues stem not from code quality but from release processes, approvals, or siloed ownership. 



Dropping AI into that environment risks accelerating the technical side while leaving cultural bottlenecks intact. Address organisational constraints first; then use AI to reinforce new, disciplined workflows.



Conclusion



Generative AI doesn’t wave a magic wand over legacy sludge, but it does compress discovery, documentation, and transformation cycles that once took months into days. By pairing AI-assisted code refactoring with solid engineering discipline: tests first, reviews always, organizations can refactor legacy code with AI safely, reduce technical debt, and carve a path toward future-proof architectures.



Getting started is easier than you might think: begin on a low-risk module, prompt an LLM to map dependencies and suggest refactors, then run the new code through your test-suite and code-review gates. Each successful increment builds confidence, accelerates velocity, and frees budget for higher-value innovation.

### RPA for Legacy Systems: Opportunities and Limitations

It’s clear that legacy systems have become a major setback for most organizations. With the advent of AI, these systems now have a second chance to be upgraded. Let’s take a closer look at how automation can help.



Robotic Process Automation (RPA) is best known for its ability to replicate human interactions with software. That deceptively simple skill set makes RPA uniquely valuable where modern integration paths are scarce: legacy systems still running core business processes. Decades-old mainframes, green-screen ERP modules and bespoke terminal apps often hold critical data but expose no APIs, slowing digital-transformation efforts. 



By laying a non-invasive “automation layer” over the existing user interface, RPA lets organizations automate legacy applications without touching a line of source code, buying precious time while larger migration or re-platforming projects get funded and built.



The Opportunity: Why RPA Works Well with Legacy Systems



The global RPA market, already worth 28.31 billion in 2025 and growing at 17 % CAGR, has become the fastest, safest way to bolt modern automation onto COBOL, green-screen and terminal environments. In short, RPA for legacy systems is less a fad than a pragmatic response to the twin pressures of cost containment and continuous modernization.



So, what are opportunities for legacy systems 



1. No Need for APIs or Code Access



RPA bots drive the UI exactly as a person would – keystrokes, mouse clicks, hot-keys or 3270 terminal commands. UiPath’s Terminal Session activity, for example, emulates TN3270/TN5250 sessions directly on the robot; no third-party emulator is required. 




Ideal for green-screen applications where screen-scraping is the only option.



Enables API-less integration for packaged apps whose vendors no longer exist.




2. Fast Implementation



Because no back-end refactoring is needed, an RPA proof-of-concept can go live in weeks, delivering measurable value long before a full system-replacement budget is approved. Organizations now favor “hybrid modernization,” combining mainframe robustness with quick automation overlays to capture early savings.



3. Business Continuity Support



Bots can run 24/7, copy-pasting data between systems, validating entries and triggering emails – all without disrupting users still working in the legacy UI. Companies using RPA for data reconciliation and audit reporting report lower manual error rates and smoother regulatory cycles.



4. Extends the Life of Legacy Investments



Instead of a risky “big-bang” cut-over, RPA lets IT wrap legacy apps with workflow automation, process orchestration and reporting dashboards, squeezing extra ROI out of sunk CapEx. Analysts note that every year of service extension can delay multi-million-dollar migrations.



RPA for Legacy Systems: Common Use Cases 



Let's consider different uses cases of RPA for leagcy systems. 



Automating repetitive back-office workflows 



Think of the thousands of keystrokes a finance clerk performs every day: copying invoice data from email attachments into a green-screen accounting package, reconciling purchase orders, or ticking off payments in a 3270 mainframe. RPA excels here because it mimics those exact UI interactions, applying the same business rules the human would—but at machine speed and around the clock. By screen-scraping legacy systems and injecting data directly through the presentation layer, bots slash manual effort, boost accuracy, and free staff for exception handling instead of swivel-chair data entry.



Bridging legacy ERP with cloud platforms 



In many organisations, critical records still live in on-premise SAP ECC, Oracle E-Business Suite, or custom COBOL ERP modules that expose no modern APIs. RPA bots provide an “API-less integration” bridge, logging into the legacy UI to pull order status or inventory levels, then pushing the data into SaaS analytics tools, CRM systems, or serverless functions in the cloud. The result is near-real-time information flow without waiting for a costly middleware project—an especially powerful tactic during phased ERP modernization.



Data migration between disconnected systems 



Whether you’re consolidating acquired subsidiaries or sunset-ting an ageing database, bulk data movement is painful when schemas don’t align and native export utilities are missing. RPA can orchestrate the migration by reading records from one system-of-record, transforming them on the fly (e.g., reformatting dates, normalising customer IDs), and loading them into the target application through its own UI or import wizard. Because the bot operates exactly as an end user would, you avoid risky direct database writes while still achieving high throughput.



Regulatory and audit reporting automation 



Compliance teams often spend late nights gathering figures from legacy ledgers, HR systems, and industry-specific registries to meet SOX, Basel III, HIPAA, or GDPR mandates. RPA streamlines the process by running unattended at predefined cut-off times, extracting data points, cross-checking totals, and assembling reports or evidence packs. Each step is logged for traceability, reducing audit friction and demonstrating robust governance—even when the underlying source applications are decades old.



Key Limitations of Using RPA with Legacy Systems



Despite for a lot of benefits and opportunities RPA presents for legacy solutions, there're some limitations for implementation.



1. Fragile & UI-Dependent



Robots rely on selectors (HTML IDs, XPaths, window handles, TN3270 coordinates, etc.) or on pixel/OCR matching to locate elements. Any change in:




DOM attributes (dynamic IDs, CSS classes);



Screen resolution / DPI scaling on virtual desktops;



Green-screen field offsets after a vendor patch;



Unexpected modal pop-ups or toast banners.




can cause the bot to throw an exception. Even "moving a field two pixels" breaks the selector and triggers re-work. Vendors now ship self-healing add-ons (e.g., UiPath Healing Agent) that re-calculate selectors at run time, but they still require rule tuning and do not fully solve the regression-testing burden. 



Extra technical considerations




Frame/iframe nesting and shadow-DOM elements raise detection latency.



Bots that scrape via OCR lose accuracy with font or colour changes.



Citrix/RDP sessions add a second layer of image compression, making pixel offsets less reliable.



Every desktop build (Citrix Golden Image) must be frozen for the bot version it hosts.




2. Not a Substitute for Modern Integration



RPA pushes and pulls data through the presentation layer, outside the transaction boundary of the underlying system. Consequently:




No ACID guarantees. Two bots updating the same record can create race conditions as there is no database-level lock or rollback.



No schema-level validation. Field-length or data-type violations surface only when the UI rejects the entry.



Poor event visibility. Downstream systems see only the after-state; they can’t subscribe to fine-grained change events as they would with an API or message bus.



Hidden business logic. Rules hard-coded in scripts become a new “black box,” increasing overall integration debt.




Architects therefore treat bots as edge shims until proper service wrappers, ESB connectors, or iPaaS flows are available. Over-reliance can produce the “automation spaghetti” called out by industry critics. 



3. Scalability Constraints



Every unattended bot typically maps 1-to-1 with a Windows or Linux VM/desktop. Scaling volume from 10 → 1 000 transactions per hour thus means scaling bot runners, virtual desktops, licensing and orchestration capacity.



Technical pressure points




Orchestrator throughput. Queue polling and log ingestion can become IO-bound; some controllers cap at ~10 000 job starts/hour.



Licence concurrency. Vendors sell “runtime” or “digital worker” licences—each extra parallel bot increases OPEX.



VM sprawl & patching. Hundreds of images require OS & antivirus updates, driving infra overhead.



Load balancing. Without native autoscaling, admins script manual distribution or adopt hosted RPA services (e.g., Power Automate Hosted Machine Groups) that still incur cloud VM costs.




Analyst reports flag scalability as a top blocker to enterprise-wide roll-outs when compared to API-first microservices.



4. Security & Compliance Risks



Bots possess human-equivalent entitlements yet run 24 × 7, thus making them attractive targets.



Key technical factors:




Credential vaulting. Secrets stored in local config files or plaintext orchestrator variables violate zero-trust policies. Use enterprise vaults (CyberArk, HashiCorp) with short-lived tokens.



Non-repudiation. Consolidate logs from runners, orchestrators and target apps into a SIEM; include data-access context (record IDs, before/after values) for forensics.



Segregation of duties (SoD). A bot that extracts payroll data and posts GL entries collapses control boundaries, thus require separate service accounts and dual approval.



MFA vs unattended bots. Many legacy UIs cannot handle federated SSO; work-arounds (hard-coded cookies, bypass groups) create audit gaps.



Data residency & GDPR. Screen-scraped data cached in bot memory or local temp folders must follow the same retention rules as the system-of-record.




Security frameworks now list RPA under privileged automation requiring the same controls as service accounts or admin scripts.



5. High Technical Debt Over Time



Every new script spawns a parallel shadow process that diverges from the official system roadmap.




Version sprawl. Multiple teams fork the same workflow, leading to divergent selector logic and library versions.



Orphan bots. When the business retires a report or changes a field, older bots continue running and posting stale data until a failure surfaces.



Change-impact snowball. A single ERP patch can break dozens of downstream bots—each fix re-introduces risk if not regression-tested together.



Delays to real transformation. Leaders postpone API programmes because “the bot works,” compounding integration debt and blocking AI/analytics adoption, as recent research warns.




Best Practices for RPA in Legacy Environments



Successful RPA programmes in legacy settings share a common trait: they treat bots as carefully governed, short-term scaffolding that unlocks quick wins while long-term integration work is under way. That’s why we’ve gathered the top best practices for implementing RPA on legacy systems:



Treat RPA as a bridge, not the destination



Before you build the first robot, agree on what will eventually replace it: a published API, a vendor upgrade, or a wholesale re-platform. Capture that exit plan in the business case and review it at every steering-committee meeting. Time-box the bot’s service life (e.g., “sunset in 24 months or when the ERP moves to S/4HANA”) so the organisation doesn’t grow comfortable postponing real modernisation.



Prioritize stable, rule-based workflows



Legacy UIs that change quarterly are manageable; ones that change nightly are a maintenance nightmare. Score candidate processes on UI volatility, data quality, and exception frequency. Automate only those with well-defined inputs, deterministic business rules, and predictable screen layouts. Anything that requires constant human judgment—or is in the middle of a redesign—should stay on the backlog until it stabilises or gains an API.



Document bot logic alongside business SOPs



Treat every robot as part of the operating procedure, not as a hidden script. Store Process Definition Documents (PDDs) and annotated screenshots in the same repository as the source code. Use version control (Git, SVN, or the vendor’s repository) so you can trace changes, roll back faulty deployments, and hand over maintenance cleanly when staff rotate. Include a runbook with login details, data dictionaries, and contact points for each upstream and downstream system.



Combine RPA with process mining



Process-mining tools ingest system logs to visualise the “as-is” workflow, surface rework loops, and quantify time-saved per task. Use these insights to confirm a bot’s ROI, discover adjacent tasks worth automating, or identify steps that should be eliminated entirely, sometimes making the bot unnecessary. Periodically re-run mining after go-live; if throughput no longer justifies the bot licence or if the root cause has been fixed upstream, retire the automation.



Plan for exception handling



Even the best-engineered bot will hit edge cases like invalid data, pop-up errors, unexpected downtime. Build try/catch blocks that capture screenshots, log detailed error messages, and route the case to a human work queue (e.g., an Attended Bot Console or a ServiceNow ticket). Design SLAs for how quickly exceptions must be cleared and feed resolved cases back into bot training so the failure rate drops over time.



Separate the system-of-record from the automation layer



Whenever possible, keep bots stateless. Write data back to the authoritative database immediately instead of caching it in files or variables between sessions. Store business rules in a decision engine (DMN-based or BRMS) rather than inside the robot script; that way, when the rule changes, you update one central table instead of redeploying dozens of bots. This separation prevents “business logic creep” into the RPA layer and makes the eventual cut-over to APIs much smoother.



Additional technical safeguards




Credential vaulting: Integrate with enterprise secret-management tools and rotate service-account passwords automatically.



Self-healing selectors: Use vendor features that re-detect UI elements after minor layout changes, but still schedule quarterly regression tests.



Telemetry & KPIs: Stream bot logs to a SIEM or monitoring platform and alert on latency spikes, failure counts, and queue backlogs.



Governance board: Establish an RPA Center of Excellence to enforce coding standards, peer reviews, and retirement criteria.




RPA Platform Examples with Legacy Support



UiPath has the deepest native mainframe toolkit: its Terminal Session activities talk TN3270, TN5250 and VT hosts directly, so you can automate AS/400 menus or 3270 COBOL screens without a third-party emulator. The wizard screens each field as rows × columns, letting you build selectors that survive minor cursor shifts; a self-healing engine then re-maps those selectors whenever the host window moves.



Automation Anywhere approaches legacy automation through “surface automation” and dedicated green-screen packages. Bots key data into 5250 or VT100 terminals while business users feed them inputs via modern HTML forms or spreadsheets, creating an API-less bridge between vintage ERP modules and cloud workflows.



Blue Prism offers a full Mainframe integration spy-mode: when you model an emulator window, the platform overlays an 80 × 24 grid (or any host geometry) so you can latch on to specific row/column coordinates. Under the hood it speaks HLLAPI or similar terminal protocols, giving you reliable selectors even when the emulator runs inside Citrix or RDP.



NICE NEVA (NICE Employee Virtual Attendant) focuses on attended automation for contact-centre and back-office staff who still live inside legacy CRMs. A NEVA desktop bot pops up context-aware actions—copying customer data from a green screen, pasting it into a web CRM, or triggering after-call workflows—without requiring any back-end changes.



Kofax / Tungsten Automation positions its RPA suite as an integration layer for heavy ERP estates. Ready-made SAP connectors pair with desktop robots that can drive thick-client or terminal sessions, enabling invoice capture, HR onboarding or order-to-cash flows even when the underlying ECC screens expose no APIs.



Together, these vendors demonstrate that legacy system integration with RPA is no longer an edge case: each platform now treats mainframe and green-screen automation as a first-class citizen, providing terminal adapters, selector grids, and orchestration hooks to keep bots resilient while you modernise in the background.



When to Use RPA – and When Not To





Use RPA If:



You need automation quickly to relieve manual workload.



The system has no APIs or vendor support.



Processes are stable & repeatable; screen changes are predictable.



Budget constraints prevent a full rebuild, but savings are urgent.





Avoid RPA if:



You already plan a long-term system integration or rewrite within 12-18 months.



You can expose or wrap APIs (e.g., via an ESB or REST)



UI changes often and unpredictably, breaking selectors.



The migration project has begun and dual-maintenance would double effort.





Conclusion



“RPA for legacy systems” is neither a silver bullet nor a stop-gap gimmick. When applied to the right processes – stable, rule-driven, high-volume – it automates legacy applications with RPA faster and cheaper than code-heavy alternatives, unlocking quick wins while you design a sustainable integration roadmap.



Yet every benefit comes with caution: robotic process automation in legacy environments can mask underlying system fragility, create governance headaches and incur license costs. Treat bots as temporary scaffolding that keeps operations humming while architects expose APIs, build microservices or deploy modern ERPs.

How to Do a MySQL 5.7 to 8 Upgrade: MySQL Upgrade Steps



Initiating an upgrade MySQL 5.6 to 8 comes with a significant performance advantage offered by the latest version. 



Note that upgrading to the latest release within a series is recommended before moving to the next version. For instance, if you have MySQL 5.6 version, upgrade to the latest MySQL 5.7 release before transitioning to MySQL 8.0. Direct MySQL 5.6 upgrade to 8 version is not supported. Once a release series reaches General Availability (GA) status, upgrading within that series is fully supported.



Note on Obsolete Elements in MySQL 5.6



When upgrading from MySQL 5.6 to 8, it's also important to be aware of certain obsolete data types and features. Data types like YEAR(2), ENUM, TINYTEXT, MEDIUMTEXT, LONGTEXT, and clauses such as NATIONAL, CHARACTER SET, and COLLATE are considered outdated in MySQL 8. It's advisable to use lookup tables with foreign keys instead of ENUM, and prefer VARCHAR or TEXT for text types. For character sets and collations, using the CHARACTER SET and COLLATE options within column or table definitions is recommended.



Now, here are the MySQL upgrade steps.



Step 1 - Create a Backup of Your Current Database




Stop the MySQL service to ensure a consistent backup.



Backup entire MySQL path. his precaution ensures a safety net for your data, allowing for a straightforward restoration in case of any issues during the upgrade.

In today’s rapidly evolving technological landscape, a skilled partner must stay at the forefront of modern technologies. They should have expertise in cloud infrastructure and providers such as AWS, Microsoft Azure, or Google Cloud, along with containerization tools like Kubernetes and Docker. 





Additionally, their proficiency in microservices architecture and programming languages like Java, Python, or .NET ensures that your systems are future-proof and scalable. For example, a partner capable of migrating a monolithic application to a microservices-based system can drastically improve scalability and operational agility.





Security and Compliance



Security breaches can be costly, both financially and reputationally, making robust security measures a non-negotiable aspect of modernization. A good partner will conduct vulnerability assessments, implement encryption protocols, and ensure compliance with regulations like GDPR, HIPAA, or PCI DSS. For instance, a modernization partner assisting a financial institution should have proven expertise in securing payment gateways and protecting customer data during migrations.



Client References and Success Stories



Partners with a strong track record often share client success stories and testimonials. For example, a partner who modernized a retail platform to handle millions of transactions per second while reducing latency can demonstrate their technical capabilities. Ask for specific examples where they delivered tangible results, like reducing operational costs by 30% or cutting downtime by 90%.



Cultural Fit and Communication



Modernizing legacy applications often requires close collaboration, making cultural alignment critical. For example, a partner with a customer-first approach and a clear communication framework will ensure smoother interactions and quicker resolutions. 



Scalability and Flexibility



Business needs to evolve, and your partner should be capable of scaling their legacy application modernization services accordingly. For instance, if your project grows from migrating a single application to replatforming your entire infrastructure, your partner should have the resources to adapt. A partner offering flexible pricing models, such as pay-as-you-go cloud services, can also help control costs while scaling operations.

### Guide to Legacy Application Migration: All You Need to Know

Organizations that are quick to embrace change and adapt to newer business environments stand a greater chance of becoming frontrunners in their respective industries. When scaling or striving to compete favorably, companies must make the hard decision to modernize legacy applications. Often, legacy applications present integration challenges with new platforms, systems, or processes, cutting you off from modern analytics and the benefits of a cloud-first strategy. And this is not to mention the frequent server hardware or application downtimes that can result in as much as $300,000 in losses within just one hour. 



If this nearly describes your present scenario, you might decide moving the legacy application to a modern computing environment. However, this is easier said than done, thanks to the complexity and demanding nature of a typical legacy application migration project. Even if you are considering legacy migration services like re-platforming or rewriting the application, you'll still need to move its data, and Gartner estimates that 83% of all data migration projects fail, while 50% experience budget overruns. 



So, what do you need to consider when migrating legacy applications? And what are the errors, risks, and challenges that you’ll likely encounter? Find out more in this in-depth guide. 



What is a Legacy Application?



The term legacy application is a collective reference to on-premise business systems or software programs that are likely obsolete or outdated but still in use. These applications may include sales systems, Customer Relationship Management (CRM) software, QuickBooks, or industry-specific software that’s critical to an organization’s day-to-day operations. 



According to Gartner, legacy application it's an IT system that may be based on outdated technologies, but is critical to day-to-day operations of organizations.



Although a legacy application might be the bloodline of all operations, the system can present various challenges, including high maintenance costs. This is because the system might require endless tweaks and patches to align it with modern business requirements or technology integrations. That said, consider the following factors to determine if your application is legacy and might require rewriting or replatforming:




Age: Legacy applications are older by design and use and have been operational for a considerable period, say a decade or more. In other words, the age of the application might be used to determine its legacy status. 



Business impact: What’s the application’s impact on your business? Can you count on its performance, reliability, or security features? If the answer is no and the limitations are cutting into the profits of your business, the application might be a legacy system.



Technology stack: A business application becomes a legacy system if the technology stack powering it becomes outdated or obsolete. This includes frameworks, libraries, or programming languages with deprecated technical support. 



Compatibility with other systems: A legacy system might face compatibility issues and might require an advanced workaround to connect it with modern technologies, platforms, services, or computing environments, such as AWS. If this describes your app, then it’s a legacy system. 



User interface and experience: Watch out if the application provides an inferior user experience compared to modern contemporary business applications. This can manifest in unresponsive commands or clunky user interfaces that have your team complaining every time. If that's the case, the app proves its legacy status.

When Do You Need Legacy Application Migration?



There are specific business scenarios that may prompt you to migrate legacy applications, including: 








When leveling up for the competition: The modern business landscape is highly competitive, and the last thing that you want is lagging in terms of innovation. By migrating to a highly flexible and scalable solution, your business can integrate modern technologies to scale faster and provide a more personalized customer experience. 



When engaging remote teams: Legacy systems might require employees to access certain applications via in-house desktop software, which might hinder effective remote collaboration. In that case, migrating to a more flexible solution is a viable option since it will enhance your team’s digital mobility. 



When you can’t find and hire the right developers: Legacy application migration might be difficult if you can’t find developers with the right skill sets to optimize or maintain your old systems, especially if they are built using custom old-school programming languages.

Benefits of Legacy System Migration to Web



Web applications continue to supplant desktop apps, and we believe there are several good reasons for moving to a web application from a desktop. The benefits of legacy system migration to the web are real and tangible:



Cross-platform availability



When creating or modifying desktop applications, it is necessary to create multiple versions at once. This applies not only to different types of OS — Windows, macOS, and Linux but also to different versions of these systems. There is no such problem with web-based applications, which greatly simplify the development process and reduces development costs. Web applications enable remote access from basically any device, which opens up support for most operating systems, whether desktop or mobile. Moreover, web-based applications can give employees greater flexibility in where they work, reduce the amount of busywork involved in using the system, and allow your teams to respond quickly to any emergencies that arise.







 VIEW CASE STUDY



Smoother updates



The software must constantly evolve, especially when it comes to apps intended for external customers and not for internal use in the company. Introducing new functionality requires app updates, and while web applications are updated centrally on the server, desktop users will need to download the new version and reinstall the app. For development teams, web applications reduce the hassle associated with new deployments, bug fixes, upgrades, and feature implementation.

Data security



On the one hand, storing user data on their own devices makes it more difficult for potential attackers to gain access to the data. But on the other hand, all this data can be easily lost in the event of a computer failure, while a web application will save all the latest changes on the server.



Lower maintenance costs



The advantage is obvious — you won’t have to invest money in keeping outdated systems on life support.

Step-by-Step Legacy Application Migration Process: From Legacy System to Web Application



A successful application modernization strategy should be built around opportunities for business growth. It should be driven from the top down as a core business strategy, not simply some effort driven by IT. Next, we’ll cover the essential steps of legacy application migration.







Step 1: Start with the Analysis



You need to evaluate your system’s current state and the way it behaves to spot problem areas. This way, you’ll be able to understand which issues you’ll have to fix before, during, or after the migration process. Pay special attention to any potential data saving and security issues.



Step 2: Identify Areas for Legacy Modernization



Oftentimes, businesses view migration solely as a way to facilitate upgrading the system. Migration and modernization aren’t necessarily mutually exclusive: you don’t have to migrate the entire system at once. Instead, you can only migrate some of the system’s components and see if any of your current system’s functions will benefit more from on-premise modernization. This could save you a significant amount of costs compared to “all-in” migration solutions.



Step 3: Simplify Things



The more complex your legacy system is at the moment, the more difficult it might be to migrate it. For instance, migration may cause some architectural problems if the current infrastructure is too massive. Migration is a big change on its own, so it won’t hurt to analyze your system’s current state and implement some minor, simplifying changes along the way.



Step 4: Define an Approach



There are two main options available to anyone considering an application migration, each with its pros and cons. Some businesses try to replace systems in one go, with one "big bang" at the end when an old system is turned off and a new one is turned on. Another option involves taking a staged approach and moving the app over piece by piece. Regardless of the approach, here are the three most common technical migration and modernization techniques for you to consider:




Encapsulation




This approach involves packing an existing desktop application into a more user-friendly web service. That is, you’ll need to build the web UI and use the APIs to connect it to the functionality of the desktop application. 



This is the quickest and, most importantly, the most predictable approach to web-based modernization. However, it is only applicable only if the current application is in good technical condition and has up-to-date functionality. Otherwise, you’ll need to re-engineer the app or at least some of the app’s components.




Codebase transformation




This approach involves converting lines of code of the desktop-based legacy application to transform it into a web application. There are plenty of automatic tools to do most of the hard work for you, but they are not yet advanced enough to deliver a fully working solution. Indeed, these tools can simplify and speed up the process, but only if you have a team of skilled developers who can handle important data, add the necessary code, and put it all together correctly.




Building a new custom web application




If the current state of your desktop application leaves much to be desired and you have sufficient budget for a complete transformation, it will make sense to create a prototype of a web-based version of the desktop app. This will allow you to rethink the app's architecture, consider the possibilities of using cloud solutions, and build an application using the latest LTS technologies and platforms. 



There are, though, a few factors to consider with this approach:




Data migration. You will need to transfer your current application data and accounts to a new platform, and this should be planned in advance;





Cloud or not, as the cloud may not always be the best solution for a business;





Additional training, since maintaining a web solution requires a different approach than with a desktop solution, with at least a different tech stack;





Minimal viable product to start with, since it’s better to start by implementing core features and then improve the product in iterations so that the migration is smoother and you get exactly the solution you need.

Key Legacy Application Migration Strategies with Use Cases



Choosing the right migration strategy depends on organization's goals, budget, and technical constraints. Here are five key strategies, each with its own use case, to guide your legacy application transformation.



1. Replatforming



Replatforming involves making minimal changes to an application to move it to a new platform, such as transitioning from on-premises infrastructure to a cloud environment. This strategy preserves core application functionality while taking advantage of modern infrastructure benefits like scalability and cost savings.



Use Case: A manufacturing company uses a legacy ERP system running on outdated servers. By replatforming the ERP to a cloud-based infrastructure (e.g., Microsoft Azure or AWS), the company can improve system performance and reduce hardware maintenance costs while keeping the core application logic intact.







2. Refactoring



Refactoring focuses on optimizing and modifying the application’s codebase to improve performance, scalability, or maintainability without changing its core functionality. This strategy is suitable when the business logic needs to remain consistent, but the technology stack requires updates.



Use Case: A financial services firm has a legacy trading application written in outdated programming languages. By refactoring the codebase to leverage modern frameworks and microservices architecture, the company improves system efficiency and makes it easier to maintain and enhance the application.







3. Rehosting



Rehosting, also known as “lift and shift,” involves moving an application as-is from one environment to another, such as migrating on-premises applications to the cloud. This strategy requires minimal effort and is often used for quick cloud adoption without making changes to the underlying code.



Use Case: A retail chain with a legacy inventory management system running in an on-premises data center decides to rehost it on a cloud platform. By doing a straightforward lift and shift, the company gains the advantages of cloud scalability and cost optimization without disrupting operations.







4. Rebuilding



Rebuilding involves redeveloping an application from scratch using modern technologies and architectures. This strategy is often chosen when a legacy application no longer meets business requirements or is too outdated to modernize legacy applications effectively.



Use Case: A healthcare provider has a legacy patient management system that lacks integration capabilities and cannot support mobile access. The organization decides to rebuild the application using a cloud-native approach, adding new features like mobile access, advanced analytics, and secure data sharing.







5. Redesigning



Redesigning is a more extensive approach where the entire application architecture and user experience are reimagined to meet current and future business needs. This application modernization strategy focuses on enhancing usability, performance, and system capabilities.



Use Case: An e-commerce company with a dated customer portal finds it difficult to provide a seamless online shopping experience. By redesigning the portal with a focus on mobile-first design, personalized user experience, and integration with third-party services, the company significantly improves customer satisfaction and engagement.



Conquer the Last Mile of Business Success with Legacy to Cloud Migration 



After the transfer of legacy applications to the web, you might want to consider migrating to the cloud. Cloud migration to Azure or AWS is not only a logical step to follow but also offers a suitable modern solution for your legacy app. For many organizations, moving to the cloud after migrating legacy apps translates to instant business benefits and opportunities that enable them to optimize operations and ascend to newer heights. These benefits include:



Increased flexibility and scalability 



Exploring cloud computing after legacy software migration allows your company to scale or downsize resources as much as needed, providing greater flexibility to respond to dynamic market demands and business needs of key stakeholders. Additionally, you can expand the capabilities of your paid plan in terms of computing power, storage, and other complimentary resources without incurring significant overhead costs. 



Improved security and reliability 



Reputable cloud service providers, such as Amazon AWS and Microsoft Azure, have robust security measures in place to guarantee the safety and reliability of their infrastructure. As a client, you can always rest assured that experts will identify and mitigate any cybersecurity threats before they jeopardize your cloud-based applications. Most importantly, you can leverage built-in backup functionalities to ensure business continuity in the event of a disaster. 



Innovation and competitive advantage



Legacy to cloud migration positions your business to integrate and leverage application modernization trends, such as artificial intelligence (AI), big data analytics, and machine learning (ML). Connecting your business operations with these technologies means you can tap into real-time data analytics, innovate products and services, or automate processes to gain an upper edge over the competition. 



Enhanced accessibility and collaboration



By leveraging legacy application modernization to the cloud, you increase the digital mobility of your team, allowing everyone to access important business resources from any location or device, provided they are connected to the internet. Moreover, cloud-powered business applications often feature real-time collaboration capabilities, allowing you to explore alternative hiring solutions, such as remote outstaffing.

Legacy System Migration Challenges You Could Face



Despite its benefits, legacy system migration to web applications is a complex process that has its own challenges. Let’s take a look at the major legacy system migration challenges for you to put them on your radar when planning the migration process.



Migration Can Slow Down Your Business Processes 



The legacy system migration approach implies analyzing, transforming, modifying, and introducing your workflows to a new environment, which is often a time-consuming task. This can affect your business operations during the migration period. Take time to plan how to perform the migration with the minimum amount of business disruption for all users involved.



Migration Can Cause Security Issues



While outdated legacy systems have their security issues as well, it's crucial that you deal with them before the migration process. Otherwise, you might end up with the same old security risks that weren't fixed or documented, and thus might expose your business to new potential threats in the future. 



Migration Requires Updating Data Values 



Legacy systems are often outdated not only in terms of software but in terms of data management as well: they store information that was valuable years ago but has no value for your business at the moment. It's better to clean and validate the data before moving on to the migration if you don't want to encounter irrelevant data during or after the migration process.



It Might Require Some Additional User Training 



If migration from the legacy system directly affects your employees’ way of doing their jobs, you need to spend some time and effort on helping them adapt to this new environment. This might affect your business as well, as the employees won’t be able to fulfill their duties as efficiently as before for some time.



Tips for Successful Legacy Application Migration



Before wrapping up, let us share some tips on what steps to take to make the migration of legacy systems to the cloud a bit smoother for your business.



Ensure Legal Compliance



Before you launch the legacy app migration process, make sure there aren’t any legal limitations to data migration to the web. Also, make sure to learn all the compliance requirements of your web data storage. 



Set Up a Solid Data Migration Strategy



Before starting the project on rehosting, rebuilding, or re-architecting, take some time to review your legacy database schema to identify whether and how to modify the data structure for the data to become accessible from the web.



Evaluate Infrastructural Limitations 



Is it possible for your system’s current infrastructure to seamlessly connect to the web? Does it have any elements that can possibly hamper the migration process?



Ensure the Security of Your Applications and Data on the Web



Make sure to have a hardware firewall, a software firewall, and an intrusion detection system (IDS) in place to ensure everything is securely protected. 



Pay Attention to the System’s Availability and Reliability 



Ensure that you have enough hardware resources to ensure minimal response time and the system’s ability to withstand the high load of simultaneous end-user requests and malicious attacks such as DDoS.



Prevent Possible Security Breaches 



Implement security measures such as multi-factor authentication (MFA) and advanced password policies during legacy software migration. 



Assess Potential Software Design Limitations 



This will help you evaluate legacy migration options and avoid many costly reengineering processes in the future.



Ensure the Compatibility of Third-Party Components 



Make sure that all your hardware and software components, including on-premise equipment, security keys, and third-party software license sets, are compatible with the web environment.



Come Up with Plan B 



This will help you roll back changes at any moment. Formulate a clear-cut plan to cover each step of the final migration to the web, and a rollback plan to revert to the original setup if things don’t work out at any stage of the process.

### Top Docker Desktop Alternatives: Replacement Guide

The Docker platform is all about app containers and containerization. If you’re new to containerization, it is a way of packing a software application and all its dependencies into a single image. Containers allow users to separate an application from its infrastructure, so the app works in a predefined way regardless of the environment. 



Docker Desktop was a free open-source platform preferred by developers. But in January 2022, the company introduced a subscription policy that requires licensing for commercial users. The implementation of that policy has led their previously devoted free users to search for other Docker alternatives for mac and windows that deliver just as much value as Docker, or even better. 



This article compiles a list of free Docker alternatives that can act as Docker replacements for your container ecosystem.



Docker and the Container Ecosystem



According to IBM, a container is a separate unit of software that stores an application’s code, its libraries, and dependencies. 



There is a widespread misconception that Docker is all about containers only.  Well, that’s not true and Docker is only part of the container ecosystem that consists of large, different projects. What unites the two is the requirement to meet the Open Container Initiative (OCI) and Kubernetes Container Runtime Interface (CRI) standards.

What is Docker?



Docker is a simplified platform for development, shipping, and running containerized applications. The platform provides an open-source engine that automates the deployment of any application in a lightweight, self-contained space for on-premises and cloud use.











Docker architecture overview











Docker was the first company to ever package the advanced Linux kernel features. This made development and deployment faster. Instead of building an entire server from scratch to run a service application, you could run a Docker container image on the host and start the application, using a few host resources in multiple environments.



An image is a read-only, organized collection of filesystem changes that form the basis of a container. A container is a runnable instance of an image. Each container has its own filesystem, memory, and network interface. Also, containers are much lighter than virtual machine (VM) images.















7 Reasons Why Developers Look For Docker Desktop Alternatives



Docker products are on a whole new level. Portability, isolation, scalability, consistency, repeatability, and automation are just a few features you can expect from Docker container tools. However, there is still a downside to using Docker tools. Below are some of the most common reasons why developers look for the Docker alternative for Windows or mac:



Security Issues



The first issue in Docker is the connection between services when it comes to routing, security, or detection. There is limited security in the Docker architecture itself. A user with access to the Docker daemon has root advantage over the host system.



Orchestration issues



Docker can’t manage the container launch order. Though it has an orchestration tool called Docker Swarm, its functionality is limited compared to powerful orchestrators like Kubernetes. Besides, Docker Swarm works only with Docker containers. 



Isolation issues



Docker does not provide 100% isolation of resources between containers. And, there could be a mess in the images repository as all the users have the power to change something.



Reliability Issues



The Docker daemon service is responsible for all the work with registries, images, containers, and the kernel. But, a single service means an increased risk of failure. When a daemon process fails, all the running containers are left on their own.



Firewall Issues



Docker interferes with the system firewall by adding its own firewall rules to the system. There is no reliable way to manage network access to the container through the firewall. Additionally, there is an issue when combining Docker with other services that try to manage the firewall, for example, with a VPN client-server.



Docker Hub Issues



Docker Hub registry contains both official and non-official images. Most of the non-official images are poorly built and have vulnerabilities. The authors of such images usually don’t provide any quality guarantees or support either.



Installation Issues



There are multiple ways to install Docker. But some features may stop working or may work unexpectedly when doing the custom installations.



Docker Desktop and What Has Changed



Docker Desktop has recently caught the attention of the container community after the new changes in its subscription policy. 



Docker Desktop (DD) is an all-in-one application for mac or Windows environments that enables building and sharing containerized applications and microservices. Docker Desktop includes Docker Engine, Docker CLI (Command Line Interface) client, Docker Compose, Kubernetes, just to mention a few.



Docker Desktop on mac and Windows is a way to run Linux (create a Linux VM) so that Docker Engine can work.















What has changed in the Docker licensing policy?



The Docker company made an announcement in August 2021 that it would be making changes to its Docker Desktop subscription terms. The change was to become effective in January 2022 but there was a grace period in between for Docker Desktop users to decide on a subscription plan if they want to continue using the Docker Desktop license. Otherwise, they will have to switch to other free Docker alternatives.



The officials expressed that these changes are vital to the improvement of their product and scaling their business. With Docker Desktop now reaching 3.3 million installations, the company is one big step closer to its goals.



AngularJS officially reached the end of support in December 2021. Here's what you should do. Guide for Upgrading AngularJS to Angular with an Example of Real Case 



The New Subscription Policy



Based on the new subscription policy, only the Personal subscription plan is free – it is available for small businesses, individual use, and non-commercial open-source projects. If a company, however, has more than 250 employees or its revenue is greater than $10 million, it will have to use one of the paid subscriptions: Pro, Team, or Business. Simply put, large business users must go for a Docker Desktop enterprise license to get additional features – secure software supply chain management, centralized policy visibility, and controls. Smaller businesses will enjoy Docker Desktop for free.




Note: If you don’t need Docker Desktop, then nothing has changed for your business – you can still choose any tool (Docker, Podman, CRI-O, etc.) for container creation and orchestration.




When do you really need Docker Desktop?



Docker Desktop is for people who crave a simplified installation process but don't want to use the command line. Docker Desktop facilitates easy Docker setup and integration with WSL (Windows Subsystem for Linux).



Speaking of Linux, Docker Desktop may still not be fully available for Linux users. The thing is DD is supported on mac and Windows only. But to use Docker in non-Linux operating systems, developers need a Virtual Machine and that’s what Docker Desktop does. Everything else (Docker CLI, Docker Engine, and other Docker tools) remains free and open source under the Apache v.2 license.



 VIEW CASE STUDY  



Docker Desktop Alternatives



When using Docker Desktop you’ll probably find the issues in Docker mentioned above. Some of these issues were partially solved with the paid subscriptions. For example, the Business plan provides centralized management, enhanced security, and SAML SSO in the near future. But others (together with the new per-user-per-month tariffication) of the DD, may force you to search for alternatives to Docker Desktop.



You can replace Docker Desktop with one of the following alternatives:



Podman vs Docker



Podman is a popular Docker Desktop alternative that provides a simple and familiar interface for managing containers. It allows you to run, manage, and deploy containers using the Docker command-line interface (CLI) syntax, without the bulky weight of using a separate daemon to manage containers. Podman vs Docker allows users to create, manage store and deploy Linux Kernel, and its containers independent of any central process. Instead, the containers are started as child processes of the Podman process, heavily using user namespaces and network namespaces. Podman also supports rootless mode, which allows non-root users to run containers without needing elevated permissions.



Another remarkable advantage of Podman, except being aDocker alternative for Mac, is that Podman addresses the security issues with Docker. Additionally, Podman uses traditional Linux process management and security features, such as cgroups and SELinux, which can provide enhanced security for containerized applications.



Podman also has built-in support for Kubernetes, which means you can use Podman as a drop-in Docker replacement with Kubernetes deployments. This makes it easier to migrate from Docker to Podman in Kubernetes environments without major modifications to existing deployment configurations.







Rancher Desktop



Rancher Desktop, an open-source application and free Docker alternative for mac, Windows, and Linux which simplifies building, pushing, pulling, running container images, and also includes Kubernetes. It’s simple to use and has a built-in GUI.



Rancher Desktop is also compatible with multiple cloud providers, making it easier for developers to deploy their applications to production environments. The key difference between Docker and Rancher Desktop is that Rancher has a broader focus on Kubernetes and multi-cloud deployment. 



Containerd



Containerd is a container runtime that is part of the Docker ecosystem but can also be used as a standalone alternative. It provides a lightweight and high-performance option for running containers and is compatible with the Open Container Initiative (OCI) runtime specification.2



Containerd is designed to be a simple and lightweight container runtime focused on doing one thing well - running containers. It provides essential container runtime functionality without the additional features and complexity that Docker offers, which makes it a good fit for users who prefer a minimalistic approach or have specific use cases that don't require all the features that Docker provides. It follows a modular architecture, with a clear separation of concerns between its components. This modular design allows users to choose and swap components, such as containerd's built-in container image service and container runtime, with other components that fit their specific needs. This gives users more flexibility and customization options compared to Docker, which is more monolithic in its architecture.



Minikube



Minikube is another excellent Docker replacement for local container development. It is specifically designed for Kubernetes, a popular container orchestration platform. Minikube allows you to run a single-node Kubernetes cluster on your local machine, making it easy to develop, test, and deploy containerized applications using Kubernetes. With Minikube, you can create and manage Docker containers as part of your Kubernetes cluster, giving you a seamless experience for Kubernetes-based development.



Minikube is part of the Kubernetes ecosystem and is designed to work seamlessly with Kubernetes, which is one of the most popular container orchestration platforms. Minikube provides an easy way to spin up a local Kubernetes cluster, allowing developers to test their applications in a Kubernetes-like environment before deploying to a production Kubernetes cluster.



It provides a simple and easy setup process, allowing developers to quickly set up a local Kubernetes cluster with a single command. It also provides management commands to start, stop, and delete clusters, making it easy to manage local Kubernetes environments.



LXD



LXD is a containerization technology that provide an alternative to Docker Desktop for Linux users. LXD is more similar to traditional virtualization technologies like VMs, where you can run complete OS distributions with their own init systems, users, and processes. This makes it suitable for running workloads that require full OS-level isolation and separation, such as running multiple Linux distributions with their own kernels on a single host. LXD also provides features like container snapshots, live migration, and clustering, making it a powerful tool for advanced container use cases.



LXD is designed for running stateful applications that require persistent storage and state preservation across container restarts. It provides better support for running databases, file servers, and other stateful applications, as it allows for the management of persistent storage volumes and supports features like live migration and snapshots. It also provides a unified management experience for both containers and VMs, making it easy to manage and configure both types of virtualization technologies in a single interface. This can be beneficial in scenarios where you need to run both containers and VMs on the same host.



New alternatives for 2024: Buildah and Kaniko



Buildah is a tool focused on building container images without necessitating a complete container runtime environment. It integrates well with Podman, making it a versatile option for developers who need to create and manage container images within CI/CD pipelines. Buildah offers detailed control over the image-building process, ensuring efficient and streamlined workflows​​.



Kaniko is a robust tool designed to build container images within Kubernetes clusters, eliminating the need for a Docker daemon. It is particularly optimized for Kubernetes workflows, enabling secure and efficient image creation directly in cloud-native environments. Kaniko excels in building container images from Dockerfiles in environments where it is not feasible to run a Docker daemon, such as in Kubernetes clusters. This tool supports advanced features like multi-stage builds and cache layers, making it highly efficient for continuous integration and continuous deployment (CI/CD) pipelines.



What To Consider Before You Choose the Right Docker Desktop Alternative that Will Fit Your Requirements  



Choosing the right alternative to Docker Desktop depends on your specific requirements. Here are some considerations to help you make an informed decision:




Features and Functionality: DD provides a rich set of features, such as container orchestration with Docker Swarm, image layering, networking, and volume management. When considering alternatives, ensure that they offer the features and functionality that are relevant to your specific use case.





Containerization vs. Virtualization: DD uses containerization, which allows for lightweight and efficient isolation of processes while sharing the host OS kernel. Virtualization, on the other hand, creates a separate virtual machine with its own OS. If you need lightweight and fast deployment, containerization may be a better fit. If you require stronger isolation between processes or need to run different operating systems, virtualization might be more suitable.





Ecosystem and Community: Docker has a large and mature ecosystem with a vast community of developers and users, which means extensive documentation, support, and a wide range of Docker-compatible images available in the Hub. When considering alternatives, check for the size and activity of the community, available documentation, environmental variables and the overall ecosystem to ensure good support and a strong community.





Ease of Use: Docker Desktop is known for its user-friendly command-line interface and easy-to-understand Dockerfile syntax for building container images. When evaluating alternatives, consider the ease of use, the learning curve, and the developer experience. Look for tools that offer similar simplicity and ease of use.



Performance: Docker runs  efficient and high-performance containerization technology. When evaluating alternatives, consider the performance characteristics, such as container startup time, resource utilization, and overall performance overhead.





Platform Support: DD is available for a wide range of platforms, including Linux, Windows, and macOS. Make sure that the alternative you are considering supports the platform(s) you are planning to use.




Consider ModLogix Your Trusted Partner for Docker Replacement



The above list is not conclusive. There are several other containers out there that are free Docker alternative for developers. If you are still not sure about which option is best for you, or would like to have an expert’s opinion to determine the best Docker alternatives for Windows or mac. We are here to help.



ModLogix is a company that specializes in upgrading legacy software. Our goal is to help our customers upgrade their existing applications and take advantage of the latest technologies and architectures, while also improving quality and maintenance. 



Final Thoughts



In the container ecosystem, there are no “Docker containers”, there are just “containers”, and there are no “Docker images”, just  “container images.” You are free to use any alternative containers to Docker, as long as it follows the industry standards around container formats and runtimes.



Please remember that Docker is a tool. To use it effectively, you need an experienced development team or software consultant. This team that understands Docker commands will know how to mitigate any issue in Docker. Sometimes, the best option is to use lightweight virtual machines. In other cases, using more specialized container tools may help. It all boils down to the purpose, project goals, and application features.



The only Docker product that is without a fully equipped substitute is Docker Desktop alternative for mac and Docker Desktop alternative on Windows. But, it’s only a matter of time before other companies launch products that can substitute DD. For now, try analyzing if the free Docker alternative provides any additional value for your business or not. If you don’t use any Docker Desktop features beyond what Docker itself is offering, it’s worth considering other options. But if there is significant additional value, it’s worth paying for the out-of-the-box functionality.

### List and Risks of Outdated Software Technologies in 2022-25 [upd] | ModLogix

Do you remember the Delta Air Lines’ computer glitch that saw passengers stranded and more than 4,000 flights canceled? This was caused by a legacy computer crash. Delta Air Lines had to pay a large price for the outage, approximately a whopping $177 million at the least. 



Delta Air Lines’ case is just a snippet of how software obsolescence is costing companies. In the US, organizations report nearly $1.8 billion in annual productivity losses due to the use of outdated technology. What’s more, the effects of out-of-date technology reflect in customer turnover too. A recent Microsoft poll shows that 91% of customers consider terminating business relationships with companies that use obsolete software technologies due to security and privacy concerns.



From the foregoing trends, it sounds prudent to understand examples of obsolete technology and the risks of using outdated technology. Dive into this article for in-depth insight on the impact of outdated software technologies and see the comprehensive list of frameworks and programming languages that become obsolete in 2025.



Outdated Technology Definition




“An information system that may be based on outdated technologies, but is critical to day-to-day operations”




GARTNER



Outdated software technology (legacy or obsolete) is a concept that encompasses software, hardware, programming languages, services, or practices that are no longer used.



It's common to come across big companies using technology that is obsolete.  Many of them have invested in custom software solutions that they are not willing to change. For instance, it’s in the public domain that some banks still rely on old tech. In addition, most nuclear power plants are also running on obsolete software technologies. 



Sounds like a pitfall for any business — being willing but unable to move forward. But despite this, there 



Here are vital signs that indicate you are using outdated software technologies in your organization: 




Closure of software companies, 



Abandonment of projects, 



Replacement by new versions, 



Competition from similar products, 



Introduction of disruptive technologies 



A slow development lifecycle




However, as you know, the software landscape is ever-changing. Hanging on to obsolete software in this kind of environment may threaten the business in any kind of industry.







Risks of Using Outdated Technologies



If it's still working, no need to fix it or at least take a look at it, right? Wrong! This might be true in many cases but not when it comes to business. Running a business using obsolete technology in 2022 is not only disadvantageous but also risky, not only to the bottom line but also to people’s lives. 



Given the ever-increasing demands on software infrastructure, obsolete systems that seem to be working perfectly now will eventually give in. This, compounded with other problems associated with the use of outdated technology, exposes your business to various risks. Some of risks of outdated software include:



1. Incompatibility Issues





One of the biggest disadvantages of outdated technology is incompatibility. This can downplay an organization’s efforts to modernize its operations and IT infrastructure. Typically, developers write a software system to suit the technologies, software, and hardware that are in use at their time of development. This doesn't mean that older software will not work with newer tech. It may, however, like yoking an old cow with a younger cow together, this arrangement may not produce the best out of the system.  





Moreover, incompatible legacy systems will not pass the latest quality assurance tests for the legacy codebase. If your business serves a highly regulated industry, you may need to forego some plans or stall scaling.





















So, how does this pose a threat to your business? Technology incompatibility translates to a lack of standardization and governance in your infrastructure. In return, this affects the overall performance and convenience of the IT infrastructure in terms of cost-efficiency. You end up with a choice of either keeping operations in the past or straining to keep up with emerging evolutions.



Do you want to deal with technology incompatibility? Well, integration is the answer. How to Effectively Conduct a Legacy System Integration 



2. Low Productivity Due to Unreliable Software Performance





Dead technology is bound to fail or cause downtime in one way or another—even if it’s not today. A few years ago, Paris Orly International Airport came to a standstill after a Windows 3.1 operating system in the control tower failed.



The system which debuted in 1992 and became obsolete in 2001 saw tens of planes grounded for the better part of the day. This is just one of the many system failures that paralyze productivity in international airports or other public and private organizations. It’s worth noting that a single system failure, in this case, affects productivity across tens of companies, and nations.





Besides halting operations suddenly, outdated technology is also usually slow in terms of updates and tasks execution when compared to newer tech.  Microsoft notes that businesses leveraging outdated programming languages can lose up to seven days of productivity per calendar year. What's more, obsolete but functional computers that are older than four years can result in up to 21 hours of productivity loss due to frequent updates, repairs, and security patches.  





3. Data Loss When the Software Fails





Legacy systems were developed years ago, at a The Federal Emergency Management Agency (FEMA) notes that 40% of businesses that suffer data loss end up shutting down operations indefinitely. Data loss can happen to anyone, especially if it emanates from a natural course, such as laptop theft or accidental deletion.





Fortunately, businesses can still mitigate these threats through encryption and regular backups to the cloud. Unlike their modern counterparts that come with these in-built features, unsupported technologies may be deficient in this regard, and set you up for data loss because they store data in spreadsheets and local storages. In a world where data is the new oil, you can hardly afford such a loss.





We recommend you replace older tech with a new version to mitigate this risk. Even better, top-tier vendors, such as Microsoft constantly offer technical support on security patches and upgrades.



4. An Easy Avenue for Cybercriminals





If there is something that hackers hope for the most when preying on unsuspecting companies is coming across obsolete technology. Outdated software is usually vulnerable because it doesn’t feature the new security patches released by the vendor.



The security vulnerabilities of legacy systems are also usually very easy to find as they are, usually, well documented and published by the vendor or developer.





While it is harder to attack new or up-to-date systems, cybercriminals will not hesitate to design malware programs that can exploit the system’s vulnerabilities.





Even though there are many more worrying examples of threats from obsolete technology, a surprising number of companies continue to rely on legacy software. 5 Examples of Legacy Systems: Where and Why Ones are Still in Use 



While it might take hackers a quick and easy expedition to attack your outdated system, sometimes out of fun, your business stands to suffer a bigger blow. Malware attacks cost US businesses up to $2 million every year, with experts projecting more attacks in the near future, given that we have witnessed an 87% increase in these cases in the past decade alone. You’re looking at a $1 trillion ballpark in a five-year projection.



5. Operating System Bugs



The operating system is essentially the environment in which all of your software operates and interacts in. Bugs may be prevalent in your operating system if you’re leveraging obsolete programming languages. Modern business practices entail integrating various software systems, such as payroll, database, or project management. In that case, a series of old coding languages in one application is enough to crash the whole operating system. If not, the chances of corrupting your system still remain high. 



How much do you think you'll lose in terms of performance and productivity if the vendor doesn’t resolve the issue in time? That said, it sounds more prudent to run your business on the newest version of the software you’re currently using.



Technologies That Are Already Obsolete in 2025



2021 saw many technologies become obsolete, thanks to the rise of several new-generation devices and innovations. Although many businesses welcomed this, there are a couple of systems that will fizzle out completely and may not see the end of 2022. Here are the most remarkable end-of-life announcements.




Oracle 18 Database




Unlike other Oracle Database versions that had two releases, Oracle 18c Database exists in one version only, released in February and July 2018. The software that had various marquee features, such as polymorphic table functions, approximate Top-N query processing, and active directory integration became obsolete in April 2021. Companies that rely on this technology no longer benefit from vendor release updates that mitigate security, regression, and functionality risks.





Oracle 18c has been found to have a lot of vulnerabilities. Some of these can allow both low and high privileged attackers to access, read and change the data in a database. Since trust is important, this can prove costly to an organization’s operations.





Businesses that leverage this example of outdated technology can upgrade to Oracle Database 19c, which is an older version but still maintained. Alternatively, you can upgrade to Oracle Database 21c, which is the latest version, released in December 2020.






Microsoft SQLServer 2016 (CRM)




Mainstream support for Microsoft SQL Server 2016 is no longer available, while its extended support came to a halt in January 2018. The risks of maintaining an SQL server after the end of support are nearly the same for all versions. For instance, firewalls and antivirus products won't still match the vendor's hotfixes and security updates, meaning your systems will be vulnerable to hacking. Other risks include compliance, reputational, and high compatibility costs.



Database migration is an effective approach to prevent data leakage. Check the go-to guide. Legacy Database Migration: Effective Data Migration Plan 





Companies that rely on this technology can either purchase extended security updates for a temporary fix or upgrade to the latest versions of SQL Server. Options for the latter move include upgrading to Microsoft SQL Server 2017, released in 2017.





This updated version adds Linux support for various Linux platforms, such as Docker Engine, Red Hat Enterprise Linux, and SUSE Linux Enterprise Server. Alternatively, you can migrate your on-premise Microsoft SQL workloads to Microsoft Azure Cloud. This option consolidates your environment for optimized performance, provisioning, and recovery. 














Microsoft Sharepoint Server 2010 (CRM)




Although Microsoft sells its Sharepoint server versions as document management and storage systems, these software technologies are highly configurable for custom uses in various organizations. Moreover, these products come in multiple editions that serve different functions. 





Microsoft Sharepoint Server 2010 features various changes, such as early social networking features, central administration rebuilding, and sandboxed solutions, as opposed to earlier versions. However, it became obsolete on April 13, 2021, when Microsoft stopped extended support for the system. Mainstream support stopped a little bit earlier in 2015.





Using this outdated software exposes your business to severe content security risks that can cost fines and brand reputation when regulated data is breached. To avoid this, you can upgrade to Microsoft Sharepoint Server 2013, or the latest versions of 2016 and 2019.






Hortonworks Data Platform (Open Source Framework)




Hortonworks Data Platform (HDP) is an enterprise-ready data platform that is security-rich and open-source Apache Hadoop distribution. It is based on a centralized architecture (YARN). HDP helps accelerate decision-making and innovation by powering real-time consumer applications and addressing the needs of data at rest in addition to delivering robust analytics. However, Hortonworks Data Platform has deprecated features and versions that simply need to be replaced in 2021.



Legacy systems of HDP are known to have vulnerabilities that can allow an attacker to save a malicious file on a host computer, and also expose sensitive information. Upgrading to new versions of HDP will help to mitigate these vulnerabilities.




MySQL 5.6 (Database)




After reaching its community end of life on February 5, 2021, MySQL 5.6 has joined the group of obsolete technologies with 9 years under its belt. This open-source relational database management system uses data relations to organize it into data tables, thereby helping to structure the data. Popular companies that reportedly use MySQL include Uber, Netflix, Shopify, and Amazon.



MySQL 5.6 is now known to have many vulnerabilities. Some of these include allowing an attacker to disable its functioning as well as exposing sensitive information.




.NET Core 2.1 (Programming language)




This framework is for building applications that are modern, internet-connected, and cloud-enabled. This can be used in Windows, Mac, and Linux to build a variety of web applications and services, mobile backends, and Internet of Things (IoT) apps. However, since August 21, 2021, .NET Core 2.1 no longer receives updates or technical support, and this includes security fixes too.





.NET Core has a laundry list of vulnerabilities that attackers may take advantage of. Some of these vulnerabilities do not even need an attacker to have special privileges! Some of the things that an attacker can do include running foreign code on a system, initiating a denial of service attack, exposing sensitive information, and executing code remotely.





It is advised to upgrade .NET Core 2.1 to 3.1 or a later version as they would be more secure and have important updates and technical support. Alternatively, you can switch to ASP.NET Core, a Microsoft successor to ASP.NET, used by various companies like Alibaba, Queue-it, and LiteTube.





Learn the best practices on upgrading .NET Framework to .NET Core. How to Convert .NET Framework to .NET Core: Migration Guide 




Windows 7 SP1 (OS)




Microsoft’s official support for Windows 7 ended on 14 January 2020. Accordingly, PCs running Windows 7 after this date are no longer receiving security updates. Windows 7 proves to be a very vulnerable system, with information available on the web that offers to inform anyone how they can do such things as hacking a Windows 7 administrator and user password. However, Windows 7 still is in use at some companies and largely at government and education institutions.



In February 2021, there was an attempt to poison a Florida town’s water treatment plant by unknown hackers. It is widely believed that the attack may have involved hackers leveraging TeamViewer, a remote connectivity software, to target PCs that run Microsoft’s antiquated Windows 7 operating system. This potential tragedy was only stopped by the quick thinking of an employee. This was a really close call! The best solution is to migrate from any old operating system to a new and fully supported one.




AngularJS (Framework)




This web framework reached the end of life support at the end of 2021 meaning that users will no longer have the vulnerability protection that is so vital. IBM has highlighted a number of vulnerabilities of AngularJS which include an attacker being able to steal a victim's cookie-based authentication credentials and also cause a denial of service. Performance issues with AngularJS have also caused numerous downtimes. Most sites have already migrated to new Angular versions though there are still sites like Upwork.com and cricbuzz.com still using AngularJS. The good news is that AngularJS is one of our areas of expertise and we are the best at migrating AngularJS to Angular 9+.



Migrating AngularJS to Angular isn't an easy call. Read this guide Guide for Upgrading AngularJS to Angular with an Example of Real Case

Examples of Obsolete Technologies in 2022



There are technologies that were still in use in 2022, but in reality, their technology lifecycles had already ended. That means businesses using such technologies have to brace for incompatibility challenges in the near future or jeopardize their IT infrastructure security. Some of the obsolete technology examples in 2022 include:







Databases



Even if your database might still work exemplary well, it reaches a time when it becomes dead. Inasmuch as it can be tempting to run operations on outdated databases, the risks these poses are not worth it at all. 



For instance, the costs of maintaining the system may run overboard, not to mention difficulties in hiring talents that can attend to obsolete software. Moreover, obsolete software creates easily exploitable security loopholes and threatens data leakage. On the flip side, upgrading to the latest version of your database mitigates all these risks. 



Examples of obsolete databases in 2022 are:




IBM DB2 v11.1.x;



Red Hat Linux (RHEL) v8.2;



Mongo DB v4;



PostgreSQL 10.12; 



Oracle 12 on Windows. 




To ensure that you have a smooth migration process, it will help if you conduct a data audit to eliminate errors in data sets dependencies. It will also help if you secure your data using tools that can detect intrusion and give you up-to-date security analytics. 



 VIEW CASE STUDY  



CRMs



Outdated CRMs are a blow to productivity. Therefore, migrating to newer CRMs is essential to maintain an effective workflow. Otherwise, you'll be exposing your business to various risks associated with the use of obsolete CRMs, such as missing out on critical software updates and fixes. 



Apart from getting outdated and no longer receiving support, there are several other reasons a CRM can become obsolete. Examples of outdated CRMs in 2022 include: 




Peoplesoft CRM v9.2;



Microsoft SQLServer 2012;



Microsoft SQLServer 2017;



Microsoft Windows Server 2016. 




However, upgrading to the latest CRMs from a retired version can be pretty challenging, since this is not a simple plug-and-play tool that you just add to your IT infrastructure. That said, here are some practices that can help you transition smoothly:




Set up the required internal usage guidelines;



Have a dedicated super user to see the project through;



Work alongside a specialized project manager;



Onboard all executives to the plan.




Operating Systems



When an OS vendor discontinues support it is only a matter of time till some vulnerability is exploited and anyone using the system puts their whole network at risk. Since an OS manages a computer’s software resources, hardware, and its memory, and processes, it is vital to always use one that is up to date and is supported. 



These are some dangerously obsolete OS still in use today by some institutions like hospitals around the world.




Windows XP;



Windows Vista;



Windows 7.




Programming Languages



Even programming languages become obsolete as developers migrate to using newer languages. This results in fewer devs with the know-how of using these languages and a decline in the all-so-important community support. 



Here are some languages becoming obsolete:




NodeJS 1.2x, 1.7x, 10.x;



VB6, VB.NET;



ASP.NET MVC.




Components



As technology evolves, components also do in order to cater to the new and improved processes run by computers. This means older components become obsolete and cannot be used as parts of the new technologies. 



Using up-to-date components ensures your system runs effectively and seamlessly with your newer systems. IBM FileNet Application Engine is a good example of an obsolete component in 2022.



Frameworks



Old frameworks are vulnerabilities companies do not want to keep. However, migrating to newer, supported frameworks has never been easier with a reliable modernization partner, such as ModLogix by your side.



Below are some frameworks that have become obsolete and we are here to help you move on from them.




Windows Storage Server 2016;



.NET Framework 4.5.2, 4.6, and 4.6.2.

### Digital Transformation for Nonprofits: Approaches and Best Practices

Nonprofit organizations want to do more with less, just like businesses, and digital technology can significantly help. With digital technology, they can be more efficient, reach more people, and do better at their missions.



However, only a few nonprofit organizations are harnessing this opportunity. Despite 74% of nonprofits recognizing the importance of digital transformation, only 12% have yet to achieve digital maturity. This gap shows there's still much room for growth using technology. 



This article explores best practices and approaches nonprofit organizations can leverage to speed up their digital transformation. We’ll also offer valuable insights to ensure you achieve maximum impact with technology. 



Read on.



What is Nonprofit Digital Transformation?



Nonprofit digital transformation focuses on leveraging digital tools for nonprofits to enhance impact and service delivery rather than primarily boosting revenue. This can be achieved by adopting new software to streamline operations and increase efficiency, expanding outreach and engagement through social media platforms, and utilizing data analytics for informed decision-making. These digital strategies and nonprofit technology help organizations maximize their potential in serving their communities more effectively.



Benefits of Nonprofit Digital Transformation



Some key advantages of digital transformation for nonprofits include:



Data Security Enhancement



Nonprofits are not exempt from cyberattacks. In the last few months, 50% of NGOs, including the International Committee of the Red Cross, reported cyberattacks. However, with proper tools and digital measures, the chances of this happening again can be reduced. 



For example, robust encryption, access controls, and backup systems can safeguard data, ensuring confidentiality and protection from unauthorized access or breaches for data-driven nonprofits.



Cloud-Based Efficiency



Cloud technology can make a lot of difference to nonprofit organizations digital transformation. By leveraging secure cloud storage, these organizations can store and access data from any location, scaling their infrastructure as needed. 



This flexibility allows nonprofits to manage resources judiciously, reduce costs, and foster collaboration among team members, regardless of their geographic locations.



Optimized Processes, Higher Productivity



Digital tools help streamline operation processes in any organization, minimizing manual work and optimizing workflows for nonprofits. This automation boosts productivity, freeing up staff to focus on strategic activities. As a result, nonprofits utilize resources more efficiently, improving overall performance.



Streamlined Internal Communication



Powerful digital tools can enhance internal communication for nonprofits. From email and instant messaging to collaboration platforms like Slack and Trello, these tools facilitate real-time communication, promoting seamless coordination and collaboration among teams and stakeholders, fostering a more cohesive and responsive organizational culture, and reinforcing teamwork.



Mobile-Optimized Workplace



With 62% of employees reporting increased productivity when working remotely, operating away from the office is crucial for efficiency. 



Digital transformation can make this possible for nonprofits by providing mobile access to key systems, documents, and resources, allowing employees to work remotely. This flexibility ensures nonprofits can serve clients and stakeholders effectively, irrespective of location.



Data-Driven Decision-Making



Despite 90% of nonprofits collecting data, half still need to leverage it fully. Digital transformation can correct this, enabling organizations become data-driven nonprofits for informed decision-making. 



Data analytics tools allow nonprofits to analyze large datasets, identify trends, and make informed decisions aligning with their mission. This optimization helps target resources effectively and improve program outcomes.



Support for Capacity-Building



Digital transformation for nonprofits supports significant capacity-building opportunities. Online platforms, learning management systems, and e-learning tools grant access to educational resources and professional development opportunities. 



By investing in capacity building, nonprofits empower staff to adapt to changing circumstances and enhance their skills, ensuring sustained impact in their mission-driven work.



Challenges on the Way to Digital Transformation for Nonprofits



There are several technology challenges that hinder digital transformation for nonprofits. These obstacles often prevent organisations from fully embracing digital change:




Limited Budgets: Nonprofits often operate with tight budgets, and investing in modern nonprofit innovation can be a significant financial challenge. Acquiring new technologies, training staff, and implementing necessary changes require financial resources that may be limited.



Resistance to Change: Embracing digital transformation often involves a cultural shift within an organization. Resistance to change from staff, volunteers, or leadership can impede the adoption of new technologies and processes.



Lack of Expertise: Nonprofits may need more internal expertise to effectively plan and implement digital transformation initiatives. This can include a staff shortage with technical skills or experience managing complex technological changes.



Data Security Concerns: Nonprofits, like any other organization, handle sensitive donor information and must prioritize data security. Concerns about data breaches, privacy, and properly handling sensitive information can slow the adoption of new technologies.

### Guide to Building a Cloud-Based Architecture for Apps

Cloud computing has never been more popular. In fact, according to Gartner projections, cloud-native platforms are expected to make up more than 95% of new digital workloads by 2025, up from 30% in 2021.



It is, therefore, not surprising that building a cloud-based architecture for apps is becoming increasingly popular as more and more organizations look to leverage the cloud. If you are interested in knowing how to build cloud architecture for an application, you are on the right page.



This guide explores the key things to consider when designing a scalable cloud architecture. It also includes tips and best practices, selecting the right tools and services, and ensuring compliance. If you are a developer, architect, or IT professional, you will find this guide valuable for building cloud-based apps successfully.



What is Cloud Architecture?



A cloud-based application architecture is a design framework where applications are built, deployed, and managed using cloud infrastructure and services. Instead of relying on local servers or hardware, it leverages scalable, on-demand resources provided by cloud platforms like AWS, Azure, Oracle or Google Cloud. 



This architecture supports high availability, elasticity, and rapid development, making it ideal for modern digital applications that require global access, continuous delivery, and integration with services like storage, analytics, APIs, and AI.



Cloud-based application architecture offers several benefits for modern app development, including:




Scalability: Cloud architecture can be scaled up or down as needed, allowing apps to handle increased traffic and growth without significant infrastructure investments.





Flexibility: Cloud-based infrastructure can be accessed from anywhere and on any device.





Cost-effectiveness: Cloud providers offer pay-as-you-go pricing models, meaning you don't need to raise huge sums for investments in hardware and infrastructure.





High availability: Cloud providers offer built-in redundancy and disaster recovery features, ensuring that apps are always available to users.





Security: Cloud providers make significant investments in security infrastructure and best practices, which help protect user data from cyber threats.




With these benefits, application cloud architecture allows for faster and more efficient cloud system design and development. 















The primary components of cloud architecture are:




Client Infrastructure



Application



Service



Runtime Cloud



Storage



Infrastructure



Management



Security



Internet




These components work together to provide a flexible, scalable, and cost-effective way for developing a cloud architecture for an application.



How to develop an effective cloud migration strategy? Read the practical advice in our blog post Guide to Cloud Migration Strategy Process 



Cloud architecture is massively different from on-premise architecture, which is limited by location and device dependency, performance and capacity constraints, vulnerability to manmade and natural disasters, and maintenance challenges. No wonder Gartner estimates that global spending on the cloud could reach almost $600 billion by the end of 2023. 



Cloud vs. On-Premise Architecture: What’s Right for Today's Businesses Needs?



Choosing between cloud and on-premise infrastructure is a key decision for any organization undergoing digital transformation. While on-premise still serves niche needs, the cloud has become the preferred approach for most modern enterprises.



Cloud architecture offers speed, flexibility, and scalability that on-premise setups can’t match. It enables businesses to:




Launch faster with lower upfront investment



Scale instantly based on demand



Reduce maintenance and IT overhead



Enable remote teams and global collaboration



Access AI/ML, analytics, and advanced services natively




When On-Premise Still Makes Sense



On-premise may be required for:




Regulated industries with strict data control needs



Other legacy systems compatibility



Custom hardware setups 




However, it comes with high upfront costs, limited scalability, and a heavier operational burden.



Top 6 Tips to Build Cloud Architecture



When it comes to cloud-based architecture development, there are a few key considerations to keep in mind, especially in terms of design, performance, scalability, and security. Here are six tips to help you get the best result:



1. Clearly define your requirements and goals



Before you even begin to develop apps cloud architecture, it's important to take the time to clearly define your goals. 



What are you trying to achieve? Remember, this should focus more on the business value of your product. When you can identify the solutions your product will deliver, you will be able to choose the right technology for your purposes.



To deliver business value, your product should target two areas:





Hard cost savings: This means the cost-effectiveness of your application. Will it deliver cheaper storage or cost-effective computing?





Soft cost savings: These are the intangible benefits of your product. Admittedly, they are difficult to quantify, but focusing on business values means that your app should be able to deliver some form of competitive edge.

Answering these questions upfront will make the design process much smoother, make it easy to milestone your progress, and help you track metrics.



2. Use a service-oriented or microservices architecture



One of the best ways to take advantage of the cloud is to use microservices in cloud. This approach allows you to build apps with cloud architecture and deploy individual services independently. On the other hand, single unified designs lead to lengthy development cycles and require significant testing needs.



Why choose microservices? Learn the advantages and disadvantages of microservices here. Microservices Architecture Advantages and Disadvantages, Risks, and 5 Use Cases 



It also gives you the ability to scale services independently. This means that you can scale only the resources you need, and prevent bottlenecks in the system. 



3. Use Continuous Integration and Continuous Deployment (CI/CD) best practices



CI/CD helps to automate the process of building, testing and deploying code changes. This can be a huge help when it comes to deploying cloud-native applications, as it can help to ensure that code changes are tested and deployed quickly and efficiently. CI/CD cloud deployment can help reduce downtime and improve overall reliability.



4. Consider serverless architecture for certain parts of your application



One of the emerging trends in cloud application design is serverless architecture. This approach can be a great option for certain parts of your application, such as event-driven workloads or infrequently used functions. 



Some of the benefits of strategically using serverless are:




Serverless computing has the potential to minimize your overall cloud cost, as you don’t have to pay for idle resources.



It enables applications to swiftly scale up and down regardless of data centers.



It decreases the amount of time and effort necessary for developers to install and manage apps. They do not need to set up a whole server to host the application.




5. Include security in your design



Security is a critical concern for any application, but it’s especially important for the cloud and should be a top consideration when creating cloud-aware application architecture. It should be integrated into your cloud-based application architecture from the get-go, as part of the application design.



This includes securing data in transit and at rest, implementing cloud access controls and authentication, and monitoring for potential security threats.



6. Allow plenty of time for testing



You need to allocate adequate time and resources for testing so you can be confident that your design will scale and perform as expected. This includes testing for performance, scalability, and cloud architecture security, as well as user acceptance testing to ensure that the application meets the needs of your users. 



Remember, testing should be done not just at the end of the project, but throughout. This is the best way to avoid experiencing problems down the road.

Best Practices in Cloud System Design



Netflix, Spotify, Salesforce, Dropbox, Uber, and Airbnb are some of the most popular applications and platforms based on cloud architecture. These products are successful because they followed a checklist of best practices before, during, and after development. Netflix alone made a whopping $31.4 billion in 2022 after improving the cloud infrastructure design.  



Any business or organization looking to develop and deploy cloud-based applications needs to be aware of certain best practices to ensure a successful outcome. Some of the important ones are.















Design for failure



When you're building a cloud architecture for an app, it's important to design for failure. This means that you need to anticipate that things will go wrong and create a fault-tolerant cloud architecture design that can handle those failures. By doing this, you can ensure that your application will be able to continue running even if something does go wrong.



Implement a multicloud strategy



Another important thing to keep in mind when developing cloud-based architecture for an app is that you should not put all your eggs in one basket. Instead, you should implement a multicloud strategy to minimize your risk and take advantage of the different features and capabilities of each cloud provider. Google Cloud, AWS, Microsoft Azure are vendors you can use for your multi-cloud strategy.



Design for automation



The cloud allows for dynamic and high scalability system design, therefore, you should create your architecture in a way that makes it easy to automatically provision and manage your servers and cloud application components. This will allow you to quickly and easily scale your architecture as your needs change.



Decouple your components



When you're designing, it's important to decouple your components. This means that each component should be able to function independently of the others. By doing this, you will make your application scalable and easier to maintain.



Design components to be stateless whenever possible



When you create a cloud architecture for an app, you must be deliberate about how and when you store state. By making your components stateless, you can avoid having to store sensitive data in the cloud. Designing your component stateless also makes it easy to scale, repair, rollback, and load-balance components.



Plan for security and compliance



Finally, security should always be a top priority when you build cloud architecture. You need to make sure that you develop a secure cloud architecture, and that your system meets all relevant compliance regulations.



What about on-premises to cloud migration?



There is no one-size-fits-all answer to the question how to create a high scalability architecture, however, some general tips that can help make the transition smoother include:




Defining the goals and objectives of the migration.



Assessing the current state of the on-premise infrastructure and identifying which components can be migrated to the cloud.



Developing a clear plan for the migration, including timeline, budget, and resource allocation.



Testing the migration plan thoroughly before executing it.



Monitoring the progress of the migration and making necessary adjustments along the way.



Post-migration, reviewing the results and fine-tuning the process for future migrations.

Deployed in 2009 as a custom solution for Alibaba’s eCommerce platform, Alibaba Cloud is among the fastest-growing services in China and Southeast Asia. Its products and services include Analytics and Data Technology, Database Services, Storage and CND, Elastic Computing, and Apsara Stack. The service covers 19 regions and over 56 availability zones globally.



Here are the benefits of migrating: 



Optimized operating costs 



Overcoming on-premise to cloud migration issues can be a pivot for business success with greater cost-saving advantages to optimize operating costs. A recent survey by Microsoft Office 365 reveals that 86% of small businesses report reduced operating costs after shifting to on-demand computing. 



A majority of public services offer a “pay as you go” pricing model, meaning you only incur the costs of consumed resources that allows you to optimize cloud migration costs. You also don’t need to foot maintenance bills for IT assets that you use occasionally. It gets better — a typical upfront investment for a data center gives you ongoing 24/7 technical support and maintenance to compete favorably in the modern business landscape. 





Greater flexibility and ability to scale 



As noted earlier, businesses that embrace on-demand computing pay for the resources they only consume. This level of flexibility means that an organization can alter its resources instantly on demand whenever there is a need for powerful computing resources. On top of that, organizations that prevail over cloud data migration challenges can adapt quickly to shifting consumer needs without having to worry about a contract, minimum term, or rigid IT strategy. 





Improved security 



Another benefit of overcoming cloud migration challenges and setting up your IT infrastructure in an on-demand computing environment is improved security. Cloud services allow enterprises to store data centrally for greater protection and visibility. This is made possible through advanced in-built security features and automatic updates. Additionally, service providers also take the responsibility of shielding your business systems and applications from unwanted traffic outside a given scope. 





Industry compliance 



Cloud computing platforms offer services that meet specific industry compliance requirements, making the migration ideal for highly scrutinized sectors like banking and finance, healthcare, or government. 



For instance, Azure’s Office 365 productivity platform has auditing capabilities for files and Power BI activities, allowing users and regulators to see how data is accessed and used. Similarly, the AWS cloud has various compliance certification levels, including HIPAA, ISO27001, and AICPA/SOC. 



Backup and recovery 



Experts believe data loss can cost an organization anywhere between a few thousand dollars and $15 million. Businesses that overcome the challenges faced during cloud migration enjoy in-built data backup and recovery features that are handy in the event of a primary data failure. This ensures business continuity, protects reputation and mitigates insurmountable recovery costs in the event of a ransomware attack.



Even with clear benefits, migration to the cloud challenges many organizations due to complexity, data security concerns, and integration issues. Let's explore them in depth.



10 Challenges of Migrating to the Cloud and Their Solutions 



Now that you understand the benefits of cloud computing, what are the cloud data migration challenges, and how can you prevail over them? Well, inasmuch as change can be hard and many people tend to resist it at first, technical challenges in cloud migration shouldn’t hold your business back from attaining its full potential. 















That said, here are 10 prevalent cloud migration problems and how to solve them:



1. Data Security Risks in Cloud Migration



Data safety and compliance risks are still among organizations' top cloud migration security challenges. These risks can emanate from data breaches during the migration or weak access control over sensitive enterprise data. 



Solution 



While cloud services are inherently secure, it will help if you pass your data through a secure path inside the firewall when migrating to the cloud. You can add an extra layer of assurance to your cloud data protection strategy by encrypting the data and ensuring that your strategy follows industry compliance standards.



2. Cloud Migration Process Difficulties and Their Uncertain Cost



Although a successful cloud migration can cut IT operating costs in the long haul, the biggest challenge arises when estimating the actual upfront investment. This cost can shoot up the roof when other indirect project expenses come into play. This includes costs for transforming the organization for cloud computing, as well as the expenses of vacated data center capacity. 



Solution



You can prevail over this uncertainty by planning carefully with your service providers and factoring in the hidden costs of migration in the budget. Overall, you are looking at the following cloud migration costs: 



Pre-migration 




Consultations 



On-premise data management 



Database upgrade 




Migration 




The project itself



Refactoring 



Application and code changes 




Post-migration




Monthly or yearly license 



System maintenance 




3. Legacy Architecture Constraints



Legacy systems are often built on rigid, outdated architectures such as monolithic applications, mainframe-based platforms, or tightly coupled client-server models — that weren’t designed for modern cloud environments. This architectural inflexibility poses major obstacles during migration, as these systems typically lack scalability, modularity, and API readiness. 



Solution



As a result, significant reengineering or replatforming is often required just to enable basic cloud compatibility.



Organizations should begin with a comprehensive assessment of their legacy architecture. Choosing the right modernization path: containerizing specific services, transitioning to microservices, or incrementally replatforming key components. 



4. Wrong Cloud Migration Strategy 



You may encounter various cloud migration challenges if your team doesn’t deliberate on a well-hatched plan. Many get it wrong — that planning is all about anticipating migration bottlenecks and creating remediation contingencies, forgetting to focus on understanding the current infrastructure and target cloud. 



Solution



With that in mind, you would want to devise a well-thought strategy that covers all intricate approaches to successful migration, such as app modernization and platform refactoring. This means conducting a thorough assessment of the current infrastructure, pain points, and making adjustments whenever possible for optimized performance in the cloud.



5. No Internal Capacity to Perform the Cloud Migration–Skill Gap



Switching to a cloud computing environment means deployment of new technologies, processes, or third-party integrations. In most cases, your current employees may lack the necessary skills and qualifications needed to fulfill IT roles under the new infrastructure and simply don’t fail the process. 



Solution



You can overcome this barrier by hiring an experienced cloud migration company to assist with the process and upskill your team. The experts will figure out the right strategy that complements a smooth transition process with everyone on board. Alternatively, you can hire fresh talents to fill the new IT positions.



6. Migration Complexities



Your organization can experience a cloud migration challenge if you underestimate the complexity of the project. For example, some organizations think they can just port legacy software to the cloud as it is. This can lead to a serious downtime and loss of key functionalities, which translates to unhappy customers, failures, and lost productivity.



Solution



To overcome this challenge you need clearly assess your current infrastructure to identify any compatibility issues or dependencies that could impact your migration, create a roadmap that outlines the migration process, and choose the right cloud provider that can meet your specific business needs. 



7. Low Application Performance After Migration 



One of the most overlooked post-cloud migration problems is low performance after migration. Legacy systems often feature several components hosted on multiple servers which lowers their flexibility when migrated to the cloud. At the same time, on-demand computing solutions come with varying storage options and services – it's elementary for legacy systems to face performance issues.  



Solution 



Application performance challenges can be addressed through cloud capacity planning. This process analyzes and measures the performance of your applications against predictive demand. With this approach, your team can then provision and allot the right resources needed to meet that specific demand.



8. Network Bandwidth 



You can also experience database migration to cloud challenges if you don't specifically define the network bandwidth requirements of cloud-powered applications. Typically, these applications should match or exceed the performance of on-premise deployments. Unless you define the bandwidth requirements accurately, the migrated applications will experience latency, resulting in poor user experience and unmet business requirements. 



Solution



You can solve this problem by factoring in network constraints before migration, with the help of network technology modeling tools. This will help you evaluate current application performance to determine areas that need improvement before the migration process.



9. Cloud Environment Adoption Resistance 



Employees may feel that cloud adoption will reduce their control over data and processes, leading them to resist the change. Resistance toward change is common, and switching to a cloud computing environment means more change and disruption around processes, systems, or leadership. 



Solution



Train your employees on the new cloud environment and the tools and processes that will be used. To ensure that everyone is okay and ready for the new IT strategy, develop a change management plan and implement it before, during, and after the migration. Also, involve them in the cloud adoption process and address their concerns. This supposed to smooth out difficulties.  



10. Legacy Systems Compatibility



Older systems were typically designed for on-premise environments and may not easily adapt to modern cloud infrastructure. Compatibility problems can arise with software dependencies, outdated technologies, and custom-built applications that don’t fit neatly into cloud architectures.



Solution 



To minimize these risks and start the cloud infrastructure migration, apply careful planning, accurate software estimation, potential re-engineering of legacy components, or consider using hybrid solutions to ensure that legacy systems operate effectively in a cloud environment. Simply put, monitor outdated elements closely and address them appropriately.



The Big Role of Data Governance Implementation in Cloud Migration



Data governance plays a crucial role in cloud migration by ensuring that data is managed, secured, and used effectively throughout the transition process. Implementing robust data governance frameworks helps organizations maintain data quality, consistency, and compliance with regulatory requirements.



To implement data governance strategy for cloud data migration you need data consistency and quality, regulatory compliance, security and privacy, data cataloging, and data lifecycle management.



By implementing data governance, organizations can mitigate risks associated with data breaches, loss, or corruption, and ensure that their data remains a valuable and secure asset in the cloud environment. And what's more important in helps overcome cloud data migration challenges.

### 5 Examples of Legacy Systems: Where and Why Ones are Still in Use

Even though there are many worrying examples of threats from legacy technology, a surprising number of companies continue to rely on legacy software.



Legacy software systems are still in use today because they tend to be reliable and familiar for most of their users. However, the risks inherent in aging solutions often result in big losses.



In this blog post, we will tell about businesses that don’t mind using legacy systems and discuss what prevents them from business modernization.



What are Legacy Software Systems? Definition & Overview



Legacy software systems are outdated computing systems, applications, or programs that are still in use and often critical to an organization’s operations. 



These systems may no longer be supported by their original developers, may lack compatibility with modern tools, or may pose integration and security challenges.



Types of Legacy Systems



Legacy systems come in various types, and businesses use them for different reasons. Here are some characteristics of a legacy computer program that need modernizing:




End of Life (EOL): Systems that have reached their useful stage, resulting in vendors discontinuing the product, such as Microsoft's Windows 7.



No Updates Available: A system with no updates or new versions is a classic example of legacy software. This hinders innovation and forces businesses to shift to a new vendor and create new processes.



Unable to Scale: Software incapable of scaling to support new functions, rendering certain aspects obsolete or outdated. An example of legacy system is a set of large streams of data or increased financial transactions.



Outdated Architecture: Problems caused by legacy code architecture and data.




Who Still Uses Legacy Software Systems?



We’ve conducted profound research to find legacy system examples in government, banks, background checking systems, and business. Let’s take a look at them to see the negative consequences they can cause and learn the most effective approaches used for modernization.



Legacy System Examples in Government Organizations



A study conducted by Dell revealed that more than 70 percent of federal IT decision-makers in the USA, Germany, the UK, Japan, Brazil, India, and China use outdated software. Furthermore, half of the government representatives surveyed said that their legacy software has exceeded its end-of-life date. Curiously, COBOL is the most popular language among federal governments, even though it was initially developed almost 60 years ago. COBOL legacy systems continue to dominate many organizations, particularly in finance and banking.



Case 1











In 2017 a computer glitch at the Internal Revenue Service (IRS) had damaging results. The computer failure blocked the agency’s ability to process the electronically filed tax returns of nearly five million Americans. 





Lawmakers claim that the agency’s computer system has grown worse as a result of decreased investments in technology modernization over the last eight years, from about $14 billion to nearly $11 billion. During this period, the tax network has increased in complexity while the population of the USA has grown, which means that the number of people who file tax returns electronically has increased as well.



Source: United States Government Accountability Office Report







Case 2



The drastic rise in unemployment due to COVID-19 has revealed the US unemployment systems’ inability to handle a large number of cases.



Most states use unemployment systems that are over 40 years old and run on COBOL language. It’s no wonder that such outdated programs couldn’t process the requests of 13% of the US’s workforce that have been left without a job. The absence of COBOL programmers has only made the situation worse, as the US does not have enough professionals to maintain the old software. However, being one of the most vibrant legacy system examples, COBOL modernization takes costs as well.



The COVID-19 pandemic has also disclosed the vulnerability of many organizations that cannot support remote work. The outdated software they use doesn’t have enough capacity and isn’t flexible enough to quickly implement system changes.



Examples of Legacy Software in Banking Industry



Banking is among outdated technology examples as well. The Financial Times reports that a shortage of developers experienced in COBOL, the system that is driving most bank mainframes, will eventually force them to switch.



Case 3











The Royal Bank of Scotland (RBS) faced many IT issues caused by outdated technology, such as blocked account access and payment processing glitches.





The bank's ancient IT infrastructure was built before the mobile banking age, so the IBM mainframes used by RBS were “creaking under the strain of customer demand.”



Another Legacy System Example: Background Checking Systems



Just like banks, background checking systems suffer from increases in mobile traffic and diverse data sources. As a result, the system rarely performs at the needed level and crashes. The system is typically too complex to migrate easily to the newer technologies.



Case 4











Thanks to technology obsolescence, there was a massive intrusion into the U.S. National Background Investigations Bureau in 2015. To put it succinctly, the system was hacked. 





According to Vice News, the institution had already been working without any IT security staff for an astounding two years at the time it was compromised.



Legacy System Examples in Retail and Other Commercial Organizations



You will be surprised to learn that many retail, web, and manufacturing companies use legacy systems, even though businesses are expected to be up-to-date to survive in the market.



Case 5



In retail, corporations spend 58% of their IT budget on maintaining legacy systems. The main reason why businesses use legacy software is that the sales terminals use Intel 286 computers. Advanced computers are likely to run into problems while using old software. Another reason why software modernization is being delayed is the fear of cybersecurity issues. 



Look at these hidden costs of maintaining your legacy software. The Cost of Maintaining Legacy Systems: How Much You Overpay 



Although software modernization requires significant investments, it’s a necessary step for retail management technology to sync information properly. It is also needed so the business can spend the budget on improvements rather than on the maintenance of outdated systems. 



There is one common feature in each of the examples of old legacy systems mentioned above: All of them were using Oracle, Microsoft, or IBM software products. According to a Flexera report, these three IT service providers were among the top manufacturers of IT products with end-of-life and end-of-support status in 2018. As information technology pioneers, they have created many languages, environments, and operating systems, many of which have become outdated over the years. At the same time, these companies are the most significant innovators in technology development and they offer many options for migration. But if that's the case, why are there still companies that use outdated technologies like Visual Basic and DB2?

Why Companies Use Legacy Systems?



Research conducted by Avanade indicates that senior IT leaders believe the replacement of legacy software can potentially decrease operating costs by 13 percent per year and increase annual revenue by more than 14 percent.



Source: IT MODERNIZATION: CRITICAL TO DIGITAL TRANSFORMATION BY AVANADE







Even though most respondents (80 percent) believe that not modernizing IT systems will negatively impact the long-term growth of their organization, only one in three companies modernizes their software systems on time. Why are legacy systems still used?



Still can't decide on modernization? Read this article. Advantages and Disadvantages of Legacy Systems. What to Choose — to Maintain or to Modernize? 



There is a stereotype that says business is a rational field, just like a living being. At ModLogix, we believe every business has a human face — or several faces — that exerts influence on the company development vector and spreads their personal values, like Bill Gates at Microsoft or Steve Jobs at Apple. There are four main things preventing businesses from moving forward, and they're the same things that strongly impact human lives: fear and circumstances.  



The Fear of Uncertainty 



There's always a risk that a modernized system won’t meet the business's needs or that it will work even worse because of technological defects, and this risk often prevents legacy software owners from modernizing. At the same time, the wide variety of modernization options confuses businesspeople, who are searching for better results for a fair price.



Is it better to do software re-engineering, to re-build the app, re-platform, or apply cloud computing? It's a difficult question, and the answer will be different for each company. Partially changing the system can make it even more cumbersome, while changing it completely can destroy its business value. Even if the modernization is performed well and the new system works correctly, it's still necessary to retrain the staff who use it. Therefore, we understand why starting such a project could cause fear.



There Are Specific Requirements for Software 



Nearly 44 percent of Avanade's respondents say they lack a budget outside of the IT department for transformation. Do they have the money to replace the system? As a rule, modernization is the cheaper option, so if you lack the budget for that, you certainly don't have the money to develop an entirely new solution. However, simply having enough money to invest in the software system re-platforming doesn’t mean you will be able to pull it off.

In some cases, computers that are obsolete at first glance happen to cope the best. NASA’s computer hardware onboard the Orion runs on two IBM PowerPC 750X single-core processors. These dinosaur chips have been in use since 2002, and they are no faster than modern smartphones. But despite this, NASA uses them, and it's not because of budget constraints. The thing is, IBM computers are reliable, and that is the most crucial requirement in space.

In other cases, software systems can’t be modernized because of tech specifics, lack of tech documentation, or an inability to extract data in situations where data loss is unacceptable. Such circumstances cause complications, and engineers have to search for ways to fix the situation. Such searches take time and the results are hardly predictable, so companies prefer to use legacy software until something changes, for instance, the launch of a new development tool.





The Fear of Taking Operational Risks



Legacy software modernization is a timely process, and the fear that it will disrupt the business prevents many companies from going through with it. Contrary to popular belief, the modernization process cannot cause business disruption, as the old system can stay up and running while a team of experts works on the new and improved one. 



Some industries, such as healthcare, for example, cannot interrupt their work. However, according to a 2021 HIMSS survey, nearly 73 percent of healthcare providers continue to use legacy information systems., and the legacy medical data of 5 million Americans can be easily hacked online. Although the healthcare industry is seen as an industry where software modernization is difficult to implement, it should at least be done for security purposes. 



These case studies prove that software modernization is an effective measure. 3 Legacy Software Modernization Case Studies and 12 Lessons We’ve Learned 



After the modernization process is successfully completed, a company can face employees struggling with the new technology and requiring more time to perform regular tasks. Consequently, the company loses time and money because the team is considered inefficient during their learning period. According to McKinsey research, only 30 percent of companies succeed while trying to implement modernized technology, and the adaptability of employees to the new technology is an integral part of their success.

There’s a Custom Solution that Still Works



When businesses started to go digital 20 years ago, companies created custom technical solutions specifically for their tasks and business goals. Those systems are still in use because they perform the needed operations and seem to be more reliable and exclusive.



Today, legacy software does more harm than good, as it no longer serves its purpose and requires a significant budget for maintenance.







 VIEW CASE STUDY   







5 Main Risks of Keeping Legacy Software Systems



Legacy systems, while still functional, may be unreliable due to compatibility issues and a lack of support and maintenance. Below are five primary risks of legacy systems for organizations:




Security vulnerabilities: Legacy systems may have outdated security protocols and software, making them more susceptible to cyber-attacks and data breaches.



Lack of compatibility: Older software may not be compatible with newer hardware and software systems, leading to operational inefficiencies and a decreased ability to integrate with modern technology.



Limited support: Older software may no longer be supported by the vendor or manufacturer, leaving organizations without access to critical updates, patches, and technical support.



Increased costs: Maintaining legacy systems may require specialized skills and hardware that are difficult to find and expensive to maintain. Additionally, the longer an organization waits to replace legacy system components, the more costly and time-consuming the transition becomes.



Reduced productivity: Legacy systems can hinder an organization's ability to innovate and adapt to changing business needs, resulting in reduced productivity and competitiveness in the marketplace.




Benefits of Modernizing Legacy Systems



Cost Efficiency: Although modernization may involve upfront costs, it significantly reduces long-term expenses.



Better Integration with Up-to-date Technologies: Outdated software aren't designed to integrate easily with emerging technologies like cloud platforms, APIs, AI/ML tools, and data analytics solutions. Modernization provides any opportunities for integration.



Improved Performance & Scalability: Unlike legacy platforms that may struggle under increased workloads, modernized systems can adapt to user demand with ease, ensuring smooth operations and better system responsiveness.



Enhanced Security: Upgrading to modern platforms brings built-in security features, regular patches, and better encryption standards, which help safeguard sensitive data and meet evolving regulatory requirements.



There are also many other benefits organizations gain when moving away from unstable and severely outdated systems. However, it's equally important to carefully assess the risks and approach modernization with a well-thought-out strategy.

Conclusion 



Legacy systems are still used because employees and business owners prefer them. We tend to stick to what we know because it is familiar, and something new is often “scary.” So, there is a desire to keep the old IT systems where every button and every small issue is familiar and possible to deal with.



Another reason is that sometimes it is impossible to transfer all the data into a new system without losing some of it. Data is extremely important to some institutions, and they are not ready to deal with the data-loss. And finally, the programmers who can run the company’s legacy systems are simply not used to new kinds of software. They do not have enough skills to utilize new programs, so companies do not want to invest in the new system and education.



As we've seen in legacy system examples, there're many reasons to prevent companies from investing in modernization. However, all outdated systems must be renewed at some point, and business owners must think of creating an application modernization roadmap step-by-step.

### Legacy System Modernization Approaches: Practical Advice on Dealing with Outdated Software

The world is advancing quickly and what was once a perfect solution, quickly becomes outdated and useless. Have you already made the decision to modernize your legacy system but not sure about what legacy modernization approach to choose and how to avoid possible pitfalls? Then, this article is for you, as we are going to discuss the most effective legacy software modernization approaches, their benefits, and pitfalls. 



We are going to go through the definition of legacy system modernization and the benefits it can bring. We will also highlight the struggles that legacy system modernization can cause, what approach you should take to overcome them, and the implications of legacy software system modernization. 



What is Legacy System Modernization?



Legacy system modernization is a process of updating legacy software porting it to a modern programming language, software libraries, or protocols, because the use of an outdated technology may result in unnecessary risks.  



So why do businesses need legacy system modernization? First of all, legacy software requires a significant investment of resources for its maintenance.  



Secondly, finding qualified professionals to support the system is a hard task, as not many programmers these days work with outdated languages such as COBOL or FORTRAN.  



Thirdly, outdated software is hard to integrate with new systems due to its architecture, underlying technology, or design, and there’s the risk that it can crash at any time.  



So, if business goals have changed over time, the inflexibility of legacy software could make the implementation of any changes almost impossible, which becomes a significant barrier to business development and revenue growth. 



If the disadvantages of using outdated systems are so obvious, why do so many companies still rely on them and postpone modernization? Many companies use legacy applications for core business operations such as high-volume data processing or conducting day-to-day operations that are essential for the functionality of your organization. Changing some elements of these systems is a risky step as it can bring the whole business to a halt.  



The legacy software is very expensive to maintain, and companies that postpone legacy code modernization will eventually incur heavy technical debt. So, although modernization requires decent investments, any business that wants to stay competitive needs to consider starting the process as soon as possible. 







Why Do You Need Legacy System Modernization?



In order to better understand whether a business needs modernization of their legacy system, it’s important to know the old system’s negative influence on a company’s growth. So, let’s discuss the most common reasons for starting a modernization process now! 



Legacy Software Requires Big Investments for Its Maintenance 



It’s a known fact that legacy systems require an immense budget and is a lot of effort to maintain, therefore modernization is a necessity. For example, the Government Accountability Office public report has revealed that about $337 million is being spent on the maintenance of the federal government's 10 legacy systems annually. Due to the large codebase and complicated functionality of the legacy software, updating or changing something within the system requires more financial and time resources than modern software. Moreover, legacy systems often require hardware that is also not cheap.



Here's the list of hidden costs inside your legacy software. Check The Cost of Maintaining Legacy Systems: How Much You Overpay 



Shortage of Professionals That Can Support Legacy Systems 



After all, you may not find professionals at the right time — legacy systems require specific skills and expertise. Young developers are focused on new technology while most of the COBOL developers who’ve been working on the legacy systems are retiring. So, finding people with the needed qualification is very hard and expensive.



Legacy Systems Are Very Inflexible 



The inability of legacy systems to adapt to modern business requirements significantly slows down business growth. Companies lose business opportunities and struggle to respond to new challenges while competitors have progressed.  



Connections to third-party tools or services require lots of effort. API vendors are compatible with most programming languages and frameworks, but legacy systems do not belong to this majority as they are very unique. Therefore, one must develop custom APIs that are pricy and need more time for development. 



As mentioned at the beginning of the article, the world is developing fast and there are changes in the market every single day. Only the ones who are quick to respond to the legacy system modernization challenge have an opportunity to stay on track and prosper. 



Legacy Software Is Vulnerable to Cyber-Attacks 



The question of cybersecurity is a delicate one when it comes to legacy systems. They have been there for years and attackers know for sure what harmful programs or malware can destroy it. In 2018 US Computer Emergency Readiness Team (CERT), on behalf of the National Cybersecurity and Communications Integration Center (NCCIC) have released an alert warning about the increased hackers' interest in legacy Enterprise Resource Planning (ERP) solutions. The outdated ERP systems have legacy system security risks and gaps that have allowed deeper access into the software's network. 



Who still uses legacy systems in 2022? Find here 5 Examples of Legacy Systems: Where and Why Ones are Still in Use 



WannaCry ransomware attack back in May 2017 has revealed the vulnerability of outdated systems no longer supported by Microsoft. More than 300,000 machines operating on Windows XP, Windows 8, and Server 2003 have been affected in 150 countries because they lacked security updates. What more evidence do you need?



Legacy Systems Don't Comply with Modern Regulations 



Data protection regulations such as CCPA completely change how we store and use data by requiring more effort on the business side to protect it. Not only the government but users themselves want companies to use their data in a safe way.



Laws such as HIPAA for the healthcare sector and GLBA for the financial one have recently applied some changes concerning the process of using and storing people's data. So, businesses need to readjust their system in order to adhere to all the regulatory requirements.

Legacy System Modernization Approaches



Since we’ve discussed reasons for legacy modernization, let’s move towards modernization approaches. There are various legacy system modernization approaches that are designed to meet different needs and have unique characteristics. We’ve broken them down for you below. 



Encapsulation 



Encapsulation is the process of reusing the main components of the system and omitting the legacy code while connecting it to the new access layers via APIs.



This legacy software modernization approach provides a new interface to the old components in order to leverage the app’s functionality; however, encapsulation won’t solve the maintenance issues. So, if you want only to change the interface part, encapsulation in software would be a great choice that also minimizes costs and reduces risks.



Rehosting 



Rehosting ensures easy migration of the whole system to new hardware, cloud, or virtual environment. Although rehosting legacy systems are generally considered just a step in the app migration process, it helps resolve support issues regarding open systems like SQL-based x86 environment or the cloud.



Due to this approach's low risks, it's popular among large enterprises that want to improve the system's performance while not disturbing its workflow.



Replatforming  



Software replatforming allows you to migrate components of an application to a new platform with minimal changes in the code. You do not have to change core code or features, which is very attractive to those who do not want to modify “too much” or are worried that users will not be able to use the new system.  



However, little changes mean restricted benefits. You will only be able to adapt to the components that are running on a new system and others will be not able to stay up-to-date for the modern market.



Is replatforming that simple to implement? We uncovered the possible scenarios to use it in our guide. What Is Legacy System Replatforming and When to Consider It 



Refactoring 



Refactoring is the process of improving the internal component of an old system without changing its external environment. It’s a great choice to make modifications in the configuration, solve tech issues, and make the code more clear and maintainable.



Refactoring legacy software makes the system more flexible so it can easily adjust to the current circumstances. This approach is recommended for businesses that want to move from containers to microservices in order to avoid software failures.

Rearchitecting 



This system migration approach is about altering the application code's architecture and legacy IT infrastructure to resolve performance and scalability issues. It is a fairly complex process that requires advanced technical skills.



Rearchitecting provides diverse benefits, such as improving app functionality and simplifying the process of integrating new features in the future. However, this approach is quite risky, as it can change the logic of a business and the way the system works in general.

Rebuild 



Rebuilding is a huge undertaking, but it is the best custom solution that you can get. Basically, a new system is built from scratch according to the needs of a business. The legacy system components must be rewritten and new functionalities must be built. New coding techniques reduce the time of development, improve security, and create custom network protocols. For example, sometimes you must partially rebuild your system to migrate from .NET Framework to .NET Core, as the legacy components won't fit the new software.  



The approach is also known to be more high-risk, as it applies a lot of changes to the original system.  











You can learn more about modernization approaches and when each of them can be applied here.

Industries That Are Actively Adopt Legacy Software Modernization: Business Cases 



Even though it's pretty complicated to undergo legacy system upgrade, many companies have chosen to pursue it. In some industries, it’s now more of a necessity.  



Healthcare



Cerner (now Oracle Health), provider of health information technology platforms and services, began a multi-year cloud migration effort in 2021, shifting legacy systems to Amazon Web Services (AWS) by 2023. This move helped hospitals reduce data silos and improve patient record accessibility, enabling better outcomes and more efficient care delivery.



In 2022, Epic, one of the largest providers of health information technology, announced updates to its legacy electronic health record (EHR) systems, introducing new FHIR-based APIs and embracing cloud-friendly architectures. This modernization allowed easier integration with telehealth platforms and population health tools, enhancing healthcare providers’ efficiency and patient engagement.



Manufacturing



General Electric (GE) modernized its legacy industrial software through the Predix platform between 2020 and 2022. By integrating IoT data and analytics, the company reduced equipment downtime and improved production line performance.



In 2021, Siemens, a global technology company, launched enhancements to its digital twin technology, enabling older manufacturing systems to integrate with cutting-edge simulation and IoT platforms. This effort allowed manufacturers to model complex operations, improve efficiency, and adapt quickly to market changes.



Telecom



Starting in 2022, Verizon, an American telecommunications company, transitioned significant portions of its legacy telecom systems to a cloud-native core, completing the effort by 2024. This modernization enhanced scalability and supported faster deployment of 5G and edge computing services.



Between 2021 and 2023, AT&T - an American multinational telecommunications holding company, retired many proprietary systems and adopted open-source and software-defined networking (SDN) technologies. This enabled cost savings and faster implementation of advanced network features, such as network slicing and virtualized RAN.



Transportation



Delta Air Lines, Inc., a major airline in the United States, began replacing parts of its legacy reservation and scheduling platforms in 2020, completing the upgrades by 2022. The modernized system allowed for real-time booking updates, improved disruption management, and a smoother passenger experience.



In 2021, UPS, a package delivery company, enhanced its legacy ORION routing system with AI-driven tools, enabling better delivery route optimization. This reduced fuel consumption, improved delivery times, and decreased overall logistics costs.

From the dominance of the .NET Framework to the game-changing rise of .NET Core and today’s unified .NET platform, Microsoft has made it a high-performance powerhouse driving the future of software.



But what do all these versions mean for developers? How did .NET evolve, what’s changed over the years, and which version should you use today?



This guide will explore every significant .NET release, key features across versions, and where Microsoft is taking .NET next. Let’s dive in!



What is .NET?



.NET is Microsoft’s all-in-one development platform, designed to build high-performance applications across web, desktop, mobile, cloud, and IoT environments. First introduced in the early 2000s as .NET Framework, it initially focused on Windows-based applications. However, as software development evolved, Microsoft expanded .NET into .NET Core, making it cross-platform, modular, and cloud-friendly.



Today, .NET has fully transitioned into a unified platform called .NET (starting with .NET 5). It combines the best .NET Framework and .NET Core, offering faster performance, better scalability, and full cross-platform support. 



.NET Versions Explained: Features and Differences



.NET has undergone multiple iterations, introducing new functionalities, performance improvements, and expanded cross-platform support. Over time, it has evolved into the following key categories:




.NET Framework – The original, Windows-only implementation of .NET, widely used for enterprise and desktop applications. It remains supported but is no longer actively developed beyond security updates.



.NET Core – A cross-platform, open-source framework introduced to provide a modular and high-performance alternative to .NET Framework. .NET Core 2.1 and .NET Core 3.1 reached end-of-life, but .NET Core as branding was discontinued when it was merged into .NET 5.



Modern .NET – A unified platform that started with .NET 5, merging .NET Core while incorporating some legacy .NET Framework capabilities. It continues to evolve, with the .NET 8 version being the latest.



.NET Standard – A formal specification defining a common API set for .NET implementations. It was widely used to ensure compatibility across the .NET Framework and .NET Core.

.NET Standard: The Glue That Held .NET Together



Before Modern .NET unified everything, Microsoft faced a challenge: .NET Framework, .NET Core, and Xamarin had different APIs, making code sharing difficult. A library that worked on .NET Framework wouldn’t necessarily function on .NET Core, and Xamarin introduced its own complexities.



To solve this, Microsoft introduced .NET Standard — a set of API specifications that ensured compatibility across different .NET implementations. Rather than being a separate runtime, the .NET Standard was a universal contract, defining a common set of APIs that all compliant .NET platforms would support.



Here’s how its versions evolved:



VersionRelease YearWhat It Brought to the Table.NET Standard 1.x2016The first attempt at unifying APIs across .NET Framework, .NET Core, and Xamarin, but the early versions had minimal API coverage — meaning many essential .NET Framework features were missing..NET Standard 2.02017The real turning point was that it supported thousands of .NET Framework APIs, making it much easier for developers to migrate code between .NET Framework and .NET Core. This became the most widely adopted version for libraries..NET Standard 2.12019The final version of .NET Standard adds even more APIs, including Span<T> for high-performance memory management. However, the .NET Framework was left out—it only worked with .NET Core 3.x and later, signaling the beginning of the end for .NET Framework compatibility.

### Visual FoxPro to .NET Migration Guide

To keep up with changes in business technology, many companies are considering processes to convert Visual FoxPro to .NET. This type of data set and workflow migration has to do with how database and data storage systems have evolved within the last couple of decades, and how businesses can profit from newer technology.



Visual FoxPro and Its Legacy



Ever since its origin in the 1980s, Visual FoxPro has been popular for Windows-based object oriented programming. This relational database management system was developed by Microsoft, and offers businesses a way to use development tools for efficient and versatile database design. Its handling of complex queries, good interface and brand-name recognition made Visual FoxPro a common part of the technology stack for enterprise, up until quite recently.



However, Microsoft ended official support as of 2015, and one of the best candidates for migration is .NET. So companies are trying to figure out how to upgrade their data sets and store them in new ways.



Why Migrate from Visual FoxPro to .NET?



Aside from the obvious lack of continuing support from Microsoft, businesses can get other additional benefits from efforts to convert Visual FoxPro to .NET.



Visual FoxPro migration services to .NET can better set up companies for scaling and Improved cybersecurity outcomes. There’s also compatibility and interoperability to consider. 



Also, as part of the cloud revolution, .NET is better set up to work with cloud gateways, and other aspects of the cloud premise – that data and workflows are moving from an internal network system to the cloud. 



In other words, because of the popularity of cloud environments and the sea change that led businesses to adapt, Visual FoxPro conversion is often a part of that overall process.



Other benefits of migrating from Visual FoxPro to .NET relate to better support of object oriented, programming languages, and scripts, as well as interoperability with Microsoft SQL Server. Many projects focus on porting to SQL server in the most effective ways. Having a better connection to the overall ecosystem is paramount.





These changes can lead to better enhanced applications and better performance. The best plan helps, rather than hindering business operations. A good migration can lower costs of process ownership and improve security.





When you can better match a system to modern distributed architecture, and frameworks like Angular and React, this is great for the modern engineering that companies need to do on enhanced workflow processes.





Challenges in Migrating Visual FoxPro Applications to .NET



What difficulties do organizations and engineers typically experience when trying to migrate Visual FoxPro?



Well, aside from labor-intensive processes of migrating the data itself, there are some hurdles to deal with in successfully changing over the legacy technology into something new.



Navigating two technologies 



the talent involved has to be cognizant in both technologies, and both technologies are different. VFP is a procedural language made for desktop database applications in the 1980s, whereas .NET represents more of a fundamental object oriented programming design.



Code rewriting or code refactoring 



This process can take a lot of time and effort. The coding time has to be built into the overall plan. 



Compatibility issues 



VFP has its own file format, and engineering teams will typically have to change the database schema itself in migrating to .NET. Whether it’s keeping massive amounts of data in an orderly form, or handling different data types, these can be challenging parts of the process.



Multi-channel operations 



Stakeholders also have to anticipate that they’ll be working on more than one channel in terms of overall business migration. Suppose that the company has a mobile element in addition to desktop applications. One may be easier to migrate than the other, and redesigning each user interface will add to the complexity of the migration process.



There are also challenges that often come at the beginning of a project:



Documenting the existing system 



Engineers will have to look at high-level metrics that show what’s needed. Engineers might be wanting to simply use SQL server to store data, or do additional things like converting data environments, or increase functionality for certain tools. Teams may want to figure out whether running .NET forms as objects will optimize a workflow process. In general, they have to assess the various conversion functions that are necessary and relevant, and think about how each of those will be completed, according to how the legacy system is set up, and what the road map for completion looks like.



Database upsizing 



Teams can consider SQL pass through or remote views strategies. They’ll have to understand any dependencies, and also possibly plan for parallel operations. These types of logistics should be front and center on any Visual FoxPro to .NET conversion plan.



All of these ideas factor into an overall conversion plan. 



Estimating Time, Cost and Resources



In figuring out how much time it will take to migrate Visual FoxPro and what it will cost, businesses have to understand many different factors.



For one thing, there’s the resource allocation involved – how much data will need to be handled, and what processes will the company need to implement? Then there’s the type of transformation and migration that will occur – is it something like ETL or ELT, or is it something else?



Pay scales and schedules and everything else also go into the mix, as any seasoned payroll manager will tell you.



Step-by-Step Guide to Convert FoxPro to .NET



Here’s a basic step-by-step guide to getting this process done.



Step 1: Planning



companies will have to make an inventory of everything that needs migration, and look at the actual workflows for these processes. They’ll have to figure out the scope of the project itself, and what is the highest priority for the business, and then they’ll have to put that team together and give them the tools to do the job right.



Step Two: Analysis



Companies will also have to be analyzing the existing VFP systems, looking at the code and the data, and getting a game plan together to change it. Documentation is important here, too. 



Step Three: Choosing the Right .Net Technology Stack



In a successful conversion plan, it’s important to be designing the destinations for data and workflows. It helps to look at the above tools mentioned in building a .Net ecosystem, and doing deliberate research on what to include. 



Step Four: Database Migration



This is where the actual transport and work will take place. There’s significant work involved in this process, which needs to be made into various sub-steps, tasks and business processes according to factors like the enterprise infrastructure or fabric. After identifying business logic, and rebuilding the interface, engineers will need to implement the data access layer, which might involve using Entity Framework Core, ADO.NET, or Dapper. They’ll need to migrate queries, with an eye toward SQL best practices.



Step Five: Testing, Maintenance and Implementation



Then there’s testing and implementation in a production environment, and companies will need to be engaged in different kinds of testing long-term, for example, user acceptance testing, and evaluating the rollout to see how well it actually works in practice.



Tools for Visual FoxPro to .NET Migration



As for tools for these kinds of practical migrations, organizations can use code converters and syntax handling applications to craft new environments in .NET for VFP processes.



They can use specialized SQL server tools, and languages like XSharp that were meant to complement Visual FoxPro. They can use Microsoft Visual Studio, which is a vibrant ecosystem for all kinds of creations within Microsoft’s Windows based environment.

These are important upgrades for a business, and they need to be handled correctly to support future success.

### 10 Questions to Validate Your Application Modernization Vendor Before Starting the Cloud Migration Process

Before starting working with someone and giving them your trust, you should do thorough research to establish whether the company is worthy of your trust. Validation of a legacy provider with application modernization questions helps ensure that the vendor is legitimate and will maximize your profit instead of making you lose your shirt. A legacy vendor is someone who understands your needs and requirements and is capable of providing the necessary services. 



Why It’s Important to Validate Your Legacy Vendor



But why are we talking about it? Does the cloud migration process fail very often? Is conducting a thorough investigation and pinpointing the vendor’s strengths and weaknesses an ambitious task that will take up quite a lot of time and effort? Is it worth the trouble? Let’s take a look at the latest statistics about cloud migration:




The migration process to the cloud is a long and bumpy road: 73% of such projects take at least one year to accomplish;



The planning of the migration process is difficult, and the deadline assessment fails almost every time: 96% of businesses that went through the process exceeded their planned timeline and budget expectations;



Sometimes the migration process can be so complex that companies give up altogether: roughly 74% of businesses said they moved their software back on-premise when they realized they failed to achieve the expected results. 




Since the failure rates are so high, a reliable partner to accompany you through the process’s pitfalls and challenges is essential. A legacy IT vendor is someone who will help you decide which data to move and which to leave behind, integrate your legacy system into the cloud, as well as take up the entire process of migration, from planning to completion. Here is the list of application modernization questions to ask a legacy IT vendor during the interview for successful hiring.



Can You Perform a Proof of Concept?



The goal of the Proof of Concept (POC) is to test the application's functionality after the legacy modernization vendor migrates it to the cloud, effectively simulating cloud migration services. PoC should be significant enough to test the basic features and critical points of the system. AWS suggests starting with a small database, launching and removing instances, and putting the system under stress. 





Additionally, going through the PoC, you will learn more about the cloud, how it works, and what benefits it provides. Finally, during this phase, you will be able to assess whether you need to create various IAM groups categorized by business units or IT roles like admins or developers.





But how does one measure the quality? How does one determine whether the PoC phase was successful, and the migration process is ready to be launched? There are several attributes that demonstrate the quality of system performance:

Security ensures confidentiality, integrity, and availability;



Testability shows the ability to identify failure modes;



Modifiability entails the processes of system changes and how they are being executed;



Usability serves as an attribute that measures user experience and satisfaction with the application.

Does the Migration Process Imply System Enhancements?



This brings us to the question about the benefits of migration. 




Faster deployment. By migrating to the cloud, you eliminate processes like buying servers and installing operating systems, which shortens the deployment times and allows you to launch your apps quicker and more frequently. A good legacy vendor will take care of the server-side issues allowing you to concentrate on your business goals. 



Enhanced security. Although you will still need to protect sensitive information, cloud providers help you keep your data safe. They conduct automatic security updates to make sure your data is protected from common threats. Make sure your vendor has enough experience with your business area — healthcare, insurance, eCommerce, and so on — to apply best practices while protecting sensitive data.



Continuous monitoring. Cloud providers offer automatic monitoring and notifications when your system experiences issues or stops performing. 



Scalability. When you move to the cloud, you can scale up or down easier and quicker. Instead of paying for the features you no longer need, you can rapidly adjust to meet your current business goals and save money.



Accessibility. A vendor will help you move parts of your data or all of it to the cloud, making it accessible regardless of the physical machinery, which opens up new business growth opportunities.




Do You Conduct Risk Assessment?





Despite all the benefits of cloud computing, nothing comes without any risks. Among the most common risks of moving an application to the cloud are legal protection and ownership issues, untrustworthy machine instances, and human errors.





A lot of risks revolve around the disclosure of the client’s personal information and reputation damage. The task of a legacy modernization provider is to identify possible risks, take them into account and try to mitigate them. 





First of all, the vendor will identify every potential risk and categorize them based on their impact: business, organizational, and technical risks. Second, the legacy provider will conduct the risk assessment and divide them into different levels of severity: low, middle, and high. Based on this assessment, the actions will be established: low risks can be simply monitored, middle and high risks – mitigated, possibly eliminated, or transferred. 



If a vendor is not planning to perform a thorough risk analysis, it jeopardizes your company’s reputation, which is not a good sign. Here application modernization questions will clear things out.



Does Your Migration Process Include Refactoring?



Refactoring is one of the most common approaches when it comes to cloud migration. Most legacy application modernization providers offer refactoring as a way to proceed. It involves rebuilding the architecture of the application to fit the cloud computing environment. A legacy vendor will rewrite parts of the codebase to ensure better flexibility and take full advantage of the perks that come with cloud storage. At ModLogix, we provide the refactoring service to almost all cloud migration projects we work on, as it helps scale the system in the future.



Legacy code is a minefield. Learn how to optimize your code base with this guide. Legacy Code Refactoring: Tips, Steps, and Best Practices 



Your vendor should be experienced enough to be trusted to modify your code, test it, and avoid possible issues with functionality. In the long term, refactoring will pay off and provide the highest ROI of cloud migration. 





Refactoring will cut your expenses by providing scalability, make your app more adaptable to change by simplifying the process of adding new features as well as increase resilience of your application.





Although refactoring is more time-consuming, requires more skillful workers, and poses a risk to your code and configuration, when it’s done by a trustworthy vendor, it is the best approach. 





Do You Execute the Migration of Databases as a Part of Cloud Migration?



A report made by Gartner, one of the biggest firms in IT research, estimates that 75% of databases will be moved to the cloud by the year 2022. Although the benefits definitely outweigh the risks, it is a complicated part of cloud migration and poses many challenges, so many providers avoid this step.



Your legacy app modernization vendor should be knowledgeable and experienced enough to successfully execute the cloud migration of your database. A good vendor should aim for downtime reduction and protection of your data during the process of migration. 











ModLogix realizes the full value and the importance of database migration as it gives you access to a large pool of database management systems, offers scalability, and reduces costs. When migrating the WebForms platform from on-premises to Azure, we faced a problem with different time zones that caused a total mess with record making. Our engineers rewrote 140 procedures stored in the database and the source code to convert everything to EST time zone, and the system started making records correctly.

Do You Provide a Rollback Plan or Is It a One-Way Migration?



In case the migration goes unsuccessfully or unexpectedly, a rollback plan becomes very important. A good vendor should be able to perform a rollback in case you’ll need to abort the migration. Below are three basic strategies you should consider while migrating to the cloud:




Basic fallback. In this case, the system will lose all new transactions and go back to its original state. This strategy is quite rare due to its extreme approach.



Dual write. This is the most time-consuming approach that requires you to write transactions to both databases at the same time. Although the rollback is easy to do, it involves a lot of complex modifications to the application.



Fall forward. This strategy requires the creation of a replica of the original database which is synchronized with the new database. In case of a rollback, you stop writing to the new database and continue with the replica.




Did you know that a rollback plan is an integral part of the cloud migration strategy? Guide to Cloud Migration Strategy Process 



Can My Team Complete Some of the Migration Work Internally?



In other words, can you, as a vendor, cooperate with my team? Although many companies choose to delegate this task to a third-party company, some have their in-house department that can participate in cloud migration. 



ModLogix is a software development company that can assist you in the cloud migration process. We believe that we can help you significantly decrease costs by improving your infrastructure and moving your app to the cloud. We can work autonomously or together with your team to execute each step of a successful migration process:

Validation, where we assess security compliance, network, and storage;



Migration, where we conduct the process of migration;



Ongoing management and monitoring, where we continuously offer technical support and proactive monitoring.




How Will Cloud Change Management Be Handled?



Cloud change management differs from the on-premise one for many reasons. First of all, cloud environments are built for agility, which means that changes will occur faster due to autoscaling. Having components and licenses at your hand, the changes can be made quickly, within a couple of clicks. Cloud change management makes setting up new environments easier and rolling back changes quicker.





Second, change management in the cloud requires a mindset change — moving from control to enablement. Common bureaucratic processes that are usually involved in change management do not work in the cloud environment. Automation and transparency of the cloud ensure the safety of the changes and reduce their potential risks.





As long as the risk is within the set limits, the team should be able to execute the changes autonomously. In most cases, cloud migration execution is just the beginning of many improvements and adjustments. Thus, having a reliable vendor at your disposal ensures smooth and seamless change management and increases the chances of a coherent transition.

Do You Provide a Cost Analysis for Cloud-Hosted Solution Compared to On-Premise Solution?



According to a survey conducted by Gartner, one of the most frequently asked questions by cloud migration is whether the cloud is really cheaper than on-premise. 











The cost analysis estimate is very difficult to conduct as it depends on the system’s specifics, number of servers, server’s costs, and many more. Sometimes, going serverless is actually more expensive for a company than staying on-premise. However, it is not impossible to calculate the difference when provided with all the essential information. Greg Deckler, the Vice President at Fusion Alliance, has conducted his own estimated analysis and posted it on LinkedIn. 



A trustworthy vendor will provide you with a comprehensive analysis, weigh the pros and cons, and recommend the best option for your case.



What Level of Post-Migration Support and Maintenance Do You Offer?



And one of the last but not least application modernization questions is the level and quality of post-migration support your vendor are about to offer. There're key processes that cannot be neglected: real-time monitoring and performance optimization, 24/7 incident resolution, and robust security management to address vulnerabilities and maintain compliance with standards like GDPR or HIPAA. 



Over time, maintenance also involves resource and cost optimization to maximize the efficiency of cloud services, along with regular updates and compatibility checks to ensure applications and data remain up-to-date and fully functional.



Our Experience



We at ModLogix understand and value the importance of the criteria we have covered in our article. ModLogix is a company that helps businesses move their data to the cloud. We will accompany you at every step, from the discovery phase to ongoing monitoring after completion. Having substantial experience in cloud migration of varying complexity, we will provide you with comprehensive information and answer application modernization questions that may arise.

Read this true and dramatic story from our team. 



Contact the best specialists at ModLogix to receive a consultation and begin your migration as soon as possible. 



Conclusion



As risky and challenging as cloud migration can be, it is becoming a necessity, not an option. Cloud computing ensures flexibility, cost reduction, automatic updates, quality assurance, and improved security. However, finding the right legacy application modernization vendor is also an essential part of a successful transition. Ask the questions, read case studies, and make sure the vendor is worth your time and money.

Picture the team tasked with updating the UI of a legacy app. Traditionally, designers and developers would spend hours on layout brainstorming, sketching wireframes, and iterating designs. 



With generative AI, much of that groundwork is covered. AI taps into patterns from prior designs, brand guidelines, and best practices to create an initial layout—buttons, color schemes, font styles, all mapped out. The team now has a foundation ready to refine, saving precious hours that can go into perfecting user interactions instead.




Layout and Style Suggestions




Generative AI goes a step further by suggesting layouts that have been optimized based on user behavior insights and industry trends. It might flag that a critical action button should move to the top right to increase visibility or that a particular color combination could better align with user expectations. These minor but impactful tweaks ensure that the UI isn’t just visually appealing and more intuitive, reducing user friction down the line.




Backend Integration with Frontend Design




Legacy systems often have rigid backend architectures that weren’t designed to communicate smoothly with modern frontend frameworks. Generative AI simplifies this integration by generating backend code tailored to meet modern front-end requirements, bridging gaps between outdated systems and contemporary UI designs. This automation allows developers to focus on refining the user experience rather than manually adapting legacy backend code.



Development




Automated Code Generation




In the development phase, generative AI functions like a well-prepared assistant, automating code generation for boilerplate code, core functions, and specific libraries suited to the project’s needs. AI generates code from high-level instructions, such as defining how a feature should handle data, which cuts down on manual coding. 



This lets developers jump straight into refining the code rather than building it line-by-line. It allows them to focus on nuanced adjustments that improve application performance and compatibility with legacy systems.




Continuous Code Optimization




Over time, as the application evolves, the AI doesn’t just sit idle. It’s continuously analyzing and refactoring code, suggesting tweaks that improve performance or reduce complexity. If a function could be optimized to run faster or if a particular block could be written more cleanly, AI surfaces those suggestions. It’s like having a senior developer constantly review the codebase, catching inefficiencies that might be overlooked.




Infrastructure as Code (IaC)




Deploying legacy applications across modern cloud environments can be a challenging task. Generative AI addresses this by creating Infrastructure as Code (IaC) templates specifically adapted for legacy architectures, setting up secure and consistent environments that can run legacy applications effectively. This ensures that older systems can operate in cloud environments without the risks of misconfiguration or security gaps.



Testing




Automated Test Case Generation




Testing can often feel like finding a needle in a haystack, especially with legacy code that might lack documentation. Here, generative AI jumps in to generate comprehensive test cases. Developers can rely on these AI-generated test cases to cover all critical paths, freeing them from writing every single one manually.




Bug Detection and Weak Spot Identification




As the tests run, generative AI also acts as a keen-eyed inspector, hunting down bugs and pinpointing areas prone to failure. If a section of code is overly complex or handles sensitive data, the AI can flag it, allowing the team to address these issues before they become costly production errors. It’s like having a virtual safety net, ensuring nothing critical slips through.




AI-Driven Quality Assurance (QA) Insights




Once the testing phase wraps up, AI provides more than just a “pass” or “fail” report. By analyzing patterns across test results, the AI offers insights into recurring issues, stability metrics, and areas that may benefit from code refactoring. This allows QA teams to prioritize fixes based on impact, giving them a clear path to delivering a stable, polished product.



Deployment and Maintenance





Generative AI can assist with deployment by streamlining some configuration tasks, helping automate certain security checks, and generating template-based release notes. 





However, while AI can support monitoring by analyzing system performance and flagging potential issues — fully predicting and autonomously suggesting fixes remains a developing area. AI provides valuable insights and identifies patterns to help teams proactively address issues, but human oversight and intervention are often required.

1. Data Availability and Quality



Generative AI thrives on high-quality data to train, optimize, and produce reliable outputs. However, legacy systems often contain outdated, fragmented, or inconsistent data, which can lead to unreliable AI results if not addressed. 



Tip: Before implementation, it’s essential to assess the quality, volume, and accessibility of the data within your existing systems. Filling gaps and ensuring datasets are comprehensive and current will set the foundation for dependable AI-driven modernization.



2. Understanding the Complexity of Legacy Systems



Legacy systems often contain complex, intertwined code that can be challenging to break down. Evaluating how well generative AI can interpret and work within this context is essential. Not all AI tools can handle highly customized or niche codebases without considerable adjustments.



Tip: Start with a pilot project on a less critical system part. This helps determine the AI’s ability to manage complex code and highlights limitations before committing to larger-scale modernization.



3. Resource Requirements and Cost



Generative AI can significantly accelerate application modernization, but it also demands substantial resources—particularly for models that need high processing power and frequent retraining. Modernizing legacy applications with these models requires careful budgeting for cloud computing, data storage, and ongoing maintenance, as costs can quickly add up as the project grows.



Practical Tip: When budgeting for AI-driven modernization, start by comparing costs across various AI models. Consider whether simpler models can achieve the accuracy you need without the hefty price tag. Evaluate your cloud provider’s options for scalable resources so you can adjust usage as demands change.



4. Integration with Existing Tools and Workflows



Integrating generative AI with legacy systems presents unique challenges, as older platforms often lack compatibility with modern tools and may require significant workarounds. Legacy systems can resist seamless connections to CI/CD pipelines or code repositories, making it harder to adopt AI without creating disruptions. 



Tip: Identify which tools and processes you plan to keep and assess whether the generative AI solution offers native integrations or requires custom API development. Look for solutions with strong integration capabilities to reduce the effort needed to adapt your toolchain.



5. Security and Compliance



Generative AI brings added security considerations, especially when accessing sensitive data. Implement access controls, encryption, and monitoring for AI tools interacting with legacy codebases and outputs that touch production environments.



Tip: Ensure the generative AI solution complies with industry regulations, such as HIPAA for healthcare or GDPR for data privacy. Verify that it has robust security protocols, like data encryption and access logs, to safeguard sensitive information.



6. Interpretability and Control



Integrating generative AI into legacy systems can introduce a new layer of complexity, especially when transparency is essential. Unlike traditional rule-based systems, legacy systems often provide clear, predictable outputs, whereas generative AI models can act as 'black boxes,' producing results without easily traceable decision-making paths. For industries like finance and healthcare—where explainability is critical—this lack of transparency can be a major hurdle.



Tip: Choose AI models with interpretability features or create guidelines for validating outputs. Working with interpretable AI helps maintain control and allows for better risk management, especially when handling critical applications.



7. Team Training and Change Management



Integrating generative AI will require team buy-in and potentially new skill sets. Developers may need training to work with AI-driven outputs, while project managers must understand AI capabilities to set realistic goals and expectations.



Tip: Provide hands-on training and practical resources to familiarize your team with the AI tool and its outputs. Establish a change management plan that includes regular feedback sessions to address issues and improve the AI’s fit within the team’s workflows.



8. Scalability and Long-Term Maintenance



Generative AI needs continuous improvement and maintenance, including model retraining and updates to reflect evolving system needs. Plan for a scalable approach that accommodates both immediate requirements and long-term growth.



Tip: Start with a modular, scalable architecture that allows incremental updates. Document AI models and workflows so that future iterations and retraining are easier to implement and align with ongoing changes in business requirements.



9. Evaluating ROI and Performance Metrics



Before adoption, define clear metrics to measure the impact of generative AI on application modernization. Metrics may include reduced development time, decreased error rates, or improved code quality. Regular performance assessment will help you gauge ROI and make necessary adjustments to maximize AI’s value.



Tip: Set benchmarks and KPIs for each stage of AI integration. Regularly review these metrics to ensure the AI continues to deliver value and adjust as needed to enhance performance.

Categories of Core Banking Services



Core banking services are the foundation of a bank’s operations, covering everything from processing customer transactions to managing accounts. They all need a modern core to function correctly. Here are the most common categories:



Essential Services 



These are the backbone of daily banking. They handle daily banking transactions like deposits, withdrawals, and transfers, making it easy for customers to manage their accounts. They also include loan processing, covering from applications to repayments. 



Additionally, essential services involve payment processing, which keeps transactions smooth across methods like ACH transfers, wire payments, and card processing. These services keep banking reliable and seamless for customers.



Supplementary Services 



They add that extra layer of value, making digital banking more personalized. For example, they include wealth management, offering customized investment advice, portfolios, and retirement planning. This also comes with insurance options, like life, health, and property coverage. As for business clients, they benefit from trade finance and treasury management, which support things like international trade and cash flow.



Customer Engagement and Digital Channels 



This category makes it easy for banks to connect with customers wherever they are. It involves mobile and online banking, which allows customers to handle their finances anytime, anywhere. Customers have access to features like real-time alerts and mobile deposits, and with omnichannel support, banking is seamless whether customers are using an app, an ATM, or visiting a branch. Moreover, CRM systems help banks track interactions, allowing for a more personal touch. 



Regulatory and Compliance Management Services 



It helps banks stay in line with legal requirements while managing risks. For example, AML (Anti-Money Laundering) and KYC (Know Your Customer) systems monitor transactions and verify identities. This prevents fraud and ensures regulatory compliance. Data privacy and security measures are also available to protect customer information according to standards like GDPR and CCPA. 



Financial Reporting and Analytics 



Provides the insights banks need to make data-driven decisions and remain compliant. To be precise, financial reporting tools produce essential documents for regulatory compliance and strategic planning, while advanced analytics generate insights into customer behavior, market trends, and operational performance. By leveraging these analytics, banks can optimize their services, better understand customer needs, and refine their marketing strategies​.



Back-Office Operations and Automation 



It makes the behind-the-scenes work of banking more manageable and more efficient. This includes tasks like transaction reconciliation and settlement processing, which ensure that all activities are recorded accurately. Many banks also use robotic process automation (RPA) to handle repetitive tasks, such as data entry and transaction processing, freeing up staff for more critical work.



Main Factors Behind Banking Modernization



Several factors drive the need for core banking modernization. These include pressure to expand product lines, address legacy core system limitations, and keep pace with regulatory changes. Let’s explore these factors in detail.



Rising Customer Expectations



Customers now expect instant, personalized banking experiences similar to those offered by tech companies. This is probably what motivated DBS Bank in Singapore in its recent project. They used AI and machine learning to transform their existing core systems, offering personalized financial insights through their “NAV Planner” tool. Modernized systems enable banks to deliver real-time, data-driven services that anticipate customer needs, improving engagement and satisfaction​.



Challenges with Outdated Legacy Systems 



Legacy systems, many built in the 1980s, are monolithic and often difficult to modify or scale. This is why, for example, the Commonwealth Bank of Australia (CBA) spent over a decade and $1 billion on a core banking platform modernization, transitioning from a legacy system to a platform that supports real-time transactions and digital services. This upgrade was part of their business strategy to achieve a faster operating income and growth rate compared to expenses. It demonstrated that when you embrace digital transformation, you improve efficiency and profitability.

Expanding Product Lines and Service Channels 



Banks are under pressure to expand their offerings and meet new customer demands. Many are turning to digital-only services or specialized lending products to stay competitive. For example, Standard Chartered launched “Mox,” a virtual bank in Hong Kong that operates solely through a mobile app, thanks to its upgraded core system. 



A traditional core often lacks this flexibility for rapid product development, which is why banks are moving to more agile, omnichannel systems.



Competitive Pressures from Fintechs and Big Tech



Fintechs like Chime and Revolut and giants like Google and Apple are shaking up banking with digital, low-cost services. To keep up, traditional banks like JPMorgan Chase are modernizing their systems to quickly launch digital products, staying competitive in this fast-paced, tech-driven market. This helps them adapt and meet evolving customer expectations.



Integration and Open Banking



Modern banking depends on partnerships and third-party integrations through open banking, which requires flexible systems. BBVA, for instance, used open banking to collaborate with fintechs by leveraging APIs to expand its services. This was made possible by investing in a core system that supports external connections with third-party providers and meets interoperability standards, enabling them to innovate and collaborate more efficiently.



Regulatory Compliance and Security



Data privacy and security regulations are constantly changing, with mandates like GDPR and PSD2 in Europe imposing strict compliance requirements. Legacy platforms can make adapting to these changes cumbersome and costly. To handle this, HSBC implemented a cloud-native core system allowing faster compliance updates and advanced security features, such as AI-driven fraud detection. This helps the bank stay compliant while proactively managing risks​.



Operational Efficiency and Cost Reduction



Maintaining old systems is expensive, with high costs for hardware, software licenses, and skilled staff to support outdated technology. Case in point: by moving to a cloud-based core platform, Capital One reduced operating costs by eliminating on-premise infrastructure, improving scalability, and reducing downtime. As a result, Capital One could reallocate savings toward customer-focused innovations​.



The Banking Modernization Blueprint: Choosing the Optimal Approach



Core banking modernization is essential but complex, and banks have several strategic paths to choose from based on their needs. Here are some main approaches they can explore, each with its advantages:



Re-platforming Solutions



Re-platforming shifts a core banking system to modern architecture, like cloud infrastructure or microservices, reducing costs by eliminating the need for on-site hardware. This approach enhances scalability and resilience while enabling real-time data access and features like automated compliance updates, which are vital for regulatory needs. Around 32% of banks focus on digital differentiation through modernization, aiming for faster product launches and better customer experiences with cloud-based solutions.



Refactoring for Flexibility



Refactoring legacy code uses microservices and APIs to break large core systems into smaller, modular parts. This allows banks to update specific areas, like payment services or data management, without overhauling everything. By separating front-end from back-end components, banks can roll out new products faster and connect more easily with external partners. This approach is especially useful as 53% of banks focus on staying agile to meet changing customer needs and adapt to modern technologies.



Replacement with a New Core System (Rip-and-Replace)



A rip-and-replace approach completely swaps out the legacy systems for a new core banking platform, often cloud-based and API-enabled. While this method is resource-intensive and carries some risk, it gives banks a fresh start with maximum flexibility to adopt new technologies. Today, about 63% of banks plan to move their mainframe workloads to public cloud-native environments, which can provide added cost-efficiency.



Progressive Modernization (Hybrid Approach)



Progressive transformation allows banks to upgrade gradually by updating parts of the system over time. This might include adding a digital front-end for a better customer experience while keeping the legacy back-end. This phased approach reduces business disruption and spreads out costs. It’s a modernization plan for banks that need to balance ongoing operations with transformation.



Legacy Core Systems vs. Cutting-Edge Next-Generation Platforms



Legacy core banking systems, often built in the 1980s and 1990s, rely on monolithic architectures that were once robust but are now rigid and costly to maintain. These systems use outdated programming languages like COBOL and operate on mainframes, making it difficult to scale or integrate with modern digital tools.

In contrast, next-generation platforms use modular, cloud-native architectures that provide flexibility, scalability, and support for real-time processing, enabling banks to adapt quickly to changing technology and customer needs.



Characteristics of Legacy Core Systems



Legacy core systems were built to handle basic banking tasks like account management and loan processing using batch processing, which often causes delays and inefficiencies. They’re heavily customized to each bank, making upgrades complex and risky. 



With limited integration capabilities, these systems need help to support open banking or advanced technologies like AI and real-time analytics. This lack of flexibility is a major drawback in today’s banking world, where speed and adaptability are essential to meet customer demands in the increasingly crowded market.



Next-Generation Platforms



Next-generation core banking platforms use microservices and API-driven architectures, making it easy to integrate with third-party applications and adopt new technologies without significant reconfigurations. They support real-time processing, enabling instant updates and transactions that boost customer experience and efficiency. 



Typically cloud-based, they reduce dependency on expensive hardware and scale quickly to meet peak demands. Enhanced security features, like AI-driven threat detection, are also built in — an essential factor as 88% of companies are willing to pay extra to work with a bank that has a strong security policy and a proven security track record.



Strategic Considerations for Banks 



When modernizing core banking systems, banks have various options to consider. Choosing the right approach, however, depends on specific needs, existing limitations, and long-term goals.

### Legacy Code Refactoring: Tips, Steps, and Best Practices

As your company or product grows, chances are your code has passed through several developers, and the code base is no longer neatly structured but continually patched. Having a software application that freezes, crashes, and behaves abnormally is a company's worst nightmare.  



Apart from staining your brand's reputation, this can limit your company’s ability to scale. A decade-old generic software with crufty legacy code messes with the functionality of your software application, creating technical debt and stunting your company’s growth or worse, normal functionality. 



So, what do you do when you find yourself with a clunky, outdated, and messy code, which is harder to reuse and test?



There are two options, you can either rewrite the entire code or refactor it. On the one hand, rewriting is quite easy for the developers but comes at a hefty price. And on the other, you can save costs through legacy code refactoring, which is significantly cheaper but may be also very difficult. The good news is that it’s possible to fix it without the need to disrupt the entire company’s internal and external processes. In this short and to-the-point article, we are going to walk you through the process of legacy code refactoring, revealing the common pitfalls and how you can dodge them and get clean code.



So, What is Refactoring Legacy Code?





Refactoring legacy code is the process of improving the structure of an old or unfamiliar code without changing its functionality. The idea is to clean up lines of complex codes so you can understand or work with them better. This may include reducing redundancies or errors to make the code readable and manageable.



While refactoring a legacy code may sound similar to rewriting it, they differ. 





In a code rewrite, developers would remove nearly everything to create a new code and implement new functionality from scratch. Refactoring is less extreme. Think of it like editing your old high school paper. When you review it, chances are you may find wordy sentences or repetitions that serve little use to the essay. When you improve these words without altering the meaning, that's refactoring for programmers.













Legacy code refactoring works on the basic principle of cleaning up the code base to improve its performance, making it readable and easy to maintain.



There are various benefits to careful refactoring legacy code. For starters:




It makes code easy to understand: Refactoring code involves restructuring code in such a way that a new developer can work on it with minimal difficulties. When it’s understandable, identifying and fixing bugs becomes effortless.



It enhances maintainability: Organized code is easy to maintain and improve. It also makes updating the code pretty much straightforward.



It improves an application’s performance: With less complex codes, a software application functions faster.



It is cost-effective: In the long run, simplified and restructured code will be efficient. It also minimizes the risk of bugs, which is time and cost-saving. 




It provides technical support: Technical support allows you to use third-party APIs that improve the functionality of your enterprise application. You will also receive updates that fix bugs and repair existing security holes.



Legacy Code Refactoring vs. Code Rewriting: What to Choose



Rewriting is another solution to dealing with unmanageable codes. As opposed to testing and refactoring legacy code where a developer makes micro changes to an application, code rewriting (as the name suggests) is scraping away the code and building it again from the ground up.



So, when can you rewrite the code over legacy code refactoring?



Despite being a daunting task, rewriting is a viable option if you need to dramatically switch the application’s architecture. It is also the case when the application’s tech is turning obsolete, only supports previous versions of the system, and cannot integrate with advanced applications. 



Take the example of AngularJS.



It was not long ago when Google discontinued support for AngularJS. As a result, companies that use the programming language for their web applications will no longer receive updates and cannot leverage third-party APIs. In this case, considering migrating AngularJS to Angular is a necessary step.



Legacy code refactoring alone won't work here. You do need to makeover the entire application and rewrite codes afresh due to differences in frameworks. 



 VIEW CASE STUDY  







On the other hand, who should refactor legacy code?



If the application is an integral part of business processes and stopping it will cause too much downtime, refactoring it is an excellent idea. This also applies if the primary app developers are available and can work on the software.



Pros and cons of code rewriting



Rewriting code allows you to change code, improving it however you deem fit. It also does away with legacy code that can make system integrations near impossible. 



Even so, rewriting is time-consuming. Developers need to take time to understand the application, identify the must-have functionalities, and devise ways to incorporate them into the new code. Additionally, the risk of developing new bugs and defects is high.



Pros and cons of code refactoring



One of the major advantages of refactoring in a legacy code is that it can be done to any software architecture. It also improves the quality of code without unnecessary downtime, and developers can choose to isolate a specific codebase and work on it independently, which significantly minimizes development costs. 



However, since legacy code refactoring does not tamper with the functionality of the application, you cannot add new features. It also requires robust skillsets to simplify the code, as the process is often complex.











All in all, before you decide on whether to rewrite the code from scratch or refactor it, you need to scrutinize each option, choosing the most valuable strategy in terms of complexity, cost-effectiveness, and time used in the development process. 



Want to know more about rewriting, refactoring, and rebuilding? Read this article. Should You Rehost, Rebuild, or Rewrite a Legacy Application With Latest Software? 



Refactoring Code vs Rebuilding the System



Rebuilding is also one of the methods used to improve or change software, but it differs significantly in scope and complexity from refactoring. Let's focus on rebuilding pecularities.



Rebuilding involves a complete overhaul of the system architecture or codebase. This is usually done when incremental improvements (refactoring) are no longer sufficient, and the current system cannot support the necessary changes or future growth. Rebuilding is often a last resort when an application’s technical debt has become unmanageable or the software is no longer scalable. For example, switching from a legacy monolithic system to a microservices architecture allows greater scalability, flexibility, and resilience.



Rebuilding is far more complex and time-consuming than refactoring and rewriting for several reasons:




Complete redesign - rebuilding usually requires a complete redesign of the application’s architecture, often switching to a new framework or even tech stack.



Data migration - when rebuilding, data from the old system needs to be carefully migrated to the new system, which adds risk and complexity.



Risk of downtime - rebuilding can introduce a higher risk of downtime, as the old system is often replaced by the new one all at once or in phases.




So, when rebuilding is necessary?



Fundamental architecture limitations - when the system’s architecture is no longer scalable at all or able to handle growing business demands, refactoring or rewriting small parts won’t resolve the issue. Rebuilding the system entirely with a new architecture is essential for future scalability and flexibility.



Inability to support new features or business requirements - integrating AI-driven analytics or advanced machine learning may require a complete overhaul of the system, particularly when the existing architecture doesn’t have the infrastructure to support such features.



Obsolete technology stack - when the current technology stack is outdated, unsupported, or incompatible with modern tools, rebuilding the system with a more up-to-date stack may be necessary. 



Cost-effectiveness and long-term maintenance - in cases where maintenance costs and time are disproportionately high due to inefficient code or outdated systems, a rebuild can provide a cost-effective solution. While refactoring may improve parts of the system, the overall cost of maintaining a patched-up system could be higher than rebuilding one designed for modern use cases.



To sum up, rebuilding is necessary when the system's limitations — whether due to technology, performance, or scalability — can no longer be resolved by incremental improvements or refactoring.



Simple Steps to Refactor Legacy Code Base



Every developer has a methodology for refactoring legacy code that’s unique to them. However, all of them conform to a few basic steps when integrating legacy systems.



Here is a simple step-by-step guide on how to start refactoring legacy code.







Identify the flaws and flows



In many cases, legacy code has more than one flaw. And improving its internal structure starts with identifying the root problems.



For instance, if you are refactoring PHP legacy code and you are dealing with old-fashioned core functionalities, you first need to identify how well-documented, operational, and scalable the PHP application is. 



Performing a comprehensive application audit is instrumental when working effectively with legacy code, as you gain viability into the faulty flows and their dependencies.



Break monolith code



Effectively refactoring code requires you to split each monolith code, separate them into focused classes, modify the code, test, and release the refactor thereafter.



Splitting code is an integral part of the refactoring process as it improves readability, helping the developer to focus on specific modules, and gain an in-depth understanding of the existing codebase. They will then be able to accurately picture their objective and articulate their next steps.



Extract logic code and apply the basic refactoring tips



The next phase of refactoring is to extract each flow’s set of principles necessary for the proper functioning of the application. Rewrite it, taking a more straightforward approach. 





Write code bearing in mind the effective coding principles. Doing so makes the code highly scalable, allowing you to add a dependency if need be. However, first, you need to concentrate on the logic iteration you are working on before you can think of the dependencies. And then, test!





Undertake all these while staying true to the basic principles of legacy code refactoring is imperative. For starters, you need to refactor in small bits rather than in large batches. Also, instead of refactoring the entire UI only work on specific codes that affect the particular business request. 





Choose your desired architecture



Choosing the right software architecture is of the utmost importance as it plays a vital role in how the application handles the functions it was designed for. It also determines the hurdles you might face during implementation.



Before picking the desired architecture, you need to consider component interactions, the application’s scalability, and adaptability. Some of the architectures you can pick from include layered, microservices, event-driven, and space-based architectures. If you are indecisive and having problems picking one, you can always mix multiple architectures.

### How to Estimate the Cost of Cloud Migration

How much does cloud migration cost? This is one of the most frequently asked questions by businesses burdened by legacy systems. While the final cost of moving to the cloud is exceptionally project-dependent, there are still some frameworks, approaches, and strategies to make a quite accurate estimation at the beginning of the migration process. 



In this article, we will discuss how to estimate the cost of cloud migration and which specific points to keep in mind. 



Cloud Migration Cost: Definition and Milestones



Cloud migration costs are the expenses covering the process of transferring data from previously used legacy software that no longer performs its functions to the cloud environment. The process as a whole is quite complex and challenging. 



What’s more, there are always many project-specific tasks and bottlenecks, which are difficult to perform in cloud migration estimation. That’s why 50% of companies that recently moved to the cloud reported that estimating the cost and staying on a budget was the biggest challenge for them. The cost of moving to the cloud may be high, but the cost of not moving to the cloud is even higher. Let’s look through the cost breakdown.



What cloud computing benefits exist for every organization? Read in our blog post. 10 Key Advantages of Cloud Computing for a Business 



The Cost of Moving to a Cloud Environment by Milestones



Before launching a cloud data migration project or building a cloud-based architecture for apps from scratch, you have to take all the pitfalls into account, develop a data migration strategy and foresee the associated risks. Feel free to use our dedicated guide as your starting point. 









The first step is choosing the type of cloud solution that suits your business. There are public, private, and hybrid clouds, and the features of each one can be tailored to the business specifics.  





Next, you have to choose a cloud service model and only then proceed with cost allocation and distribution. In a nutshell, data migration means switching from capital expenditures (CapEx) to operational expenditures (OpEx).  





In most cases, the latter model is always more feasible since you are moving from traditional hardware and software ownership to an as-a-Service model, which may cover Software as a Service, Infrastructure as a Service, Platform as a Service, and Artificial Intelligence as a Service. Compared to these models, traditional hardware requires much more investment in its purchasing or paying software license fees.



Regardless of the model you choose, the cost of moving an application to the cloud can also be evaluated according to the data migration project milestones. Each of them should be planned and estimated separately to develop a holistic picture and realistic budget.



Pre-migration



This initial stage usually concerns defining the reason for switching to the cloud environment, pinpointing core pains, evaluating the amount of data you have to transfer, and choosing the cloud provider you would like to go with. All these preliminary measures should already give you a big picture of the related costs to expect. 



At this stage, your cloud migration cost will be related to the following aspects:




On-premise data management, which includes preparing to cover expenses for establishing and managing:

new storage, infrastructure operation, server powers, performance resources consumption, compensations for involved experts, software licensing, maintenance of the new hardware, warranties, tech support, and necessary app updates.











Database upgrade — your DB must be compatible with the specifications of the new system you are looking to migrate to. This may require a software upgrade that may occur beforehand, either on-premise or in a specified public cloud infrastructure environment — processes spawn completely different scopes of expenses.









Consultations of cloud migration vendors — this kind of assistance may be precious for your migration project if you lack in-house specialists savvy in the whole process.









Testing the demo versions of cloud solutions — here, a testing cloud environment rent must be covered.









Possible Proof of Concept — it can help you determine how the whole data migration intention fits your business needs in real life and estimate costs more clearly before going for full-on migration.




Don't forget to clarify these 10 things for the successful cloud migration. 10 Critical Questions About Migration to the Cloud 



Migration



This is the most time and money-consuming process since, at this stage of cloud migration, your data should be accurately classified according to the platform's requirements and securely transferred to a new system. At this step, you will have to pay for:




The migration itself — the fee you will need to pay to the cloud vendor for migrating to their system, plus the labor costs of your data migration company if you hire a third-party team for this project. You should also remember that if your legacy system continues to work during data migration, you will incur additional costs on the system support and syncing up the data. 









Application and code changes, new infrastructure development, and setting a new system up according to your business requirements. 









Refactoring, i.e., making your applications and data new system-compatible where it couldn’t be prepared at the pre-migration stage.




Post-migration



Post-migration involves taking care of the proper further support for your cloud infrastructure, which implies:




Monthly or yearly licensing or support costs of maintaining the established infrastructure and related software. 









System operations and maintenance, administration, monitoring, updates, and staff training on the new system. 




The costs could also be classified as direct and indirect. While the first ones are related to the data migration process precisely (for example, the cost of hiring a dedicated data migration team), the second ones are mediated expenses (for example, the cost of supporting your legacy system during data migration).



Hidden Costs in Cloud Migration You Should Be Aware of



Some cost of moving to the cloud can catch organizations off guard. Here are key hidden expenses to watch out for:




Data transfer costs - migrating large datasets and ongoing data transfers (egress fees) can be expensive.



Overprovisioning - without proper resource management, overprovisioned VMs or storage can drive up costs.



Management tools - third-party tools for monitoring and managing cloud services add to ongoing costs.



Downtime and migration issues - unforeseen challenges during migration can result in delays and extra costs.



Reserved instances - misestimating resource needs can lead to underutilized, costly reserved instances.



Third-party integrations: Integrating cloud services with legacy systems or SaaS tools may require additional licenses or fees.



Exit costs - migrating out of the cloud involves data egress fees and significant labor costs.




Proper planning and continuous monitoring are essential to avoiding these hidden cloud migration costs.



Factors Affecting the Cost of Moving to the Cloud



According to the research, “The blunt answer to the question ‘How much will a migration cost?’ is, “It depends.” So, the final cost of cloud migration depends on the following factors. 



The size of the cloud migration project



The size of the cloud migration project also directly affects its cost. For example, the cost to migrate the data of a medium-sized company will be lower compared to the cost of data migration from a multi-tenant system. The latter case means more requirements to the system workload and, consequently, more efforts to plan the project, outline your strategy and allocate a budget.







Tip: Regardless of the project side, there are some opportunities for cost savings of moving data to the cloud and mitigating related risks. For example, moving all the data you have to the cloud will always be more expensive than a step-by-step migration strategy. That’s why you can consider getting started with migrating the most crucial data and operations as the first step towards data migration. 



Moving, integrating, and testing challenges and specifics



The most common challenge in moving data to the cloud is to keep the legacy system working to avoid downtimes. That is, the business owner and the database migration services provider should think about it in advance. 



Third-party support



The fee you have to pay to your migration vendor may also be different, and in this case, the company’s location isn’t the only factor that matters. Different companies use their practice-proven sets of tools and approaches, and in this case, you are paying not only for service quality but also for the vendor’s reputation, reliability, and data safety. The time spent on the data migration process may also vary depending on the company’s experience and expertise.

Chosen cloud services



AWS, Azure, and Microsoft offer different pricing plans to use their solutions. Still, their offers are pretty diverse to find the one that suits your business needs most, but this is one more factor that affects the cost of moving to the cloud.



Challenges in Cloud Migration Cost Estimation



There're several cloud migration cost estimation challenges, like:



Complexity of Applications: Legacy applications may require refactoring or re-architecting for the cloud, and estimating these efforts is often complex and uncertain.



Unforeseen Performance Issues: Unexpected performance bottlenecks during migration can lead to additional expenses for troubleshooting, scaling, or optimizing infrastructure.



Vendor Pricing Complexity: The varying pricing models and service tiers offered by cloud providers can make accurate forecasting difficult.



Unpredictable Data Transfer Costs: Estimating data transfer, particularly egress costs and migration bandwidth, can be difficult, as it depends on the volume and frequency of data movement.



3 Approaches to a Cloud Migration Cost Estimate 



How to estimate the cost of moving to the cloud? Below are three main approaches.



#1 Analogy Approach



As the name suggests, this approach allows for estimating cloud migration cost by following the logic and milestones of some previous data migration projects. Keep in mind that, in this case, you have to partner with a data migration vendor with experience in moving data to the cloud for the business from your niche.  



#2 Expert Judgement Approach



According to this strategy, the cost estimate is made proceeding from the knowledge, expertise, and competency the development company already has. Since moving data to the cloud is one of the decisions modern businesses frequently make, getting in touch with the experts on this matter shouldn’t be a challenge.



#3 Algorithmic Model Approach



This methodology implies coming up with a formula to establish the relationship between dependent and non-dependent variables. This approach may be used for rough calculations only since it can’t take the project’s specifics into account.



The same approaches are also suitable when building a cloud-based for apps. 



How to Estimate the Cost of Cloud Migration







1. Take inventory of your current IT infrastructure



At this stage, you have to analyze your current costs, set the cost reduction metrics you want to achieve, and shortlist the first data arrays and operations you would like to move. 



2. Find out the cost of using a cloud service 



Plan the migration with the help of a cloud migration costs calculator. Below are the calculators shared by the most popular cloud providers. You may find out the approximate price for using their solutions by specifying your workload and the necessary computing power, request processing time, and other important factors. We recommend using these cloud cost calculators:




Google Cloud Platform Pricing Calculator









Microsoft Azure’s Pricing Calculator









Rackspace’s calculator









IBM Bluemix’s calculator




To come up with more realistic estimates, consider getting in touch with a cloud migration vendor. Their practical experience can be quite helpful if you intend to hire a dedicated team for cloud migration. You can also ask your in-house consultant for support and check the estimates from both sides. 





3. Calculate your cloud migration costs with your migration vendor. 



As you partnered with a cloud migration vendor to evaluate your project specifics, get competent consultation on a final cloud provider choice, and estimate your costs more accurately. 





Consider partnering with those with experience in legacy system migration to be sure about your data safety and with diverse experience in data migration, since in this case, the company will be better able to predict the possible challenges and bottlenecks and estimate the final cost more accurately.

#2 Choose the right strategy



There are a lot of legacy system modernization strategies such as rehosting, re-platforming, etc. All of them have their technical specifics, but choosing the right strategy will allow you to achieve the highest efficiency at the lowest costs. 



#3 Choose an effective pricing model suitable for your business needs



Since cloud solutions are provided to the companies according to the Software as a Service business model, you may pay for the resources actually used. Still, the Pay As You Go approach may be quite costly, for example, if the working load suddenly increases. To find out the most effective pricing model, measure your current resource utilization and use this indicator as a reference when building a cloud architecture.



#4 Consider reserved instances for better predictable workloads



Reserved instances provided by Amazon AWS or Azure VMs are the cloud usage opportunities that allow you to set continuous computing power and its cost limits. Using this option is a way to create better predictable workloads and plan your cloud management price more accurately.

Preparing for AWS Migration



Before moving  from on prem to AWS, it's essential to assess your situation. Understanding your current environment and infrastructure helps identify your business's specific needs. As part of this on-premise to AWS cloud migration step by step approach, engage with stakeholders early to ensure alignment on objectives and resources. 



Next, develop a detailed plan with specific AWS migration steps to avoid pitfalls and set expectations. Additionally, evaluate data dependencies and ensure robust backups. Understanding how to migrate data from on-premise to AWS effectively is crucial for minimizing disruption and ensuring data integrity.



Assessing Your On-Premises Applications



Before migrating to AWS, thoroughly evaluate your existing applications.




Create an Inventory: Start by creating an inventory of all your on-premises software, including custom and off-the-shelf solutions. Identify each application's purpose, usage patterns, and dependencies.



Analyze Technical Aspects:  Next, analyze the technical aspects. Consider the programming languages, frameworks, and databases used, such as Oracle databases. Also, assess the application architecture and determine if it's compatible with cloud environments. In addition. some applications may require modifications, modernization, or complete redesign for optimal cloud performance.



Evaluate Resource Requirements: Evaluate the resource requirements of each application. This includes CPU, memory, storage, and network needs. Understanding these metrics helps in selecting the appropriate AWS database migration service and type.



Review Security and Compliance: Don't forget to review security and compliance requirements. Some applications may handle sensitive data, necessitating specific security measures in the cloud.



Prioritize Applications for Migration: Lastly, prioritize your applications for migration. Consider factors like business criticality, complexity, and potential cloud benefits. For example, 48% of companies first migrate their least critical applications as a learning experience.




Identify Your Business Objectives



Defining clear business objectives is crucial for a successful AWS migration. Start by asking why you're moving to the cloud. Are you aiming to reduce costs, improve scalability, or enhance performance? For instance, Netflix’s migration to AWS was driven by the need for a more scalable, reliable, and globally distributed infrastructure.



Perhaps your goal is to increase innovation or support remote work in your organization. Regardless of your specific aspirations, remember to consider both short-term and long-term objectives. Prioritize these goals based on their impact and feasibility, and align them with your overall business strategy to ensure consistency. 



Don't forget to consider customer needs and market trends. Also, remember to involve key stakeholders from different departments to ensure a comprehensive view. Teams from IT, finance, and operations often have valuable insights. 



Another valuable strategy is to set specific, measurable targets for each objective. This could include metrics like response times, uptime percentages, or cost savings. For example, you might aim to reduce IT infrastructure costs by 30% in the first year while enabling faster deployment of new features. 



Select Your Cloud Type



Choosing the right cloud type is critical to your migration success. The three main options are public, private, and hybrid clouds, each catering to different needs.




Public Cloud: This is Ideal for businesses looking to minimize infrastructure maintenance. AWS manages the servers, storage, and networking, allowing you to focus on your applications. This is cost-effective for workloads with variable demands.



Private Cloud: A private cloud offers dedicated resources for enhanced control and security. It is suitable for organizations with stringent compliance requirements or those handling sensitive data. It provides high customization and robust performance.



Hybrid Cloud: This option combines public and private clouds, offering flexibility. It allows you to keep critical workloads on-premises while utilizing the public cloud for scalable resources. This approach balances security, cost, and performance. For instance, a financial firm might use a hybrid cloud to keep sensitive data in a private cloud while leveraging the public cloud for customer-facing applications.




Compare Costs of On-Prem vs AWS



Is AWS really more cost-effective than an on-premises data center? Before migrating, it's essential to evaluate the costs beyond just hardware. Here are some key factors to consider:




Hardware and Storage: On-premise setups require significant investments in servers and infrastructure. AWS removes these upfront costs with a pay-as-you-go model, giving customers control over expenses. You only pay for what you use.



Maintenance and Labor: Maintaining an on-prem data center requires a dedicated team for hardware upkeep and software updates. AWS, on the other hand, manages these tasks, allowing your IT team to focus on more strategic initiatives.



Network Costs: On-premises solutions often incur high network costs for managing traffic and ensuring connectivity. By contrast, AWS provides scalable network options that can be more cost-effective, especially as your business grows.



Software Licenses: Traditional setups necessitate ongoing investments in software licenses. With AWS, many necessary tools and applications are included or available at a reduced cost.



Indirect Costs: Consider potential losses from downtime, technical errors, and decreased productivity with on-prem solutions. AWS offers high availability and robust disaster recovery, minimizing these risks.




Use tools like the AWS Total Cost of Ownership (TCO) Calculator to estimate your costs accurately. This tool can help you understand the financial benefits of moving to AWS, factoring in both direct and indirect costs. 



Prepare Your Team



Successful on premise server to AWS cloud migration requires a well-prepared team. 




Identify Key Players and Form a Dedicated Team: Begin by identifying key players who will lead the migration process, such as IT managers, database administrators, network engineers, and security specialists. Forming a dedicated migration team will help maintain focus on the project.

Provide training on Amazon relational database service to build confidence and minimize errors during the migration.Additionally, foster a culture of continuous learning. The cloud landscape is constantly changing, so your team should stay informed about the latest AWS features and best practices. Consider organizing internal knowledge-sharing sessions for team members to discuss new insights and challenges.



Establish Clear Communication Channels: Set up clear channels for sharing updates, concerns, and progress reports. Regular team meetings can help address challenges promptly and keep everyone aligned.



Implement Change Management Strategies: Some team members may be hesitant to adopt new technologies or processes. Address their concerns directly and emphasize the benefits of AWS migration for their roles and the organization.



Collaborate with AWS Experts: To enhance your team's skills, consider collaborating with AWS experts or consultants. These professionals can offer valuable insights and assist with complex migration scenarios. For example, When Dow Jones moved to AWS, they worked with AWS experts to conduct an AWS Well-Architected Review (WAR) of their platform.




Identify Your Cloud Migration Strategy



After evaluating your applications and setting clear business objectives, it’s time to pinpoint your cloud migration strategy. AWS outlines several approaches, but the most relevant for on prem to cloud migration AWS include:




Rehosting: The "Rehosting" or "Lift and Shift" strategy involves application migration from on premise to AWS cloud with minimal changes. This approach is quick and suitable for organizations looking to rapidly exit their data centers. It's often a starting point for further optimization.



Replatforming: "Replatforming" involves making minor adjustments to applications to take advantage of cloud benefits. This strategy balances speed and optimization, allowing for some performance improvements without major code changes.



Refactoring: For applications that need significant reworking, the "Refactoring" approach is ideal. This involves redesigning applications to be cloud-native, maximizing AWS capabilities but requiring more time and resources.



Retain: Sometimes, keeping certain applications on-premises makes more sense. This hybrid approach allows you to utilize the cloud's benefits for less critical applications while maintaining essential systems locally.




Some organizations opt for a phased approach, combining strategies. For instance, a retail company might rehost its inventory system while refactoring its customer-facing app for better scalability. Remember, your choice should align with your business objectives, resources, and timeline. Flexibility is key - be prepared to adjust your strategy as you progress.



Security and Compliance



Cloud security and compliance are top priorities for two-thirds of IT and security professionals—and they should be for you too.



Start with a comprehensive risk assessment of your current environment. Identify sensitive data and familiarize yourself with regulatory requirements specific to your industry, such as GDPR, HIPAA, or PCI DSS.



AWS provides strong security features, but proper configuration is essential. Implement robust access controls, encrypt data both in transit and at rest, and enable logging and monitoring. Use AWS Identity and Access Management (IAM) to effectively manage user permissions.



Consider leveraging AWS compliance programs like AWS Config to assess and audit your configurations. Many organizations have found that AWS can enhance their security posture. For instance, Capital One reported improved threat detection after migrating to AWS.



Don’t forget the shared responsibility model: while AWS secures the infrastructure, you are responsible for securing your data and applications. Regular security audits and employee training are vital. Keep in mind that compliance is an ongoing process, not just a one-time task during migration.



Technical Assessment



Evaluate your current applications to determine their suitability for AWS. Not all applications will migrate easily. Some may require redesign, while others can move as-is.



Ask yourself these questions:




Which applications depend on specific hardware or software configurations?



What level of customization do your applications need in the cloud?



How will performance change after migration?



What are the potential costs associated with migrating each application?



What is the potential return on investment for each application?




Select Your AWS Tools



One of the key benefits of AWS is its extensive range of tools designed to simplify your migration process. No matter the scale of your data or the complexity of your applications, AWS offers tools to meet your needs.



Here's a selection of key AWS migration tools and their core features:



ToolSummarized FeatureAWS Migration HubCentralized tracking of application migrationsAWS Database Migration Service (DMS)Migrates databases to AWS with minimal downtimeAWS Server Migration Service (SMS)Automates the migration of on-premises servers to AWSAWS SnowballTransfers large volumes of data securely and efficientlyAWS Application Discovery ServiceCollects data from your existing environment to map dependencies and estimate migration costs.AWS Schema Conversion Tool (SCT)Converts database schema to be compatible with AWS databasesAWS SnowmobileMoves exabyte-scale data, useful for extensive data center migrations.AWS DataSyncAutomates and accelerates data transfers between on-premises storage and AWS.AWS Transfer for SFTPSeamlessly migrates SFTP workflows to AWS without disrupting existing operations.AWS CloudEndure MigrationProvides continuous replication and automated orchestration for disaster recovery



When selecting tools, consider your specific migration needs. AWS Snowball, for instance, might be ideal if you're dealing with large datasets. This physical device can transfer up to 80 TB of data, significantly reducing transfer time and costs for large-scale migrations.



Select Your AWS Storage Options



AWS offers a variety of storage solutions for different needs. Consider factors like data type, access frequency, and performance requirements. For file storage, Amazon EFS serverless, fully elastic file storage is a scalable, fully managed option. Amazon EBS is ideal for block storage with EC2 instances, providing low-latency performance. For long-term archival data, Amazon Glacier is a cost-effective choice.



Data access patterns are also important. For infrequently accessed data that needs to be available immediately, S3 Infrequent Access is a good option. For hybrid environments, AWS Storage Gateway integrates on-premises and cloud storage efficiently.



Post-Migration Assessment and Upkeep



After completing your AWS migration, it's time to evaluate your systems and ensure they perform as expected. Revisit the key performance indicators (KPIs) set at the beginning to measure success. Regularly monitor performance metrics and compare them against your initial benchmarks. This will help identify any areas needing adjustment.



Familiarize yourself with AWS support tools and resources to maintain optimal performance. Services like AWS CloudWatch can help track system health, while AWS Trusted Advisor provides insights to optimize resources and enhance security.

### 3 Approaches for Safety Migrating a VB.NET App to a Web App

Visual Basic (VB) is one of the pioneers in object-oriented programming, which received immense popularity among thousands of organizations. Years ago, it was used to develop Windows applications and to interface database systems. Companies found it a helpful tool for creating effective solutions for business activities like marketing, accounting, financial planning, preparing payroll, procurement, order processing, etc. 



Now it's hard to number the applications built on Visual Basic and its dialects. Plenty of developers still remember classic Visual Basic with its last official version – Visual Basic 6.0, while someone got used to VB.NET, which arrived in 2001. All in all, the thing that unites them is an urgent need for an upgrade. VB-based applications inherited millions of lines of dead code, huge amounts of dependencies from third-party software solutions, and, of course, vulnerabilities.



Sooner or later, every company will make the tough call to migrate vb.net to a web application. What are the main approaches and implications of this process? Let’s look through the possible options.



Why Migrate a Desktop Visual Basic App to the Web Platform



Migration to the modern web environment is a thriving opportunity for organizations that are caged in the limitations of desktop apps. As for VB.NET apps, it's almost the last lifeboat for their owners to stay afloat. Microsoft has no plans to evolve Visual Basic as a language after 2020; thereby, it'll become harder to support and scale the existing solutions. This makes it prudent to switch to the best Visual Basic alternative, such as Python or Java as of 2024. 



As the troubles with Visual Basic apps are far from over, let's consider other reasons why it's worth thinking about migration.







Increasing shortage of technical professionals



How long have you met developers who are eager to work with Visual Basic code? Well, we neither. Their number is reducing dramatically as new languages appear and some of them reach retirement age. Notably, in 2016-2018, Visual Basic 6.0 was named the most dreaded programming language, according to Stack Overflow's annual developer survey.  



Therefore, it is tough to find a VB software development provider who can understand the old code and maintain it (or simply fix a bug). This is one of the cons of Visual Basic apps that should prompt you to migrate as early as now.



There are hurdles to maintain and extend the system



The lack of tech talents gives rise to another issue, implementing any changes to the system is like clearing a minefield. With no qualified engineers, fixing the legacy code could lead to devastating consequences, let alone adding something new. 



To support VB owners, Microsoft even announced the C# coevolution strategy starting from 2010. Now it's meant to be easier to deal with the existing desktop apps, but it doesn't exclude the necessity of moving VB.NET projects to the modern environment. The thing is, many libraries used in VB apps are severely outdated, and today they have no reliable analogs.

There are no equivalents for outdated components



Speaking of the outdated tech components and structure, VB applications have a Component Object Model (COM) at their core. Being highly complex, COM was used exclusively for Windows applications but now is not popular as Microsoft focused more on new .NET technologies. Integral parts of COM, OCX/ActiveX controls, and software modules designed to run on 32-bit applications, a part of COM, are not supported in VB applications as well.  



Many other third-party components and controls, based on VB solutions are also obsolete, prompting the need to replace them. Curiously, in the meantime, the new .NET 5 release includes the updates for the WinForms application framework.

The current solution suffers from performance issues



Slow response time and frequent downtimes are common disadvantages of VB.NET applications. In 2019, owners of Visual Basic 6, Visual Basic for Applications, and VBScript experienced a global outage. After installing the planned security update KB4512506, the apps stopped working. Of course, Microsoft patched this issue, though the company wasn't obliged to do it.  



Obviously, high performance isn't Visual Basic forte. Thus, companies look for some alternative backend solutions instead of physical or dedicated servers.



3 Approaches to Transfer a Desktop Visual Basic App to a Web App Safely



There are three main approaches for converting a visual basic application to a web application, and they are supported by the official Microsoft community. Despite the depreciation mode, there is a lot of documentation on modifying and porting VB.NET and VB applications. In addition, Visual Basic formed a strong developer community that shares best practices for dealing with apps. As a rule, developers use Visual Studio to implement the given recommendations.  



What can you do to make your Visual Basic software web-friendly?







#1 Extend with C# capabilities



So as not to fully recreate the app in the new environment and violate its initial structure, you can leave the original application as it is (plus fixing minor bugs) and plug in extra functionality. It means using C# (we already mentioned the excellent compatibility of Visual Basic and C# — unlike Visual Basic, C# is developed and supported) to: 



1) add new features to the current desktop solution. In a split with modern .NET parts, the existing VB app is partially available on the web.  



2) plug in the web interface. It's a more comprehensive way to gain web presence as users will utilize web portals and pages. 



3) create a mobile app. Thanks to the API, parts of the Visual Basic system become available on mobile devices as well. All you need is qualified engineers who are able to connect the mobile app to the core of the existing system.



The extension approach to VB apps replacement is extremely suitable in such cases: 




the app doesn't have critical bugs or flaws; 



there’s a need to add some new functionality; 



rewrite or migration efforts aren’t paying off.






Advantages of the extension approach: 




it's the most cost-effective manner to transfer VB to the web app;



the upgrade can be done gradually without disrupting business processes; 



the promising opportunity to get an updated system shortly (within a couple of months);  



rapid payback due to feature-driven development.  






Cons of extension: 




due to the incompatibility of components, your application may be idle; 



it might not resolve some performance issues.






#2 Migrate with automation tools 



As an alternative to fragmented development, companies choose automation tools to migrate a VB app to a new environment. At first glance, it's a lucrative option to recreate the existing application with minimal time and costs. To that end, Microsoft officials introduced three proven tools: Microsoft Upgrade Wizard, Artinsoft VB Upgrade Companion, and VB Migration Partner tool, that arrived in 2008. They allow you to upgrade classic VB and VB.NET solutions to C#, Java, modern .NET, or cloud.  



With all the benefits of the following approach, the app would require additional work and consultation from experienced vendors. How to determine if it is right for your case to transfer a VB.NET app to a web app?  




the current app version works with bugs; 



app users complain about frequent errors and data loss; 



the number of app users are constantly growing; 



all your workflows are adapted to work purely on a PC.






Pros of automated migration: 




conduct the migration affordably and seamlessly; 



minimum disruptions during the process; 



extensive support and available documentation;  



automatic troubleshooting of VB vulnerabilities.






Cons of migration: 




you run the risk of inheriting a poorly scalable architecture; 



you need to hire a technical team who can fix any incompatibilities.

#3 Rewrite from scratch



As with every modernization project, you could always rewrite the app’s codebase from scratch to get rid of all legacy components, patterns, and tools. Thus, you must interpret the existing app’s logic using new technologies and languages.   



Companies try to avoid this method lamenting the abnormal level of complexity. These apprehensions are not groundless: a team must deal with dozens of databases, and rewriting efforts could last a while. However, in some cases, it's truly justified. Rewriting will suit you if:




the current version of the app is extremely outdated and buggy; 



crucial features are built into the code; 



you are not satisfied with the old application architecture (for example, it does not scale at all); 



you want to fully migrate to the web or mobile platform.

Pros of rewriting the VB.NET app: 




you will get a brand-new system that delivers an indisputable competitive advantage to your business; 



you will reap the benefit from the modern tech stack, thus spend fewer efforts and resources on maintenance; 



you will get the ability to grow your software at a fast pace on demand.






Cons of rewriting: 




it is an expensive and risky process, 70 percent of rewriting projects fail; 



you will need to verify that the new application complies with the old specifications.






Whatever of the available approaches you choose, it must reflect your business needs and fit in your budget. Make up your list of migration goals and check it with the mentioned above checkpoints.

With proper planning, you are likely to accomplish everything on time and within budget. Keep in mind that the process also requires retooling and rethinking and potentially adding or training staff. 



Once you come up with a plan outline, take into consideration refactoring – a procedure of the legacy code optimization without changing its external behavior. It’s needed to remove redundant code, as well as to reduce variables, dependencies, and connections to third-party tools. 




Possible pitfalls of using automation tools only.  




Automation tools, although specifically designed for VB code conversion, leave behind many gaps. Oftentimes, developers face unexpected issues when streamlining updated code. It means more resources are involved in the transition, implying additional time costs.   



Therefore, you should first decide what parts can be converted automatically, without risks, and what is better to do manually. 




Compatibility issues. 




Shifting data from one environment to another is also prone to data loss; some file formats become unreadable in the target system. Not all third-party tools used in the desktop version of the app are compatible with the web WinForms app.  



Probably, you couldn't avoid that kind of issue, and developers must spend some time ironing out all inconsistencies. But as a minimum, you can document all the important system requirements and test the new environment from the beginning.




Unqualified vendors. 




Unfortunately, only a few software development companies can provide the proper quality VB app migration services. It’s one of the dominant reasons why almost 74 percent of organizations failed to complete software modernization projects. 



Considering the peculiarities of Visual Basic, you should look among those who specialize in VB.NET software migration.

### Migrating from ASP.NET Webforms to ASP.NET MVC in 6 Steps

As much as ASP.NET Webforms is a tried-and-tested solution for building applications widely used across the markets up to this day, the technology has become clearly outdated. Many companies and entrepreneurs are still creating legacy products that fail to fulfill business goals, require extra maintenance, and are plain problematic to scale, support, and enhance.  



Fewer and fewer specialists able to work with such software remain in the market while their rates grow exponentially. Then, there is also outdated efficiency of performance, security, competitive edge, etc. What’s the solution?



Migrating Webforms to MVC may just be it. After all, the cost of maintaining legacy systems may not be worth covering at all.



Advantages of ASP.NET MVC Over ASP.NET Webforms



One of the main advantages of MVC over Webforms is a more novel nature which, presumably, spawns a stronger focus on the tool’s support by Microsoft (one of the major reasons why companies are moving to the cloud, too). However, it brings to the table a bunch of other technical benefits that a savvy MVC user can indulge in.



Less coding complexity



It may be easier to work with MVC for certain specialists for several reasons. First off, as opposed to an extensive web controls toolbox Webforms offer, MVC relies more on rich client-side controls carried out through JavaScript, offering much simpler controls as a whole. Secondly, if you have sufficient expertise, you can easily jump into the process and kick-off Webforms delivery as fast as possible. Lastly, it is easier to figure out coding issues when working with MVC due to the tool’s maturity and sturdy, active community.



More transparent and thorough control



MVC offers a distinctive separation between Model, View, and Controller layers, making your usual web design routine clearer and simpler to handle as a whole. This results in consistent designs created from the get-go. You also get full control over the rendered HTML and neat SoC (separation of concerns).



Faster response time



In whichever way the arguing may go, MVC is definitely faster in performance. One reason is that ViewState and PostBack events don’t hinder processes here. Then, there’s the ability to stuff whole DL and BAL logic inside an Action or Controller despite the forced separation of concerns mechanic. The mentioned separation of layers also plays a major part here, speeding things up. Thus, MVC Webforms are used for rapid web application development.

Fuller set of features



This is, first of all, due to MVC’s simple and widely ranging extensibility. Unlike Webforms, MVC is open-source. In particular, it can be easily, seamlessly integrated with client-side toolkits (rich UI tools) like jQuery and other JavaScript frameworks. And with web applications becoming “richer” by the day, this is a pretty relevant advantage over traditional Webforms. 







ASP.NET Issues with Webforms that MVC Solves



MVC is also considered among the most efficient legacy system modernization approaches because there are ASP.NET issues with Webforms that MVC solves. These further demonstrate why you should update Webforms to MVC and include the following.



Tightly-coupled pages



As opposed to Webforms, MVC is based on loosely coupled models where views and logic are kept in separate files and are, therefore, loosely coupled. This allows for more flexibility when handling web software structuring processes of development.



Heavy view state mechanism



Webforms is based on a strong data access model that results in cumbersome view state management, which leads to heavy web pages. This makes the creation of interactive apps unreasonable. In turn, MVC is on the lightweight side of the deal, allowing for the seamless creation of small-sized pages and providing all the proper capacities for developing dynamic, interactive apps.



Testing issues



Testing Webforms can become problematic due to traditional yet somewhat outdated testing approaches supported. Simply put, more thorough testing requires more professional effort. In turn, MVC supports and promotes test-driven development (TDD). Creating tests for pieces of web software here is a breeze, and it also means that you get an additional “continuous” layer of testing that is based on specific development assets.

With all that being said, the question stands – do you really need to upgrade from Webforms to MVC? It depends, and there is no definite answer – you may as well use other methods of upgrading legacy systems. For one thing, the app can be containerized and equipped with shared access for a distributed dev team, in which case you won’t have to rewrite any software code. 



While this is the case to be preferred by “neat” developers, you may also want to move on with the times and make your step towards converting ASP.NET webforms apps into MVC as the first is rumored to be no longer supported by ASP.NET in the nearest future. This resembles the trend of employing a multi-cloud strategy and other advantages of cloud computing by forward-looking companies.

6 Steps to Safely Migrate Webforms to MVC



Convinced yet? If you find the MVC benefits over Webforms attractive, the nature and capabilities of MVC fit your development principles and project specifics; it is high time you started using it for your web software creation purposes. There’s only one major thing to figure out. You can start creating forms from scratch via MVC, but what if you already have projects that need elaboration through a new approach based on the MVC pattern?  



This is where you can refactor existing apps by migrating their code from the respective codebehind files to a Web API controller (i.e., rewrite Webforms to MVC). Doing this and making the code work in the Web API controller requires some technical effort. But it should pay off well when all things are said and done. Thus, you can migrate Webforms to MVC step by step in the following way.



DISCLAIMER: The following is the all-around technical stuff that is best handled by an experienced professional. Trust only reputable resources with the info backed up by the proper expertise. The steps described below are based on the official guide by Microsoft, which serves as the perfect extension to the information given in this article.







Add Web API



The first thing you need to do is to start rewriting ASP.NET Webforms as MVC enables the use of the Web API in your ASP.NET project. For this, you must first install the NuGet Microsoft ASP.NET Web API package and toggle the desired programming language to Web after. Then, do the following:




Right-click and select - Add -> New Item -> Web API Controller Class;



Now that you have a created class, make sure its name ends with a string Controller;



Enable the method calling upon forms being posted back to the server - create a method named Post;



Create a class with properties whose names match the ID properties of the web forms’ TextBoxes to synchronize the post-back aspect.




Set a Webform routing rule



Now, you need to provide a routing rule that consists of a template specifying the rule-applicable URLs and controllers set to work out the underlying requests. It also points out values for the Web API that URLs hold. The routing rule is then added to the Application_Start event in the respective Global.asax file. In order to prevent collisions with other existing URLs, you should associate URLs with the Web API using the string api at the beginning of the code. 



This should help you assemble a generalized routing rule which is set into motion via statements for System.Web.Routing and System.Web.Http in the Global.asax and should look as follows:



RouteTable.Routes.MapHttpRoute(



  "API Default",



  "api/{controller}/{id}",



  new { id = RouteParameter.Optional })



);



Handle controller refactoring



Now, it is time to enable the Webform to post data to the route defined in the previous stage and back. You will have to revise the code tag the following way for this:



<form id="form1" runat="server" action="CustomerManagement"



   method="post" enctype="application/x-www-form-urlencoded">



This makes the action attribute of the form tag use route-specified URLs. And this is where a developer should start writing some code from scratch in the controller’s post method so that data manipulations in DTO could be carried out. The exact type of code and approach to setting up data processing is at the developer’s discretion. But once this is settled, some complex efforts come into play.



Consider reading this post to conduct refactoring of your system the right way. Legacy Code Refactoring: Tips, Steps, and Best Practices 



In particular:




All code that the ASPX code file was holding must be moved into the newly-defined controller method;



All server-side validation processes carried out by Validation controls must be added to the new project;



All code from the events fired by the page must be detached.




These are some complex tasks and issues (like MVC migration from Webforms ViewState issues) that should be handled by an experienced specialist (as the whole process of migration, actually). But after their successful completion, you will adopt the MVC pattern in terms of your web forms-driven software creation processes. After that, to finish up your complete change from Webforms to MVC you will only need to finish it up with some essential adjustments, including the following: 




Settle processing responsibility - equip web forms with labels for displaying the server-side processing results, for instance:Update Status: <asp:Label ID="Messages" runat="server" Text=""></asp:Label> 









Migrate events - replace ASP.NET server-side events with alternative JavaScript events that trigger postbacks to the server, invoking the fitting method on the service.









Add routes to specify methods - routes that specify controller methods (actions) by name (not by their HTTP type like in traditional Webforms).








What are the key .NET Core benefits over .NET Framework? Check in this guide. How to Convert .NET Framework to .NET Core: Migration Guide 



Settle processing responsibility



Webforms often combine user interaction and data processing, but in MVC, these roles are separated. To ensure a smooth transition, it's crucial to decide where the processing responsibility lies and redesign the workflows to align with the MVC architecture. This way, the application's functionality remains intact. For instance, if the controller returns an OK message, instead of redirecting users to a different page, you can add a label to display the result of server-side processing within the Microsoft Webform. This will enhance the user experience.



Migrate events



In Webforms, events play a significant role in handling user interactions. However, in MVC, the focus shifts towards using client-side scripting frameworks for handling these interactions. To adapt to this new approach, you may need to make adjustments in your code logic.



Here, you'll need to replace server-side events with client-side JavaScript handlers or make AJAX calls to appropriate MVC controller actions. You can also capture equivalent JavaScript events triggering the postback to the server and define call methods on your service that perform similar tasks as the server-side event code.



Add routes to specify methods



MVC architecture is designed to work with HTTP verbs (GET, POST, PUT, DELETE) to perform specific actions. But, most ASP.NET pages were not originally designed for HTTP verbs. Instead, a "transactional" approach is commonly used in defining the code.



To address this issue, you can use custom route attributes to specify the HTTP verb and other constraints for specific controller actions. These routes, called actions, significantly improve the clarity and maintainability of the application's routing logic, making it easier to tie page functionality to specific HTTP verbs without creating complex post methods that handle various processes.



Remember, all of these are work for a .NET and Visual Studio professional savvy enough to handle all the migration in ASP.NET MVC bits and ends. But in essence, that is all the stuff you must handle in order to move to MVC from Webforms for good.

### How to Migrate an Access Database to SQL Server in 6 Easy Steps

Growth in your business or organization brings an increase in the amount of information you store and manage. As your database size approaches the 2GB mark, which is the limit for MS Access, migrating to another Database Management System (DBMS) should be your immediate thought.



A few great alternative DBM systems present themselves: Oracle, PostgreSQL, SQL Azure Database, and SQL Server, being the most popular options on the market. This DBMS offers a lot in terms of the capability to store and retrieve data safely and accurately. However, since both MS Access and SQL Server have the same roots as Microsoft products, the migration to the SQL Server will be much easier.



This article provides a simple, step-by-step guide on how to migrate from MS Access to SQL Server. We’ll also walk you through some of the advantages of SQL Server over MS Access, and share valuable thoughts from database migration experts for your next migration projects. 



Why Do Companies Migrate from Access to SQL Server?



When it comes to managing enterprise-level data, MS Access doesn’t cut it for many reasons, including the fact that it’s 30 years too old. Microsoft even announced the retirement of MS Access from its online productivity suite in November 2017, before quietly changing its mind. Updates continued to appear – the latest version of Access in Office 365 was released in September 2020.



Even though MS Access is easier to learn, provides an easier and simple way of creating relational databases, and provides the possibility to use VBA to create fully-fledged data-centric applications, many companies are still migrating from MS Access to SQL Server, and so, over the years.



This is because of the numerous benefits that SQL Server and related DB systems have over MS Access. Microsoft Access is falling behind like FoxPro and COBOL and SQLBase.















To see the big picture, companies migrate Access to SQL Server for the following reasons:



Improved security



SQL Server is more secure than MS Access. It uses 128-bit encryption to provide a more secure way to store sensitive data like Social Security numbers, credit card numbers, and addresses. It also uses the same encryption algorithms to store user and application data in a remote place. 



Many IT pros and businesses simply won't tolerate Access because of its vulnerability to corruption. This means it’ll be harder to expand your business and find new business partners.



Increased availability 



With SQL Server, you can dynamically backup the database (incremental, or complete) while it's in use. The benefit? You do not have to force users to exit the database for every backup session.



As you might suspect, this feature is simply unavailable for MS Access owners. That means the business must pay for downtimes caused by DB inaccessibility for hours, days, or even weeks.



Better performance and scalability 



SQL Server is efficient because it performs queries in parallel, thus reducing memory use. The Server also allows multiple concurrent users and supports huge, terabyte-sized databases – compared to the 2GB limit for an Access database. Access is usually preferred for small, general tasks.



Superior database maintenance and integrity



With features like triggers, transaction logs, and repair processes, the SQL Server delivers better stability, integrity, and non-repudiation. 




The MS Access database can become corrupt, thus it's important to keep it up to date to get the best results. To check the current version of Microsoft you’re using, check the official blog. 




Server-based processing 



The client/server approach utilized by SQL Server enhances server processing speed by lowering network traffic and dealing efficiently with huge data volumes. 



Because Access is a file server, it lacks the capabilities of a database server.



Interoperability with Other DBMS



One problem with Microsoft Access is that it has its own file format that isn’t compatible with any other system. The .accdb format imposed by Microsoft is unique to MS Access alone. This is a huge block to integration and interaction with data types from other database systems.



SQL Server provides good interoperability with other database management systems, allowing developers to create safe and high-performance applications.



Is your issue rather linked to legacy systems built on MS Access? Learn how to integrate legacy systems efficiently, with our complete guide.



Getting Started: MS Access to SQL Server Migration





If you find the SQL Server benefits more attractive than MS Access, and the nature and capabilities of SQL meet your data processing needs, development priorities, and project specifics; it is high time you started upgrading a legacy database to the modern environment.





After that, you need to set up your migration environment. In this guide, we'll use the SQL Server Migration Assistant for Access (SSMA for Access), a recommended tool from Microsoft, but prepare to conduct manual fixes.





Below is the basic structure of the MS Access application. As a desktop DBMS, MS Access stores all of the components of the database system application within a single file. The DBMS software runs on a desktop computer. Data Entry forms, reports, and queries interact with the database tables stored within the same MS Access Database file.















To begin: 




Develop a data migration strategy for efficient outcomes.









Download and install SQL Server Migration Assistant for Access (SSMA for Access). SSMA for Access is installed using a Windows Installer-based wizard. We used the Windows installer 3.1 for this guide. 









To get the latest version of SSMA service and other prerequisites for installation, please see the official download page.









Get connectivity and sufficient permissions on the computer that hosts the target instance of your SQL server.

6 Steps to Migrate MS Access Database to SQL Server



We’ll follow 6 major steps to import the Access database to SQL Server, divided into two phases: the pre-migration and the post-migration phase. 



Before taking on the first step, it is advisable to involve an expert to complete some preparatory steps to ensure a smooth transition. These preliminary operations include adding table indexes and primary keys because every table in SQL Server must have a minimum of one index.





Every linked table must feature a primary key – if any update operation is to ever occur in the table. Plus, it is essential to verify primary and foreign key relationships by checking that they are associated with table fields featuring congruous data types and sizes.





Finally, it may help to analyze the whole system and to eliminate attachment columns. This is essential considering that SSMA does not change tables with attachment columns.





Ready to get started with the Access to SQL Server migration? Let's dive in!















Step 1: Assessment



Use SSMA to review your database objects and the database itself. To do this, open SSMA for Access and click on a file then new project. Then enter a project name and a location to save your project. Select an SQL Server migration target from the drop-down list, and click OK.



Right-click the database you want to assess in the Access Metadata Explorer and then select ‘Create Report‘. You are advised to review the report so as to identify any errors and understand the conversion statistics.

Step 2: Validate the data types



You’re required to change your data types or validate the default data types. To change your data types, select ‘Project settings’ on the tools menu and then select the mapping table tab. Select the table in Access Metadata Explorer to change its mapping type.



Step 3: Convert



Converting database objects takes the object definitions from the Access metadata, converts them into equivalent Transact-SQL (T-SQL) syntax, and then loads this information into the project. 



To accomplish this, select the ‘Connect to SQL Server‘ query and fill up the connection information. In your Access Metadata Explorer, right-click the database and choose ‘Convert Schema’. 



Compare and review the converted objects to the original objects when the conversion is complete to detect potential flaws and resolve them using the recommendations. Select ‘Review results’ in the output window, and then review the mistakes in the Error List pane.



Finally, select ‘Save Project’ from the File menu. This step allows you to assess the source and target schemas offline and make any necessary changes before publishing the schema to SQL Server.



Step 4: Migrate



Finally, it's time to move the Access database to SQL Server. The first thing to do here is to publish the schema we converted in the previous step to the SQL Server. In SQL Server Metadata Explorer, right-click the database and select ‘Synchronise with Database’ to publish the schema.



Now, examine the relationship between your source project and your target. To migrate the data, perform a right-click on the database or object you want to migrate in Access Metadata Explorer and select ‘migrate data.’



Alternatively, you can go to the ‘Data Migrate’ tab. Check the box next to the database name to migrate data for the entire database. To migrate some particular tables, Open the database, expand Tables, and then click on the check boxes next to the tables to transfer data from individual tables. Uncheck the boxes corresponding to tables you want to omit. Once the Access database migration to SQL Server is complete, do well to view the data migration report.



But we’re not quite done yet!

Post Migration Phase



The post-migration step is critical for resolving data accuracy and functionality concerns, ensuring completeness, and dealing with workload performance difficulties.



Step 5: Perform test



After the upgrade process is complete, certain tests are to be performed for verification and validation, including:




Developing a  validation test, which involves creating validation queries to run against both the source and the target databases.









Setting up a test environment that will contain a copy of the source database and the target database.









Running validation tests against the source and the target, and then analyzing the results.









Running performance tests against the source and the target, and then analyzing and comparing the results.

You may encounter certain issues after migration, often related to Queries, Date and time, Data Types, Attachments, Hyperlinks, etc.



Step 6: Optimize performance



Choosing whether to use local or remote queries is one of the effective approaches to improve performance with your new back-end SQL Server. Here are some of the things you should consider doing:




For quickest access, run short, read-only queries on the client.



Use the server to run extensive read/write queries to make use of the extra processing capacity.



Filters and aggregation might help you reduce network traffic by transferring only the data you need.



Minimize loading data in a form or report.



Consider using local tables for data that rarely changes.




There it is… our ultimate guide on how to convert Access database to SQL efficiently.

### What is Wrong with IdentityServer4 and What Alternatives to Choose?

On October 1, 2020 Dominick Baier, one of the IdentityServer founders, published an article that confused the IT community. IdentityServer was rebranded and changed its monetization policy starting in November 2022.



Back then, the IdentityServer team transformed the product from a hobby project to a real business. The reasons for such a solution were the following: 




The IdentityServer became too difficult to manage and support due to its increased popularity. 



The project didn’t cover the cost of running and maintaining the core project and codebase. 




So, what’s in store for software projects which rely heavily on IdentityServer? And what does it have to do with Duende Software?



What is IdentityServer?



An identity server is the control center of the IT infrastructure - it defines who connects to what IT resources within the organization. To clarify all things out imagine that all interaction scenarios between users and applications must be protected from unauthorized use. Such protection assumes Identity Management - the process of identifying, authenticating, and authorizing individuals or groups of people to have access to applications, systems or networks by associating user rights and restrictions with established identities.  



IdentityServer (IS) is an open-source OpenID Connect and OAuth 2.0 framework for ASP.NET Core that’s especially favored in the dev community. Being officially certified, IS gives people a starting point for building a security token service. Due to the broad community support, IdentityServer4 examples are easy to find in GitHub.  As for the latest IS’s version, IdentityServer4 (IS4) became the de facto standard for .NET-based token services, the implementation of IdentityServer4 in .NET Core 3 in practice. Now it serves as a central identity server authentication repository for thousands of apps that allows creating a robust authentication & authorization system within the projects. So, let’s move on to its most remarkable features.







Key features of IdentityServer4



IdentityServer4 provides the following features for applications: 



1. Authentication as a Service



IS provides centralized login for all applications (web, native, mobile, services). IS is an officially certified implementation of OpenID Connect. 



2. SSO



IS provides Single Sign-on/Sign-out over multiple application types. 



3. Access control for APIs



IS issues access tokens for APIs for the following client types: server to server, web applications, SPAs and native/mobile applications. 



4. Federation Gateway



IS supports external identity providers like Azure Active Directory, Google, Facebook. 



5. Customization



Since IdentityServer is a framework, not a boxed product or a SaaS, it can be customized. Users can write code to adapt the system to fit their scenarios. 



6. Open Source



IdentityServer is open source, well documented, and supported by the extensive community.



What is Wrong with IdentityServer4: 3 Rights of Use Changes? 



If you are actively using IdentityServer4, this is the information of utmost importance. Starting in November 2022, the service underwent drastic changes such as:



Rebranding



IdentityServer was rebranded as Duende IdentityServer. IdentityServer4 support lasted until the end of life of .NET Core 3.1, which was in November 2022. In that way, Duende server provides new documentation for the fifth service version. 



Pricing



The officials said that IS4 remains free for free open-source work, development, and testing. For commercial scenarios it will require annual payments. Plus, as a bonus, there is a 50% discount licensing for startups and non-profit organizations. The company offers a lucrative deal for charities and small companies – a free plan. 



Licensing



Up to November 2022, IdentityServer used the permissive Apache 2 license that allows building commercial products on top of it. Starting November 2022, IdentityServer remains open source, but works with a dual license: RPL and commercial.




RPL is a reciprocal public IdentityServer4 license. It keeps Duende IdentityServer free for free open source work.



Commercial license applies for all other use cases – provided that it is used in a commercial scenario.



Software. A Duende IdentityServer vs IdentityServer4 comparison shows that the Duende IdentityServer will contain all new feature work and will target .NET Core 3.1 and .NET 5. Everything in the IdentityModel organization will stay unchanged.




.NET 5 offers exciting opportunities for every project. Learn how to migrate from .NET Framework to .NET Core here How to Convert .NET Framework to .NET Core: Migration Guide 



Problems of IdentityServer’s End-Users



How can such a solution influence the end-users of the IdentityServer? Is there a real problem or it’s just a routine announcement for IS users? Let’s sort the whole thing out. 



Cost increase



The first and obvious aspect of the new IdentityServer policy is cost increase. It will cost at least $1,500 per year for typical commercial scenarios. IdentityServer is an OAuth framework, so the tariffication metric is clients but not users. The cheapest Starter edition allows for 5 clients without reference to the number of users. Each additional client will cost $300. 







And this is how much you overpay for the legacy software in your organization The Cost of Maintaining Legacy Systems: How Much You Overpay 



Architectural solutions



Per-client tariffication of the IdentityServer can force businesses to implement single-client applications instead of multi-client solutions. It can be critical for small businesses with limited resources. For the current users who have already implemented a multiple-client architecture (multiple sub-domains), there are no ways to reduce the cost – even if each client includes only one or several users.  



For new applications, the developers will have to search for the best architectural solution – weighing all pros and cons of single-client websites and applications with multiple subdomains. 



Support



Starting in November 2022, no free support for IS4 has been provided. The commercial support can be overwhelming for a non-profit developer. As for commercial licenses, Duende provides Standard developer support in Starter and Business editions. Standard support includes public documentation, samples, and an issue tracker.  



And Duende provides Priority developer support in the Enterprise edition that starts from $12,000 annually. Users will get public documentation, samples, issue tracker, and incident response SLA (Service Level Agreement) for that price. Hope that it will be reliable enough to meet all the business needs.



Microsoft templates



Microsoft has bundled IdentityServer4 into the templates in the first place. So, using those templates for commercial purposes, you’ll have to pay for IdentityServer. If you want to migrate IdentityServer4 to Duende, note that there are no proposals or free plans from Microsoft related to Duende IdentityServer.



IdentityServer is frequently used in .NET projects.

The forced changes associated with the growth of time and financial costs are uncomfortable for any business. If your application uses IdentityServer4, one way or another, you must choose a new operating scenario. 



Option 1. Continue using the “all-in” IdentityServer 



If the business needs all the functionality of IS, including flexibility, unlimited number of clients, and support, it will cost $12,000 annually. Developers who do care about identity management and work with IS4 in a daily job environment, are OK with spending company money on it. 



Pros: 




Continue using the tool that ideally fits the product needs. 



No need to spend time and money on searching for IdentityServer4 alternatives. 



Getting all the Duende IS additional features:

Unlimited clients. 



Unlimited issuers - any number of logical token services running in production at any number of unique URLs.  



Automatic key management. 



BFF (Backend for Frontend) hosting library. 



Dynamic authentication providers. 



Resource isolation. 



Priority developer support. 






Cons: 




Cost: $12,000 annually. 




If the business doesn’t need the Enterprise edition, which is more suitable for ERP upgrade, it can choose one of the alternatives IS pricing. There’re starter and business editions of the following service having equally useful features, but with some restrictions.

Option 2. Use IdentityServer for free 



After November 2022, developers can keep using IS4, but without free bug fixes and security updates. In case of a critical problem, developers can fork IS4 and patch it themselves with the help of the IdentityServer team on Github. 



It may even happen that a client can still use Duende (IS successor) for free. In any case, it’s worth checking the conditions of the free licensing. 



Duende IdentityServer is free in the mentioned cases, though with some limitations. Besides, following the original discussion, Dominick Baier emphasizes that they are ready for dialogue with each specific customer.

Option 3. Don’t use IdentityServer: IdentityServer4 vs other equivalents 



If the business doesn’t need all the IS features, the customer application has “easy” identity management scenarios, or the processes aren’t heavily dependent on IS4. Developers and businesses can choose alternative products from other vendors or develop their own one. 



The IT community is still trying to figure out the best IdentityServer4 alternatives and get over the shock. But be as it may, there’re decent variants. One of the approaches is to distinguish library-type and product-type solutions for identity management. 



By its origin and purpose, IdentityServer itself is a library-type solution. The library-type solution can fit most under the following conditions: 




You need free and open-source software. 



You need to manage all the data yourself due to regulations or privacy requirements. 



You need flexibility during the authentication flow, for example, a custom workflow for finding or merging user accounts. 



You have enough time, skills, and resources to run it yourself. 




In contrast, a product-type is suitable for the clients that meet certain criteria: 




The price is not a determining factor. 



You need to save time and human resources on implementation and operation. 



The product contains just enough settings for your use case. The lack of flexibility is OK or at least not critical. 



The product gives even more out-of-the box features required for your project. 




IdentityServer Alternatives



Let us take an in-depth look at the alternatives to IdentityServer, including the following services: OpenIddict, Keycloak, Azure Active Directory B2C, and other solutions.











OpenIddict vs IdentityServer4



One of the IdentityServer4 alternatives proposed by the IT community is OpenIddict. Like IdentityServer, it’s a .NET library-type solution that works with client authentication and token issuing, but not user authentication, and allows implementing custom login flows. OpenIddict operates under the Apache 2 license, uses OAuth and OpenID Connect protocols, and is supported by the GitHub community. 



However, compared to IdentityServer, OpenIddict is even more “bare metal” with fewer features straight away. For instance, in OpenIddict, you must provide extra code for the token endpoint before you get a working client credential flow.



Keycloak vs IdentityServer4



Another IS alternative, Keycloak, is an open-source product-type solution. It operates under the Apache 2 license, but unlike IS and OpenIdDict, it is Java-based and has no such flexibility as libraries. For example, it doesn’t support custom grant types and custom login flows for users. 



Unlike IdentityServer and OpenIddict, Keycloak is a ready-to-run product, so you can launch in minutes using Docker. 



Microsoft Azure Active Directory B2C vs IdentityServer4



Azure Active Directory B2C can be a solution if there is no need for flexibility and you are hosting customer identities in a SaaS. It’s a Microsoft product running only in the Azure cloud. AAD B2C pricing is user-based, and is free for 50,000 monthly active users (MAUs). 



Compared to IdentityServer, Azure AD B2C is a cloud-based identity and access management service with pre-built templates, offering scalable infrastructure and various functionalities, including user authentication and authorization. 



Other alternatives



These are some of the other best alternatives to IS:




Rippling 




Rippling is an integrated platform that simplifies and optimizes and automates a business’s human resources, payroll, and IT management. It also streamlines operations and enhances efficiency for businesses by providing a comprehensive solution for managing their workforce while ensuring the safety of applications from cyber threats.




Okta 




Okta is a cloud-based platform designed to simplify and strengthen identity and access management for businesses. It provides comprehensive tools and functionalities to ensure secure user authentication, seamless single sign-on, and efficient user management. 




JumpCloud 




JumpCloud is a cloud-based directory platform that provides a comprehensive IAM solution, allowing businesses to manage user identities, access controls, and device management from a centralized platform. It streamlines authentication processes, enhances security and compliance, and simplifies system management.




Active Directory Federation Service 




For on-premises, Microsoft has an ADFS (Active Directory Federation Service) alternative. ADFS is a solution for SSO and Internet authentication. It follows a process similar (but not equal) to OAuth, uses some open standards (HTTPS, SAML), but is Microsoft-specific and requires Internet Information Services (IIS), which only run on Windows servers.

### How to Convert .NET Framework to .NET Core: Migration Guide

.NET Core gained instant popularity among software developers when Microsoft launched it for the first time on June 27, 2016. Today, 55% of developers prefer it to .NET Framework because it makes it easier to build software that can be deployed across multiple environments.



However, as with any technology change, moving an existing app from .NET Framework to .NET Core can be pretty daunting. And while there are many reasons why this may be beneficial, you should thoroughly understand what’s involved in migration before you take the plunge.



In this post, we’ll discuss how to convert .NET Framework to .NET Core and what you should keep in mind during the process.



Why Is Migration from .NET Framework to .NET Core Relevant?



The .NET Framework has been the default environment for Windows desktop, web, and server applications for over 19 years. It’s a great environment, but not perfect. The biggest problem with .NET Framework-based projects is that they are tied to Windows. That’s fine if you only want to run your application on Windows machines, but it inherently limits the options if you want to run your app on Linux or macOS.



While it cannot be denied that there are advantages in using .NET Framework, there are quite a few limitations. 



For example:




There is limited support for object-relational (OR) in .NET since it comes with only Entity Framework.









Microsoft controls the future development of the .NET Framework due to its vendor lock-in.









Compared to C, C++, .NET Framework has low performance and is not suitable for high-end applications.









Even though .NET Core is a .NET Framework successor, the transition to .NET Core is complex.




The last point is especially important as .NET Core is considered the future of .NET development. In fact, according to the official announcement from Microsoft, new applications should be built on .NET Core starting from 2019. As of 2024, the newest .NET releases are .NET 8 which was officially released in November 2023. Waiting for .NET 9 this autumn!















In What Cases .NET Framework to .NET Core Migration Makes Sense



Should you migrate from .NET Framework to .NET Core? When it comes to migrating to .NET Core, it’s not a case of if you should, but when. Of course, there are still many applications that run smoothly on the .NET Framework, and in some cases have been doing so for years. So why would you want to mess with that?



There are quite a few reasons why you would want to migrate your current application infrastructure to .NET Core. The most important reasons, though, are:



When you’re looking for performance improvements



Because of its modular structure, .NET Core makes it easier to access specific features without having to use the entire framework. This allows developers to implement only those features they need, resulting in faster performance. Therefore, if you are trying to improve performance, then migrating your code to .NET Core should be among your strategic steps.



When you want to benefit from cross-platform development



Another great reason to migrate your application to .NET Core is that it will now run on Linux or macOS. This opens up a whole new range of possibilities of where you can run your application. You can run it on Linux servers or even on a Raspberry Pi!



When you want to get an open-source codebase



The best thing about .NET Core being open source is that anyone can contribute to its development, which results in seamless bug fixes and swift, constant deployment of feature upgrades. This means that if you find an issue with any part of the framework, you can easily fix it in-house, or hire a professional to get the job done. 



When you strive for simpler package management 



NuGet has been a great thing for .NET developers, but it can be complicated at times. Packages can have dependencies on other packages, and if those packages have different versions of the same libraries. In other words, they might not work together. Core has a new package manager that makes this easier.



While there is no urgent need to port .NET Framework to .NET Core, it looks as though the latter is the framework of choice for the future. So, if you are thinking of moving, and you don’t have a qualified in-house team, be sure to look for a company that offers desktop migration services, legacy software updates and cloud services. This is the only way to guarantee a seamless transfer.







The comparison table: Difference between .NET Framework and .NET Core











As you can see from the table above, .NET Framework is a mature, stable, and reliable technology that businesses can leverage for a wide variety of applications. There are, however, some cases where using the .NET Framework can be a better option. This is especially true if your application fully relies on libraries and packages that are not supported by .NET Core, your business needs are already met, and your resources are limited.



Check the detailed .NET Framework overview from our team. Assessing .NET Framework: Advantages, Disadvantages, and Support Status 



How to Migrate to .NET Core from .NET Framework - 5 Key Steps



Converting .NET Framework to .NET Core is an important decision that can positively impact your application’s performance and maintenance in many ways. In this section, you will learn the key steps to making the move.



First, it is important to point out that there are two approaches to migrating your project – automatic and manual.



How to not get lost in the modernization approaches to legacy solutions in 2024 and on? Read our guide Legacy System Modernization Approaches: Practical Advice on Dealing with Outdated Software 



Migrating Automatically



Migrate using .NET Upgrade Assistant



To change from .NET Framework to .NET Core automatically, you can use the .NET Upgrade Assistant. This tool analyzes an existing .NET Framework application and provides recommendations for migrating its projects to target .NET Core. 



The Upgrade Assistant also tracks compatibility issues as it transforms the application. The report generated by the Upgrade Assistant can be used as a starting point for migrating an application from .NET Framework to .NET Core.



Migrating Manually



Here is a step-by-step process on how to migrate from .NET Framework to .NET Core manually: 















1. Analyze Project Dependencies



Before you start with the migration process, you need to analyze the system background, your code and dependencies. Microsoft has provided .NET Portability Analyzer, a tool to analyze your application dependencies and project references. This tool also helps you to identify the APIs that are not available in .NET Сore.



The tool is available as a Visual Studio extension and NuGet package. 



In case you discover NuGet dependencies that are not compatible with .NET Core, there are some approaches you can take to proceed with the migration: 




Contact developers and ask them for support. Remember that .NET Core is open-source and developers are volunteers, which is why you should be mindful of their time and efforts;



Visit nuget.org and search for a package that fulfills similar functionality as the one you are using now;



If possible, try to write a code that will accomplish the same tasks as the package itself. 



New versions and new features keep being released; therefore, you can simply wait until the day of the release and not use some app functionality until then. Contact the .NET team to let them know which library you would like to use.




2. Migrate from ASP.NET MVC



Since this migration is the easiest step, many companies choose to start with it. The good news is that the process is relatively quick and easy thanks to the comprehensive Microsoft guidance.



The steps for this are:




The first step is to create a new ASP.NET project using the type that suits your project best: ASP.NET Core Web API, ASP.NET Core Web App, or even ASP.NET Core Empty if you are starting from scratch. Make sure that your Target Framework is ".NET 5".



Ensure that your Global.asax.cs code is up-to-date. .NET 5 requires migration of any custom logic to the startup class.



Transfer all existing controllers and classes to the new project structure.



Update your API controller classes. They should derive from Microsoft.AspNetCore.Mvc.ControllerBase. It may be a good idea to create your own ApiControllerBase class that derives from ControllerBase and is decorated with the [ApiController] attribute. Microsoft.AspNetCore.Mvc.Controller provides support for MVC Views, so such controllers are typically derived from this class.



Fix all Nuget and reference errors. Namespaces have changed in .NET 5, so you will probably need to adjust your using statements.



If you use Handlers, convert them to .NET Middleware.



Move web.config settings to appsettings.json.



Get rid of old projects and any unnecessary files, such as Global.asax, app.config, and packages.config




3. Migrate from WebForms



One major drawback of .NET Core is that WebForms are not supported. This is why instead of calling it a migration, moving WebForms is called porting from .NET Framework to .NET Core.





This process is quite complex. You can choose to rewrite your application from scratch rather than trying to port the legacy code. This can result in a more reliable and secure application. However, this move requires significant time and effort.



Alternatively, you can gradually migrate the system page by page to .NET Core.





You can upgrade a small part of the system, test it and see if everything works correctly, and then start upgrading another part. This gives you more flexibility if you don't want or cannot stop all work on your application at the same time. You will need to run two core libraries at the same time for this though.

4. Move Your Project File



You can migrate your old project to the Core project using the ‘dotnet migrate; command, which migrates the project.json and any other files that are required by the web application.



The dotnet migrate command will not change your code in any way. It will just update your project file to use the new SDK-style project format (i.e. csproj).



5. Test Run your Application on .NET Core



Once you've migrated your application it should run on any supported operating system. The final step in migrating your application should be to test running your current application on .NET Core. Run your application on .NET and if it works, congratulations! You are ready to go.

To sum up, it is important to point out here that some apps cannot be migrated through automation tools because they are large and clunky, especially enterprise systems. This is where a legacy software expert like ModLogix comes in.



We can work with you to migrate your application to the latest .NET Core seamlessly and easily so that you too can begin to enjoy the many benefits of the .NET Core framework.

.NET Framework to .NET Core Migration Challenges to Keep in Mind



Although upgrading .NET Framework to .NET Core comes with a ton of business benefits, such as improved performance and deployment flexibility, there are some challenges that you need to keep in mind before and during implementation of the project. For instance, you need to pay attention to: 



API Compatibility



Although prevalently used libraries support both frameworks or provide compatible alternatives, your team might still find it challenging to integrate APIs that are not supported in .NET Core. You can solve this challenge by using Microsoft’s API Portability Analyzer (APA) to identify potential issues during migration and remediate them.



Platform Dependencies



Platform dependency is another big challenge for .NET Famework to .NET Core migration projects. Platform-specific dependencies in applications built by .NET framework may vary, but prevalent ones include third-party components or system-level integration points such as Windows Registry access or COM interop calls.



One way of solving this challenge is by doing away with the dependencies altogether, especially if they are unnecessary for core functionality. However, if you cannot replace or do away with certain dependencies, you might want to explore conditional compilation techniques along with build configurations, specifically customized for each target platform. 



Code Refactoring 



Upgrading to .NET Core from .NET Framework comes with new behavior patterns, causing differences between the APIs of the two frameworks. For example, .NET Core might lack certain classes or methods, prompting you to rewrite the sections of the code that apply to them. In other words, refactoring the existing code is necessary. 



Refactoring challenges can be addressed in several ways, including adoption of modern coding practices like async/await patterns or dependency injection. You can also use .NET Core’s exceptional handling technique to refactor the codebase while preserving key functionalities. 



Testing Strategy 



Testing is one of the most overlooked .NET Framework to .NET Core migration challenges. Usually, a typical migration project requires extensive testing to validate the application’s functionality and stability when deployed across different platforms. In addition to leveraging the existing unit tests, developers might also need to conduct compatibility testing, especially if they are going to identify and remediate platform-specific issues emanating from the migration process. 



You can circumvent this challenge by creating comprehensive test suites for every support runtime environment and operating system. Alternatively, you can leverage specialized testing frameworks that offer extensive cross-platform support, such as NUnit or xUnit.



Technologies That are Not Supported by .NET Core



There are quite a few technologies that are not supported by .NET Core, so you probably will have trouble with them during migration. Pay close attention to the main components and tools: 




Application Domains




Application domains were used to provide isolation between different applications running in the same process. Since processes provide isolation between different applications in .NET Core; application domains are not supported. The new AssemblyLoadContext class is recommended for dynamically loading assemblies.




Remoting




.NET Remoting is a .NET technology that enables applications to communicate with each other. It basically allows remote components to communicate across application domains.



Although remoting is a powerful technology and can be leveraged in many use-cases, it's not available as a part of .NET Core, because as we already know, AppDomains are not a part of the .NET Core. As an alternative to remoting, you can use web services or make use of other inter-process communication technologies such as gRPC instead.




Code Access Security (CAS)




Code access security (CAS) was a security feature of .NET Framework-based applications. It was based on code groups that had a set of permissions associated with them. In .NET Core, CAS isn't supported by default. However, you can still specify permissions for assemblies using the following options.



When is it time to migrate a desktop Visual Basic app to the modern .NET technology? 3 Approaches for Safety Migrating a VB.NET App to a Web App 




Use role-based security to secure your application. 



Use resource-based security for finer-grained control over your application. 



You can also use an external authorization service that performs centralized authorization for your application. 





LINQ2SQL




LINQ to SQL is a component of the .NET Framework that provides a run-time infrastructure for managing relational data as objects.



LINQ to SQL fully supports transactions, views, and stored procedures. Because LINQ2SQL is a .NET Framework component, .NET Core does not support it at all. You will have to use Entity Framework Core to get similar functionality.















How to Prepare Your System for .NET Framework to .NET Core Migration



As you may already know, .NET Core is a popular open-source, cross-platform, and high-performance framework for developing web applications. However, .NET Framework to .NET Core migration is not as easy as it seems. Still, you can make the move without too much trouble if you follow this 3 step process.











1. Implement the Model Binder



When you migrate a desktop app to .NET Core, the way you handle form data may need to change. The model binder is a powerful component that can automatically map data from HTTP requests to action method parameters.



To simplify the process of .NET to .NET Core migration, use model binding.



2. Leverage on APIs and Client-Side Development



You should use more APIs to build applications and be more client-oriented. Also, if you want to make your apps more accessible, build them on Angular or React — newer frameworks that are less dependent on WebForms and easier to port.



3. Create .NET Standard Libraries



Another crucial process of migrating an existing codebase to .NET Core is by creating .NET standard libraries. This will allow you to know if the same code can be used in both a .NET Framework application and a .NET Core application. It also allows you to start migrating the code without having to redeploy the entire application.

### How to Convert Classic ASP to ASP.NET

Approximately 1,237,353 web services still rely on Classic ASP for their backend operations. However, the modern digital landscape demands speed, security, and flexibility—areas where Classic ASP falls short. The solution is migrating to ASP.NET, a modern and scalable platform with robust features and extensive community support.



In this guide, we will walk you through converting your Classic ASP application to ASP.NET, covering the benefits of the transition, potential challenges, and best practices for a successful migration.



Let's begin!



Benefits of Converting Classic ASP to ASP.NET



Let's start with the benefits of why you should convert classic ASP to the more current ASP.NET.



Architecture



Classic ASP scripting can result in messy, difficult-to-maintain code. ASP.NET employs the Model-View-Controller (MVC) framework, encouraging better code architecture and maintenance.



Development Tools and Ecosystem



ASP.NET, based on the robust .NET Framework, provides a complete set of tools, notably Visual Studio. With its sophisticated debugging features, extensive API support, and a huge library of pre-built components (NuGet packages), ASP.NET speeds up development, simplifies debugging, and provides faster access to standard functions.



Programming Model



ASP.NET supports multiple programming languages like C#, F#, and VB.NET, unlike Classic ASP's procedural programming model. This allows developers to create cleaner, more maintainable code.



Performance and Scalability



Classic ASP can slow down under heavy traffic, impacting performance and user experience. In contrast, ASP.NET excels in this area. Its JIT compilation and the .NET Framework enable it to effectively manage high user loads, ensuring your web app remains responsive even during peak traffic periods, providing reassuring scalability for your web application.



Cloud Support



Classic ASP has limited cloud computing compatibility. ASP.NET, however, easily integrates with modern cloud platforms like Microsoft Azure, facilitating easier deployment, improved project management, and automatic scaling based on demand, leading to cost-effective infrastructure use.



Compatibility and Cross-Platform Support



Classic ASP is tied to Internet Information Services (IIS) on Windows servers. NET code, however, supports multiple web servers across Windows, Linux, and macOS. This cross-platform compatibility lowers hosting costs and expands deployment possibilities, transforming ASP.NET into a versatile and future-proof alternative for modern web development.



Migrating from Classic ASP to ASP.NET



Now that you know why ASP.NET is better, let’s discuss how to convert classic ASP to ASP.NET, ensuring a smooth transition and a robust foundation for your web application.



Pre-migration Preparation



Start by conducting a comprehensive legacy software audit to ensure a smooth transition to ASP.NET. This means assessing your Classic ASP application to understand its functionalities, dependencies, code structure, and potential migration hurdles. 



Next, establish a secure testing environment that mirrors your production environment. This allows for safe testing of migrated components without impacting live functionality. You also want to consider implementing caching mechanisms to reduce database load and enhance application performance.



Don't forget to verify that your development environment has all the necessary ASP.NET tools and libraries to facilitate efficient development.



Migration Roadmap



Once you've analyzed your existing ASP environment, it's time to migrate, and this means creating an app modernization roadmap! Define what parts (entire app or specific features) need modernization to boost performance and security. Make a complete list of everything in your app to avoid missing anything. Back up your data thoroughly to minimize downtime and protect information. 



The migration involves converting the legacy code, moving data, and integrating with ASP.NET. If your team lacks experience, consider seeking expert help. After migration, iron out any compatibility wrinkles, fine-tune the code, and perform data migration testing to ensure that everything functions flawlessly.



Post-migration Routine



After successfully migrating classic ASP, focus on these post-migration activities:



Bug Fixing and Continuous Testing



Thoroughly test the migrated application to identify and fix any bugs or functionality issues, ensuring a stable, bug-free, and seamless user experience.



Systematic Updates and Maintenance



Establish a process for applying updates, security patches, and ongoing maintenance within ASP.NET. This keeps the application secure, performant, and aligned with evolving technologies.



Educating Users



Provide training or documentation on any changes in functionality or user interface resulting from the migration. This minimizes user disruption and ensures a smooth transition for all stakeholders.

Migration Challenges



No migration is without challenges. Here are potential issues you may encounter migrating your application.



Getting to Grips with the Old App’s Architecture



Classic ASP applications, especially those built years ago, can have convoluted architectures. Understanding the application's logic and the ASP code structure can be time-consuming, potentially delaying the migration timeline.



Migration Cost



Migrating a complete application is a complex undertaking. You have to factor in a lot of expenses—developer labor costs, license fees for new technologies, and the requirement for adequate testing infrastructure. Navigating these barriers requires careful budgeting and resource allocation.



Peculiar Classic ASP/ASP.NET Issues



ASP.NET and classic ASP are fundamentally different. The migration process may reveal incompatibilities or require code rewrites to fix these differences. Unexpected technological difficulties may also increase complexity and lengthen the migration period.



Lack of Specialists



Finding developers proficient in both techstacks can be a challenge. In fact, the world over, there is a persistent shortage of skilled workers, with the IT sector experiencing a substantial 76% talent shortage as of 2023. It may be necessary to invest in training for existing developers. You may also have to hire external developers, which might affect migration project timeframes and costs.



Standard Migration-Related Risks



Data loss, unexpected functionality breakdowns, and compatibility problems are potential pitfalls during any major migration. A well-defined ASP migration plan with rigorous testing procedures is essential to mitigate these risks and ensure a smooth transition.

The cloud has revolutionized how businesses manage their IT infrastructure, so much so that 94% of enterprises now use cloud services in some capacity. However, despite this shift, on-premise systems remain an essential resource to many businesses.



But what is the difference between cloud and on premise, and which should you use in your organization? Read on as we compare cloud based vs on premise systems, covering the benefits and risks of each approach to help you decide which best suits your organization's needs.



Cloud vs. On Premise



The debate on cloud computing vs on premise is not new, but it is an important debate that revolves around key factors that affect organizational strategy and operational efficiency. 



Cloud computing services offer convenient access to computing resources and services on demand, enabling businesses to scale dynamically and pay based on usage. This reduces the need for in-house IT teams to maintain and upgrade infrastructure. 



On the other hand, on-premise systems provide precise control over infrastructure and data — a critical factor in industries with strict regulatory requirements. Additionally, on-premise systems are commonly used by companies that still rely on legacy systems which is almost two-thirds of Fortune 500 companies. This is because their legacy systems may not work with the cloud computing environment.



What is On-Premise?



On-premises solutions or on-prem refers to the IT infrastructure and software within an organization's physical office and maintained on-site. This method means that the organization will buy, set up, and manage both the software and the underlying hardware of its IT infrastructure locally.



What is Cloud Computing?



Cloud computing is a revolutionary concept that delivers IT infrastructure — servers, storage, databases, networking, software, and analytics—over the Internet. This approach allows enterprises to immediately access resources from a cloud service provider while only paying for what they use.The takeaway from this on premise vs cloud computing comparison is: Businesses own and manage everything on-prem, while cloud offers pay-per-use rental.



Key Differences of On Premise vs Cloud



Understanding the key differences between on premise vs cloud systems will make it easy to make the best choice for your organization. Let’s look at these distinctions.



Deployment



One key difference when comparing on premise vs cloud is how the system is deployed. The on-premise setup is hosted in-house (on-site), which requires upfront costs and in-house expertise. With the cloud, however, there is no need to invest in physical hardware because the cloud service vendor provides all the necessary resources.



Cost



Another factor in any cloud vs on premise comparison is cost. On-premise infrastructure demands a substantial initial capital investment (CapEx) for hardware, software licenses, maintenance, IT staff, energy consumption, and other operational expenses. On average, businesses shell out $6,785 monthly to maintain their on-premises infrastructure, compared to $2,085 for cloud services. 



Cloud solutions typically operate on a pay-as-you-go model where businesses only pay for the resources they utilize. This flexibility often results in a lower total cost of ownership (TCO), which drives cloud adoption for 34% of enterprises.



Control



Control level is also a key factor when comparing cloud vs on premise systems. With on-prem, businesses have complete control over every aspect of their infrastructure—critical when dealing with sensitive information. In contrast, using cloud services means giving up some power to the vendor, who oversees data storage and security. Cloud companies typically provide comprehensive protection and disaster recovery to ensure data safety and industry compliance.



Security



Security differs when comparing cloud versus on premise solutions. On-premises systems require organizations to invest in and maintain internal security measures like firewalls and encryption, which can be resource-intensive to maintain effectively. Cloud providers, on the other hand, manage security from their end. Not only do they engage the top cybersecurity professionals, but they also provide advanced security methods like multi-factor authentication and intrusion detection to protect stored data properly within their systems.



Compliance



Compliance management is a key factor in the cloud vs on premise debate. On-premise solutions offer direct control to ensure compliance, but can be time-consuming and expensive. Cloud service providers offer compliant solutions, reducing management burden.

Private Cloud vs. On-Prem vs. Hybrid Cloud



Organizations are moving beyond the traditional debate of on-premise vs cloud deployments. A new option, the hybrid cloud, offers a blend of both approaches. This environment combines private/on premise and cloud services, allowing data and applications to be transferred across them. A private cloud is a computing environment exclusively dedicated to a single organization.



According to Statista, over 74% of organizations use hybrid cloud solutions to meet their IT needs. These companies can keep important and sensitive workloads in a private cloud or on-premise system for increased security and regulatory compliance while using the public cloud for less sensitive operations or to meet demand surges. This flexibility improves resource allocation while taking advantage of the scalability and cost-effectiveness of public cloud services.

The wave of digital transformation has been sweeping across industries in recent years, from healthcare to retail, aviation, and even non-profits. But the insurance sector has been slow to catch up. 



Today, approximately 80% of global insurers still depend on outdated legacy systems to manage core processes. These systems are severely inefficient, leading to longer claim processing times, poor customer satisfaction, and increased costs. To alleviate these issues, they end up pouring large sums of money to maintain the systems. In fact, research shows that insurers allocate at least 70% of their IT budgets toward infrastructure support, which is a significant waste of resources.



One possible solution would be system modernization through automation. By embracing automation technologies, insurers can reduce expenses, and align more effectively with contemporary customer expectations and regulatory requirements. 



Self-Service Legacy Systems Automation for Business Users



Automating self-service capabilities within legacy IT systems empowers business users to access and manage data without IT support. This process involves automating operations for carriers, making it easier to manage tasks like client and claims management, policy administration, and insurance accounting. Also, it increases processing efficiency and reduces the number of urgent support tickets IT staff need to handle. 



According to the 2024 Global State of IT Automation Report, about 88% of businesses surveyed offer self-service IT automation to end-users. By decreasing reliance on specialized IT staff, this self-service automation allows insurers to focus on strategic initiatives, helping them manage routine inquiries and transactions while freeing up resources for transformative projects.



Schedule Workflows Across Legacy, Modern, and Third-Party Technologies



Insurance companies often work in isolated departments, making it tricky to coordinate tasks that involve different teams and systems. They usually use a mix of legacy and modern technology, along with third-party systems. 



Automating workflows across these technologies ensures seamless integration and data flow. This makes handling compliance reports, underwriting, and reserves easier. Studies suggest that companies using automated workflows are 60% more likely to boost efficiency. Automation ensures updates, data transfers, and system checks happen smoothly, even among disparate systems.

Gartner reports that cloud spending will reach $678.8 billion in 2024, and McKinsey estimates that $8 out of every $10 IT spend will go to cloud services. 



Cloud computing comes in various forms: public clouds (like AWS, Azure, and Google Cloud), private clouds, hybrid clouds, and multi-cloud setups. Public clouds let you share resources and pay only for what you use. Private clouds give you control and privacy. Hybrid clouds mix the benefits of both for more flexibility and security. Multi-cloud strategies involve using different providers to lower risks and increase benefits.



Cloud Migration Types



When deciding on-prem to cloud migration, businesses can choose from several approaches. These include: 



Rehosting: Moving without Modification



Also known as the "lift-and-shift" or "forklift migration," rehosting involves transferring applications, data, schema, and workloads from on-premises to a cloud infrastructure without any alterations. 



Although this on-prem to cloud migration method is relatively straightforward, it restricts the functionality of your apps because they haven't been adapted to run natively in the cloud. This approach is ideal for selected on-premises workloads with minimal impact or as a preliminary migration strategy for organizations new to cloud computing.



Refactoring: Reworking for Cloud Optimization



Refactoring, often termed "rip and replace" or "redesign," is a more intricate process. It involves rewriting and restructuring the architecture of apps,  data, and schemas before or after the transition, with post-migration being more common. Its key advantage is the opportunity to redesign apps from the ground up with the cloud in mind, leveraging the latest features offered by cloud service providers (CSPs). 



While initial on-premise to cloud costs may be higher, cloud tools will run more effectively in the long run. If you're planning to move a significant number of apps and workloads off-premises, refactoring may be the optimal choice.



Replatforming: Adjusting for Platform Compatibility



Replatforming involves making adjustments to applications to ensure compatibility with the target cloud platform while retaining most of the existing architecture. It strikes a balance between the simplicity of rehosting and the optimization potential of refactoring, making it suitable for organizations seeking a middle ground.



Often called "move and improve" or "revise," this approach is commonly used, for instance, when altering how an app interacts with its database. Replatforming is applicable in scenarios such as migrating from on-premises infrastructure to Infrastructure as a Service (IaaS) or transitioning to a Platform as a Service (PaaS) offering.



Re-purchasing: Adopting New Cloud Solutions



In the re-purchasing strategy, organizations move data from existing on-premises applications to cloud-based Software as a Service (SaaS) solutions offered by third parties. This approach is ideal for businesses looking to discard in-house software, especially if they have been compromised or is considered outdated. Enterprises can seamlessly transition to modern and efficient solutions using this strategy.



Retiring: Phasing Out Unnecessary Components



Retiring involves ceasing the use of specific applications or workloads, and decommissioning them as they reach the end of their life cycle or become obsolete. This strategy simplifies the migration from on premise to cloud process by eliminating unnecessary complexity and reducing the overall footprint in the cloud. It is an effective way to declutter and streamline operations, aligning the technology stack with the current business needs.



Re-visiting: Re-evaluating Strategies as Needed



Re-visiting involves periodically reassessing on premise to cloud migration strategies and adjusting them as needed based on evolving business requirements, technological advancements, or lessons learned from previous migrations. This iterative approach ensures that organizations can adapt to changing circumstances and optimize their cloud deployments over time.



Advantages of Shifting to the Cloud



Here are the key benefits of making the upgrade to cloud architecture and cloud migration services.



Enhanced Accessibility for Users



On premises to cloud migration ensures that your critical applications and data are accessible anytime, anywhere. Whether your team members are working from the office, home, or on the go, they can easily retrieve the resources they need with just an internet connection. 



Quick access to public cloud resources increases flexibility and guarantees that company personnel are no longer restricted by physical location when it comes to job performance. 



Improved Performance and Flexibility



One of the primary benefits of migrating from on premise to cloud is the improvement in performance and flexibility. Cloud service providers offer state-of-the-art infrastructure and technologies, ensuring that your application run smoothly and efficiently.



With data centers strategically located across the globe, cloud providers minimize latency and optimize performance for users worldwide. The cloud also gives you more flexibility, letting you easily adjust resources depending on how much you need, handling busy times, and using resources efficiently.



Scalability and Elasticity Benefits



Scalability and elasticity are perhaps the crown jewels of cloud computing. The cloud allows you to scale resources dynamically in real-time, ensuring that you only pay for what you use. Whether it's handling increased user traffic during a product launch or scaling down during off-peak periods, the cloud provides the flexibility to adjust without significant infrastructure investments. 



Financial Savings Through Efficiency



Cost savings are a major driving force behind data migration from on premise to cloud, and for good reason. By shifting from a capital expenditure model to a pay-as-you-go model, businesses can significantly reduce upfront costs and ongoing expenses associated with hardware maintenance, upgrades, and energy consumption. Notably, Accenture discovered that transferring workloads to the public cloud can save 30-40% in Total Cost of Ownership (TCO). Similarly, in an OpsRamp survey, 94% of IT professionals said it helped reduce startup costs.



Heightened Security and Regulatory Compliance



For C-Suite executives, security is the primary advantage of cloud computing, with 60% prioritizing it over cost savings, scalability, ease of maintenance, and speed — according to an Oracle report, Security in the Age of AI Report. 



This preference stems from major cloud providers' significant investments in cutting-edge security measures. These measures include encryption, identity and access management, and threat detection, all aimed at safeguarding sensitive data from cyber threats.



Challenges in Cloud Migration



Moving on-premises workloads to the cloud requires careful planning to avoid potential challenges. With the right approach and partners, these obstacles can be overcome.



Deficient Cloud Migration Strategies



A common pitfall in onprem to cloud migration is the absence of a robust strategy. Rushing into migration without a well-defined plan can lead to inefficiencies, cost overruns, and disruptions to business operations. It's important to thoroughly assess your current infrastructure, identify goals and objectives, and devise a detailed roadmap outlining the migration process.



Effective Cost Management



On-premises to cloud migration can incur significant expenses, particularly if not managed carefully. Without proper cost management practices in place, businesses risk exceeding their budget and experiencing financial strain. To address this challenge, organizations should closely monitor cloud usage, optimize resource allocation, and leverage cost-effective solutions offered by cloud providers. 



Potential Lock-In with Service Providers



While migrating from on prem to cloud offers flexibility and scalability, it's essential to be mindful of the potential for vendor lock-in. Relying heavily on a single cloud provider may limit your ability to switch providers in the future or leverage alternative solutions. To mitigate this risk, consider adopting a multi-cloud or hybrid cloud approach, distributing workloads across multiple providers to maintain flexibility and avoid dependence on any single vendor.



Ensuring Data Security and Adherence to Regulations



Entrusting your data to a third-party cloud provider requires robust security measures to safeguard against potential threats and breaches. Prioritize encryption, access controls, and authentication mechanisms to protect data both in transit and at rest. Additionally, ensure compliance with relevant regulations and industry standards, such as GDPR, HIPAA, or PCI DSS, to maintain data integrity and confidentiality. Regular audits and assessments can help verify compliance and identify areas for improvement.



Step-by-Step Approach to Cloud Migration




Designating a Migration Architecture




Appointing a Migration Architect is the first crucial step. This individual oversees the on premise to cloud migration plan, from planning to execution, ensuring alignment with business goals and performance objectives.

Determining Integration Levels with Cloud Services




Decide on the depth of integration with cloud services. Shallow integration, or "lift-and-shift," involves moving everything without significant changes. Alternatively, deep integration requires modifications for optimal cloud performance, providing long-term benefits. Choose an integration level that aligns with your business objectives and resources.




Evaluating Single or Multi-Cloud Strategies




When moving on premise to cloud, you have the option to choose between a single-cloud or multi-cloud strategy. Single cloud offers simplicity in management but may limit your options. On the other hand, multi-cloud provides more flexibility and resilience but requires additional effort in management. Again, evaluate your business needs and goals to determine the most suitable approach for your cloud migration.




Set Cloud KPIs and Performance Baselines




Establish Key Performance Indicators (KPIs) and performance baselines before migration. Clearly define what you aim to improve, whether it's website loading speed or overall system responsiveness. These metrics will serve as benchmarks for success, allowing you to track progress and ensure that your on premise to cloud migration meets your performance expectations.




Prioritizing Migration Components for Efficiency




Not all applications and data need to be migrated at once. Prioritize migration components based on their importance and urgency for day-to-day operations. Start with critical systems or data that can provide immediate benefits in the cloud. This ensures a focused and efficient on prem to cloud migration process and minimizes disruption to business operations and resource optimization.




Implementing Refactoring Techniques as Needed




Refactoring involves optimizing existing applications for the cloud environment. This may include rewriting code, restructuring architecture, or adopting cloud-native services. Implementing refactoring techniques helps improve performance, scalability, and cost-effectiveness in the cloud. It's essential to assess which applications would benefit most from refactoring and prioritize them accordingly.




Creating a Comprehensive Data Migration Strategy




A well-defined data on premise to cloud migration strategy mitigates risks and ensures a secure transfer to the cloud. This should encompass inventorying data, assessing dependencies, classifying data based on importance and sensitivity, and selecting suitable cloud services.Make sure to choose the right migration tools and techniques cloud while minimizing downtime and data loss. In addition, ensures data cleansing, transformation, encryption, and compliance with relevant regulations.  




Executing the Transition to Cloud Production Environments




Once the groundwork is laid, it's time to execute the transition to cloud production environments. This involves moving workloads, applications, and data to the cloud while minimizing disruption to business operations. Monitor the transition process closely and address any issues promptly to ensure a successful on prem to cloud migration.

Evolve or risk becoming obsolete. That is the reality facing businesses in today's dynamic tech landscape, especially those who still rely on outdated legacy software solutions.



Once the cornerstone of organizational efficiency, legacy systems have become stumbling blocks to progress, making modernization necessary today. According to Forrester, 70-90% of these systems will require overhauling within the next five years, underscoring the urgency of this transformation.



In this article, we'll discuss ten compelling benefits of legacy system modernization and application modernization trends, highlighting why modernizing legacy systems is not just a choice but an essential pursuit for enhanced efficiency, competitiveness, and successful digital transformation. Let's begin.



What is a Legacy System?



A legacy system refers to outdated software or technology still in use within an organization, often due to its critical role in operations. Although once cutting-edge, these systems have become barriers to technological advancement due to their inability to integrate with newer technologies, leading to operational inefficiencies and security risks. 



Modernizing legacy systems is essential for organizations to remain competitive and efficient in today's digital landscape. Here are more reasons why you should consider modernizing your legacy systems



1. Costly Maintenance



As legacy software ages, they become expensive due to ongoing maintenance. For example, if your system relies on obsolete technologies, you will consistently spend money fixing issues to prevent frequent downtime. The codebase will be complex, and finding skilled developers who can understand and work with it will be challenging.



Consequently, your company may allocate a significant portion of its IT budget. Approximately 75% will go towards sustaining the software and paying huge salaries to developers proficient in the outdated programming language. But by modernizing the software, you can significantly reduce these expenses and make maintenance more cost-effective.



2. Poor Security



Protecting against security breaches is another reason to modernize legacy systems. Legacy systems were developed in a different era and lack contemporary security standards. This obsolete security architecture can make your system vulnerable.



Cyberattacks can exploit these vulnerabilities, leading to data breaches, system downtime, and legal consequences. In 2023 alone, the cost of these threats reached a staggering USD 4.45 million. Modernizing your software will bolster your digital defenses, enabling you to address vulnerabilities and remain current with the latest security features.



3. Incompatible with Modern Tech



The lack of interoperability is another compelling reason to upgrade your legacy system. Some legacy systems struggle to integrate with modern technology, causing operational inefficiencies, higher costs, and missed opportunities to harness the advantages of modern technology.



Imagine you have a system designed long before cloud computing, mobile apps, data analytics, and IoT became essential. Now, you want to expand your business by integrating these modern technologies. The problem? Your old software isn't compatible with these modern technologies. Updating your software to modern standards will empower it to connect seamlessly with today's state-of-the-art solutions. This enhances efficiency and facilitates adaptation to market dynamics, providing a competitive edge.



4. Poor Mobility



Many legacy applications are device-dependent, making it challenging for users to access and interact with the system on modern devices like smartphones and tablets. This limits productivity and remote work opportunities and is another reason to update legacy software. 



For example, if your sales team relies on outdated software, it will be difficult, if not impossible, for them to perform certain critical tasks while on the go. However, modernizing your software will make it work on any device, making it more flexible and user-friendly. Your team can use mobile devices to access info, work better, discover opportunities, and serve customers faster.



A recent study shows that 65% of salespeople at firms with mobile CRM achieve their sales quotas, compared to only 22% at companies without it. This data underscores the importance of legacy system modernization.



5. Regulatory Compliance Issues



Data privacy, security, and reporting regulations continually evolve, and legacy software may not meet these latest regulatory and compliance standards. So, why update the legacy software? Not doing so can lead to serious regulatory compliance issues and legal challenges, especially in healthcare, finance, and data security industries.



For instance, if your organization handles sensitive customer data and relies on a legacy CRM, you may unknowingly violate one or more regulations, potentially subjecting your company to substantial fines and reputation damage. Modernizing your software allows you to proactively adapt to new regulations, safeguarding your business and maintaining stakeholder trust.



6. Poor User Experience



Today's users want applications that are modern, easy to use, and look good. But old systems tend to be clunky. Their outdated user interfaces fall short in the area of user experience, and this can lead to user frustration, reduced productivity, and customer attrition.



If your organization relies on outdated technology, your customers or employees will likely express frustration with your software's cumbersome interface and sluggish performance. According to a recent survey, antiquated technology significantly hampers business productivity, with over 57% of employees stating that their current software diminishes efficiency. An additional 49% complain that dated software is stressful to use. These problems answer the ‘why modernize legacy applications’ question.



Modernizing your software can revolutionize the user experience, making it more intuitive, responsive, and visually pleasing, ultimately leading to heightened user satisfaction, productivity, and engagement.



7. Technical Debt



Over time, legacy software accrues what is known as technical debt. This is the cost of maintaining outdated, inefficient, poorly designed code and systems. You will incur this debt if your software is obsolete, riddled with workarounds, and rely on patches to keep it functional. 



This technical debt not only inflates maintenance costs but also constraints your ability to adapt to evolving business requirements. Re-architecting, reengineering, or refactoring the code will deliver a more stable and sustainable system, addressing the technical debt issue. The benefit from the legacy software modernization here is the long-term health of your software, reducing ongoing expenses and enhancing adaptability.



8. Competitive Advantage



Legacy systems are typically harder to adapt and customize to changing business needs. This inflexibility can hinder a company's ability to respond quickly to market changes, causing them to fall behind more adaptable competitors.



Imagine being in the retail industry, where your competitors deploy modern, cloud-based point-of-sale systems featuring real-time inventory tracking, personalized customer experiences, and online ordering. If you persist with outdated, on-premises software, you risk losing customers to your more nimble competitors. The role of legacy system modernization here is to put you at the forefront of the competition, enabling you to introduce new features, meet customer expectations, and efficiently seize market opportunities.



9. Scalability and Business Continuity



Outdated software can limit your business's ability to scale so that you cannot meet increasing demands effectively. For example, if you have a legacy enterprise resource planning (ERP) system, it may not be able to handle increased user loads or new business requirements. In this scenario, if your business experiences growth, the legacy system becomes a bottleneck, leading to inefficiencies and potentially hindering business continuity. 



So why update the legacy system? You do this to ensure your software can flexibly scale up or down as necessary. Modernization empowers you to sustain business operations, whether you're facing a high surge in demand or even in the face of unforeseen challenges like pandemics or natural disasters, by enabling remote work and providing secure access to critical systems.



10. Enhance Efficiency and Productivity



One of the most important reasons for legacy application modernization is the need to enhance efficiency and productivity in business. 



For example, if you rely on obsolete, standalone software systems for tasks such as inventory management, production planning, and order tracking. You will likely experience lots of data duplication, errors, and operational inefficiencies, ultimately hampering productivity.



Modernizing your software entails integrating these systems into a unified, streamlined solution. This results in seamless data sharing, streamlined workflows, improved decision-making, automation, and real-time collaboration. The result is improved overall efficiency and productivity, leading to higher-quality results.



As you can see, whether you use one outdated application or more, there are many reasons to modernize legacy software. Apart from the satisfaction of moving your critical applications into the 21st century, you'll also be positioning your business to navigate the dynamic tech landscape adeptly.

4 Key Approaches for COBOL Modernization



COBOL has been a mainstay in the business world for decades, but its outdated nature and limited talent pool pose significant risks for organizations. To address this issue, there are four critical approaches to COBOL software modernization that businesses can consider:



Rewriting



Rewriting is a radical approach to COBOL modernization that involves the total rewrite of COBOL applications using modern languages like Java, C#, or .NET. COBOL's business rules and logic must be analyzed and meticulously replicated in the chosen language. This approach is ideal when maintaining existing COBOL code becomes complex, lacks flexibility, or no longer suits current business needs. It offers the advantage of embracing modern technologies and practices. However, it's resource-intensive and time-consuming.



Another reason to rewrite COBOL is when you are dealing with COBOL V5 migration or enterprise COBOL V6 migration. Those versions are quite different from COBOL migrations, so they may require more profound code changes.



Refactoring



Refactoring focuses on improving the internal structure of the COBOL code without altering its external behavior. This can involve restructuring the program, optimizing routines, or removing redundant code sections. For example, COBOL's PERFORM statements might be optimized, and standardized data structures like COPYBOOKS could be implemented across programs to enhance maintainability.



Of course, it's a safer approach to deal with COBOL, but it may be lengthy and ultimately turn into a more comprehensive migration.



Integration



Complex, interconnected COBOL systems can opt for integration as a modernization route. This approach requires the development of APIs (such as RESTful, SOAP, or GraphQL) to expose COBOL functionality to other systems and applications.



Integration is ideal when leveraging existing COBOL logic alongside modern technologies like cloud services, mobile apps, or web frameworks is necessary. It offers flexibility and scalability, enabling the adoption of modern practices without disrupting existing COBOL systems.



Replatforming



In the replatforming approach, the COBOL application is adapted to run in a new environment. This might require changes to data access methods or the introduction of new middleware. For instance, COBOL programs might be modified using embedded SQL to interface directly with modern relational databases. If the original system utilized CICS (Customer Information Control System) for transaction management, alternatives like Micro Focus Enterprise Server might be adopted.

As we already said, COBOL migration can be complex, so divide the migration path into achievable milestones for expected outcomes.



Legacy System Assessment: Assessing your existing COBOL system to know exactly what you are getting into is crucial. For example, many COBOL systems use VSAM files for data storage, which function like key-value storage and differ from modern SQL databases. Also, in most cases, data is often encoded in EBCDIC, an older character encoding standard incompatible with ASCII. Then, there will likely be GDG (Generation Data Group) files for version control.



Modernization Approach: Choose the most suitable COBOL application modernization approach based on your legacy system's complexity and specific needs. Consider whether you'll rewrite, refactor, integrate, or re-platform your COBOL applications.




We recommend applying for a phased migration to modernize the app piece-by-piece instead of a big-bang approach. That way, you'll avoid unnecessary business disruptions and prioritize critical features and modules.




Testing: According to IBM, a large percentage of COBOL migration has data-related issues, which makes testing one of the crucial parts. Include unit, functional, performance, security, and usability testing to ensure your software supports business goals and meets migration objectives.



Backup and Contingency Plans: Ensure you have a reliable backup of your existing system and data, allowing you to revert quickly if issues arise. Contingency plans should outline steps to address potential setbacks and minimize downtime. These plans are essential regardless of whether you're undergoing a COBOL to Java migration, COBOL to C# migration, or COBOL to .NET migration.



Long-Term Sustainability: Consider the long-term sustainability of your modernized system. Ensure it can accommodate future growth, evolving technology trends, and changing business requirements.




To Sum Up



COBOL is still very popular today in 2023, as it was decades ago. However, many organizations want to modernize their COBOL applications in line with the changing digital landscape.



Whether you're considering a COBOL to .NET migration, COBOL to Java migration, or migration from COBOL to Python, modernization can be a complex and challenging process.

Whether you’re upgrading system functionality, speed, or overall performance, an ERP solution is a mission-critical system, and the process requires thorough planning and meticulous execution. Here are 9 important steps in upgrading an ERP system: 







1. Align Business and Strategic Goals 



Liaise with all executives in the organization, from the CEO to CFO to ensure that the planned ERP upgrade aligns with business and strategic goals. Additionally, you’ll need the approval of these people for budgeting and overhaul of certain business functions or operations. 



2. Define Your Scope and Budget



The next step involves defining the scope and the budget of the project. This means establishing the specific parts, modules, or features of the ERP that require an upgrade. In terms of budgeting, factors to consider include hardware and software costs, licensing, consultation fees, and contingency. 



3. Identify the Pain Points and Benchmark 



Which exact business points are you trying to solve by upgrading the ERP? Is it poor data integration, a financial loss, or lower user adoption? Whatever it is, note down and benchmark extensively to determine if it will be solved with an upgrade.  



4. Talk to the Frontline Users 



After identifying the business points, talk to the frontline users to understand the routine business processes that will be impacted by the upgrade. That way, you can ensure these processes are uninterrupted post-deployment. 



5. Choose your Approach and Modernization Partner



The choice of approach and modernization partner depend on a range of factors, including the nature and complexity of the project. If you want to implement all changes simultaneously, you might want to use a big bang approach, or phased approach for iterative changes. Also, you’ll need to decide whether you’ll work with the ERP provider, an inhouse team, or third-party modernization company. 



6. Create a Feasible Implementation Plan 



An ERP upgrade is a significant change that doesn’t only take your time and money but also impacts the core operations of your organization. With that in mind, create a feasible implementation plan beyond the vendor’s “perfect-world” scenario and factor in all your intricate business needs. 



7. Handle Data Mapping 



While some vendors may provide data mapping tools, the onus of implementation lies with you. This is because the vendor focuses more on the data within their system and not your organization’s – so prepare to handle it all the way. 



8. Educate and Train Users 



Educate and train all levels of users within the organization on how to use certain functions and the benefits of leveraging the upgraded version. For instance, tell them how it simplifies their work. 



9. Validate Results and Evaluate Performance

### Guide to Cloud Migration Strategy Process

Organizations are increasingly looking for better ways of streamlining operations, increasing flexibility, reducing costs, and leapfrogging the competition. For many business leaders, the solution lies in cloud computing. According to Gartner, the cloud provides a highly strategic platform for achieving end-to-end digital transformation goals and the adoption of emerging disruptive technologies like artificial intelligence. 



Consequently, global end-user spending on public cloud services is poised to grow by 21.7% and reach $597.3 billion by the end of 2023.  



However, adopting a cloud-first strategy comes with its share of challenges as well – the first one being migration. Whether you’re a local startup or a multinational organization, the process of cloud migration strategy can be complex and requires thorough planning and execution from the word start. It’s important to note that a cloud migration strategy outlines meticulous steps and considerations involved in moving to the cloud to ensure that the process is efficient and stays within the budget. So, how do you go about it? 



In this cloud migration strategy guide, we highlight everything you need to know about successfully moving your business applications and data from on-premises servers to the cloud. We also include practical advice based on real-world experience in the approach to cloud migration, as well as the typical challenges of a cloud migration strategy. Keep reading to learn more. 



What is a Cloud Migration Strategy? 



A cloud migration strategy is a framework describing how you’ll move your system, either wholly or partially, to the cloud. Migration-to-cloud strategies should analyze which business elements to migrate, what order, which tools to use, and which new functionality to add later on.

Key Successful Cloud Migration Strategy Requirements



The general requirements of a cloud migration strategy include the following: 




Definition of Business Needs and Requirements 




By pointing out the exact reason for switching to the cloud, such as the need to optimize costs or scale effortlessly, you can align the migration strategy with the overall organization's strategic direction in terms of goals and ambitions. 




Assessment and Analysis of Existing Infrastructure 




When assessing this requirement, it will help if you assess a range of factors, including compatibility with the edge computing environment and future dependencies between different components. 




Evaluation of Security Requirements 




Evaluate your security posture and consider other strategies that can help ensure the safe migration of business data and applications to the cloud. 




Selection of an Appropriate Deployment Model 




The next requirement involves choosing the right deployment model that suits your business requirements — a private, public, or hybrid cloud. 




Ensuring Data Integrity During Transfer




Conduct in-depth research on network bandwidth capabilities, both at source and target environments, especially when voluminous data sets are involved. Most importantly, determine which technique guarantees the utmost data integrity, whether the use of direct connections, secure file transfer protocols (SFTP), or virtual private networks (VPN). This step is of paramount importance while migrating hybrid cloud mainframe systems.




Change Management Plan and Communication 




Create an effective change management plan that extends to comprehensive training programs for your team. 



Designing and implementing an enterprise cloud migration strategy should involve the collaboration and input of all key stakeholders within the organization.



Why You Need a Cloud Migration Strategy



Cloud migration is a complex process. The more complex the migration, the greater the risks of failure. Why do cloud migration projects fail so often? Let’s take a look at the hard facts:



A recent study by HIS Markit, which surveyed 350 enterprises around the globe, found that 74% of respondents had moved at least one application back from the cloud into their own infrastructure. The top drivers for this decision were performance and security issues (52%), followed by the temporary nature of cloud deployments (40%) and regulatory issues (21%).



Another study by Accenture asked respondents to identify the greatest barriers to leveraging the advantages of the cloud. The four barriers mentioned most frequently were security and compliance risk (65%), the complexity of business and organizational change (55%), legacy infrastructure and/or application sprawl (44%), and lack of cloud skills within the organization (42%).




“We believe these conclusions echo what we’ve been hearing from customers for years — that cloud migration is a difficult, confusing process that must be approached in a holistic fashion. The successful organizations are the ones that take the time to plan, evaluate their options, and adopt continuous-learning feedback processes.”
JOE KINSELLA, CLOUDHEALTH TECHNOLOGIES



The success of your cloud migration efforts lies in your ability to set clear goals and benchmarks, create a timeline, and anticipate potential challenges. In other words, you’ll need an all-embracing migration-to-cloud strategy. Here are the importance and reasons for building a cloud migration plan for the future of business.




Scalability and flexibility: With edge computing, your organization can effortlessly scale up or reduce resource allocation based on the foregoing demand fluctuations. This translates to increased scalability and flexibility, void of physical constraints. 



Data accessibility and collaboration: With the successful planning and execution of all elements of a cloud migration strategy, your team can access important business information from any location or device for data-driven decision-making. 



Downtime mitigation: Having a robust plan helps minimize downtime during the digital transformation process by highlighting proper testing procedures and viable redundancy measures.

3 Main Cloud Migration Strategies: Benefits and Challenges



Here are some of the most popular strategies and techniques for system migration, with their corresponding benefits and challenges. 







1. Rehosting



Rehosting is also referred to as a “lift-and-shift” approach within which a business “lifts” an existing system from its current environment and “shifts” it to a new cloud-based infrastructure.





Benefits



Rehosting is a quick way to take a system to the cloud with little disruption to business operations, as there’s no change to the app’s architecture and little or no change to the app’s code.





Challenges



Rehosting is only feasible if the destination cloud can support the application as-is. Migrating the app without addressing its existing challenges can lead to added costs and performance issues in the future.









2. Replatforming



Replatforming is a variant of lift-and-shift migration. Comparing rehost vs replatform, replatforming involves making small changes to the app code to optimize it for the cloud.





Benefits



Replatforming allows businesses to optimize their apps for cloud-native capabilities. Businesses can start small, test things out, and scale without investing many resources in the short term.





Challenges



Businesses should make extra efforts to prevent uncontrolled growth in the scope of the project, which can turn a replatforming project into a costly refactoring one.









3. Technical Migration



With a technical migration approach, the app remains “as is,” while the OS and the database are upgraded to the cloud. 





Benefits



Technical migration allows businesses to leverage the cloud’s benefits without rewriting apps from scratch.





Challenges



Migrating databases to the cloud entails spending significant time and cost to analyze, plan, and execute each step of the migration, with close attention to data integrity across databases.









4. Application Migration



Application migration involves transforming the application alongside the OS and the database. Generally, this approach uses one of the three following scenarios:



New system implementation



With new system implementation, the applications are either rebuilt to leverage the cloud or replaced with new off-the-shelf applications.





Benefits



For businesses upgrading from a legacy infrastructure with complicated workflows and heavily customized code, implementing a new system can be the “fresh start” needed to eliminate problems with the previous architecture.



In contrast to modernizing old systems, the organization can choose a new suite of applications to go into, regardless of their current environment or vendor.





Challenges



New system implementation is an expensive, time-consuming process. Businesses need to define every aspect of the new system, including which of the existing functions to keep and which new ones to add.



For large, complex projects, implementing a new system can take years of effort and require various specific skills and governance, sometimes up to fundamentally changing the way that a company operates. Moreover, should the company need to maintain access to the existing data, this may create an added task for data migration, presenting a new set of challenges.









System conversion



This approach implies upgrading and reengineering each of the three individual layers: applications, databases, and the OS. 





Benefits



System conversion is an effective approach for organizations looking to bring their business processes to a new platform and add extensive new features while keeping their existing customizations.





Challenges



The implementation’s success will depend on the organization’s ability to replicate its workflows, which requires thorough knowledge of the company’s current infrastructure.









Landscape transformation



This approach implies selective data migration to a new target system. This enables businesses to selectively redesign aspects of their systems while maintaining important customizations and solutions.





Benefits



Consolidating application landscapes can significantly accelerate the transformation and reduce downtime compared to multiple projects. Selective data transformation provides a phased approach to migration, reducing the risk and effort of moving to the target system significantly.





Challenges



One of the big challenges in landscape transformation is automating and optimizing transformation processes across many large infrastructure instances. This calls for a thorough analysis and testing of all data elements in the transformation.

What to Include in Your Cloud Migration Strategy



Generally, cloud migration involves three major phases: pre-migration, migration, and post-migration. Here are some cloud migration strategy best practices during these phases. 



Things to Do Before Cloud Migration



Consider the goals you want to achieve. Perform a comprehensive functional and technical assessment of your system and then create a step-by-step plan for your migration project. During this phase, you should carefully consider the resources, costs, timelines, and potential risks of cloud computing for the project. Each virtual machine incurs an ongoing cost to add to your budget.



Weigh your options strategically: sometimes, buying a new on-premise server may be a more cost-efficient solution than migrating and managing applications. Make allowance for the extra resources spent on training and reengineering activities involved in the migration.



Things to Do During Cloud Migration



Start with setting up a working development environment for your project. Ensure that all components, including third-party solutions, are compatible with the new environment. Make sure to thoroughly verify that your deployment is working as expected. If possible, run services in parallel for some time to make sure everything is working properly before you make the final move. 



Monitoring the security and performance of your system is a must-do for any cloud migration process. Keep an eye out for any performance issues during the migration, when it’s easier to take a step back and make the necessary corrections. A simple “lift-and-shift” approach is rarely the end of the cloud migration journey.



Things to Do After Cloud Migration



There are various post requirements for the cloud migration strategy. First, make sure that everything works as intended, with all the data in the right place and format. Secondly, ensure that the data is secure and protected. Remember that you’ll need to use and maintain your system flawlessly at all times. This will require you to train your IT team or hire professionals to support the infrastructure, monitor essential KPIs, and respond to issues promptly.







7 Steps of a Successful Migration Process




Evaluation. Assess the potential benefits, costs, and risks of cloud computing for your business;



Planning. Decide on the cloud migration tools, skills, and techniques required to migrate to a cloud computing environment;

How to Get Cloud Migration Strategy Right: Dos and Don'ts



Below, let's take a close look at the most common mistakes in cloud migration and share tips on how to avoid cloud migration pitfalls at each step of the process. Paying attention to these factors will help you realize the full benefits of a cloud migration strategy. Here is the checklist: 



Don’t overlook business analysis. The very first question to answer in any cloud migration strategy is: “What value do we expect to achieve by moving to the cloud?”



Do take a good 360-degree look at your document databases, code, servers, storage, and your team’s expertise to identify cloud solutions that will work best for your business-specific goals.




“Just picking up an application and moving it to the cloud sounds easy — but why are you doing that?”
Dave Bartoletti, Forrester



Don't neglect app analysis before migration. Not all applications are cloud-friendly. Some apps are better fit to work on-premise, while others are better suited to run on private or hybrid clouds than on a public cloud. Some may need minor tweaking, while others may require refactoring to adapt to the cloud environment.



Do take time to scrutinize your apps, infrastructures, integrations, app security, and compliance needs before making the migration decision.



Don’t underestimate cloud migration costs. The key factors affecting the cost of migration include data storage, processing capabilities, security, testing, and monitoring tools.



How to test a legacy codebase without breaking anything? Learn here. Testing Legacy Codebase: What is, Common Problems and Best Practices 



Do consider the cost for all ongoing activities associated with the cloud, including the cost of reallocating your technical teams towards the migration.



Don’t forget about the relevant training. Oftentimes, migrating to the cloud means creating a completely new working environment for your teams. This applies to both IT and non-IT employees (such as HR, Finance, or Marketing).



Do make sure to conduct proper onboarding for all business units to help them get their bearings in the new environment. 



Don’t just lift-and-shift without further optimization. The purpose of the cloud shouldn't be all about presumably cheap storage. The real value of migration lies in cloud-native features — in particular, automatic scaling, performance management, and resource optimization, to name a few.



Do remember is that your software should be able to grow and evolve as your business grows. You should be able to make the necessary improvements and upgrades to ensure that the system stays up-to-date. You may need to plan any potential modifications and re-architecting activities in advance to take full advantage of your new cloud environment.



By following these best practices for a successful cloud migration strategy, we managed to accomplish a complex transition of the Webforms system to Microsoft Azure. The project was challenging from the jumpstart as some of the system elements weren't compatible with the cloud environment. That's why after building the cloud architecture, we paid great attention to rewriting the legacy components. Read the fullest case study from our experts to see the big picture of our cloud migration services and solutions.







ModLogix’s Best Practices for Successful Cloud Migration Strategy



One of the biggest questions to ask yourself when building a migration strategy is whether you really need the cloud.



Our experience shows that on-premise solutions, despite their low scalability, tend to have higher speed and greater bandwidth capacity than virtual machines in the cloud. Moreover, many solutions require specific hardware, which calls for re-engineering work so that a solution can work in the cloud. This was the case with one of our clients, a platform that offers database and verification services for clinical trials. On premise to cloud migration took less than a month; however, improvements to the solution itself are still underway.





Second, take the time to find a reliable cloud migration service provider who can deliver reengineering services such as adapting the system, rewriting and expanding the code, and improving the architecture. Cloud migration still offers its share of speed bumps along the way. While each case is different, having a fair share of bumps in the past can help identify risks ahead of time and understand how to avoid them or solve problems that arise.





If your system uses third-party tools, see whether they're compatible with the cloud. For example, one of our clients found that their fingerprint scanning tool’s provider used a different version of the product for recording data than our client for storing it, which resulted in the loss of some data records. It’s better to spot such issues before moving to the cloud. While you're still working with test data, you can afford to lose it without negative consequences for your business.





The final point to remember is — never migrate everything at once. Companies often underestimate the project’s complexity and simply rehost the product to the cloud, only to see the entire solution fall apart. This can only be avoided with step-by-step cloud migration and integration processes.



At ModLogix, we start by creating a step-by-step plan for the project. We put the development environment in the cloud and use it to check the compatibility of products, upgrade them if needed, and add custom code. We populate the environment with test data and test the functionality and performance of all product components. During this time, the system is still running in the old environment, which allows us to avoid long downtime during rehosting. And it's only after everything has started to work perfectly and all the risks have been taken care of that we proceed to moving the solution to the cloud.







Final Thoughts



Cloud migration promises many advantages — scalability, stability, and ease of business innovation are among them. At ModLogix, we know that software must serve the business. All the solutions we offer to our clients are reasonable and appropriate for their organization.

### Guide for Upgrading AngularJS to Angular with an Example of Real Case

AngularJS to Angular migration has become a crucial concern as the support for AngularJS ended on December 31st, 2021. This lack of upgrades means that an increasing number of businesses are considering the shift to Angular. 



But before getting started with migration, it is important to answer some key questions.




Apart from Google’s decision to discontinue support of AngularJS, what are other compelling reasons to migrate?



Is your company ready to make the transition?



What benefits will the migration offer?




We will address these questions in this blog post.



But first things first, what are AngularJS and Angular? AngularJS is a JavaScript framework developed by Google in 2009 and released in 2010. It streamlines development processes and simplifies testing. Thanks to the newly developed framework, a long, complex code of 17,000 lines can be rewritten into 1,500 lines in only three weeks.

However, as demands grew and developers encountered limitations, a new framework was needed to meet evolving application development requirements. This is what Angular was designed to fix, and migrating in the fastest and most efficient way is something every business leader should know how to do.







Why Your Business Should Consider AngularJS to Angular Migration



What are the main differences between AngularJS and Angular? Why is the migration relevant, and how will it affect your team and the application itself?



Ease of use 



AngularJS is far less reusable than its new version. Angular provides reusability of the elements due to its component-based architecture while facilitating high testability and easy maintenance. Although AngularJS is flexible, Angular is better structured, which goes back to its component-based architecture. It makes it more manageable and allows you to create large-scale applications.



Technology updates



As mentioned before, by the year 2021, Google will have stopped technical support and upgrades for AngularJS, which raises a huge concern for the businesses. This means that AngularJS migration to Angular is inevitable; however, the sooner your business makes this shift, the easier and more cost-efficient it is going to be. 



Technological updates are vital for your application as they ensure maximum stability for project progress. Angular team has decided to launch upgrades every six months, which guarantees the latest versions and the ultimate support. 



Speed



Firstly, Angular solves the problem of developing larger apps, including ERP system upgrade. It provides faster compilation, improves debugging, and facilitates flexibility. Secondly, Angular uses a more consistent language — TypeScript, that reduces runtime errors and provides code optimization, altogether leading to higher development velocity. Finally, while AngularJS relies on third-party tools, Angular uses Command Line Interface (CLI) that decreases application development duration.







Business Benefits of Migration from AngularJS to Angular



Let’s dig deeper into the main advantages of switching from AngularJS to Angular for business functionalities.



Mobile-oriented approach



Developed back in 2009, AngularJS does not support mobile devices. On the other hand, Angular delivers new techniques that allow you to create lightweight apps for mobile devices and browsers. Due to its component-based structure, Angular allows the so-called lazy scripting that uses particular modules only when needed as well as a better organization that provides faster page loading and higher performance.



Easy to maintain



Angular has an architecture that is based on components or services, in other words — modules. These modules enable an organization of application functionalities by separating them into reusable pieces of data. Each piece is responsible for one feature and stays independent of its system and APIs. All of the above ensures easier maintenance where developers can swap one component with another without rewriting the entire code.



Migration from AngularJS leaves more questions than answers. We interviewed top AngularJS experts to help you with migration. Experts Answer 10 Common Questions on How to Migrate from AngularJS 



Avoid code errors



Unlike AngularJS, which is based on JavaScript, Angular uses TypeScript which has a type-checking feature. This means that developers can avoid compile-time errors since the mistakes become easily detectable. Moreover, TypeScript code can be edited directly in the browser, making debugging easier and detecting errors at an early stage of development. 



Reduced costs



We have mentioned above that Angular reduces the overall development cycle as well as simplifies maintenance and debugging. Overall, it leads to cost savings along with smaller paychecks for developers since they will spend less time working on coding, testing legacy codebases, and so on. 



In addition to this, your business will cut bills on third-party tools like WebStorm or Brackets since Angular comes with an official Command Line Interface (CLI). Angular offers CLI that is optimized for its purpose; however, external tools like IDEs and UI kits are also available.



High performance



High performance derives from the module-based architecture of the Angular framework as opposed to AngularJS performance issues. By compartmentalizing chunks of data, developers can work on different pieces of code independently without facing the risk of creating unsustainable code. Due to the organization that Angular brings, labor within the teams can be divided, thus accelerating the process of development.  



On top of that, Angular offers best practices for fast performance, both network and runtime. For example, you can remove comments and whitespace as well as get rid of dead code with Uglify, provide bundling together with tree-shaking with Rollup, and use ngx-quicklink as a preloading strategy to download lazy-loaded modules. 



For more tips, see the Angular performance checklist on the GitHub page.



Setting Up an AngularJS to Angular Migration Plan



Converting from AngularJS to Angular is not a small task. It can impact your service delivery, especially if the software is key to your operations. You need a sound migration plan to make it a success. A typical AngularJS to Angular migration plan will include the following steps.



Set up TypeScript



To experience a seamless migration, you need to set up TypeScript. Use the @types/angular package to enable TypeScript interoperability with your existing JavaScript code. Also, by using the TypeScript Compiler and integrating TypeScript modules, you can achieve seamless integration between AngularJS and TypeScript.



Create a new build



In the migration process, it is vital that you create a new build of your legacy application using Angular CLI (Some people prefer webpack). By copying your AngularJS files to a new folder in the Angular structure, you establish a connection that automatically retains the features of your application.



Use the ngUpgrade toolkit



To facilitate easy migration, you can make use of the ngUpgrade toolkit. This toolkit enables the coexistence of both frameworks, allowing you to gradually update components and operate with AngularJS and Angular simultaneously.



Transfer services and components



During the migration, you will need the downgrade components feature to make Angular components available within the AngularJS part of your project. Additionally, it is important to carefully rewrite specific sections of your code to ensure compatibility and a seamless migration to the latest version of Angular.



Utilize UI-router



Routing plays a crucial role in the migration process. With ngUpgrade, the routing process is seamlessly supported by default, resulting in a trouble-free transition. You can also utilize the UI-Router to ensure efficient navigation and migration of your application's routes.



Determine the best approach for migration



There are three paths that you can take when thinking of moving from AngularJS to Angular.




Rewrite




This approach is self-explanatory — your team rewrites the entire code. Especially for outdated applications, also known as legacy apps, rewriting might be an adequate solution. Starting from scratch, you can re-design and rethink your application and implement new features on the go. 



Want to know more about legacy software rewriting process? Find your answers here: Should You Rehost, Rebuild, or Rewrite a Legacy Application With Latest Software? 



The downside is obvious — rewriting the entire application doesn’t happen overnight, which means that your team will have to work on both applications simultaneously. Your developers will recreate the application using Angular and simultaneously support and upgrade the existing one for current users.  




Hybrid with ngUpgrade




ngUpgrade — a library offered by Angular — allows you to keep running both frameworks simultaneously. This technology facilitates a slow and smooth transition that can last years or be relatively quick, depending on your goals and priorities. Your development team chooses one route at a time and starts upgrading from the bottom up. ngUpgrade allows Angular and AngularJS to coexist and work together without disrupting the application. 




Angular Elements




Angular Elements is a new package in Angular that allows you to transform Angular components into custom elements natively understood by browsers. Angular Elements eliminate the necessity of ngUpgrade; however, they are useful only for very big and complex applications. 







Сhoose a development team





You should integrate several factors into the decision-making process: the size of your development team, its capacity, and experience, as well as your current version of AngularJS. A small team with no resources for consultants should not consider Angular Elements as an option. If you have one of the latest AngularJS versions, ngUpgrade might be a good choice for your software; otherwise, go for the rewriting approach.





A big company with a lot of time and resources and a massively complex application should consider implementing Angular Elements; however, ngUpgrade might also be a choice for you.

The tools that were once ideal for most businesses have now become stale and obsolete. Legacy code is a major roadblock to your business's digital transformation – a hindrance to the maintainability and scalability of your software products.





To keep up with demands, there is a need to move your systems to modern infrastructure. What's the gain? Reduce lumps of technical debt, fix inefficiencies, create better experiences for customers, and, more importantly, increase revenue generation for your business.





While all this is well and good, application modernization can be challenging to say the least. How do you go about it? What’s the ideal roadmap for application modernization?



It took you years to build your legacy codebase; you won't modernize in a single day! In this article, you'll discover working strategies to develop an effective modernization roadmap for your applications. Learn from our step-by-step guide on how to create a strategic app modernization roadmap for your legacy system.



Understanding an App Modernization Roadmap



Legacy application modernization is a compound process that essentially involves moving a legacy codebase to a newer and better infrastructure which can also be seen as legacy software re-architecting or refactoring.



Consequently, an app modernization roadmap is a well-structured project plan for transitioning an existing application to modern infrastructure. It is a document that describes the path for the modernization of your existing applications. Depending on your organization’s size and goals, it can be a single page or more than 100 pages long, but it always includes steps for upgrading legacy applications or migrating data to new systems.



Your application modernization roadmap should be developed by your project team in conjunction with business stakeholders. The goal of this document is to provide a valid framework for transforming legacy applications into modern systems that are scalable, secure, and easier to maintain. 



It is important to create your roadmap at the beginning of an enterprise transformation project so that all stakeholders have a clear understanding of what they can expect from the process and when you show up the results.

Why You Need An Application Modernization Roadmap For Your Project



Before you begin any modernization project, it’s important to lay out a plan. A well-written application modernization roadmap will help you set realistic expectations, manage timelines and budgets, and identify potential roadblocks along the way.



Without a roadmap, you will get off track or confuse priorities as you move forward. A well-written roadmap document provides clear direction on where your project is headed and what needs to be done along the way.



A good application modernization roadmap will reveal:




The business goals of the project – the reasons why you’re modernizing, What problems you're trying to solve;









An overview of the project's scope and objectives;









A list of risks that may affect your project;









A list of human and technical resources that will be required for your project (e.g., people, time, money);

4 Strategies for Creating a Modernization Roadmap Document



We’ve distilled expert strategies for creating an application modernization roadmap that you can apply immediately to your legacy application modernization project.















Strategy #1: Learn from others



Just gather information. You don’t need to do much more than read up on what other businesses within your industry have said or are doing about modernizing their applications. Find out how these other businesses create roadmaps for specific purposes and then customize their steps to fit your business and needs. You can also talk with people who have already modernized their organizations’ software and are leveraging cloud computing or go to a conference or event where others talk about it and adopt the best practices.



Learn from others, then implement best practices on your projects. 3 Legacy Software Modernization Case Studies and 12 Lessons We’ve Learned 



This approach is useful when you don’t have the resources to hire a professional to produce such a document, nor the time and expertise to build an application modernization roadmap yourself.



Strategy #2. Start from the ground up 



You may choose to start your roadmap document from nothing. Use the guide described later in this article to create your roadmap document, one step at a time. 



If you have the resources, and necessary expertise to create your roadmap from scratch, then this is probably the best option for you. 



Here’s an important question to ask: How to speed up modernization delivery in legacy transformation? ModOps (DevOps principles for software modernization) is the best technique for modernizing legacy code because it works on DevOps principles such as agility – which are essential for keeping up with the fast-paced advancements in technology. In addition, it also encourages continuous and faster changes and more frequent deployments.  





To help modernize your legacy applications, your IT Ops team can use ModOps techniques. ModOps applies the best of DevOps practices to the legacy code modernization process so you can modernize effectively and fast. 





IT ModOps provides access to new tools and processes, such as continuous integration (CI) and continuous delivery (CD) that help teams work better together on projects. Get more done faster with fewer errors, so you can transform your businesses with less risk of failure or disruption to existing systems while also improving customer experience.





Strategy #3. Use pre-built templates



When you do not have time or resources to get into the nitty-gritty, this is another approach to developing a good roadmap document. You may use online templates to kick off your roadmap document according to application modernization trends. Templates split the roadmap document into major sections for you to fill up your project information. In a later section, we discuss a step-by-step guide that you can apply to fill up a pre-built template.



The problem with this approach is that it's not so reliable, since companies can't fully adjust pre-built templates for their needs. Plus It's suitable only for small companies with well-organized processes and documentation. And the outcomes aren't predictable.



Strategy #4: Get a professional service to modernize your applications



Instead of figuring out how to develop a roadmap and mounting despicable pressure on your team to implement your plan and deliver a modern product in no time, there’s a better option.



At Modlogix, we have just the right team and expertise to develop an actionable modernization roadmap for your business. And you can hire our dedicated legacy modernization company to bring this strategy to life, efficiently. It’s cost-effective and saves you and your team lots of trouble.



Technology moves so fast, so investing in a great service that will modernize your legacy systems quickly and effectively while your team focuses on new projects is the smartest thing to do.



Step-by-Step Guide Development of Modernization Roadmap for Legacy Applications



Developing an actionable app modernization roadmap for legacy systems is no easy feat. Because the roadmap dictates in practical terms all that needs to be done to move a legacy codebase to modern infrastructure, a modernization project cannot succeed without one. Here’s our comprehensive guide on how to plan a roadmap for application modernization:



Step 1. Audit and Assessment



Modernization starts with a thorough assessment of your current infrastructure. What do we mean by assessment? Here’s what you should look into:




inventory of all the hardware, software, and infrastructure,



integration issues,



compatibility issues,



outdated features (what isn't working).




Ask questions like why do I need to modernize my systems now? What issues do I have with my current software? What kind of problem is the new application supposed to solve?



Perform an in-depth analysis of your current system architecture and its main components. You may use your software architectural diagrams, a visual representation of the general structure of the software system, and the associations, limitations, and boundaries between each element, for a better analysis.



Do the analysis yourself, or invest in a dedicated software modernization service for a thorough analysis of your current architecture. 



The goal is to help you see what’s working, and what’s faulty. In your roadmap document, describe what needs to be modernized, and what the result of modernization will look like for your legacy applications.















Now that you know what modernization should look like, take the time to set SMART goals that your developer team will work towards achieving. SMART goals are Specific, Measurable, Achievable, Relevant, and Time-bound. Your goals may be expanded versions of the following:




improve end-user experience & security,



enhance business continuity.



improve the agility of your system.



reduce the total cost of owning and managing a legacy system.




Step 2. Business and Technical Understanding



Assess and outline your business and technical needs. Every change starts with the business objectives, that’s why you must outline every detail of your business needs in the early sections of your document. 



Answer questions such as: Why do you need to modernize your systems now? What issues do you have with your current software? What kind of problem is the new infrastructure supposed to solve?



To answer these questions, you should take the following actions:




Check on business documentation and business processes;









Conduct SWOT analysis to assess internal and external factors, as well as current and future potential. By analyzing the Strengths, Weaknesses, Opportunities, and Threats of your modernization project, you’ll get clear directives on how to proceed with modernization to assess internal and external factors, as well as current and future potential;









Perform user interviews to get feedback from your customers.




Next, study and outline your technical needs. In this section of your roadmap, you’ll answer technical questions such as: What kind of software are you looking for? Do you have any security requirements? What types of licenses will be necessary? 



Actions you can take to find answers to these questions:




Review the legacy codebase;









Conduct functional testing;









Check the security state.




How to safely test your legacy codebase? Learn here. Testing Legacy Codebase: What is, Common Problems and Best Practices 



Here you can calculate how much the maintenance of your system cost, TCO, and determine what exactly needs to be modernized (the whole system, its part, or you shouldn't do anything).



Step 3. Create a Modernization Plan - Choose the Right Approach



This stage is all about making the right choice regarding your legacy system before engaging in application modernization services. Put your requirements forward, look at your analysis outcomes, and the resources available to choose the best modernization approach.



You can either decommission your software and build a brand-new one, plugin API to expand functionality, buy an off-the-shelf solution if it corresponds to your needs or choose one of the popular modernization approaches (sometimes it can be a mix of approaches), and suitable technology. 



Here are the most common modernization approaches to choose from:




Refactoring




Refactoring is a great approach for businesses that want to move from containers to microservices to avoid software failures. You can use refactoring to improve the state of your software system – Make modifications in the configuration, solve tech issues, and make the code clear and maintainable. 




Rebuild




Instead of patching stuff here and there, why not just rebuild? It’s arguably the best approach. All components of your legacy system will be rebuilt, and new features are rewritten. In your roadmap document, describe exactly how every component of your legacy system will be rebuilt.




Replatforming




Replatforming allows you to migrate components of an application to a new platform with minimal changes in the code. You do not have to change core code or features, which is attractive for you who are not set on modifying "too much" of the new system.




Encapsulation




If all you want to achieve is to change the interface of your legacy system, then encapsulation is the approach you should use. Encapsulation is the process where you’ll reuse the main components of your system by building new access layers while omitting the legacy code sections. You’ll use APIs to connect the old (legacy code) components to the new access layers, thus providing new interfaces for old components.







 VIEW CASE STUDY  







Step 4. Define the Development Methodology and Set Timelines



The development workflow is a choice you should make. You can use the Agile methodology, which means that your stakeholders will see an early version of the final, modernized system soon after the project starts. 



You can use Jira (a standard-issue tracker) to manage tasks and communicate with stakeholders. Slack is a good option for internal communication and Google Docs or Microsoft products for documentation.



Break down the entire modernization process into smaller projects/phases that can be achieved within fixed time frames.



Software modernization projects don’t succeed without timelines. In this section of your roadmap document, create a high-level and detailed timeline for each phase. Then add some buffer time because things always take longer than expected! In your roadmap, assign people who have expertise in each area of development.



Prioritization: 



Certain sub-projects or phases will have higher priorities over others, and prioritization is often a major conflict amongst stakeholders.



Prioritizing modernization efforts is a key step in achieving an enterprise-wide modernization roadmap. The following steps will help you prioritize your efforts, using the Eisenhower matrix :




Identify the most strategic/urgent business processes.



Identify the most critical processes: If it’s a critical issue costing you money and customers, handle it first.



Automation may be a viable solution if the situation is urgent but not critical. And if it's neither urgent nor important, then it doesn’t bring any value! 








Step 5. Create a Risk Management Plan



Application modernization is an essential part of the digital transformation journey, and it can help you be more agile and efficient. But it's also a big undertaking that can introduce new risks to your organization.



Here are some tips for creating a risk management plan for application modernization:





Identify your risks. Before you can mitigate them, you have to know what they are. Work with your IT team to identify all of the possible threats that could happen during the application modernization process. Include both technical issues (such as data loss or system downtime) and business concerns (such as damage to company reputation).





Define how each risk will be mitigated. Once you’ve identified all of your risks, it’s time to figure out how each one will be addressed if it happens during the process of modernizing applications. For example, if there’s an increased chance of downtime during the cloud migration process, create a contingency plan that outlines how employees can still access their systems while they’re down (such as using mobile apps or email).









Step 6. List KPIs and other vital Metrics for Your System



In your roadmap document, also set key assessment and success metrics to assess the progress of your modernization project. 



Here is a few important modernization KPIs to look into:



Performance metrics: How fast does the system under modernization perform and how quickly can it process requests? This can include response time, throughput, and other similar measurements.



Availability metrics: How often is your modernized system available? This can include uptime or downtime measurements.



Security metrics: How secure is the new system? This could include security vulnerabilities, security breaches, and other similar measurements.



Cost efficiency metrics: How much money do you anticipate spending to maintain your modernized system? This could include hardware costs, software costs, and other similar expenses.



Step 7. Plan for Cutover 



The cutover is the period during which the new system is being introduced and made available to customers. Cutover plans will vary depending on the project, but some common activities need to be addressed:




Plan for a complete system cutover before your system goes live.









Create a checklist of tasks that need to be completed before you switch over. Put this list in an email and send it to all stakeholders. Include a callout explaining why each item is important so that if someone finds something missing they can easily add it to their schedule.









Make sure no one touches anything on your production environment except those who have been permitted by the project manager or lead developer.




And you are ready to modernize!

4 Pitfalls to Keep in Mind During Creation of App Modernization Roadmap



There are various challenges that you might encounter when creating an application modernization roadmap. These bottlenecks can result in various consequences, including budget overrun, increased technical debt, compromised application quality, or even missed opportunities for change and innovation. With that in mind, here are the pitfalls to have in mind:



Inadequately defined business needs 



One of the most overlooked pitfalls when defining the roadmap for application code modernization is not fully comprehending the business objectives and requirements. And on top of that, convincing non-IT business executives to completely overhaul what’s already working for them can also be an uphill task. If the modernization plan doesn’t align with business goals and key stakeholders are not on board, the efforts will be fruitless since the solution will unlike drive desired benefits. 



It's imperative to conduct an in-depth analysis of the current application before pitching the idea to key stakeholders in a bid to understand their expectations and get budget approval. Create a clear list of resources that the project needs and present it in familiar terms so that everyone can buy in. Involving everyone to garner feedback and expectations will help you understand and define the underlying business needs better. 



Old and outdated application dependencies 



Nearly all software applications are bound to encounter the challenge of technical debt sometime in their lifetime. In other words, the modules powering the application might become outdated over time and negatively impact your organization’s business agility. This is also true for the underlying dependencies, such as frameworks, libraries, and platforms. Unless these dependencies are updated, the app modernization process might delay or fail due to incompatibility or security vulnerability issues. 



While creating the roadmap, it will help if you thoroughly evaluate the current dependencies and isolate any obsolete component that might require an upgrade or replacement. This will help you create a solid app modernization roadmap that will form a foundation for integrating new technologies and implementing security enhancements. And when the time to replace a module comes, deconstructing the source code to its base fundamentals to make functional updates iteratively will give your team an easier time than rewriting it from scratch. 



Timeline-based roadmaps



Another big pitfall that many CTOs get themselves into when preparing for app modernization is adopting a timeline-based roadmap. While it’s well and good to have deadlines and run the project on a schedule, successfully executing app modernization strategies on arbitrary timelines is nigh impossible. In other words, you can’t rush the process without factoring in the complexity involved or availability of additional resources when needed.



It’s important to build a roadmap for app modernization with a realistic approach, especially if you’re going to achieve complete functionality, reduce technical debt, and improve quality. With a roadmap that thinks into the future, you’ll implement an effective modernization process that fulfills the testing and quality assurance standards to drive desired business outcomes.



Revisioning the governance process 



Modernizing legacy apps is more than just making technological improvements. While creating the roadmap, it’s important to factor in how different organizational processes, structures, and skills are going to evolve as well and communicate the same to key stakeholders. Failing to revise the governance process with everyone on board might result in resistance to change, slowed down decision-making, or even general confusion. 



However, not everything requires reorganization. It will help if you spare ample time to think it over and define the feasibility of change before inclusion in the roadmap. For instance, if you intend to achieve efficient automation, revising the whole governance process might not be necessary. Instead, you can plan and implement individual changes in the governance process or frameworks during CI/CD. 



After Your Modernization Roadmap, What Next?



The next big step is to get your roadmap approved by your team and stakeholders.



The devil is in the details! This statement can't be more true when it comes to creating a great roadmap. To make sure that your roadmap is truly helpful and functional, here’s what to do:



Share it with your team members and stakeholders so that everyone can see what's coming up and how they fit into these plans for the future. Get feedback on how well the individual stakeholders’ needs were addressed by this particular roadmap.



It's true: your roadmap shouldn't be a static document. You do need to keep it up-to-date as you go, but it shouldn't be a rigid process. If you have a major change in your company's direction or if you have new business goals, then yes — you should update your roadmap.

8. Implement training for user adoption



Provide users with resources and training courses to lower the learning curve and increase adoption rates.



9. Migrate users



Onboard users and move the Access database to Power Apps after setting necessary rights and permissions for individual access. You can use the active directory to manage user authentication.



10. Implement ongoing monitoring and support



Monitor usage and performance on an ongoing basis to provide necessary support and maintenance whenever issues arise.



Prevalent Challenges in Migrating from MS Access to Power Apps



While Power Apps offer a range of business benefits to take your organization to new heights, the migration process is not that easy. Expect to experience various challenges in migrating from MS Access to Power Apps, including: 



Data migration and integration 



Businesses usually integrate their access databases with external systems or data sources, which must be replicated in Power Apps. However, migrating and integrating data from these sources can be an uphill task, given that they all have unique architectures. This requires you to develop an encompassing data migration strategy that extends to extraction, transformation, and loading processes for a seamless transition. Moreover, you can also leverage native Power Apps connectors like Dynamics 365 or SharePoint to integrate the data. 



Legacy system integration 



The migration process can be more complicated if your existing Access database is integrated with legacy software or technologies, limiting its compatibility with Power Apps. To solve this, you can leverage alternative integration methods, such as custom API and connectors as data gateways for on-premise connections. 



Cost considerations 



There are various additional costs involved with the migration other than the project’s expense, including licensing fees and infrastructure requirements. Assess the available Power Apps licensing options to determine the best pricing model that offers swift scalability and long-term business benefits.

### Top 10 Reasons to Convert MS Access Database to Power Platform

While Microsoft Access has long been a reliable database management solution, many businesses are now finding it outdated and limiting. Luckily, Power Platform — a better alternative to Microsoft Access has emerged to save the day. The power platform, a low-code tool, modernizes database management systems and access through its advanced features and user-friendly interface. Simply put, it is the future of business intelligence and app development!



If you would like to learn valid reasons for migrating from MS Access to Power Apps, you came to the right place. In this article, we explore 10 of the most crucial reasons why migration is necessary. Without doubt, the advantages for converting MS Access database to Power Platform are well pronounced. Let’s begin.



What is Microsoft Access?



Microsoft Access is a relational database management system (RDBMS) that helps businesses and individuals to organize, store, and manage their data - whether for a simple contact list or a complex inventory system.



Access was developed by Microsoft in 1992, and it has been a part of the Microsoft Office suite of applications ever since. Its friendly user interface and low-code development capabilities are two of its most significant advantages. This makes it a convenient option for users with no extensive programming knowledge to develop databases and applications.



However, as technology advances, it becomes increasingly necessary for businesses to migrate their Microsoft Access databases to more modern and secure databases, such as Power Platform.



Reasons You Should Stop Using Microsoft Access 



Access may have been popular in the past, but it is no longer a viable option.Let’s explore the reasons to migrate your Microsoft Access database to Power Platform.



Low capacity



A database that contains large files or images could quickly reach the 2 GB limit for Microsoft Access. The result will be a slow and unstable database, which may lead to data loss.



Performance issues



Microsoft Access has difficulty handling large databases and complex applications, which leads to poor performance when dealing with queries of big size. Consequently, as your organization's databases grow in size and complexity, they become increasingly difficult to maintain and update with the program.



Prone to corruption



Microsoft Access databases are prone to corruption. The program can become unstable or crash, leading to lost or damaged data. Furthermore, Access databases can be more vulnerable to data corruption when multiple users are accessing the same database simultaneously.



Security vulnerabilities



Although Microsoft Access provides security features, the security of its databases may not be suitable for critical applications. Users who are unfamiliar with security principles and settings may unintentionally open, delete, or modify a database.



Incapacity to scale



One of the biggest differences when it comes to Microsoft Access vs Power Apps is that the former may not be able to keep up as your business grows. You may thus find it increasingly difficult to manage and maintain your database. 



This is particularly a major area of concern for most businesses, as almost 90% of organizations believe that if they fail to scale and complete digital transformation initiatives within 12 months, their revenue will suffer.



Multiple versions of truth



It can be difficult to ensure everyone in your organization has the latest data when using Microsoft Access. When multiple versions of the truth exist, there is a risk of confusion and errors in decision-making.



Limited scripting ability



Microsoft Access' limited scripting capabilities and difficulty executing advanced queries provide further cases to convert your MS Access database to Power Platform. Users may find it difficult to execute complex process control logic and automation as a result.



Desktop limitations



Microsoft Access is a desktop-based application, which limits its accessibility and collaboration capabilities. With more businesses moving to cloud-based solutions, Access's desktop limitations make it less than ideal for modern business needs.



Reasons to Migrate from MS Access to Power Platform



Power Platform is a low-code development platform that allows users to build custom business solutions, including mobile apps, workflows, and chatbots, without the need for extensive coding knowledge or IT support. 



So why convert Access databases to Power Apps? Here are the benefits of migrating from MS Access to Power Apps and reasons why you should also make the upgrade.



All-cloud architecture



Due to the fact Power Platform is entirely cloud-based, businesses can access their applications and data instantly, from anywhere, anytime, and on any device as long as they have internet access.

### Challenges with Legacy System Modernization and How to Overcome Them

No matter how much businesses want to get rid of legacy tech, more than 66% still use them for everyday operations. True, legacy systems are essential to these businesses, but they’re also old and expensive to maintain. According to Information Week, IT departments in the US spend $85 billion annually fixing and maintaining outdated tech.



So, why not replace these systems? The benefits of doing so are significant, including improved scalability, better user experience, flexibility, efficiency, and competitive advantage. The problem is how to modernize without disrupting the business.



There are a number of legacy modernization approaches, but each has its own challenges. For example, re-platforming can be expensive and time-consuming. However, by taking a phased modernization strategy and working with a reliable partner, organizations can modernize their legacy systems without affecting business operations. 



In this article, we will cover some of the challenges of legacy system upgrading and some tips on how to overcome them.



Read on…



What are the Risks and Issues of Legacy Software



Legacy software is any kind of system, software, or application that is outdated and no longer supported but still in use by an organization despite its outdated technology.



Some of the signs that you have a legacy system are:




Lack of or limited support. Discontinued support for legacy systems is the first sign that you have a dinosaur on your hands. Unfortunately, you’ll have an uphill battle updating and maintaining the system.



Outdated user interface. A legacy system will have a user interface and navigation that are noticeably outdated and clumsy. 



Reliance on outdated tech stack. If the system is reliant on outdated programming languages or databases, then it’s probably time to look for a replacement. 



Incompatibility with newer systems. If you're experiencing compatibility issues with modern software, making it hard to integrate with newer systems, then that is a sure sign that your system is old.



Slow and cumbersome. Legacy systems can be slow and clunky in comparison to modern systems. This can create long load times, long waiting periods for data to update, or even cause programs to crash.




While legacy systems may be the mainstay of your business, their maintenance and usage carry certain risks. Apart from the cost of maintaining legacy systems, some other downsides of using old technology include.




Limited functionality. Limited functionality is one of the biggest legacy issues for businesses. Old systems often lack the capabilities to efficiently handle modern data and applications, leading to a decrease in productivity.



Increased vulnerability to security issues. Outdated systems lack modern security protocols and the ability to automatically patch security flaws, so they are much more exposed to cyberattacks.



Data silos. Legacy systems are typically not designed to be merged with modern systems. This can cause isolation from other systems, leading to data silos.



Difficulty finding skilled personnel to maintain the system. Legacy systems often require specialist skills to maintain them. As such, it can be hard to find qualified personnel to work on the system, significantly increasing operational costs and time.



Loss of competitive advantage. Companies that use outdated systems will have difficulty adapting quickly to changing customer demands, market trends, and other competitive pressures. This can cause them to lose their competitive advantage. 



Potential legal and financial risks. Many companies are required to comply with certain standards or regulations. Legacy IT systems may not be able to meet those standards or adhere to regulations, and this could lead to hefty fines or other penalties. 




Because of these downsides, companies should consider transitioning to more modern systems or legacy system integration in order to keep up with the times and avoid potential risks. 



5 Legacy System Modernization Challenges



While modernizing your existing system can bring countless advantages and improve user experience, there are also a few difficulties of legacy system upgrading. Some of the challenges to think about when upgrading from a legacy application are.



User acceptance



Transition to a new system is often met with resistance. It can be hard to get workers to accept and integrate the new system into their everyday routines. This means that whenever a modernization effort is undertaken, significant effort must go toward getting user acceptance.



Seamless integration of new applications and technologies



The seamless integration of new applications and technologies with the elements of your existing legacy infrastructure is another legacy system modernization challenge to think about. It requires a lot of forethought and planning to ensure the newer applications are compatible with the code of the legacy system.



Data loss



Legacy systems often contain a vast amount of vital data which needs to be converted to the new system. Unfortunately, it is not always possible to convert all data from the old to the new. This can lead to significant data loss and is one of the major challenges while modernizing an outdated software.



Workflow issues 



Redesigning and re-engineering a legacy system can often result in a mismatch between the end user and the workflow. This is one of the biggest issues while migrating legacy applications and users will find it difficult to understand and use the system. If this is not addressed preferably via training, it can lead to poor employee engagement.



The cost



Replacing an entire system is never cheap and can be a huge financial burden on any organization. In fact, according to Workday, cost is one of the top challenges with upgrading from legacy software. All costs associated with the modernization effort need to be carefully considered before any decisions are taken.



Difficulties with choosing the right strategy



One of the challenges in migrating a legacy system is the difficulty in choosing a strategy. There is no single ‘right’ way to do it. Difficulty in choosing the right replacement strategy or problems in identifying a reliable cloud provider can delay or even deter IT decision-makers from their modernization plans.2



How to Overcome Legacy Systems Challenges: Strategies and Best Practice



Modernization of existing technology is key to remaining competitive and efficient in an ever-evolving technological landscape. But how can you go about it in an effective and efficient manner without compromising everyday operations? These strategies and best practices will help you resolve the difficulties in replacing apps legacy technology.



Assess your legacy system



The first step in updating any legacy system is to do an assessment. This starts with a total software review. Even if your software is cutting-edge, it may fall short of meeting your current company's needs. So, consider your business development objectives and which software can help you achieve them.



Explore the current solutions



Next, take a look at the current offerings/ solutions on the market. Chances are you will find a SaaS that will meet your business development needs. If there is no obvious fit, then you may want to consider custom software development.



Choose your legacy system modernization strategy



Now, it’s time to decide on a strategy for modernizing your legacy system. This can be done through a number of strategies, including re-platforming, code refactoring, enhancement and migration, and software rebuilding. Making the right decision requires careful consideration. The assistance of an IT professional may be of value here.

Select an optimal technology stack



This is where you’ll decide whether to go for complete cloud migration or choose the hybrid model. The size of your organization, your method of managing big data, as well as the stack speed system you want, will play a role in this decision.



Set up a legacy system retirement schedule



You will not suspend your legacy system all at once. Therefore, have a plan in place to roll out the new system over a period of time. This strategy can help reduce disruption. It will also provide a more cost-effective solution, and give you the time to plan and prepare for potential legacy application migration challenges that may arise.



Train your employees



Don't overlook the importance of training. When it comes to legacy system modernization, your employees may not be too enthusiastic about the changes. Training can alleviate potential apathy and help them get familiar with the new infrastructure faster.



Plan for future upgrades



Despite the best efforts, modernization could disrupt the everyday flow of the organization. It can be pricey too. Therefore, it is important to plan and allocate a budget for it ahead of time. This will help make the process as seamless as technically possible.

### Full Guide of Legacy Software Assessment

Outdated systems evoke intriguing conversations among tech geeks because there is no one standard way of testing a legacy system to assess its functionality. While these systems can work effectively for years, it reaches a point where the costs of maintaining and optimizing legacy software become unreasonably high. This is not to mention the low-performance issues due to incompatibility with new technology. 



But why should you test legacy software, and how are legacy systems assessed in the first place? This article highlights the reasons for assessing a legacy system, the steps to follow, and the challenges you'll likely experience. Read through to stay updated. 



Assessment of Legacy Software: What Is It?



The assessment of legacy software is a high-level process that involves examining and evaluating the components of an old system. Old software, in this case, is a system architecture that has served your business for five years or more without servicing. 



Typically, this assessment helps you point out the system's strengths and weaknesses to determine whether it can meet the prevailing needs. If not, exploring legacy modernization solutions should be the next step. 



Legacy system assessment is a critical step for any IT-driven industry. However, the following sectors may benefit more and have a competitive edge after evaluating legacy software to modernize it: 




Healthcare: conducting a thorough evaluation of outdated systems can help healthcare organizations optimize their software for HIPAA regulatory compliance. 



Financial services: all financial institutions that leverage a legacy solution can assess it to identify and mitigate compliance or security loopholes. 



Manufacturing: manufacturers can evaluate their old software architectures to identify cost-saving opportunities and integrate new technologies, such as IoT. 



Government: governments can audit their old operating systems to implement digital transformation and improve service delivery in growing populations. 




Generally, organizations implement legacy software assessment when planning to upgrade the existing solution as part of a bigger digital transformation agenda or to meet current business needs. Also, evaluating older software can help identify integration challenges for proactive remediation before implementing an upgrade. 



Reasons Why You Need to Assess Legacy Software



Although legacy systems are technically out of date, some organizations still use them to complement various business functions. But even if your old operating system works, you might want to evaluate it due to the following reasons: 



Security risks 



Older tech solutions aren’t built to withstand advanced cybersecurity exploitations, which can jeopardize the security of your entire IT infrastructure. In this case, legacy software evaluation will help you identify security vulnerabilities and suggest remediation measures to seal the loopholes. 



Performance challenges 



You can assess legacy software to identify the performance challenges it might have developed over time, such as memory leaks, sudden outages, or slower responses. This helps you pinpoint the root cause of slowed performance and ways of solving the issue. 



Old technology limitations 



Conducting a thorough assessment of your system is the first step to overcoming the tech limitations of legacy software. These limitations include a limited integration functionality, which can hinder key modernization steps, such as data migration. 



Regulatory and compliance requirements 



Another reason to evaluate your old software is to find regulatory compliance gaps that may put your business at risk of huge losses in fines and a tainted reputation. Technically, assessing a legacy software helps you establish whether it meets the current regulatory standards. 



The cost reduction factor 



Testing a legacy system to assess its functionality can help you identify cost savings opportunities, such as moving to a cloud based platform. This is cost-effective in the long haul because you won't strain meeting expensive legacy system maintenance costs like acquiring specialized software.  



8 Steps to Assessing a Legacy Software



Knowing how to assess legacy software can be an uphill endeavor at first, thanks to the complex and challenging process. Follow these steps to get started: 



1) Define the goal and scope



This step entails understanding why your organization built the software in the first place and the primary function that it serves. Having these details will help you understand how to identify a legacy system component that’s critical in driving key business functions. 



2) Code quality evaluation 



Your legacy code was written in programming languages that don’t match current standards, making it imperative to evaluate its structure and complexity. Assessing the code helps you understand its maintenance needs and scalability or performance capabilities. 



3) Single out dependencies 



As an outdated system, legacy software often includes retired hardware or software components in its architecture. In this step, single out these components, or dependencies, to examine whether they are still functional. 



4) Establish security risks



The old technology platform might pose higher cybersecurity risks since it doesn’t feature an automatic update functionality to patch vulnerabilities. With that in mind, examine it carefully to identify security loopholes that are susceptible to easy exploitation. 



5) Examine documentation 



Typically, legacy software is associated with poor documentation, making it important to assess whether the existing documentation is adequate or requires an update.

6) User feedback analytics 



Conduct a poll or questionnaire survey to gather feedback on the system’s level of user experience. Doing this helps you to collect insightful feedback to help optimize the software's usability or functionality.  



7) Calculate the maintenance costs



Add the total budget for maintaining the old technology platform. While doing so, remember to factor in debugging expenses and the costs of upgrading dependencies. Also,  consider any other expenses that might be incurred to optimize it for compatibility with modern technology.

8) Strategize an action plan 



Lastly, develop a solid plan based on the findings of the legacy system assessment, and outline the next steps to follow to fix the identified issues. Again, it will help if you take a long-lasting approach that won't sink your organization into technical debt, even if it means re-platforming, migrating, or building a new platform from scratch. 



Challenges of the Legacy System Assessment



There are several common challenges that organizations face when testing legacy code, including:



Documentation can be scarce and/or outdated



One of the first challenges you'll face when assessing a legacy system is a lack of documentation. Over the years, documentation can simply disappear. Even when you find the documentation, it can be outdated and misleading, as it may not reflect the current state of the software.



Large monolithic applications are difficult to comprehend



Another challenge with legacy software is that it can be very difficult to understand. Large, monolithic applications can be complex and confusing. And when you can identify and isolate issues, it may be difficult to implement changes without introducing new problems.

Requires a lot of time and effort



Testing a legacy system can be a time-consuming and labor-intensive process. It can take weeks or even months to fully understand an application. And, once you have a clear understanding of the application, you still have to identify any issues and make recommendations.



Automated testing may not be possible



Automated testing is a vital part of the software development process. It helps identify errors and potential problems early in the development cycle. However, automated testing may not be possible when evaluating legacy software. This means it is difficult to perform regression testing and to ensure that changes do not introduce new issues.



Disruption to business-critical processes



When you test legacy software, changes may have to be made to the software or how it is used, which can disrupt business-critical processes. This can cause downtime or business disruptions.



To avoid this, a phased approach is best. Adopt agile methodology when doing your assessments and manage the process in small incremental phases or chunks.

### PHP 5 End of Life: Prepare for Upgrading to PHP 7 Using This Ultimate Guide 

PHP 5 has been a popular scripting language for web development for almost two decades. However, as of 2019, PHP 5 has reached its end of life and is no longer receiving security updates, leaving websites running on PHP 5 vulnerable to attacks.  



It's crucial for website owners and developers to upgrade to PHP 7 or 8 to ensure their websites remain secure and performant. In this article, we will discuss the implications of PHP 5 end of life and the benefits of upgrading to PHP 7 or 8. We will also provide a step-by-step guide on how to upgrade your website from PHP 5 to the latest version. 



Why Do Companies Use PHP to Build Websites?  



PHP is a programming language that has been around since 1994 and is widely used for web development. While it may not be as trendy as some of the newer languages, PHP remains a popular choice for companies and developers alike: MailChimp, Slack, Wikipedia, Facebook, and others. 



There is a vast amount of PHP legacy code out there, which means that many companies have already invested significant resources into developing applications and websites using PHP. It can be difficult and costly to migrate away from a technology that is deeply integrated in a company's infrastructure. 



Another reason for the continued use of PHP is its ease of use. PHP is a server-side language, which means that it can be used to create dynamic websites that can interact with databases and other backend systems.  



PHP is also an open-source language, which means that it is freely available and can be modified to suit a company's specific needs. 



PHP 5 End of Life Reveals Vulnerabilities 



However, as with all software, some PHP versions are in critical need of upgrade. In January 2019, PHP 5 reached its end of life (EOL), meaning that it will no longer receive official security updates or bug fixes. While PHP is used by 77.4% of all the websites, version 5 is used by 16.9% of all the websites [W3Techs.com]. What is hidden in legacy PHP 5? 



Security issues 



Without security updates, PHP 5 is already vulnerable to new threats, and any security flaws that are discovered will not be patched. This means that any applications running on PHP 5 could be at risk of cyberattacks, and the longer an application continues to run on an EOL version of PHP, the greater the risk becomes.  



Every month and year, the list of vulnerabilities and downtimes is growing. But are you ready to bear this risk? 



Compliance issues   



Companies that have applications running on PHP 5 may face compliance issues if they are operating in regulated industries like finance or healthcare. For example, PCI-DSS (Payment Card Industry Data Security Standard) compliance requires that all software used in payment processing systems is up-to-date and receives security updates. 



Legacy libraries 



Like PHP 5 itself, many of its third-party libraries are also outdated, and if these libraries also have vulnerabilities, they can pose a security risk. 



Why Upgrade PHP 5 to 7 or Higher? 



Is it worth to upgrade from PHP 5 to 7? PHP upgrade 5 to 7 or higher offers several benefits, including: 



Improved Performance 



PHP 7 is significantly faster than PHP 5, with up to 2-3 times faster execution speed. This is achieved through new features like Zend Engine 3.0 and other performance optimizations, resulting in better response times and faster page load speeds. 



Enhanced Security 



PHP 7 and higher versions come with improved security features, including better encryption, improved password hashing, and support for more secure cryptographic algorithms. These security enhancements help to reduce the risk of security breaches and data theft. 



Better Memory Management  



PHP 7 and higher versions introduce better memory management, which results in more efficient use of server resources. This translates to lower hosting costs and improved server performance. 



Compatibility with Latest Applications and Tools 



As more and more applications are built using PHP 7, developers who stick to PHP 5 will increasingly find that they cannot use the latest applications or frameworks. Upgrading to PHP 7 or higher ensures that developers can use the latest tools and applications like the latest releases of WordPress, Joomla, and Drupal. 



Long-term Support 



PHP 5 has already reached its EOL and is no longer receiving official support or security updates. Upgrading to PHP 7 or higher ensures that developers can take advantage of ongoing support and updates from the PHP community, reducing the risk of vulnerabilities. 



How to Upgrade from PHP 5 to PHP 7? 



Upgrading an existing PHP 5 codebase to PHP 7 or higher requires a few steps to ensure a smooth transition. Here is a general guide on how to upgrade from PHP 5 to PHP 7 or higher: 



1. Check Compatibility



Before upgrading, it is essential to verify that your existing codebase is compatible with PHP 7. The easiest way to do this is to use a PHP 7 compatibility checker tool that scans your codebase for any issues that may arise during the upgrade process.  



Alternatively, you may need a website audit and assessment to determine deprecated PHP 5 code or functionality.  



2. Prepare a Checklist for Backward Incompatible Items



Considering a list of backward incompatible changes between PHP 5.6 and PHP 7.0, the audit allows to set up the effective migration path and not miss anything. 



3. Update Dependencies 



Ensure that any third-party libraries or dependencies used in the codebase are compatible with PHP 7 or higher. Spoiler, there will be a lot that will be deprecated in newer PHP versions.  



If not, check for available updates and upgrade them before proceeding. 



4. Upgrade PHP 5 code PHP 7 



Depending on the hosting environment, upgrading PHP may require some steps to be followed. Typically, it is possible to upgrade PHP via the hosting control panel or by running an upgrade command on the server. But, it is recommended to consult with the hosting provider for specific instructions on upgrading PHP. 



Another approach is to re-do the website module by module which involves PHP refactoring legacy code process. This approach is useful if your software has a million lines of legacy PHP code and is unlikely to be upgraded without critical bugs or downtimes.   



5. Test and Debug 



Once the codebase is upgraded, it is essential to test and debug the application thoroughly. Some features or functions may no longer work as expected due to changes in the language's syntax or behavior, so it is essential to ensure that everything works as intended. 



6. Optimize for PHP 7 



Finally, after upgrading to PHP 7, it is recommended to take advantage of the new features and improvements to optimize the codebase further. This may involve revising or rewriting parts of the codebase to make use of PHP 7's performance improvements and features. 



Successful website upgrade from PHP 5 to PHP 7 or higher requires checking for compatibility, updating dependencies, upgrading PHP, testing and debugging, and optimizing the codebase further. Following these steps ensures a smooth transition and takes advantage of the performance and security benefits offered by PHP 7+.

### 10 Reasons to Convert a Desktop Application into a Web Application

Web enablement has become a must for businesses that want to expand their capabilities, get closer to the customers, and stay ahead of the competition. As of February 2023, the global mobile market penetration reached 59.42% while the desktop global share shrank to 38.53% from 43.15% in 2021.



While this data reveals the growing popularity of web apps, it also paints an unpleasant picture for companies and institutions still using legacy software. These older programs no longer have a place in today's digital world. They neither meet the needs of today's users nor offer the advantages of SaaS.



So, what is a web-based application, and how is it different from a desktop program? Why should you convert a Windows application to a web application? What factors should you consider when deciding whether to migrate?



This blog provides answers to all these questions. We'll also share some insights on how to ensure a smooth transition from a desktop to a cloud application without challenges.Ready to make the switch? Let’s get started!



Web App vs Desktop App: How Are They Different?



A web application is a program that can be accessed via a web browser. For the software to work properly, you need to have an Internet connection or other form of network connection. However, it doesn't require you to install it on your computer. 



Google Docs, Netflix, and Trello are common examples of web-based applications.



A desktop application, on the other hand, is software that runs locally on your laptop, desktop, or other computer devices. You must install it on your computer device for it to work, but it doesn’t require an Internet connection to work. 



Among the most popular desktop apps are MS Office programs, Adobe Photoshop, Adobe Illustrator, and media players.



10 Reasons Why Turn a Desktop Application into a Web-Based



With the differences between desktop and web-based software clarified, the next question now is: Why turn a desktop application into a web-based application? 



Here are the reasons for moving to a web application from a desktop framework:



1. Performance Issues of Legacy Desktop Apps



Desktop software often requires a larger amount of storage on the computer's hard drive for the deployment of its associated files. This ultimately slows down the user’s system, hampering performance and efficiency.But, unlike desktop programs, newer web apps don’t require large storage spaces.  Users only need an Internet connection to enjoy light and fast software performance.



2. Accessibility Everywhere, Anytime



The fact that desktop app users are unable to access their files when away from the computer device they are installed has always been a frustration. 



The good news is, with web apps, this problem is eliminated. With a web application, users can access their files from anywhere, and use any alternative device as long as they have an Internet connection and login details.



3. No Installation is Required





A major purpose of a conversion desktop application to a web application is to eliminate the overwhelming need for installation. Web apps do not require installation on every device you want to use them on. As long as the user has a web browser, they can access the application from anywhere without installing anything.





This means users can work on the go on any connected device and achieve the same productivity level as if they were seated at their desktop computer or laptop in the office.





4. Can Work across All Connected Devices



Web applications offer cross-platform compatibility as they don’t require standalone codes that are specific to a particular operating system or hardware.



Web-based programs, therefore, help you avoid many of the compatibility issues associated with desktop applications as well as increase the value of your existing hardware.



5. More intuitive interface





Most desktop applications were developed at a time when user interface expectations and design patterns were vastly different from what they are today.





Today, consumers are accustomed to web and cloud-based software that is not only fast and efficient but also has sleeker and more sophisticated interfaces. This streamlined improves work efficiency for teams, end users, stakeholders, and is a top reason why desktop apps turn into web apps. 





All in all, who wants to operate in an outdated and inconvenient Windows XP-like system when there’re Trello, Spotify, Facebook, Amazon, and others on the market?



6. Updates Automatically



Do you find it bothersome to have to update your desktop program regularly?



Thanks to automated updates, the frequency of on-premise app updates has reduced, However, some desktop software may still require a manual upgrade from time to time. A web app, on the other hand, lets the user concentrate on the task at hand and saves them time, since the software updates automatically.



7. Requires Little Processing Power





Unlike on-premise programs, web-based apps are typically resource-light. This is because most of the heavy processing takes place in the cloud, on the server, or in the developer's enterprise database system.





Therefore, customers don't need to “upgrade to the latest version” every year or two. This ensures that teams and organizations get a better return on their IT investments, and individual users are not limited in any way in their productivity.





8. Provide Better Cost-efficiency



Most on-premise apps are on-off purchases, in contrast to most online software that offers flexible payment options with short trial periods. For example, if you need the app for a single task or a short period, you can simply sign up for a week's worth of access.



A desktop app, on the other hand, typically offers yearly or monthly subscription plans. Consequently, users may end up wasting money on an offline app they require access to for just a week. This can lead to frustration over time. In other words, web-based applications are actually cheaper.



9. Easy Integration with Third-party Software



One of the major advantages of migrating desktop applications to web applications is the fast and easy integration with third-party programs.



A team could integrate Zoom or Google Meet to hold a virtual video conference when collaborating on a Google Doc or an online PDF editor, for example. However, using a desktop PowerPoint or Excel Sheet program would not provide them with this same convenience and flexibility.



10. Easy Scalability



As a final point, web apps are designed to scale and evolve with the needs of individual users, teams, and organizations. Additionally, multiple users can access and use the application simultaneously without experiencing any issues. The ability of online software to support collaborative work by project teams is one of the most compelling reasons for converting desktop to a web application.



When authorized users can access and review information and resources consistently and equally, they gain a better understanding of the project. They are also able to make better and more productive inputs.



How to Determine if You Really Need a Migration to the Web Application



Making the move from an offline to a web application is a major business decision. It requires careful planning, reviews, retooling, and possibly upskilling your staff. But how do you determine the web is the right home for your app? 



Here are some questions to ask yourself when preparing to migrate:




What is the purpose of migrating desktop applications to a web-based program?



How will the transition benefit my business and the app in general?



Does this align with my project goals and plans? Do I want to grow the project?



How will my business reap the benefits of converting a desktop application to a web application?



How will the transition affect primary users who interact with the app?



Do customers need the app on smartphones or multiple devices?



In the event that an Internet connection fails, what happens? Is it harming productivity?



How can I prevent risks of porting to the web? 



How will it affect data security?



Is the competition using a more modern, accessible, and user-friendly app?



What is the cost of migration? What are the maintenance costs of my existing app? Try to compare these numbers. 



How long will the migration approximately take?



What's the next steps after the app has been converted to the web?



What’s the projection for the next 5 years? How will I picture my app?



What steps do me and my team need to take to prepare for pre-migration, during the desktop to web development, and the launch?




Answering these questions clearly, thoughtfully, and honestly will help you understand the reasons to convert a desktop application into a web application and give you confidence moving forward with your transition plans.

### Top 5 Performance Issues with AngularJS

What’s going on with AngularJS? Is it high time to seek Angular upgrade services? Well, the difficulties with AngularJS keep growing. Although 20.39% of worldwide developers prefer the AngularJS framework for frontend web application development, the tech stack has a market share of 1.5% with slightly over 300,000 customers. The open source tech stack was once ideal for building big websites as it allowed developers to write clean and robust code and reuse the same to duplicate similar functions. 



However, AngularJS has been around for a while. A new breed of frontend technologies has risen, and their superiority exposes AngularJS performance issues. But are these glitches something to worry about? This article explores 5 performance issues in AngularJS, their risks, and alternative technologies that offer greater security and efficiency. Keep reading to stay updated. 



What’s Wrong with AngularJS Framework?



AngularJS is a complicated framework that’s not only hard to learn but also lacks proper documentation, making it hard for developers to read or understand what’s going on in the frontend. Misko Hevery originally developed the framework in 2009 while working on a part-time project for Brat Tech LLC. 



A year later, Google launched the first version of AngularJS, dubbed Angular 1.x. As a free-to-use JavaScript framework, AngularJS became instrumental in building dynamic web pages of frontend applications until the entry of ReactJS. Stiff competition from the new framework culminated in the launch of Angular 2 in 2016. Although Angular 2 was a complete rewrite of AngularJS, the development team retained the JS name sans to avoid confusion. 



Since then, there have been several iterations of the framework to keep up with emerging tech. However, despite these improvements, AngularJS 'end of life is imminent. AngularJS was deprecated because web applications built on AngularJS will have inferior security features over time, thanks to the exposed loopholes that go unfixed. Cybercriminals often exploit these loopholes to access web apps and run their malicious code.



5 Prevalent AngularJS Performance Issues 



While AngularJS is a powerful framework for open-source web development, it may not be that effective when a big website is involved. Unless you know how to implement the framework’s best practices, AngularJS difficulties will persist and eventually take a toll on your web app’s user experience. That said, here are the 5 prevalent problems with Angular JS performance. 







1. Code organization 



One of the main technical problems with AngularJS is proper documentation during development, which can lead to poor code organization. Logical code organization is critical in big AngularJS websites as the practice helps developers keep track of important items and introduce more controllers and services as the code base grows. Without proper code organization, the directory structure may be bloated as more files are added. 



2. Debugging code 



Debugging is an inevitable, complex process for any web app development project. But, be that as it may, debugging is more complicated in web applications that run on AngularJS, thanks to the framework's large-sized directory structure. In other words, the code is presented in one big chunk, making it hard to visualize it in sections and spot troublesome issues. Fortunately, this is one of the performance issues in AngularJS that can be addressed with the AngularJS Batarang extension.  



3. Loading JavaScript files 



Typically, a large AngularJS project requires several JavaScript files, which usually load one after the other. This means every JavaScript file is dependent on the other one to load, causing a drawn-out negative effect that hinders performance when loading files upfront in the shell page. The only way to mitigate this dependency is by uploading JavaScript files dynamically so that they can load as users request them—you’ll need RequireJS to achieve this functionality. 



4. Integrating third-party libraries 



Integrating libraries from a third-party to achieve desired business outcomes is a standard practice in any web development, not just applications powered by AngularJS. However, changes in the DOM when integrating third-party libraries can cause performance issues with AngularJS. The same issues can also arise when you return values through Ajax calls, making it hard to manually acknowledge the changes unless you initiate a $digest loop. 



5. Lazy loading 



Lazy loading is critical as it helps shorten the loading durations of a website, especially a large application that runs on AngularJS. Unfortunately, the framework’s development team doesn't support lazy loading, a function that facilitates JavaScript files to load properly as the code base grows. Besides employing ReactJS alongside another open-source framework that supports lazy loading, you can do minification to enhance page speed. Alternatively, you can migrate to Angular, where all components load at once under a single Page Application (SPA). This might help you address some of the performance issues of AngularJS. 



What Are the Risks of Staying on AngularJS?



Google announced a one-time 3-year Long Term Support (LTS) for AngularJS on 1st July 2018. Following this announcement, no new updates have been released since the end of 2021, given that the LTS was extended by six months due to the Covid-19 pandemic interference. Despite being privy to this information, some organizations still run their website apps. 



Are there any risks with this approach? Well, there are several risks and AngularJS performance issues, including: 



Security risks 



The biggest risk of staying on AngularJS is safety, given that Google doesn't provide new security patches after halting its LTS. In other words, websites that run on this framework are highly susceptible to new attacks as cybercriminals exploit emerging and previously unresolved loopholes. 



Compatibility issues 



AngularJS is a legacy technology, and its end of life is imminent. Integrating your app with new technologies will be an uphill task, if not impossible. This includes micro frontends, which may not be supported at all, or CI/CD pipelines that use innovative packaging tools like Gulp. Moreover, you might also experience browser compatibility issues when search engines evolve. 



Diminished performance and agility 



AngularJS was a ground-breaking framework during its launch back in the day. However, like any other technology, its weaknesses and design flaws have inspired the rise of new UI frameworks that have far way greater performance and agility. 



Skilled resources 



As the performance and agility of your web application diminish, it will also be harder to attract and retain talents to maintain your code in the coming days. While developers might have the skills to work around AngularJS, nearly all of them are fascinated by web development projects that expose them to new tools and technologies. 







Community support 



Another risk that also exacerbates the technical issues of AngularJS is the community support that keeps shrinking over time. During the heydays, the framework enjoyed massive support from a large and vibrant developer community. Today, the community doesn’t address new security concerns or technologies. Moreover, a majority of community-centric third-party libraries are not supported today.



Superior Alternatives to AngularJS



Innovation is fast-paced in the software development industry, and it was just a matter of time before the successors of AngularJS gained traction following its drawbacks. AngularJS alternative frameworks aren’t just mobile-friendly but also introduce simpler code that can be duplicated without rewriting. 



By ignoring the possible upgrades and failing to implement AngularJS migration, your web app will be exposed to risks and lag in terms of the performance and agility of modern UI frameworks. There are various options that you can resort to escape the problems with AngularJS performance, including: 




React for building user interfaces and maintaining the frontend ecosystem. On top of a virtual DOM, the framework offers a one-way data binding for code stability, is SEO-friendly, and has a dedicated mobile solution known as React Native. 



Vue.js is a framework that's easier to learn than AngularJS and also comes with a virtual DOM. It has a Command Line Interface (CLI) for speeding up development, as well as a data binding feature for assigning values to HTML. 



Backbone.js is a lightweight JavaScript library for creating single-page applications effortlessly. The technology comes with multiple building blocks, including events, models, and views, as well as extensive documentation with over 100 extensions. 




Alternatively, you can upgrade to Angular to address the technical issues with AngularJS. This alternative is a great option if you want to upgrade gradually and harness top-flight Angular features like TypeScript, CLI, and ngRX, among others. Moreover, you can simplify the upgrading process, depending on the underlying app to save time when rewriting the code.



That said, here are the key advantages of Angular migration: 




A host of intuitive features, eliminating the need to leverage endless third-party frameworks to achieve basic app functionality.



A fully-fledged and responsive framework that gives you a functional alternative for creating a service, module, or component. 



Based on Typescript for greater code organization and readability, making it easier to identify and remediate bugs. 



Cross-platform compatibility. 



Seamless app performance and constant updates.

### 5 Tips for Effective Documentation of Legacy Code

Legacy code is typically inherited from previous developers and is difficult to update unless you want to risk breaking the essential components in your program. Another inherent trait of legacy codes is that they either have low-quality documentation or lack the same altogether, something that can impede your legacy system architecture improvement process. 



This article takes an in-depth look into the documentation of legacy code, why it's necessary, basic requirements, and an overview of the whole process. Keep reading and get tips on how to write legacy code documentation. 



Why Document Legacy Code?



Why document legacy code, and why are legacy systems still used, yet there are numerous new technologies, probably with higher performance? Legacy code needs to be documented because it's hard to replace, especially if it drives core business functions. Moreover, legacy systems rely on 1 to 2 developers who originally coded it. If these people leave your organization maintaining the legacy code can be challenging and it might eventually crash. 



Lack of software documentation will most likely result in your team losing focus, underestimating the workload, or building a white elephant. It will prove very challenging, if not nigh impossible to maintain the system when you finally hire a new team. 




“It really doesn’t matter what you build if no one can figure out how to use it.”  
Tim Smith, Chef Product Manager



On the other hand, documenting a legacy codebase gives your current programmers great insights into the building blocks of your system architecture. This comes in handy when upgrading legacy systems with new features or correcting failed components. At the same time, businesses modernize legacy systems to tap into new frameworks and technologies that help you build and deploy digital solutions faster. 



Requirements for Legacy Code Documentation 



The process of legacy software documentation starts with understanding what the application does. For instance, which business challenges is it geared to solve? This information should be well described in a written document, as well as an overview of how the system components interact with each other. 



After that, you should map out all the links to the system to understand the sources of your input and the destination of the outputs. Fulfilling this requirement will also help you account for external service providers when preparing documentation of legacy system. 



It’s worth noting that you might have a diagram representation in some instances before you start to document the architecture of the application. This is especially true if you want to prepare an architecture document of a complex system. A diagram of the system’s phases will give you a better overview of the legacy code documentation process. 



Overview of Legacy Code Documentation Process



The process of creating documentation of legacy code can be quite complex for the uninitiated, especially if an enterprise-grade system is involved. That said, here is how to document a legacy code project. 



Conduct a system overview 



Evaluate a legacy system to determine the initial perspectives of the system before you start documentation. Critical factors to consider at this stage include:




Architecture overview: Create a diagram representation highlighting all the components and how they interlink with each other. 



Component list: List all the components on a table alongside their respective name, purpose, service provider, or version number 



Functional overview: Describe what the system does briefly and the business problems it intends to solve. 



External interfaces: Create another list of all the third-party applications that your system integrates with.




Document other elements 



Other elements you might consider when creating a software documentation depend on whether they are relevant to your project or useful to the development team. At the very list, documenting a project might include:




The coding standards inspired by the previous developers.



A reference for domain-specific names.



Non-functional requirements, such as performance, compatibility, or deployment protocols.



Agreements with external platforms or applications.




Automate 



The next step of documenting a legacy codebase is automation. Automation helps you save time and costs, especially if you're going to rewrite a code in the future. For instance, you can leverage emerging tools to generate a website from your sum-up legacy application documentation. Similarly, you can also generate diagrams of your system’s parts and automate coding standards in the future. 



Maintain the documentation 



The last step of documentation of legacy systems is ongoing maintenance. While automation will complete most of the work, some maintenance tasks will require manual involvement. Maintenance will make it easy for your team to refactor legacy code. 



5 Tips for Creating an Effective Documentation of Legacy Code



Now that you understand the benefits of legacy code documentation, what are the best practices? Documentation while working with legacy code can be pretty challenging to both junior and senior programmers. Here are 5 tips for efficient documentation with legacy technologies.  



Start small and scale gradually 



One of the reasons for legacy code documentation is to minimize mistakes or risks that might impede upgrades in the future. Starting slow ensures that you counter-check every section of the code so that you don’t get overwhelmed by multiple rewrites when refactoring legacy code. 



Document call hierarchy 



Documenting a call hierarchy will help you track down how a specific system part works, especially when working with a legacy time code that is relatively long. This works by highlighting a specific function and listing down the subsequent calls that it makes sequentially. 



Double-check any assumptions 



Making assumptions about what a system's component does is synonymous with team leaders who love taking the easier route of project management. Inasmuch as this can save you time, it can also culminate in technical debt. Double-check your assumptions to repay this debt before it yields "interest" in untenable risks.  



Testing is paramount 



Testing is obvious as one of the best practices of code documentation but is worth emphasizing. Conducting both unit and function tests will come in handy when cleaning up code, as this practice will reveal bug issues. You can set up logging to achieve the same objective when test cases are consuming too much of your time. 



Incorporate DocOps in your strategy 



You can also implement DocOps practices that extend to automation and integration of software documentation processes across your entire organization — from product and engineering departments, to support and technical writing teams. Do your research and find the best tool for documentation as this approach fosters collaboration and continuous improvement for effective documentation of legacy code.

### Azure Migration Strategy in 6 Steps

Migrating on-premise databases, VMware, and applications hosted on other cloud services, e.g., Amazon Web Services (AWS) or Google Cloud to Azure is a significant undertaking. Yet many companies make the switch without realizing all of the potential pitfalls.



While understanding the importance of having a strategy for businesses to enjoy the cloud benefits, migration without a strategy can be costly and may come with problems. According to one survey conducted, 74% of respondents moved at least one app back from the cloud to their infrastructure. The key drivers for this decision included poor performance and security (52%), temporary nature of cloud deployments (40%) and regulatory issues (21%).



If you’re new to building and deploying Azure applications, we're here to help! We developed this Azure migrate step by step guide to walk you through the steps of a successful migration.



What is Azure Migration?



Azure migration is the process of moving on-premise or cloud workloads from other cloud providers to Azure. Usually, the goal behind this transition is to reduce cost and complexity while improving agility, security, and scalability. It’s also the case of multicloud technology that comprises public, private, and hybrid clouds or a combination of clouds to meet specific business workloads.



Additional benefits of migrating to Azure include:




Taking advantage of Azure’s unique capabilities, such as serverless computing, container support, and artificial intelligence services. 



Azure offers a comprehensive set of built-in migration tools and services that can help simplify the migration process.




5 Reasons to Migrate to Azure as Your Primary Cloud Provider



Here’s a brief breakdown of the main reasons to migrate servers to Azure: 




Cost savings



Scalability



Increased security and compliance



Improved performance 



Accessibility from anywhere in the world.




1. Cost savings



Moving to the cloud can be expensive at first. But over time, businesses save money by not having to manage their own physical servers. On-premise server running costs go for the thousands (can cost anything from $1000). 



This cost can be broken down into:




Hardware costs - $1000 to $4000



Software costs - $500 - $4,000 for a Windows server



Developer and maintenance costs - $200 to $900 for SQL Server



Customer support - $10 - $20 per hour and a retainer worth $1000 per month




Microsoft Azure offers a cost-effective pay-as-you-go model. Businesses can pay for the resources that they need when they need them. Additionally, there is no need to purchase additional server hardware upfront.



2. Increased security & compliance



With Azure, your company’s sensitive data is kept safe by several layers of protection, including:




Advanced 256-bit AES encryption.



Azure Multi-Factor Authentication (MFA).



Azure firewall.



Identity management systems.




These systems keep your customer data safe from potential malware and unauthorized access. Azure also meets compliance certifications for companies in highly-regulated industries such as healthcare, finance and banking. 



3. Easy integration & scalability



Microsoft Azure allows for easy integration with existing applications and services so that businesses can quickly migrate their workloads without disruption or downtime. And as your business grows over time, Azure scales up with you.



That way, you never have to worry about depleting processing power in a resource demand surge.  



4. Improved performance & reliability



Because everything runs on remote servers hosted by Microsoft instead of on-premises hardware owned by your organization, there is less maintenance required from your end. 



Migrating to Azure moves workloads and services closer to the customer, which, in turn, reduces latency. Together with Azure’s bigger storage capacity, your existing applications are able to deliver faster solutions to your customers.



5. Accessibility anywhere



Microsoft Azure’s cloud applications can be accessed from virtually anywhere in the world at any time. This makes virtual collaboration easier than ever for remote teams.  



Global accessibility fosters efficient operations. Businesses are no longer tied down by physical server locations or geographic boundaries.



What to Consider Before Migrating to Azure Cloud?



A successful lift and shift migration to an Azure environment requires careful planning beforehand. This can be achieved by taking into account potential costs associated with licensing and usage fees, security compliance requirements, scalability limitations, and maintenance/support options.



Determine your goals



Successful migration to Azure begins with defining the goals for your project.



What do you want to achieve by migrating your workloads to the cloud? Are you looking for cost savings or performance improvement? Do you need scalability or flexibility? Sometimes cloud migration may not be the answer to what you need — and may not be worth it. Before you commit, weigh the pros and cons of the migration.



In any case, your cloud migration goals should be aligned with the company’s overall goals.     



Costs & Licensing 



Costs associated with cloud migration can vary greatly depending on your business needs. Consider looking into any licensing requirements for hosting certain software in the cloud. Thankfully, Microsoft provides a detailed pricing guide for all the costs and licenses for Azure migration tool licenses.



Support & Maintenance



Microsoft provides 24/7 support for its Azure services. Still, it is important for businesses migrating to the new platform to do their due diligence and understand the terms and conditions prior to the migration. Also, think about downtime (cutover) — the time when the service won't be available. You need to have backup to minimize the risk of data loss.



Research the support options offered by Microsoft partners or third-party cloud migration services that specialize in providing assistance with cloud migration. If any issues arise during or after migration, reliable support contacts will already be established beforehand.



Azure Migration: Strategy, Assessment, and Planning



As we advance deeper into our Azure migration guide, it’s important to point out that a successful migration narrows down to three activities: strategy, a step by step Azure migrate assessment, and planning. 















Strategy 



A well-thought-out strategy covers every aspect of the migration process. In your strategy, take into account the following: 




Budget



Available personnel (in your internal or external IT development team)



Availability of Azure resources (Azure Virtual Machines, Azure Virtual Network resources, Network security groups, databases, etc.)   




Next, create a timeline that allows for realistic milestones throughout the process. 



Assessment



Are your applications suitable for a cloud environment? Will the migration bring any benefits to the organization? Regardless, you need to get in touch with all the stakeholders to keep everyone on the same page prior to the migration.



Your assessment should include: 




An analysis of your current infrastructure and applications.



Potential challenges or issues that may arise during the transition. 



Current applications that may not be compatible with Azure.



Applications that may need modifications to function properly in the cloud environment. 




Microsoft’s Virtual Machine Readiness Assessment tool assesses your current infrastructure. It generates a report about what workloads can be moved and any issues that may arise during migration. 



For a more robust solution, we recommend our full-scale legacy software and assessment services where we aim to achieve understanding of the legacy application, its security and performance status prior to the migration.



Azure Migration Planning



During this phase, you will need to:




Determine which among your several tools and applications should be migrated first based on their importance, business priority, or complexity



Develop a roadmap for the entire process. 



Consider data storage options as well as backup strategies in case something does go wrong during the transition. 




It is also important to set up clear expectations with stakeholders so that everyone involved understands their role in the process. 



6 Azure Migration Steps You Must be Aware of



At ModLogix, our Azure migration step by step process as usual starts with careful planning and attention to detail. 















With that in mind, let's take a look at the six main Azure migration steps:



Step 1: Planning



Before embarking on any Azure migrate project, it’s important to evaluate the current infrastructure to determine its suitability for migration. Next, the migration should be aligned with your business goals, objectives, and your business processes.



For instance, are you looking for increased scalability? Or are you looking for improved performance? 



Once we have identified your desired outcome, it’s time to jump on to the next step. 



Step 2: Identify Your Resources 



Resources in our context refer to the time and material resources will be required to make the migration process successful. What to assess: 




Whether additional hardware will be added to the on-premises data center.



Available backups and disaster recovery. 



The data security measures. 




Finding answers to these questions beforehand gives the sufficient time and information to develop a successful cloud migration strategy. 



Step 3: Assess Your Existing Infrastructure 



The third step in fulfilling your Azure migration checklist is to check the state of your existing infrastructure. 




What technologies are currently in use? 



Are there any potential compatibility issues that need to be addressed before migrating to Azure? 




Taking stock of the current state of your IT environment will give you a better understanding of what changes need to be done before the migration. 



Step 4: Develop the Migration Plan



Once all the required resources have been identified, it’s time to develop a detailed plan for executing the actual migration process. This includes creating timelines, assigning tasks, and reviewing processes and procedures - all with the goal of ensuring success at every stage. 



A clear plan in place before starting any migration work will help ensure that all steps are completed on schedule and on budget. 



Step 5: Monitor & Test During Migration   



After developing the migration plan, it’s important to monitor progress during each stage of execution. We thoroughly test everything before going live with new applications or services running on Azure cloud architecture. 



This is crucial for identifying any potential issues prior to launch or roll-out so they can be resolved quickly and efficiently. At the same time, we focus on minimizing downtime and loss of data integrity.   



Step 6: Review & Update Post-Migration   



The final step in executing an effective Azure migration is reviewing all systems post-migration. Occasional updates will be necessary. You can update the newly migrated code with the latest patches if needed. This ensures that all systems are working properly after being migrated and are able to perform optimally in their new environment. 



That sums up the most important items that we include in our template of Azure cloud migration plan. 



Plus, don’t forget to stay up-to-date with the latest updates from Microsoft; businesses can maximize service levels while minimizing risk factors associated with cyber threats or overpayments. 



Challenges of Azure Migration Companies may Face



Migrating to Microsoft Azure can provide businesses with numerous benefits but also comes with its own set of challenges that must be addressed before moving forward with any Azure migration project plan. 



Data security concerns must always be at the forefront when transferring information from an existing system into a new platform. Additionally, understanding the associated costs as well as potential compatibility issues are key factors in ensuring that the migration goes smoothly. 





Data Security Concerns 



One of the biggest challenges when migrating to Azure is ensuring that all data remains secure throughout the process. Transferring data from an existing system to a new platform can create vulnerabilities. 



Azure active directory grants protection against 99.9% of cyber attacks. However, access control policies should still be implemented so that unauthorized users cannot access sensitive information. 





The Cost of Migration 



Before beginning the process, estimate the cost of migration — consider both the upfront and ongoing expenses that may be associated with using Azure services. 



Many companies have difficulty estimating how much storage space they will need for their data or how much bandwidth they will require for their applications. This automatically leads to overspending on unnecessary services or under-utilizing available resources. 





Compatibility Issues



Dealing with compatibility issues between existing systems and the cloud-based environment is an uphill task. Depending on your current system setup, you may need to make changes or upgrade large chunks of the application code in order to take full advantage of what Azure has to offer. 



What’s more, certain software applications may need to be rewritten or refactored to work properly in a cloud-based environment. This could add significant time and cost expenses to your project budget. 



How Much Does Migration to Azure Cloud Cost?



The cost of migrating to Azure will depend on several factors, such as the size of your business workloads, the number of users, and the complexity of your current environment. In general, there are several costs associated with migrating to the cloud, including licensing fees, consulting services, hardware costs, and software costs. 















You can find a pricing calculator in your Azure portal to estimate the total cost of the products you wish to access, including:




Azure SQL Database



Virtual Machines



Azure Functions



App Service for web and mobile



Azure Cognitive Services



Storage Accounts




At ModLogix, we can help with Azure cost optimization by taking into account the appliances for high traffic demands, region, and system resources.

### Why Update .NET Core 2.1 to 3.1 Make Sense?

When Microsoft originally released .NET Core on June 27, 2016, it immediately garnered popularity among software developers. Today, it is the technology of choice for 27.9% of professional developers. The .NET Core 3.1 version was released not so long ago in December 2019, and includes a number of new features and improvements. 



This version is a long-term support (LTS) release. This means, any updates and support will be provided to the new core for a considerable amount of time — in this case, up to December 2022. 



If you are still using the old .NET Core and you want to take full advantage of the new framework and stay on top of technology developments, then you should seriously consider making the update .NET Core 2.1 to 3.1.



If you’re looking for reasons why you should upgrade your .NET Core to version 3.1, this article contains important information about this new upgrade. You'll learn the differences between version 2.1 & 3.1, and this information will help you to make an informed decision.



What is the Difference Between .NET Core 2.1 and .NET Core 3.1?



.NET Core 2.1 is an earlier version of the robust framework that allows you to create UI, Web APIs, and other cloud-based applications. It was released on May 30, 2018.



.NET Core 3.1 is the more recent release of Microsoft's free, cross-platform, open-source development platform for creating a wide range of apps. It was released on December 3, 2019.



So what's the difference between .NET Core 2.1 and .NET Core 3.1? For starters, .NET Core 3.1 is faster and more efficient than its predecessor and will push your app to new levels of scalability, performance, and security. 



It also delivers low-memory support for JSON and tiered compilation that optimises startup time. Windows desktop application development is also supported, as well as considerable speed enhancements across the board.



All in all .NET Core 2.1 to 3.1 upgrade comes with a new set of features and improvements that make it easier to build high-quality applications.



Why Migration from .NET Core 2.1 to 3.1 is Relevant?



Even though Long-term support (LTS) for .NET Core 3.1 is ending in a few weeks, that does not mean you should not upgrade from .NET Core 2.1 to 3.1. 



There are tons of reasons to migrate from .NET Core 2.1 to 3.1. Some of the top reasons include:



1. Get the benefits of Performance Improvements



Possibly the most important reason to migrate 2.1 to 3.1 .NET Core is that the 3.1 release brought a lot of performance improvements to the table.



It includes all the latest updates and security fixes that were missing in the previous major version, and you get the benefit of these improvements without having to change any of your code. For example, .NET Core 3.1 has an average response time of 1.6ms. This is a whopping improvement of 12.5% compared to .NET Core 2.1.



.NET Core 3.1 also includes support for the latest Windows 10 releases, as well as support for creating C++/CLI projects.



2. Docker optimizations



Docker containers are a popular way to package and deploy applications. They're easy to use and offer a consistent ecosystem for development, testing, and production. .NET Core 3.1 has been improved to work better with Docker containers. 



The garbage collector and thread pool have been optimized to operate significantly better when a container is set for restricted memory or CPU.

The changes make it easier to create containers that are more predictable and efficient. And the new capabilities make it easier to deploy and manage .NET Core applications in containers.



3. Cross-platform diagnostic tools



Diagnostic tools in .NET Core 3.1 have been updated with new .NET runtime capabilities that make it easier to carry out cross-platform diagnostics in order to identify and address performance issues.



This helps you identify why your application fails to start or stops working after a while. You can get information on the health of your application, why it is behaving abnormally, and reasons for crashes. These results will come in handy when troubleshooting problems related to race conditions or deadlocks.



4. Faster & smaller SDK



With .NET Core 3.1, the .NET Core SDK is substantially smaller. This is because the SDK's construction was altered by shifting reference assemblies, frameworks, and templates to purpose-built "packs". Previously (including .NET Core 2.2), the SDK was built from NuGet packages, which included many artefacts that were unnecessary and took up a lot of space.



5. Easier to move to .NET 5 and above



.NET 5 was launched in November of 2020, and with it, a whole host of new features and improvements. But if you're still on .NET Core 2.1, upgrading to .NET Core 3.1 is a great way to get started with the latest versions. 



Not only will it make it easier to move to .NET 5, and from there upgrade to .NET 6, 7, and 8 when released, but in the meantime, you'll also get access to all the new features and performance improvements in .NET Core 3.1.

6. Support for Raspberry Pi and Linux ARM64 chips



.NET Core 3.1 supports Raspberry Pi and Linux ARM64 chips. These chips make it possible to develop IoT applications using the remote Visual Studio debugger. Using the new GPIO API, you can listen to sensors, publish apps that read sensor data and display messages or graphics.



Cases When Upgrading .NET Core 2.1 to 3.1 Makes Sense



If you're using .NET Core in your projects, then you know that it's constantly evolving. And with each new release, there are always new features and enhancements to take advantage of. So when does it make sense to switch up from .NET Core 2.1 to 3.1? 



When you need:




New features and enhancements - As we mentioned, with each new release of .NET Core, there are always new features and enhancements. Upgrading to the latest version ensures that you're always taking advantage of the latest and greatest.





Improved security - Security is always a top priority for .NET Core developers. And with each new release, the security of .NET Core is improved. So upgrading to the latest version helps to keep your apps secure.





Increased performance - .NET Core 3.1 is faster and more efficient than the older .NET Core, thanks to its modular design and improved garbage collection.





Cross-platform compatibility - .NET Core 3.1 can be used on Windows, Linux, and macOS, so you can develop for any platform you need.





Focus on desktop development - If you're primarily focused on desktop development with .NET Core, then you need to upgrade 2.1 to 3.1 .NET Core. It includes improvements to the Windows Forms and WPF libraries. These improvements make it easier to create rich, interactive user interfaces.

Key Problems in Upgrading .NET Core 2.1 to 3.1 Version



If you're migrating .NET Core 2.1 to 3.1, there are some problems you should be aware of. 



One example is Microsoft.Extensions.* libraries received a significant version boost to 3.0.0 in .NET Core 3.x. Additionally, NETstandard 2.0 and NET Core 3.0 are now multi-targeted. Unfortunately, 3.0.0 extension libraries cannot be used in ASP.NET Core 2.x projects. If you do, you will receive an error.



Additionally, according to the NuGet package resolution rules, when you reference your library in an ASP.NET Core 3.0, the 2.x dependencies of your library will be immediately updated to the 3.0.0 versions. Therefore, you should avoid automatic updating because a big version bump usually results in breaking changes. Code built for one major version of a dependency won't always function properly when used with another major version of the dependency.



Last but not least, in version 3.0.0 of Microsoft.Extensions.Options library, Add, Get, and Remove methods were removed from OptionsWrapper<>. A MethodNotFoundException will be thrown at runtime if you use these methods in your library.

### SQL Server 2022 Release Date and New Cloud Capabilities

When will SQL Server 2022 be released? Microsoft has already announced the general availability (GA) of SQL Server 2022, the latest release of its flagship database system.



A private preview of SQL Server 2022 was first announced in early November 2021, followed by the SQL Server 2022 public preview in May this year. The GA version was then released on Wednesday, November 16, 2022.



SQL Server 2022 is a significant release that delivers improvements over previous versions, including improved performance, security, and availability. So if you are currently running an older version of SQL Server, now is the time to upgrade. 



Here is an overview of this latest major update, SQL Server 2022 new features and why you should be moving to SQL Server 2022 (16.x). You can also find comprehensive details on what to expect in this new release on the official Microsoft SQL Server Blog.



SQL Server 2022 vs 2019: What's the Difference?



The most recent major SQL Server release was version 2019, and as always, Microsoft keeps improving the SQL Server engine's core with each new iteration. 



Nowadays, virtually all SQL Server innovations begin in the Azure cloud before moving to the on-premises editions of the database server. But with this update, new features have been included that will boost the scalability and increase the skills of data professionals. 











The migration path is really brimming with innovative methods for quickly updating your ecosystem and bringing it up to speed with the most recent versions. These new features will help you to convince management to migrate.



What’s New in SQL Server 2022?



The following are just some of the SQL Server 2022 new features that are improved or introduced in SQL Server 2022 (16.x).



1. Business continuity through Azure



The link functionality in Azure SQL Managed Instance and SQL Server 2022 are completely integrated to guarantee uptime. With this new option, you have access to a PaaS environment that is used for disaster recovery/ business continuity and can act as a backup for your primary on-premises SQL Server, making it simple to switch to it in the event that the primary server goes down.



Everything you need to know about the cloud journey. Guide to Cloud Migration Strategy Process 



2. Seamless analytics over on-premises operational data



The latest version of SQL Server supports automatic connections to Azure Synapse Link to enable real-time database analytics.



With Synapse Link, analysts can perform near-real-time analysis and perform hybrid transactions and analyses without compromising operational efficiency.



Synapse allows you to combine data from a wide range of sources regardless of size, scale, or format. You can then use Azure Machine Learning, Power BI, or Spark to do advanced analytics on everything. This will have little or no effect on the performance of the source database.



3. Visibility over your entire data ecosystem



Purview, a data governance solution by Microsoft, now integrates with SQL Server 2022 to help you discover data more efficiently, giving you visibility over your entire ecosystem.



As a result of this integration, you can automatically and at no cost scan your on-premises SQL Server to collect data and classify them using built-in and customized tags as well as Microsoft Information Protection sensitivity labels



The Azure Purview console also allows you to configure and control specific access rights and privileges for SQL Server.



4. Achieve your security and compliance goals using the defender for SQL plan



Microsoft SQL Server 2022 provides improved security for your SQL servers using the Defender for SQL plan. 



Defender for SQL plan requires SQL Server Extension for Azure to be activated. It contains functionality for finding and mitigating possible database vulnerabilities as well as monitoring unusual activity that might signal a threat to your database environment.



More information regarding Defender for SQL's ability to safeguard your whole database estate across on-premises, hybrid, and multi-cloud systems can be found in this Microsoft’s article.



That’s not all. In SQL Server, the new Ledger feature provides a history of how data has been modified over time. This detects when someone has tampered with it and will come in handy for internal and external audits. 




Ledger allows participants to verify the integrity of the centrally housed data.
Asad Khan, director of program management for Microsoft Azure.



This makes it the most secure database over the past 10 years.



5. Performance improvements



SQL Server 2022 now includes a number of performance features and improvements, such as Query Store and Intelligent Query Processing.



SQL Server uses Intelligent Query Processing to create superior execution plans and even multiple execution plans based on the parameters provided at runtime.



Query Store's read replicas feature and query hints, which improve performance and mitigate issues without requiring real code modifications.



6. Pay As You Go billing model



Besides Azure-connected functionality, this release of SQL Server includes automated technical assessment at no additional charge as well as a Pay-as-you-go (PAYG) billing model for SQL Server via Azure Arc, Microsoft's cloud and on-premises resource management platform.



This means that on-premises users can now take advantage of cloud-enabled billing for special cases or to manage consumption increases by connecting to Azure Arc, a part of the SQL Server 2022 setup process.



Using SQL Server Pay-as-you-go billing feature, customers can:




Choose between perpetual or consumption-based SQL Server licensing.



Enjoy improved cost-savings for Enterprise Edition and Standard Edition by eliminating upfront license payments. Customers pay only for what they use.



Access consistent billing model for all SQL workloads on any cloud or hybrid deployment, regardless of customer location.




7. Hardware integration



To improve batch mode performance, SQL Server 2022 (16.x) uses new hardware capabilities, particularly the CPUsAVX-512 instruction set.



AVX-512 is a set of instructions that are designed to improve performance when processing large amounts of data. The instructions are used to vectorize operations, meaning that they can be executed on multiple data points simultaneously. 



The performance improvements offered by the AVX-512 instruction set are substantial when compared to older versions. This can dramatically improve performance for certain types of workloads.



An additional feature named Integrated Acceleration & Offloading enables certain SQL Server workloads to be offloaded to hardware devices. For now, it works only with Intel's QuickAssist Technology (QAT), which allows backups, restores, and compressions to be offloaded. 



8. Data visualization with Polybase



Data virtualization is a key target for Microsoft with SQL Server and this latest version has been designed to make use of Polybase for data visualization. 



Using Polybase, users can access remote sources, query data across different locations, virtualize data, and use REST APIs, all in SQL Server 2022. With this feature, users will be able to access data from a variety of sources, including Hadoop and other big data systems.



How to Upgrade to SQL Server 2022?



Would you like to leverage the benefits of this new system? Then it's time you level up. But how do you upgrade to SQL Server 2022?



Any SQL Server instance may be easily upgraded to SQL Server 2022, with the exception of SQL Server 2008 and SQL Server 2008 R2, according to the SQL Server 2022 compatibility levels. You'll need to do either a migration or a side-by-side upgrade for SQL Server 2008 and SQL Server 2008 R2.











One common way to upgrade is by using the installation wizard. This provides a standardized feature tree for upgrading SQL Server components to the most recent version of SQL Server. Before getting started, ensure that you meet the SQL Server 2022 system requirements.











The older version of Microsoft SQL Server will be overwritten and removed from your computer when you upgrade it. It is, therefore, crucial that you back up the databases and other items connected to the old SQL Server instance before upgrading.



For the most part, upgrading to SQL Server 2022 is easy and straightforward if you know what you are doing. Microsoft has also written a detailed step-by-step article on how to achieve this.



If, on the other hand, you are looking to upgrade from SQL Server 2008 and SQL Server 2008 R2 or you are worried about making a mess of your database, then you need our legacy system upgrade services at ModLogix.

### Azure Cost Management: How to Reduce Your Cloud Spendings

The cloud has changed the way we do business. We no longer have to worry about IT, networking, and backup infrastructure back to the days when mainframes run the show. Now, we can offload all that to cloud providers like Microsoft Azure, Google Cloud, or AWS. 



But, the trouble is, if you don't know what you are doing, you will end up paying for resources you don't use or need.




One of Gartner’s key findings in managing and optimizing public cloud costs states, “focusing on efficient use of cloud services brings immediate and tangible financial benefits. Unfortunately, most organizations are unprepared to profit from this savings opportunity and are likely to overspend.”




Poor cloud management techniques like overprovisioning of resources, unutilized assets, poorly optimized data storage, lack of automation, and a lack of central IT governance are some of the common causes of cloud overspending and double the cost of maintaining legacy systems. And according to Gartner, mistakes like these will cause 80% of businesses to overspend by 20 to 50% in cloud adoption.











If you are looking for ways to reduce your cloud spending in Azure cloud, cloud cost management Azure solution and industry best practices can help you do just that. In this guide, we will answer some of the Azure cost management questions that have been bothering you.



What is Cost Management in Azure?



Cloud adoption can help you streamline your business workloads and improve technical performance and capacity. This technology is also supposed to reduce the costs needed to manage organizational assets. You simply select the services that suit your business needs, and the resources you use are billed monthly.



Sadly, many companies overspend on the cloud. 



According to Gartner projections, end-user spending on the public cloud is expected to hit $600 billion by 2023. This is a whopping 46% up from $410.9 billion in 2021. 





In another study, it was discovered that enterprises are currently overspending on cloud services by more than $8.75M, due to stringent pricing and poor data management tools. This is where Azure cost management can help.





Azure Cost Management is a service that helps you optimize your Azure spending and get more value from your Azure subscription. With Azure Cost Management, you can:






Understand your Azure costs



Monitor your Azure costs



Manage your Azure costs




With this tool, users are able to view at-a-glance the costs associated with each resource in their organization, as well as the associated Azure Marketplace products, enabling them to adopt a more efficient and effective cloud strategy. 



By integrating Azure Cost Management with Azure Advisor, you can get personalized cost recommendations based on your usage patterns. 



Cost and usage data for your Azure resources can also be accessed programmatically using an Azure Cost Management API. All-in-all, the tool could help you reduce cloud spending by up to 34%.



But Azure Cost Management and Billing tool is not the only way to optimize your cloud adoption spend. 



5 Glaring Signs You Need to Reduce Azure Costs



Are your Azure costs getting out of control? If so, you're not alone. Many businesses find that their Azure costs are taking a big chunk out of their budget - but they don't seem to know where the problem is. The following five signs indicate you need to take action to reduce your Azure costs.











1. Underutilized Resources



One of the most common mistakes made by organizations that have moved their workloads over to the cloud is underutilized resources. 



Underutilized resources include virtual machines (VMs) that aren't being used to their maximum capacity or storage accounts that are oversized for the amount of data they hold. It could also mean that you have too many VMs in your account, some of which are idle and contributing to your cloud spending waste. 



If you don't know which of these applies to your situation, use Azure Advisor to see how much space is currently being wasted by unused resources on your Azure account.



2. Overprovisioned and Oversized VM Instances



Many people make educated guesses and end up overestimating their workload requirements, resulting in purchasing larger VM instances than they need. 



When you overprovision a VM instance, it means that there is more memory allocated to that instance than what the VM requires. It can result in wasted resources and cause unnecessary costs as well.



As part of your Azure cost optimization strategy, you should rightsize or downsize VMs when they are overprovisioned. It is better to start with small VM instances in Azure and scale them as your IT requirements grow.



3. Not Monitoring Azure Data Box Data Transfers



The data box feature of Azure allows users to transfer large amounts of data between regions without incurring any downtime or interruptions. However, egressing data between regions can be expensive, so this feature needs to be monitored properly.



Follow these tips to optimize data transfer to and from Azure:




You will have to pay more for data transfer if you are far away from your data source. If possible, store your data closer to the location of the data center where they are used.



Identify the best and shortest paths for data transfers across Azure regions and zones. This is one of the most cost-effective methods of transferring data.



Data should be compressed and deduplicated using incremental synchronization before being transferred. This will help reduce bandwidth or networking costs.




4. Not Knowing The Number Of Open Azure Cloud Accounts



Another sign that you may be spending too much on your Azure cloud is when you find yourself in a situation where you don't know what is going on with your account. This typically happens when you lack central control over your azure account, services, and resources. 



Organizations often have a number of users and accounts running diverse workloads, allocating resources to projects, and accessing a variety of services. These are the hotspots for your cost centers. If you’re not centrally managing all of these resources through a single account, then it can be hard for you to easily see where in your billings the costs are increasing or decreasing.



5. Lack Of Automation



If you don’t have any automation built into managing your Azure resources and accounts, then getting a grasp on your costs can become very difficult. For improved cost optimization, it's crucial to automate processes like workload scheduling, cost anomaly alerts, and termination of idle, outdated resources.



Benefits of Azure Cost Optimization



When it comes to cloud migration services and solutions, organizations can benefit in a variety of ways. What are these benefits?



Save Time and Money



One of the first benefits of Azure cost optimization is that it saves time and money. When you have an accurate understanding of how much you are spending on your cloud infrastructure, it becomes easier to make better decisions about how resources should be used (highly provisioned VMs). This helps you avoid wasting money on unnecessary expenses.



Gain Operational Efficiency



Another benefit of Azure Cost Optimization is that it provides visibility into how your IT environment is performing across all levels of provisioning and which activities are costing you money so that you can adjust costs accordingly. This way, you can make efficient use of your resources and improve productivity.



Gain Visibility



When you do Azure cost optimization, you can see how much money you're spending on various cloud services, like storage and computing. You can also see how much money is being spent on a particular application or service, which can be useful for budgeting purposes.



Allocate Budget Accurately



Finally, cost optimization can help you accurately allocate your budget across all of your cloud services, which helps ensure that you are maximizing the value of each dollar spent.

7 Proven Ways to Manage Azure Cloud Cost



Implementing and managing a cloud-based solution that optimizes costs is a challenging task. But not an impossible one. Here are some ways you can manage Azure cloud costs.











With Tools



1. Use Azure Cost Analysis Report



You can use the cost analysis tool to track and evaluate all aspects of Azure's costs and expenditures. For example, once workloads are running on Azure, you can use the Azure cost analysis tool to determine how much each workload will cost. You can also categorize, filter, and group resources depending on your findings.



The cost analysis tool can check:




Your organization's current monthly costs and expenses.



If any cost irregularities were detected.



Your Microsoft Azure billing against real service usage to ensure that the billing is correct.



How the cost of Azure should be allocated between departments, projects, or teams.




This tool also predicts future expenses based on current settings.



2. Utilize Azure Advisor



Azure Advisor is a cost optimization tool that helps you identify opportunities to reduce costs by measuring resource utilization. It provides insight into the costs associated with your workloads and provides recommendations on how to optimize them.



Azure Advisor works by analyzing resource usage for each virtual machine (VM) in your environment, identifying underutilized VMs, and recommending actions such as turning off unused VMs or resizing.



Manually



3. Consider Architecture Improvements



It's important to regularly and closely examine how your cloud applications and services are architected and used. By doing so, you can identify opportunities to right-size your instances, fine-tune your databases, modify the way you use storage, better configure your load balancers, or even tweak your applications.



Optimizing your cloud architecture will help you achieve these three goals:




Make cloud services more available, efficient, and user friendly



Get the most out of your cloud spend while balancing cost and performance



Document KPIs that justify your present cloud spending so that they may be used to support a higher cloud budget when growth requires.




4. Identify and Remove Zombie Infrastructure 



It is important that you are able to identify no longer-used infrastructure. For example, if you see CPU utilization below 5 percent in VMs within the past month, you're probably seeing a zombie. You may also find unattached Azure managed and unmanaged (VHDs/page blobs) disks. Generally, a volume can be terminated if it has been unattached for two weeks.



5. Proper Cloud Migration Planning



Cloud adoption is both an opportunity and a challenge for IT organizations. The more you can reduce the costs associated with cloud migration, the more likely your organization will be able to successfully migrate workloads to the cloud.



A proper cloud migration strategy is key to reducing these costs. Planning will help you identify all the requirements and business processes that need to be moved to the cloud. It also helps in identifying any hidden risks and potential issues that may come up during the migration process.







 VIEW CASE STUDY  







But to make the most of your adoption means getting in touch with migration and cloud experts like ModLogix who can help you understand what it takes to move from on-premise storage to the cloud without breaking the bank.



6. Use Storage Tiering



Storage plays a huge role in cloud overspending. Therefore, it is important to look at this area when optimizing azure costs. 



There are different storage tiers (hot, cool, and archive) in the Azure Blob storage model, and each one is priced per GB monthly. Using the right storage tier for the right kind of data will do a lot for your bills. For example, you can choose to store less frequently accessed data in the archive storage, which will mean lower costs per month. 



Moving from one Blob tier to another as your needs evolve can also result in significant long-term cost savings.



7. Multicloud Migration Approach



Multicloud migration can help you save on cloud costs. By moving data and workloads from one cloud service to another, you can take advantage of discounts and lower prices. You can also avoid vendor lock-in, making it difficult and expensive to switch cloud providers.



So if you're looking to save on cloud costs, multicloud migration is a great option. These days, multicloud cuts across public, private, and hybrid clouds, or a combination of all three to satisfy specific business requirements.

Closer Look at AWS Cost Management vs Azure



AWS and Azure are two of the most popular cloud computing platforms on the market. Both offer cost management features that can help businesses save money on their cloud computing costs. However, there are some key differences between the two platforms that you should be aware of before making a decision.





On the one hand, AWS provides at least 7 reporting and cost-optimization tools that show users how to reduce AWS costs. These are AWS Budgets, AWS CloudTrail, AWS Cost Explorer, AWS Cost, and Usage Report, AWS Trusted Advisor, Amazon CloudWatch, and Amazon S3 Analytics.





Azure, on the other hand, comes with only a number of built-in tools for cost optimization. Azure cost management and billing for budgeting, the Azure pricing calculator for estimating and forecasting, and Azure advisor, which provides recommendations on how to optimize your cloud environment's costs.





If you compare the number of tools available to lower costs between AWS and Azure, AWS would win clearly. 



It is worth noting, however, that the Azure Cost Management tool does multiple tasks, whereas many of the Amazon Web Services tools duplicate each other.



Apart from the versatility of Azure Cost Management, this tool also provides a dashboard to manage costs for both AWS and Azure cloud users. A feature that is not available in AWS.



Consider Azure Cost Management Best Practices from ModLogix



Cost management is a great way to keep track of your spending and optimize your resources. But it can be tricky to know where to start.

### Compatibility of ASP.NET Webforms and ASP.NET MVC

As the pool of technology supporting Webforms continues to shrink, you want to know if it’s a good idea to modernize your application by integrating ASP.NET Webforms and ASP.NET MVC. Judging from our vast experience with clients making the same move, it is worth it.



Done right, you can avoid the high cost of maintaining legacy systems. That’s better performance on crucial business tasks, and better profitability. 



This article explains the compatibility of ASP.NET Webforms and MVC, how developers combine them, as well as the risks and rewards. 



Explaining ASP.NET Webforms and ASP.NET MVC 



Although ASP.NET Webforms is still available in Visual Studio, the framework is no longer the most innovative. As most interactive designs are centred around JavaScript, Webforms isn’t suitable for all applications e.g. in the cloud. This is because the load speed is too slow for modern expectations. 



JavaScript does work well with server control HTML generation which is not the outdated Webform’s strong suit. But it’s a breeze for ASP.NET MVC architecture. ASP.NET MVC is Microsoft’s more robust upgrade to the legacy ASP.NET Webforms that solves Webforms’ JavaScript development issues. It does not use view state or server-based forms making it easier for developers to work faster and more securely.



However, it is not necessary to completely rewrite your legacy system. It is possible to leverage ASP.NET MVC for your existing ASP.NET Webforms apps as you modernize your legacy application. It is one of the reliable legacy system modernization approaches we have helped clients with. It’s a solution that addresses the critical failures, security problems, process efficiency, and costs of running Webforms. 











ASP.NET MVC is bound to the same runtime environment as ASP.NET and has tight dependencies on IIS and the system.web assembly. As ASP.NET MVC requests are routed through the same exact pipeline, the two are compatible. In fact, intrinsic objects such as Cache, Session, and User are the same, and plain ASPX pages work without any changes to the configuration as the system can match MVC and Webforms.



Using Mixing ASP.NET Webforms and ASP.NET MVC in One Application



Let's look into the viability of this approach to answer your questions on legacy application modernization. If your aim is to add new features using Ajax and libraries such as jQuery, jQuery UI, Bootstrap, Knockout.JS, or Breeze, consider merging the MVC project with Webforms. Leveraging them together in your legacy software allows you to take advantage of ASP.NET MVC’s support for HTML rendering and more. 



You also have to be aware of common add Webforms to MVC project problems in legacy system integration. The major disadvantage of mixing Webforms and MVC has two separate areas within the runtime might slow down performance as debugging is done for both sets of requests. However, the difference is negligible given that the extra load is limited to system.web.mvc. Partnering with a software modernization company will help you negotiate this modernization approach successfully.



When Can I Mix ASP.NET Webforms and ASP.NET MVC?



So when does mixing MVC and Webforms in one project work? Here are different scenarios most of our clients encounter.



Case 1 Complete move to ASP.NET MVC



If you are planning completely migrate WebForms to MVC, it might turn into a hybrid Webforms MVC app during the move. Gradually all modules will be rewritten for MVC, but in the meantime, you can mix the two so as to keep your application running.















Case 2 Adding new features in JavaScript



Thinking of adding new JavaScript-intensive features in MVC without touching the rest of your code? Then mixing Webforms and MVC is a viable option. You can simply add new features using MVC concepts without having to rewrite the whole application.



When not to Mix ASP.NET Webforms and ASP.NET MVC



Modifying your application to take advantage of popular JavaScript programming doesn’t always have to mean rewriting your code. Neither does it mean you have to mix Webforms and MVC. Modernizing your existing Webforms project to be more interactive and rich typically involves leveraging jQuery and jQuery UI plugins. You can achieve this by adding a Web API to your Webforms application. After all, there is nothing wrong with using Webforms for your applications.



Using alternative solutions 



If you decide not to go with this hybrid approach, you can choose to: 



Rewrite using ASP.NET MVC



If you are compelled to ditch Webforms completely for ASP.NET MVC, it’s going to be time intensive. As you are dealing with an existing project, it is realistic to assume you will be rewriting everything one module at a time.



The process itself involves writing controllers, Razor views, and routes as well as preparing CSS and script bundles. In addition to familiarising your team with elements like the Twitter Bootstrap framework and libraries such as jQuery and Knockout, you will also need AngularJS expertise.



Insert Web API



Opting to integrate a Web API layer into a Webforms application is less strenuous compared to rewriting your entire project. Web API is somehow similar to ASP.NET MVC in how it works. It makes HTTP endpoints easily callable to JavaScript frameworks. However, unlike MVC, it is completely separated from the ASP.NET runtime.



Explaining how to insert APIs to consolidate your legacy systems under one roof. How to Effectively Conduct a Legacy System Integration 



The Web API solution doesn’t require much work to produce more interactive applications. You simply plug in the Web API runtime, configure routing choose the URLs you want to support, and start writing your controller classes in the App_Code folder. Here is a sample:



public class NewsController : ApiController



[HttpGet]



    public IEnumerable<string> All()



    {



       // Your logic and return data



    }



How to Blend MVC Modules and ASP.NET Webforms



To utilize Webforms and MVC in the same project, you can add MVC references to the existing application. But how? 



You should know that the ASP.NET MVC framework was developed on top of ASP.NET. Thus, technically, the only difference is that while ASP.NET is found only in System.Web; ASP.NET MVC lives in System.Web,System.Web.Routing, System.Web.Abstractions, and System.Web.Mvc. When you add these assemblies as a reference in an ASP.NET application, you have a perfect footing for merging the two technologies.



Put simply, since ASP.NET MVC is built on top of ASP.NET, data can be easily shared between the two technologies. For example, data can be transferred through the Session state because of the availability of the Session state object in both technologies.



The two frameworks ASP.NET Web Forms and ASP.NET MVC can easily share data as they also share the same runtime environment. Requests are routed through the same pipeline. All that is needed for the incoming request is to match the URL specifications supported by the MVC handler.



Put more simply



Follow the following steps. Add a reference to the three assemblies to your ASP.NET application:



System.Web.RoutingSystem.Web.AbstractionsSystem.Web.Mvc



Subsequently, create the ASP.NET MVC folder. Since this framework relies on some conventions (e.g. controllers living in Controllers), adhere to the conventions. Add all the necessary folders, Controllers, Views, and Views | Shared to your existing ASP.NET application.



After that, you have to update the web.config file using a code that registers a default ASP.NET MVC route, which will map any URL of the form /Controller/Action/Id into a controller instance and action method to avoid MVC Webforms hybrid problems. 



Complete the process by introducing a new controller in the Controllers folder to add Webforms to the MVC project. You can also add Webforms to MVC projects as they are compatible both ways.

However, we couldn't achieve these results without our clients. So, we want to take a moment to remember the most notorious projects for software transformation we did last season.



Migration from AngularJS to Angular 11



Since AngularJS end-of-life became a buzzword in 2021, almost every company thought over AngularJS to Angular migration. Our team was in charge of AngularJS upgrade for an enterprise platform that experienced low performance, inflexible architecture, and maintenance issues.



We upgraded frontend and backend parts, rewriting software parts piece by piece, selecting the new Angular components, redesigning the platform, and migrating all the necessary data. 















By the end of the project, the client received the quality product, complete documentation, and streamlined software structure. Our team refactored 65K lines of AngularJS source code with thousands of functions and classes!      



Moving WinForms to .NET Core 



Our client is a large enterprise offering financial and insurance services in the healthcare industry. Their 20-year-old WinForms-based platform became inefficient for day-to-day operations. In the meantime, the company went through the merger and acquisition (M&A) process, and its software was incompatible with modern systems.



ModLogix experts dealt with the disparity of technologies, integration, and functionality issues. The only choice was to rewrite the whole system, including incremental MS SQL database upgrade, desktop system redesign, and web and desktop versions maintenance simultaneously. 



As a result, our clients and end-users took a boon from a brand-new web platform. This upgrade improved the overall performance and helped to accomplish the M&A process successfully.















Final Thoughts



We wouldn't be celebrating this moment if it weren't for our clients' warm support and trust. ModLogix is eternally grateful to be surrounded by wonderful people who believe in our capabilities. Their confidence in our team gives us extra motivation to work hard.



Thank you so much to everyone! It's a tremendous pleasure to serve as your trusted partner. We couldn't tell you enough how honored we are to receive your stamp of approval. Cheers to more opportunities for all of us ahead!

### Angular 14 New Features and Benefits for Business and Developers

Angular 14, the latest version of Google’s TypeScript-based web application framework, is now available. It comes with new and improved features that could change the way Angular components are written and more. So what’s new in Angular version 14? Here is an overview of the framework’s latest major update and why you should be moving to version 14. 



When is Angular 14 Coming Out?



For those who were wondering when Angular 14 will be released, the wait is finally over! According to Google’s plans, the stable version was in the works, with the Angular 14 release date set for June 2022. The new version became available on 02 June 2022, succeeding Angular 13, which was released in November 2021.



Comparing Angular 13 vs 14: Improved Efficiency and Speed



Angular 14 takes over from Angular 13 as the framework’s latest major update. Developers can look forward to exciting changes to quite a number of processes in the new version. But how does it compare to v13 in terms of speed and efficiency?















Angular 14’s pre-planned improvements, including standalone components, support for Typescript 4.7 (latest version), optional injectors in embedded view, and more, significantly change how Angular applications are written. All these are features Angular 13 was missing. It makes it easier to develop Angular applications and also makes v14 more efficient and faster as compared to the previous version.



New Angular 14 Features



Let's look at Angular 14 features in detail. Here’s what's in it for you.















Standalone components



Angular 14 standalone components allow more flexibility in component module association as NgModules are now optional. Since they are still an available option, you don't have to worry about v14’s compatibility with the existing Angular-based apps and libraries ecosystem.



Experts predict AngularJS future. How's risky staying with this outdated technology? Experts Answer 10 Common Questions on How to Migrate from AngularJS 



Strictly Typed Forms 



Typed forms have been introduced in Angular 14, improving how the framework works with forms. The FormControl will now accept a generic type that tells a certain value it carries. This solves the issue of implementing strict typing for the Angular Reactive Forms Package on GitHub. This change will not affect the relationship with existing template-based forms and has been future-proofed with the Auto migration added in v14.



Optional Injectors in embedded views



Optional injectors can now be introduced in embedded views in Angular 14 using via ViewContainerRef.createEmbeddedView and TemplateRef.createEmbeddedView.  



Angular CLI Auto-Completion 



Angular 14 comes with a much-needed CLI auto-completion feature. You can look forward to real-time auto-completion of commands in the terminal, making it easy to find your way around. For new Angular and Typescript developers who have been struggling with the steep learning curve for the framework, this makes things all the more easier—no more looking up commands online!



Advanced template diagnostics



Developers can look forward to enhanced template diagnostics for compiler matching to typescript code. The diagnostics tests also work with the private compiler introduced in Angular 14. The warnings from the compilers will help developers save time and avoid mistakes in their code. In previous versions the compiler would just stop executing if it encountered a problem and did not inform you of what the issue was.



Streamlined Page Title Accessibility



Adding a title to your page is now simpler without the need for additional imports as you develop your application. This makes it easier for developers to adapt to the changes in version 13 that introduced the new Route.title in the Angular router. 



New Component Dev Kit Primitives



You can expect new CDK primitives including the Dialog and the CDK Menu in Angular 14. This will account for better accessibility for custom components.



Online Angular DevTools



The new online mode for Angular DevTools in the revamped debugging extension is a welcome improvement. This feature is available as Mozilla Add-ons for Firefox users.



Built-in enhancements



The recently released Angular 14 supports TypeScript 4.7, also targeting ES2020 by default. In addition, the CLI can deploy small code without devaluing it. You can also now link to protected component members directly from templates giving you more control over the public API surface of the reusable components. 



Extended developer diagnostics



Angular 14’s extendable framework provides you with advanced insights on your templates, with suggestions on how to boost performance.

How to Upgrade to Angular 14?



Migrating to Angular 14 gets you access to these latest upgrades on the framework. Let’s jump right into how to get it done!



Migration from Angular 12/13 to Angular 14



If you are currently using previous versions of the framework, namely Angular v12 or v13, migrating to v14 is a straightforward path. To install your required version of Angular CLI globally, start by running the following on the command-line interface:



npm install --global @angular/cli@next 



From there, open a new command-line interface and run the following:



npm install --global @angular/cli@next 



This command will prompt the installation of Angular 14 on your development machine.



Upgrading from Angular 13 to 14? Then visit the official website for a swift update. There aren't any changes necessary when updating from Angular 13; however, make sure you are using Node 14.15.0 or later as advised by the Angular team. From the command-line interface, run the command:



ng update @angular/core@14 @angular/cli@14 



This will update your current version of Angular to v14. Ensuring your applications are ready for migration can be complex, but our team here at ModLogix has experience in Angular migrations and can help smoothen the process.

Migrating from AngularJS to Angular 14



If you are moving from Angular JS, there are more steps you have to take to avoid breaking changes that come with the update. As AngularJS is the name for all 1.x versions of Angular, the transition has a different supported AngularJS migration path. The best way is to do incremental upgrades by running the AngularJS and Angular 14 frameworks side by side in the same application and porting AngularJS components to Angular one by one.



The upgrade module in Angular makes incremental upgrading seamless. It also helps to align AngularJS applications with Angular in preparation for the migration. To do this you can make the code more decoupled, more maintainable, and better aligned with the latest development tools. With this approach, migrating complex applications of any size becomes achievable without disrupting other functions.



However, a successful incremental upgrade will also require you to avoid common migration mistakes. There are rules you can follow to simplify your migration. As you will be using the Angular upgrade/static module, there should be one component per file, and different parts of the application should reside in different directories and NgModules. It's easier to get an AngularJS development team on your side to ensure every application is migration ready.







  VIEW CASE STUDY   







Takeaway



With the new transformative features in Angular 14, adopting the updated framework or your application development will help boost efficiency. Developers will find the changes to the Angular framework quite helpful in simplifying some complex operations like working with typed forms. The introduction of standalone components and support for the latest version of Typescript also increases the possibilities for Angular apps. There are no better signs to tell you it’s time your business migrated to Angular 14.

### 3 Legacy Software Modernization Case Studies and 12 Lessons We’ve Learned

According to a recent survey, businesses that fail to modernize their software systems run the risk of losing up to $1.8 trillion in productivity.



Although software modernization works, it can be complex and costly. That’s why it helps to learn from some of the successful legacy system modernization case studies. 



This article discusses 3 legacy system modernization success stories of our valuable clients and the lessons learned.



Case Study #1 Upgrading AngularJS to Angular 11 for an Enterprise-wide Web Platform



A premium provider of information technology and financial services in the healthcare industry experienced bottlenecks with their multiple module system built on AngularJS. They sought to migrate from AngularJS to Angular 11 to overcome these challenges.



Major challenges encountered during migration and our solutions




Dealing with complex functionality and architecture: Since the architectural patterns in AngularJS and Angular are completely different, our team aligned the business logic of the solution with the target system.









Selecting proper substitutes for legacy AngularJS tools: We carefully chose libraries to facilitate further maintenance on the new Angular 11 system.









Efficient management of user resistance to the new designs: We devised a plan to boost user acceptance towards the new look of the application.









Data transfer was the second-hardest task: This is one of the many disadvantages of legacy systems – moving data to better infrastructure. Our team took an incremental approach to migrate data that eliminated disruptions and operational interruptions.




The results



The client received a quality product, complete documentation, and a streamlined software structure. They gained a higher ROI with improved performance, and credits to the new on-time system. Maintenance costs were reduced as bugs and errors can now be resolved much faster and with less effort.















The project, which is still ongoing, taught us the following lessons



Lesson 1 Frameworks with the same roots can be utterly different; thus, they must be approached differently



AngularJS and Angular 11 are completely different, so the frameworks require different approaches, and the upgrade wizards won’t help. Approximately half of your application’s codebase must be rewritten from scratch to ensure a smooth transition.



Lesson 2 Redesign the app in parallel if users and business context require it



The new solution's frontend might require a few UX changes by a developer during the migration.



How to do a legacy system redesign the right way? Read here. Risks and Approaches of Legacy Application UI and UX Modernization 



Lesson 3 Don’t be afraid to rewrite the app’s parts or the whole app piece by piece



If rewriting is carefully planned and done right, the new solution will fit your budget, meet deadlines, and maximize the ROI.



Lesson 4 Consultation with a professional software modernization company ensures successful migration



Switching from AngularJS to Angular is complicated, so do it with an expert legacy systems modernization vendor. A proper consultation will save you money and reduce the development time.



Read the full version of the case study on AngularJS.



Case Study #2: Migrating .NET Framework 4.7 Backend of the Large-scale Enterprise System to .NET Core 3.2



For this legacy software modernization case study, we helped our client, a key player in the US healthcare market, achieve a successful .NET Framework to .NET Core migration. 



Major challenges encountered during migration and our solutions




Recreating the functionality of the target system: During the migration, our team rewrote some parts to save the initial system’s structure. 









Selecting proper substitutes for the missing .NET Framework libraries: Most third-party controls and libraries of the .NET can’t be ported to .NET Core. So, we had to manually choose the needed libraries and controls.









Implementing new features on the go: The business needs kept changing throughout modernization, forcing our team to work on the new functionalities concurrently.




The results 



This 6 months project allowed us to provide an improved application to our clients, with more opportunities for users. First, in contrast to .NET Framework limitations, .NET Core lets the system run smoothly on Mac, Linux, and Windows. With the new .NET standard libraries, their dev team can now implement crucial features much faster in different environments at once.















Lessons we learned from this migration



Lesson 5 Refactor, refactor, and refactor again



Refactor code until you can't. By legacy code refactoring, we enhanced the structure, design and implementation of the program. This, in turn, minimizes complexities and improves code readability and maintainability.



Lesson 6 Plan the migration in advance



Start making plans to upgrade your application and invest in solid documentation because the lack of it becomes the biggest obstacle to modernizing outdated applications.



Creating the app modernization roadmap can put your project on the rails. Creation of Effective App Modernization Roadmap: Everything You Need to Know 



Lesson 7 Thoroughly choose the proper substitutes for the existing app’s libraries and components



Even straightforward migration projects might fail. You need to replace existing app libraries with compatible ones; you don't choose randomly. Select elements according to the system’s functionality and the initial structure.



Lesson 8 Avoid possible pitfalls during the migration from the very beginning



There are many pitfalls for software migration projects, and the one thing you can do here is to follow industry best practices. Starting with frequent system audits to be in the loop of any issues, learning about tech updates (and we know the best place to look for them - ModLogix blog), and working with a trustworthy legacy software modernization company.

Case Study #3 Cloud Migration from ASP.NET Webforms to Microsoft Azure 



Our client is a scalable clinical trials database registry for this case study.



Major challenges encountered during migration and our solutions




System environment parameters: Moving the system to the cloud could cause malfunction and security concerns. To solve this issue, our team built a development environment in the cloud and rewrote some app parts to make them compatible. 









Database compatibility: The MS SQL database used in the current system needed upgrades and fixes because it wasn't Azure SQL compliant. We solved these challenges by building an ASP.NET app for inserting into the Azure SQL database.









Unsupported parts: Azure Firewall was incompatible with the current solution - flagging several harmless requests as potential threats that could stop the whole system's work. To mitigate this, our team replaced the Azure Firewall with Cloudflare Firewall, which allowed specific requests.




The results



With this 4 months project, we delivered a modern application that offered 200 times faster report building, 99,99% guaranteed business continuity, and 297 code issues fixed. Our expertise in mobile development allowed us to build a biometric authentication app.















The project allowed us to learn the following lessons



Lesson 9 Calculate the cost of cloud migration beforehand 



In order to meet the budget, you need to be aware of all the upcoming costs - pre-migration, cloud, migration, as well as post-migration costs. List everything to avoid unpleasant surprises. 



What should you pay attention to when estimating the cloud migration. How to Estimate the Cost of Cloud Migration 



Lesson 10 Understand your workloads before selecting a cloud model



The amount of workload that your business deals with affects the cloud model that you should opt for. Consider elements like request size, web page load time, and time zones.



Lesson 11 Pay attention to the solution architecture in the cloud



Work with Data architects to implement several best practices when planning, building and maximizing the benefits of a cloud data architecture. Adopt metrics to assess how cloud services can minimize the cycle time of data analytics applications.



Lesson 12 Adopt a comprehensive approach to development 



It is important to choose the most suitable method among legacy software modernization approaches to meet all of your project needs.

### The Ultimate Guide on Transition From One Electronic Health Records Software (EHR) to Another

As of 2021, over 96% of non-federal acute care hospitals and other health centers have adopted an Electronic Health Records software system (EHR).











However, recent surveys have revealed worrisome levels of dissatisfaction with EHR systems. As a result, many healthcare facilities are changing EHR systems to newer and better systems on the market. 



It’s no secret that the transition to newer and better EHR systems to support the ever-changing patient and hospital needs is inevitable. However, healthcare isn’t like any other business where the transition from one Electronic Health Record to another takes place overnight.



This article provides you with the ultimate step-by-step guide for a transition from one EHR to another.



Why Would Hospitals Consider Moving from One EHR to Another



Old EHR systems can be considered legacy systems in software engineering, so the transition to new infrastructure is always going to happen. An American Academy of Family Physicians (AAFP) survey provides the following reasons why hospitals consider moving from one EHR to another:




45% of hospitals sought to achieve more meaningful use from their EHRs.









20% of these health organizations consider transitions to new EHR in search of more stable vendors.









35% of the respondents consider a transition in order to save money. 
















The Benefits of EHR Hospital Transition



EHR to EHR hospital transition is difficult, expensive, and resource-consuming, but the operational and financial gains are worth it. 59% of the health institutions responding to the AAFP survey strongly agreed that their new EHR systems have new functionalities and are more useful.



Other important benefits that come with the transition to a new EHR include:




New EHR systems provide better support and training through their vendors.









More recent EHR systems are easier to use and are much quicker, and more efficient.









New EHRs come with fewer technical problems and lesser cost of operation.









Maintaining, updating, and adding new features to recent EHRs is cheaper and easier because they’re built with recent, more advanced technology.








New Opportunities with New EHRs



Integration with other applications



There are multiple applications on mobile and PC that can add limitless functionality to EHR systems. From efficient payment portals to patient engagement interfaces, the integration opportunities are endless. Most of these EHR-integrated applications are built on newer technology to work with newer infrastructure.



Opportunities with mobile medicine



Mobile devices are shaping health in multiple ways. It’s impossible to ignore a technology that virtually every patient uses on a daily basis. Updated EHR systems will allow your organization to integrate and offer mobile medicine services to patients through an app-enabled patient portal.



Access to cutting-edge technology



Artificial Intelligence, expert systems, the Internet of Things (IoT), and cloud-based technology are some of the leading technologies healthcare facilities can add to their existing EHR systems. Such technologies make it easier to process and store data and minimize errors that could arise from less advanced systems.



Another opportunity with new EHRs is the possibility of integrating legacy systems, which transport data from on-premises legacy systems (an older EHR) to advancing new systems such as the cloud.



EHR to EHR Transitions: Step by Step Migration



Choosing EHR systems will have a long impact on your hospital organization. To make the most of your new EHR system, a smooth migration process is necessary to cut down the EHR switch cost and eliminate productivity issues during the switch.















1. Choose your new EHR system and EHR vendor wisely



Your EHR provider is not only responsible for providing you with an EHR system customized to your precise need, but they’re also responsible for a smooth transition to a new system. However, it’s your responsibility as the healthcare organization to find the right vendor/provider to handle the transition.



You should choose an EHR vendor or provider who:




Has experience and expertise dealing with antiquated (legacy) systems, because chances are, your current EHR will become outdated with time. Few developers are capable of working efficiently with legacy code, this is one of the many disadvantages of legacy systems, including old EHRs.









Offers a well-thought-out EHR to EHR transition plan. Some vendors make these transitions much easier by putting a streamlined transition process in place and offering the necessary expertise in the healthcare industry.









Guarantees on-time support and maintenance even after the migration process.




2. Learn about the data transfer process



Data transfer is at the heart of the transition. It is the biggest challenge you may face when transitioning from one EHR software system to another. As such, it is important to learn all you can about data migration from one EHR to another to understand your role in the process.



Start by reading the technical documentation and speak to your vendor. Find out where you come in and what you can do to ease the process. For instance, you may identify what data needs to be transferred or archived, and match data records or workflows in the current EHR to those in the incoming system.



The more you know about how this data transfer works, the better you’ll collaborate with your vendor in the healthcare data migration process.



3. Analyze your current EHR and choose what data to migrate



Not all recorded data in your current EHR will come with you. Workflows change, processes evolve, and so, not all data records in the current system are relevant for the future EHR system. 



Set up a team of clinicians, administrators, and managers to analyze the existing paper records and select what needs to be migrated. At this point, don’t forget to define the new workflows for your organization after the EHR to EHR switch - the old workflows might not be best suited for the incoming EHR, especially if it’s a cloud solution.



4. Help your vendor execute the migration





The vendor needs your assistance and supervision with the data transfer. You may need to hire more IT personnel to write migration code, provide bug fixes and patches, run tests, and deal with other technical activity.



The input from expert EHR consultants is also essential for smooth migration,





and data abstraction as these professionals will provide insights into how old/current records will be recorded and operated upon in the new system. How current operations/processes in the existing EHR should be implemented in the new EHR without breaking or changing the operations in your institution.





5. Plan for training in advance



A new system brings in a new interface, new functionality, new processes, new constraints, new limitations, and new opportunities. As such, your hospital staff (from clinical staff to IT personnel) must undergo training on how to make the most of the new EHR system.



If new workflows and processes were developed during migration, these must be taught to hospital staff interacting with the EHR every day. Plan the training sessions beforehand and implement the training before the transition is complete to avoid a drop in the productivity of your staff.



6. Test your new system before going live



Training is part of the migration process because after developer tests are complete, it’s up to you and your staff to evaluate the newly implemented EHR system. Before you go fully live with your system, perform as many tests as you can to find bugs and challenges with the new system’s utility. Get to know your new system inside out at the very least.



How to test a legacy codebase without breaking anything? Learn here. Testing Legacy Codebase: What is, Common Problems and Best Practices 



In case of any troubles, inform your IT department and notify your vendor as soon as you can.



Common Challenges When Migrating from One EHR to Another



1. Data transfer



There’s no challenge bigger than data transfer and configuration. It is not as easy as copy-paste. Certain migration algorithms need to be implemented to move the records from the current EHR to the incoming EHR.



2. High costs of switching



The costs of hiring new IT personnel and expert consultants (if you go this way) to oversee the data transfer process are high. Purchasing the new, advanced EHR you’re implementing is also not cheap.



3. Maintain compliance



Because patient information and other types of health records are hyper-sensitive, even the transition process must be implemented in compliance with government health regulations such as HIPAA and GDPR. Failure to do so may bring in legal issues from the governing federal or state body.



4. Migration can take time and affect productivity



The EHR transition planning, data transfer, training, and testing processes are also lengthy, and this plays on the overall length of the entire transition process. Such a lengthy transition process coupled with a possible suspension of other digital operations may affect the overall productivity, and not in a good way.



However, this might not be a cause for concern as the time taken throughout the process entirely depends on the complexity of the old software, new processes, and the changes your healthcare unit seeks to introduce in the new system. So, the transition process might be either difficult or simple.



Tips and Recommendations for an Efficient Transition from One EHR to Another



HIPAA/GDPR compliance



Patient information is sensitive. Ensure that your transition process follows all the regulatory compliance standards for healthcare. Your vendor/provider and your new Hospital Charting systems (EHR) must also be compliant with these regulations.



Sufficient training = Smooth transition



Plan and implement staff training on the operation of the new EHR system even before the switch is complete. Trained staff members are able to adapt to the new system without affecting their productivity.



Effective communication 



Timely and effective communication between your organization, your personnel, the hired consultants, and your vendor/provider will always be essential for a smooth migration process.



Get your timing right 



A hospital is always a busy place, but some periods are considered “slow”, compared to others. These “slow” periods with low activity are the perfect times to implement a transition project to reduce a loss in productivity and quality of healthcare provision. Take into account the time and resources you need to spend for a smooth and complete migration. That way, you’ll avoid the unpleasant surprise of unmet needs and lost budgets.

### Testing Legacy Codebase: What is, Common Problems and Best Practices

“Code without tests is bad code. It doesn't matter how well written it is; it doesn't matter how pretty or object-oriented or well-encapsulated it is. With tests, we can change the behavior of our code quickly and verifiably. Without them, we really don't know if our code is getting better or worse.”
 Michael C. Feathers, an author of the book “Working Effectively with Legacy Code”. 



Testing legacy code is somewhat of a punishment for most developers. How do you even begin creating tests for legacy code in a messy codebase?



In this article, we’ll help you understand how to approach legacy code testing. You’ll discover some of the most common problems you’ll come across while testing and refactoring legacy codebases and techniques to help you solve them. More importantly, we’ll share our best practices for automated testing of legacy codebases and reveal the issues you may face with legacy code testing. So, let’s begin!



Why Testing Legacy Code is Different from Normal One



In terms of software QA testing, legacy code is qualified as code that doesn’t have a suite of automated tests. It may initially seem like ‘untestable code’ - difficult to modify because of the high risks of emerging vulnerabilities and critical bugs.



When writing tests for untested code, you often have three possibilities: automated testing, manual testing, and unit testing. For manual tests, the test cases are executed manually without using any automated tools. With unit testing, you’ll be writing tests for the smallest units of your code, this approach is lengthy and not the most suited for legacy code.



Automated testing of legacy code requires you to use particular software tools to automate the process of reviewing and validating code. The goal is to make legacy code testable, maintainable, and scalable - with minimal effort.



Why is legacy code testing different from other testing systems we’re currently building?




Legacy codebases have very low test coverages. This means the chances of breaking up are very high.









Hard-wired dependencies: With legacy code, you often have loads of classes, methods, and control structures that were not written to be tested and are considered one of the furriest disadvantages of legacy systems. It becomes next to impossible to isolate dependencies.









Poor or no code modularization. So it’s hard to mock out parts.









Code is very bulky; thus, unit testing legacy code is a bad idea or won’t work.









You might be required to change the production code in order to add the tests. Doing this adds risk because you may end up introducing a bug when manipulating code manually.








Regardless of the challenges, testing legacy applications is very possible.



7 Best Practices for Legacy Code Testing 



When developers are asked to write tests for some legacy codebase, they will be writing tests as they would with regular code, but with a few key changes. Here are some of the best practices to be adopted when writing tests on legacy code. Also covered are techniques used when approaching such code.



1. Practices developers should give up from the jumpstart




Desire for 100% test coverage. You’re not testing normal code, so developers cannot focus on getting 100% coverage. It’s almost impossible to reach! Good or medium coverage is better than nothing!









Legacy code unit testing: Legacy codebases are generally huge and complex. Instead of trying hard to test a particular loop of a certain method of a certain class, focus on “big” tests like integration and functionality tests.









Frequent context switches: Make all your tests pass without changing the model code as you would normally do.
















2. Get the build and existing tests working



Get your system build and existing tests working, this is essential. To do this, you must first evaluate the current state of your codebase.




What tests already exist?



What code is covered by these tests and how much coverage does that provide?



When do these tests run?






Make sure all existing tests, if any, are up and fully working first. Then, write your first tiny test. Doesn’t matter whether it’s on a getter or a two-string method, write that first test. This is in order to get the build system set up. But make sure not to eliminate failing tests until you understand why they’re changing.





Think of what to test next. Maybe the main method. It could be a little messy to do so, but it’s sometimes a good place to start if you can. Testing the main method may bring up threads, GUI, etc.





Here’s a sample test on the main method for a healthcare management system - testing the code's functionality using JUnit.



Whatever method or class is convenient, write your first tests. The simpler, the better. The goal is to begin the transformation by raising the coverage one step at a time.



3. Go big



With legacy code, it’s better to see the bigger picture and look at the tests from a wider perspective. You must write tests for legacy code on a larger scale. Avoid tiny, unit tests: class -> method -> loop -> if statements… You should write broad tests for particular tasks, such as GUI tests or integration tests to verify large processes.



More importantly, prioritize test cases. In general, test case prioritization is the process of determining which tests are most important to execute first. It is usually performed in order to improve the efficiency or effectiveness of testing. The goal is to maximize the probability of detecting a defect or other failure condition as early as possible.



The first thing to do is to identify the most important metrics for prioritization. And here is a list of some of them:




How critical is the feature to be tested? If a feature is key and does not work, give it a higher priority.



Test case execution time (the less, the better).



Test case code coverage (the more, the better)



Number of test cases passed (the more, the better)



Risk associated with the feature or bug. Risks can impact your ability to deliver new features or fix bugs quickly. Prioritize tasks based on the impact they have on your business.
















More examples of big picture tests are; tests for driving UI or testing APIs.



4. Implement testing within CI/CD pipeline



CI/CD pipelines ensure that new changes don’t break existing functionality and that automated tests are run on every check-in to the code repository. Continuous Integration (CI) helps organizations deliver new features faster. 



The best way to test legacy code is to automate tests and run them in a Continuous Integration (CI) environment. Here's how to do it:



1. Write a set of tests (test suite) for each class in your legacy application, using whatever language or tooling you prefer. If you're using JUnit or another unit testing framework, this step should be easy enough. But if you're using something more exotic, then writing those tests might be a bit trickier than just writing regular JUnit tests.



2. Make sure all of these tests pass before moving on to the next step — don't skip this step! After all, if at least one of these tests fails, then it means that some aspect of your code needs fixing before proceeding with further steps in the process. The goal is to create a test suite that ensures.



Tools: TeamCity, Jenkins.

5. Prepare the set of smoke tests



What if there was a way to figure out what parts of your legacy code are worth testing?





That's where smoke tests come in. Smoke tests are basically like a snapshot of your application at a particular state. They let you see what needs testing and what doesn't. They don't test every possible scenario, just enough to get a general idea of how things work together.





A good smoke test suite is a must for any legacy code base. It's a good practice to create such a set when you start working on a legacy project. You’ll use this to ensure that your changes don't break anything in the system.





To prepare the set of smoke tests for your legacy code base, follow these steps:



1) Identify the main areas of application functionality.



For example, if your application is a healthcare management system, then there are certainly several areas of functionality such as patient registration, billing, doctor scheduling, etc. Identify each area separately — because they may have different types of tests required (for example, integration tests).



2) Create unit tests for all public methods in each area identified above (this should be done before doing anything else).



3) Create integration tests for all external dependencies (such as external services, databases, etc.).



Legacy software integration is another headache for many companies. Learn how to deal with it. How to Effectively Conduct a Legacy System Integration 



Smoke tests aren't meant for long-term use - they're meant to give you an idea of where things are going wrong before writing more extensive tests or even working on the feature itself.



6. Plan regression tests



The main problem with legacy code is that there may be no regression test suite. Regression tests are essential because they make sure that any changes to our codebase do not lead to code corruption or unexpected behavior changes.



There are two different types of regression tests:



Functional Regression Tests – These are the most common type of regression test and are also known as black-box or behavioral tests. Functional regression tests focus on testing an application or website against a set of functional requirements. A functional regression test is usually automated but can be manual if necessary.



If you have a large number of functional requirements, it’s not practical to write a test for every single one of them. Selecting which ones to automate will help you prioritize your effort and ensure that you cover the most important parts of the system first.



Acceptance Regression Tests – Acceptance testing is done by users and stakeholders to assess if their experience with the software meets their expectations and is working as expected.



Regression testing can also be performed manually, but automated tools are typically used because they are faster, more reliable, and easier to maintain over time than manual testing methods such as Excel spreadsheets or spreadsheets.



7. Code coverage measurements



With legacy code, 10% code coverage is way better than 1% coverage. So another great practice is to run code coverage measurements to generate coverage reports that give you a clearer idea of what is yet to be done or what you’ve missed.



Tools: Emma, Cobertura, etc.



8. Invest in technical documentation



What do developers dislike more than legacy code? Incomplete or missing documentation! That's why your team must always document all the changes that have been made to the system.





Technical documentation can be an external document that explains the architecture of the system, or it can be embedded into your test code. The goal is to help future developers understand how to work with your code and reduce their learning curve.





Such documentation will help your developers understand how the application works and how the system interacts with other components, such as databases or servers.









Technical documentation of legacy systems is good practice in software modernization as a whole, but most companies write it for these purposes:




When there’s a need to rewrite or an existing feature has been modified.



While adding new features and improving existing ones;



When you want to refactor your codebase;




More importantly, your documentation will help keep track of what has been tested and what hasn't been yet in case there are gaps in coverage. Yet the greatest pain point that documentations solve is how they reduce time and effort for maintenance and the development of new functionality.







Testing Legacy Code during Software Migration



Automated testing is a good suit for software migration projects. There are various techniques and approaches to move your applications to modern environments, and consequently, they require a unique testing approach (roadmap). If you choose rewriting or re-architecting that involves a lot of changes to the original system, you’ll get a real chance to restructure the software according to the best practices. 



Learn from others, then implement best practices on your projects. 3 Legacy Software Modernization Case Studies and 12 Lessons We’ve Learned 



We cannot fail to mention here test-driven development (TDD) and behavior-driven development (BDD) that stand for effective software engineering. While building your solution from scratch, it’s recommended to use these methodologies as developers and testers can start with a clean slate without breaking anything.











 VIEW CASE STUDY  











From other perspectives, it’s almost impossible to use them with other software modernization approaches like refactoring or rehosting. The risk of breaking the app is abnormally high.  



Most developers won’t touch your legacy codebase. It’s as they say… “very scary.” That’s where ModLogix comes in to offer you a cost-effective alternative to testing and refactoring legacy code. To get you started, you’ll receive a legacy platform code audit for your product.



How to Test Legacy Code: Avoiding Common Problems



One of the main goals of testing legacy codebases is to clean up code and avoid regressions - breaking things by accident. To give more insights into how to test legacy code, here are some of the most common problems you’ll face, and their solutions.







Hard-wired dependencies



This occurs when you have loads of classes that were not written to be tested. You cannot isolate these dependencies. For example, a static class that makes reference to another class B with special requirements, such as the need for the system to be deployed on a web server. 



Solution:



Use SEAMs to bypass the hard-wired dependency between 02 classes. 



“A seam is a place where you can alter behavior in your program without editing in that place.” Michael C. Feathers - Author of the book: Working Effectively with Legacy code.



According to the author, there are different types of the SEAM model, such as Preprocessing Seam, Link Seam, and Object Seam. Thus, you can choose the preferable variant depending on the source code and the language.







Problems with understanding elements of the codebase



Given that legacy is often written by someone else or probably a long time ago, you should face problems understanding elements of the codebase.



Solution:



If you’re wondering how to write unit tests for legacy code, that may be what you should avoid; and focus on broader tests already mentioned above. Once you understand what major sections of the code are meant to do, it becomes easier to write automated tests.



Characterization Testing



The characterization testing technique is another solution to the above problem. Here’s how it works for a particular code section under test…




Assume that the code is providing the right output.



Write a test, expect a random value… say ‘100’. See what value comes back in the test failure method. Then change your tests so that you have the expected value.




You can do this for all methods you’d want to test.







Should you test or debug?



You’ll be faced with the challenge of whether to write and run tests first or preferably debug code.



Solution:



Troubleshooting code to find bugs, and then decide. How do you decide? You should fix the bug if…




It is simple, obvious, and local.



You understand the code where the bug appears.



You understand the fix.




Otherwise, spend time expanding your test suite.







What to test?



There’s a lot to test, so it can be confusing where to begin, what to prioritize, and what to ignore.



Solution:



Focus on the main path of the application, not the edge conditions. Start with obvious inputs/test conditions (say 5!... for a factorial method). As the test suite expands, start looking at the edge cases - especially if you get a bug report.



You’ll still need tests for the main path of the application.

### Technical Debt Reduction in Legacy Systems: How to Do It Efficiently

When you prioritize quick delivery over good code quality and organization, the result is technical debt. You are trading off long-term benefits over short-term results.



According to a Stepsize survey, 58% of companies don't have a process to reduce technical debt, despite 60% of engineers warning about its negative impact on business. Code debt, especially that which is deliberate, can be super dangerous for your software product! 



Technical debt makes working on older systems harder than necessary. It's an unpleasant reality for devs and business owners. More often than not, the cost of technical debt significantly increases over time; which means the earlier your organization starts to deal with these loans in your codebases, the better. 



Legacy systems are no stranger to technical debt and have a large pile of unpaid technical debt which must be reduced to make updates easier and faster, as well as increase the quality of the product. 



Read on to learn more about technical debt, common causes, best practices to tackle this debt, and solutions for technical debt reduction with legacy codebases.



Understanding Technical Debt in Legacy Systems



What is technical debt in legacy systems? Legacy code has been around for too long. Technologies, user needs, project requirements, and programming techniques are constantly evolving, and so should our codebases as well. 



Technical debt in legacy systems refers to the amount of extra work required to effectively modernize these legacy codebases – making them maintainable, and scalable.











Technical debt is inevitable in legacy systems for the following reasons outlined:




Legacy code is relatively old, built on somewhat out-of-date technologies that may limit growth.



Legacy code might have been implemented hastily and unprofessionally. 



The legacy code was built by hundreds of developers, each bringing a different programming technique - making the code unmaintainable.



The absence of a suite of automated tests in legacy code is another major technical debt hole that needs fixing. 




The major problem with technical debt in legacy code is the maintenance cost. Technical debt makes it so difficult and expensive to add new features to legacy code or change existing modules without breaking the system. No business owner wants to overpay for their software.



Legacy software drains your IT budget! Read how much you overpay for it. The Cost of Maintaining Legacy Systems: How Much You Overpay 



Common Causes of Technical Debt



What are some of the main causes of technical debt in legacy code? 











1. Design decisions







The design decisions that were made when your developers wrote the code for the first time are a leading cause of the current technical debt your codebase is facing. These decisions may have been good ideas at the time, but they may no longer be appropriate or even safe for present times. 



For example, maybe your developers chose to store everything in one database table when they wrote your system because it was easier than splitting things up. Yet today, putting all that data in one database is obsolete.



How to avoid technical debt? Start by making thoughtful design decisions at the planning stage of the development process. Future planning is essential for reducing the amount of technical debt that will be buried in your codebase over time.







2. Poor communication of project requirements







Code that is implemented without a clear understanding of the requirements will result in technical debt. This can be caused by a misunderstanding or miscommunication among stakeholders, a requirement that wasn't properly documented, or the absence of documentation at all. While among the key benefits of legacy code documentation are the availability of the project specifications and faster releases or bug fixes. 







3. Low test coverage







Technical debt is also caused by poorly written tests that do not cover important functionality, perhaps because they were written before the actual functionality was created (or maybe never written at all as is the case with legacy codebases). Maybe your team did not have enough time to write unit tests, and now your codebase has lots of bugs that need fixing before it can be refactored into something more modern.







4. Poor development practices







All businesses work with deadlines. Your need for a final product to be delivered as quickly as possible lures developers into ignoring best practices, and prioritizing speed instead of code quality. The obvious outcome is technical debt.



Learn from others, then implement best practices on your projects. 3 Legacy Software Modernization Case Studies and 12 Lessons We’ve Learned 



5. Team lags behind







When your team fails to learn, upskill, and catch up with new technology, the result is technical debt. Technologies move so fast; over 3-5 years, the technologies on which your systems are built become obsolete. Your in-house developers should be in the capacity to learn these new technologies and programming techniques, to modernize your legacy codebases. Investing in your team is one of the best investments you can make as a business.







In summary, technical debt is dangerous for the following reasons:



New features become more difficult to add.




Features that should be simple become complex and time-consuming.









When a new feature requires changes in multiple parts of the system, the cost of change increases exponentially.









New features take longer to build and can't be used until they're finished.









Testing becomes more difficult and expensive as more complex features are added to the system.









The code will increasingly be harder to understand and debug, which slows down development even further.




3 Major Benefits of Reducing Technical Debt



If your product must scale and improve in quality, your team must work hard toward eliminating code debt from your legacy codebase.  The benefits of reducing technical debt in legacy codebases can be broken down into three major categories:











Productivity



Reducing technical debt makes it easier for your team to produce new features, fix bugs, and ship quality software. It also improves their morale, as they can deliver more value faster.



Product quality



A well-designed system can accommodate a larger feature set than a poorly designed one (see Conway's Law). Therefore, reducing technical debt can help you build better products that are less prone to bugs and security vulnerabilities.



Maintainability and scalability



A well-designed codebase is much easier to expand and maintain than an ill-conceived one. Reducing technical debt reduces the cost of future maintenance by making it easier for new developers to understand your codebase and adopt new technologies.



Another important benefit of reducing legacy code is the fact that it saves your business money and resources in the long run - money that would otherwise be channeled towards writing a new codebase.



Effective Technical Debt Reduction Strategy for Legacy Code 



According to an Accenture survey, 72% of C-suite executives state that their legacy systems hamper their ability to migrate to new technologies and make their IT functions less responsive to market change. That means that technical debt and legacy code negatively affect the digital transformation and evolution of your business as well. 



Here are some of the best strategies to reduce code debt in your legacy codebase.



#1 Identify technical debt: Deep dive into system architecture



The first step to reducing technical debt is to identify it. But how do you know where to look? A good place to start is to look at your system's architecture: make a code review.



Looking for proven ways to create a modern software architecture? Read our post with answers. Consider These Things Before Legacy Application Re-architecting 



The architecture of any software system tells a story about its evolution. It reflects the decisions made by developers in the past, and those decisions can have an impact on future development efforts. When you're assessing your system's flexible architecture, keep in mind that too much change can be just as problematic as too little change. The trick is finding a balance.



For more in-depth and effective analytics of your codebase/architecture, you may want to get a professional source code assessment service to take a look. ModLogix also offers advanced legacy software audit services that will help you perform a thorough analysis of your codebase.



Once you've identified the areas within your architecture that need improvement; you’re ready to take the next action.



#2 Refactoring legacy code to reduce technical debt



A better option for rewriting legacy code is to refactor the existing code so that it solves its original business problem more effectively. This approach reduces technical debt by making the code simpler, more maintainable, and less buggy. The goal of refactoring is to make it more readable, and easy to change and test.



There are several strategies for refactoring legacy code:






Separate concerns into small modules.




The idea behind this strategy is that you should always have small modules with a single responsibility. Split modules with more than one responsibility into smaller modules. Each of these smaller modules should have only one responsibility and should be small enough so you can read it in one sitting.






Use dependency injection instead of hardcoded dependencies.




Dependency injection is a design pattern where you inject the dependencies into your objects instead of passing them as parameters or setting them in the constructor. Dependency injection allows us to replace any dependency with another object while keeping our code clean and simple at the same time.





#3 Investing in human resource



As a small business, your team, however small, is your biggest asset. Yet technical debt emerges when technology evolves but your team doesn’t evolve with it. It is primordial to help your team move up the ladder by learning new skills and technologies following the rapid advancements in tech. Do this by creating training programs and growth opportunities for your software developers, product designers, and software architects.



How to Reduce Technical Debt in Legacy Platforms: 5 Best Practices



When it comes to legacy code, there is no one-size-fits-all solution. The best way to reduce tech debt there is to understand your system and its codebases from A to Z, and then decide how to handle the situation accordingly.



#1 Track and document technical debt



The first step is to create a technical backlog of features, fixes, and bugs that need attention - and then develop a workflow. You can use tools like Confluence, JIRA, or Trello - to develop your technical stories on the backlog. This will help you track what needs fixing and when - by creating project milestones with due dates attached to them. You can then add specific issues related to each milestone so everyone knows what needs fixing in which order. Keeping track of a technical backlog should become a regular part of your schedule as a team.




Look at your project backlog and identify all the technical debts that need fixing.









Break down each one of them into smaller tasks based on complexity, the time required, etc.









Create a document for each task with details like description, owner, etc., date started, and expected date of completion.









Create another document for the whole project detailing all the tasks that need to be done with due dates etc., so that it can be used as a reference point for everyone involved in fixing these issues.




#2 Get your test coverage up!





Poor testing is what got you here in the first place. The healthiest approach to dealing with legacy code is to increase test coverage as much as possible. Even before you begin refactoring, make sure your developers are writing as many automated tests as they possibly can, but don’t aim for 100% coverage. 





Preferably, your developers should go for the bigger functionality and integration tests. Getting a working, automated suite of tests really irons up legacy code, enables stability during code changes, and significantly reduces technical debt.





How to test a legacy codebase without breaking anything? Learn here. Testing Legacy Codebase: What is, Common Problems and Best Practices 



#3 Manage dependencies wisely



When you're building a new feature or fixing an existing one, make sure that you're not going to introduce any new dependencies or break existing ones. 



For example, if you're building a new feature that depends on a third-party library, consider using an in-house version of that library instead of relying on an external one. If you do need an external dependency, make sure it's well-documented and easy to maintain.



#4 Avoid changing core logic



By all means, avoid altering the core logic and architecture of your codebase. If there's no other way but to change a certain piece of logic in your system, try isolating this piece of logic into its module so that other parts of the system can remain unchanged as much as possible during development. This will help avoid breaking existing features or introducing new bugs during future refactoring efforts.



Don't add more complexity than necessary when refactoring code; keep things simple!



#5 Start small



The best way to get started with reducing technical debt is by fixing existing technical problems one task at a time. Don't try to fix everything at once — this will only frustrate you and make it more difficult to see progress. Pick one task that needs fixing and focus on that until it's done — then pick another backlog item and keep going until you've got it all under control.



Another important best practice is to get rid of code that doesn’t work anymore, as long as it doesn’t affect the core logic of your application.

### Legacy Software Re-engineering: Risks and Mitigations

It does not matter how well your current product is built if it is not supported by a well-designed software development process. Every software product becomes obsolete at some point in its lifetime and stakeholders have no option but to upgrade or discard it. 







New devices, software, and operating systems are being released all the time, creating an environment where old software no longer works as it did a few decades back. As a result, many businesses have turned to software modernization for the following reasons:




Cost - the costs of maintaining legacy software far outweigh its benefits.



People - an ever-growing workload on in-house engineers and a shortage of qualified specialists to keep an eye on outdated technologies means that more resources have to be spent on newer products.



Security - legacy code is easily vulnerable to cyber-attacks because it lacks security updates. Besides, old software may not comply with modern regulations.



New technologies - outdated technologies have limited flexibility to integrate with other technologies, making it harder or even impossible to customize the application and add new features.




When a business decides to modernize the software application, there can be three general approaches to solve the problem:




Move somewhere, for example, to the cloud or a new platform, or refactor some parts.



Change something in the codebase – this involves restructuring and cleaning up the code and or changing its architecture and programming language.



Change everything - a complete re-engineering of legacy software could mean having to rewrite the application from scratch.




In this article, we’ll focus on legacy application re-engineering, the pros and cons for enterprises, and how to create an effective and up-to-date re-engineering strategy.



What is Legacy Software Re-engineering?



Legacy software re-engineering is one of the effective software models to solve the legacy app issues and modernize the outdated code.



There seems to be no universal definition of what software reengineering is. Different authors imply various techniques when talking about re-engineering. Starting from the software maintenance automation and even all activities performed after the software implementation. In our opinion, the most relevant definition of the re-engineering process is understanding and changing a legacy system, and after that, reconstructing and implementing it in a new form.



Legacy System Re-engineering vs. Other Software Modernization Approaches



As mentioned earlier in the introduction, the software modernization problem can be solved in the following ways:




Move - migrate the application to the cloud or to a new platform.



Change something.



Change everything and rewrite the application.




Are you choosing between rehosting, rewriting and rebuilding? Read this article. Should You Rehost, Rebuild, or Rewrite a Legacy Application With Latest Software? 



Let’s explore each of the software modernization approaches in depth. 



Moving the application. This means moving the application “as-is” to a more modern environment. For example, from on-premises to cloud environments or moving to new hardware entirely. It is useful when the company resources are limited, and the code is relatively well-built. In most cases, when you need to migrate .NET Framework to .NET Core, the process involves well-defined steps without a total system makeover.     



Such an approach uses rehosting or replatforming techniques. Their main benefits are the following:




Minimal changes in the code,



No change in the core features,



Moderate resources and expertise are required to do everything promptly.




However, there are obvious disadvantages of the given approaches:




Migration may entail porting code errors and legacy components into the target system



The owner can’t adjust the software to its needs;



Can’t expand functionality on the go.








Changing everything. In comparison to legacy system re-engineering, this means software redevelopment - starting from rethinking business requirements, redocumenting, and even rewriting the application. This does not mean the whole application at once but incrementally throughout time. It can be useful for extremely problematic projects, in which there is no technical or business documentation, no original developers, and no robust software architecture. 











Such an approach uses rewriting and rebuilding techniques, or total replacing - using a third-party alternative product with utterly different infrastructure. As an example, it can be complex re-architecting of monolith systems to service-oriented architectural style. Oftentimes, organizations apply a split of these software modernization services to achieve better results.



Learn how to rebuild old monolithic software with microservices. Microservices Architecture Advantages and Disadvantages, Risks, and 5 Use Cases 



Their main benefits are as follows:




Significant changes and introduction of new features,



Revision of project goals and business processes,



Future-proof solutions.




The challenges and pitfalls of changing everything in software are also substantial:




Large upfront cost, 



A complex procedure that requires expertise and a reputable software modernization vendor who will be able to answer all of the questions on legacy application modernization,



High-risk approach.








Changing something. Finally, we get to the bottom of things! Here’s where software reengineering comes to play. This approach concentrates on improving the technology itself either modifying the software architecture or the code structure and refactor problematic code pieces. It requires highly skilled engineers and a software architect for the project. 



Re-engineering of legacy systems is used when the codebase is far from perfect, and the team can justify the benefits of new technologies for the enterprise. This is probably the most common case with a vast variety of implementation techniques. Legacy software reengineering has the following main benefits:




Increased performance,



Code transparency and predictability,



Overall software enhancement,



Reduced maintenance costs.




What about the major drawbacks of this approach?  




Lack of documentation can lead to poor programming decisions,



Require a dedicated team that’s familiar with the system.




Legacy Software Re-engineering Process



Re-engineering legacy system includes three stages:




Reverse engineering



System transformation



Forward engineering












What’s hidden inside this terminology?    



Reverse engineering (backward engineering or back engineering). This is the key point of software platform re-engineering, which is the understanding of the initial program. Depending on the nature of software properties to be discovered, reverse engineering performs a static or dynamic analysis.




During the static analysis, programmers examine the source code and create data structure representations.



The dynamic analysis is done during the code execution.




The result of reverse engineering is a set of abstract representations of the software system under consideration.



System transformation. This is the second stage of legacy software re-engineering. In the system transformation stage, the abstract representations obtained during the reverse engineering are further transformed into other representations at the same abstraction level. The aim is to improve the software structure, quality, and stability. The system transformation stage includes the following processes: refactoring, rearchitecting, and rewriting.




Refactoring - is restructuring the code at the level of methods and classes.



Rearchitecting - is refactoring at the level of modules and components.



Rewriting - is rearchitecting at the highest possible level.




UI/UX redesign is another crucial step on a way of the digital transformation. Risks and Approaches of Legacy Application UI and UX Modernization 



Forward engineering. After system transformation, the transformed system representations can be used to generate physical implementations of the initial system - at a low abstraction level. Forward engineering starts with system specification and includes the design and implementation of a new system - like an ordinary software development process.



This step completes the re-engineering legacy application process where the renewed software meets the ultimate criteria of upgrading. 



When It's Time to Re-engineer Your Legacy Software



Software re-engineering as one of legacy system modernization approaches is simple - not to rework the whole application while also being effective enough to improve the codebase. Consider re-engineering the software system in the following situations:







You want to save resources:




reduce the maintenance cost,



reduce the load on the qualified engineers,



save time - compared to redevelopment.




You want to clean up the codebase and remove the code “bad smells”, for example:




duplicate code



very long methods



not-needed generality



commented-out and expired code



dead and zombie code



non-testing and falling tests



null references and unnecessary mutable states.




You have ambitious future plans regarding your software:




switch to a modern technology



migrate to another platform



introduce new features



update the business logic




For example, AngularJS to Angular migration, that’s considered a platform upgrade entails rewriting and, subsequently, legacy software re-engineering services. Although these frameworks have common roots, their architectures have a world of differences. That’s why re-engineering the system is one of the most crucial steps to migrating to a reliable platform that we’ve described in our case study. 



Risks and Pitfalls of the Legacy Application Re-engineering and How to Mitigate Them



Software re-engineering is a complex task that has its risks and legacy system migration challenges:



Development issues. Highly-skilled developers are required for this task. Initial developers have already switched to other projects or even left the company. However, the company typically has no money to hire new professionals and no time to teach the low or medium-skilled employees.



Management issues. Legacy software maintenance can stop being a top priority for businesses. In such a case, the top management loses interest in the software support, and it can be hard to justify the need to spend on updating the working code. Possible advantages are remote and not clear to stakeholders.



Cost risks. It can be hard to make exact cost predictions for the legacy re-engineering project due to a lack of expertise and documentation. It can become even more complicated because there is typically a need to expand the existing functionality, and at the same time, maintain compatibility with previous product versions.



Potential threats of changing environments. It is always risky to perform “live” changes in the working functionality - in real-time in production environments.



At ModLogix, a legacy software modernization company, we work with the whole spectrum of software modernization approaches, including application re-engineering. So far, our team knows all of the ins and outs of the re-engineering process, and we are eager to share our expertise in dealing with some of the most challenging projects.   







 VIEW CASE STUDY  







To mitigate the possible software re-engineering problems, we recommend the following preventive measures:




Try to gather the dev team with the senior architects and designers.









Make only minimum, necessary, and sufficient corrections and enhancements to the core logic.









Restructure the code and data to remove unnecessary complexity - to make the codebase manageable by the available human resources.









Perform code modifications step-by-step, not for the whole application at once. Select code parts for re-engineering thoroughly - only the most critical and less risky ones.









Automate everything that can be automated.









Document all the changes - not to generate a new legacy.









Communicate with all the parties involved in the re-engineering process - to clear the goals and available resources.









Report about the results as early as possible - to confirm the necessity of expended resources.




Final Thoughts



Software re-engineering helps to eliminate or at least reduce the inevitable legacy code risks, such as the departure of key developers, deeply-hidden bugs, server overload, overwhelming maintenance costs, and more. As with any methodology, it should be used carefully and adapted thoroughly to the particular application, its main tasks, and business processes.



Keep balance. Software improvements must not turn to 'programming for the sake of programming'. Don’t forget that the software works to solve users’ problems, but not to improve the development process itself, thus making it beautiful and convenient.



Keep calm and use force. Involve the team experience and prepare the dollar-based argumentation - to convince the business of the validity of the legacy software changes. Be consistent and patient, get ready to convert technical problems into measurable business metrics this way you can explain the necessity of long-term investments.



Speaking of the force. If there are any difficulties in preparing for legacy software re-engineering in your company, contact ModLogix professionals for a free consultation. We believe that there are no complex systems, but there are real experts who turn challenges into solutions.

### 7 Foolproof Ways to Reduce Your AWS Costs in 2023

A recent study by Canalys notes that the global expenditure on cloud infrastructure services increased by 36% to $47 billion in the second quarter of 2021. Amazon Web Services (AWS) dominates the global space with a 33.8% market share. From these statistics, you can tell that AWS is a go-to option for many organizations focused on resiliency planning, which demands expedited digitization with increased cloud usage. Moving legacy software to AWS also allows app re-platforming to ensure continuity in the cloud environment, maximizing the benefits of the new infrastructure. 



However, in a bid to experience the benefits of cloud computing through migration from legacy systems to AWS, businesses often face various challenges, such as high upfront investments and growing bills after migration, which can be perplexing to a typical business owner. That said, optimizing AWS costs sounds like a good plan for any organization. Here is a quick guide highlighting what AWS cloud cost optimization entails, when to think about optimizing AWS costs, 7 best practices for getting started with cloud migration services, and AWS cost optimization checklist.



So, What is Cost Optimization in AWS?



Cloud cost optimization entails reducing the overall expenditure your business incurs on AWS cloud computing by spotting mismanaged resources, reserving capacity for better discounts, reducing AWS data transfer costs, and eliminating waste. 



Top analysts from Gartner, Craig Lowery, and Brandon Medford note that businesses waste up to 70% of cloud costs unknowingly. There are various factors affecting AWS cloud cost, so let’s distinguish some basic service types which ultimately create AWS cost estimates:




AWS server type; 



Number of servers;



Database usage;



Storage capacity and size;



Data transfer costs;



Domain costs. 
















Cost optimization techniques in AWS help your business cut its cloud computing budget while maintaining the required performance and capacity. In the long haul, these cost optimization practices help your business achieve the highest saving potential in a bid to realize its overarching goals. Doesn’t it sound prudent to save a couple of thousands and use the budget to expand your organization?



When It’s Time to Think About AWS Price Optimization



Typically, the burden of AWS cost optimization lies with the business owner. But how do you know that it’s time to reduce your AWS operational costs? You need to be wary of some costs that seem to be out of control. 



That said here is a detailed breakdown of AWS costs:



EC2 instances - virtual servers in AWS Elastic Computing Cloud that allow customers to run applications on the infrastructure. 



EC2 instances on your AWS server account for the biggest costs, about 62%. The most expensive EC2 instance is the p3dn. 24xlarge. Running it on a Linux OS costs about $31.212 per hour and $35.628 per hour on a Windows OS. 



EBS (elastic block storage) - EBS is a block-level storage solution used by AWS customers alongside E2C cloud service to store persistent data. EBS storage can account for up to 8% of AWS costs. Here, AWS can charge you for restoring EBS volumes and snapshots. 



RDS - Amazon Relational Database Service (RDS) facilitates the setup, operation, and scaling of relational databases in cloud infrastructure. RDS can account for 7% of AWS costs. AWS includes the costs of Oracle database licenses in the RDS service price since customers don't have to bring their licenses. 



Other services - Other services, such as outbound data transfer, storage, and computing may account for up to 17% of AWS costs. 



As a result, unreasonably high storage bills might mean that your infrastructure stores obsolete EBS (elastic block storage) volumes or the cloud sizing doesn't fit your needs. Either way, you can track cloud costs on your Billing and Cost Management console, but it wouldn’t be helpful unless you know the specific ways of AWS costs optimization.



7 Ways to Reduce AWS Costs



AWS customers can enjoy cloud computing services under various EC2 pricing models such as On-Demand, Spot Instances, Reserved Instances, Savings Plans, Dedicated Hosts, and AWS Free Tier which comes with several limitations. 



Price optimization comes in after understanding the services you consume. Here are expert insights on how to reduce AWS cost efficiency for each model. 















1. Check for AWS Savings Plans



Some businesses are pretty stable and can predict their resources requirements over a certain duration. If that is the case in your business, you can start cost optimization on AWS by making annual commitments for Fargate and EC2. That means you are promising to use a steady amount of cloud computing services between 1 to 3 years. 



EC2 launch type



EC2 launch types give AWS customers greater control over how they can customize their cloud environment. For instance, you can leverage EC2 launches to configure your cloud environment with regard to the underlying business needs in terms of network, GPU, and security. 



Fargate



Fargate launch types come in handy when building and maintaining containerized applications. With Fargate, you can match resources with tasks to minimize the need for server management, or enhance security by isolating applications by design. 



In general, you can reduce your AWS costs even more by choosing the All Upfront payment plan lasting for 3 years. Typically, you make one upfront payment and benefit from a steep discount of up to 63% in the third-year term. This is especially if you have everything figured out pretty well, including seasonal demands for your product or service to ensure that you only pay for your required usage. 



Has the time of cloud migration already come? Check how you can estimate transition costs. . How to Estimate the Cost of Cloud Migration 



Tip from ModLogix, note that the service provider will charge any extra items beyond the agreed usage or limits at the usual on-demand rates. That said, it’s prudent to get your forecast right. Opt for an annual commitment to minimize exceeding risks.



2. Consider Architecture Improvements



Not all guides on how to reduce AWS costs will tell you about architecture improvements during cloud migration as viable options.





But in the real sense, modern architecture types, such as multicloud computing by leveraging various service providers can help balance your cloud spending. For instance, it can be possible to optimize specific service-level requirement costs by partnering with different cloud vendors, such as Azure or Google Cloud.





Alternatively, you can opt for hybrid cloud computing by leveraging both on-premise and cloud infrastructure. In that way, working on the existing servers, power supply, and cooling systems, or networks can minimize the costs associated with porting the applications to a cloud environment.





These practical tips for re-architecting help you make software systems extensible for future growth. Consider These Things Before Legacy Application Re-architecting 



3. Eliminate Unattached EBS Volumes and Aged Snapshots





Launching an EC2 instance comes with an attached EBS (Elastic Block Storage) as the local block for storage. Every time you launch an instance, an EBS is attached to the storage, which can translate to thousands of unnecessary EBS volumes, increasing costs beyond your anticipated budget. 





Remember, AWS still charges for storage capacity, even if you’re not using the EBS volumes. For this reason, always check the AWS console box to delete these unattached EBS volumes after terminating the instance.





EBS snapshots, which are basically backups of your data, are essential for recovery purposes. However, this is mostly true for only recent snapshots. Think of aged snapshots as obsolete, especially after serving their intended purposes. Unless you delete aged snapshots, you’ll continue paying for them.



4. Get Rid of Zombie Assets



In a layman’s understanding, “zombie assets” are obsolete or unused assets that exist within your infrastructure, contributing to unnecessarily high AWS costs. In AWS and cost optimization, zombie assets are considered as RDS and EC2 instances' failed components and underutilized Elastic Load Balancers. Typically, load balancers are used to distribute system traffic but often cause surges in AWS costs when they remain unused. Consult ModLogix today and terminate zombie assets in your infrastructure to optimize AWS costs.



5. Rightsize EC2 Instances



It's common for AWS customers to incur the costs of what they provision instead of use, unknowingly. For instance, a business with an EC2 instance provision of 8 vCPUs and 16 GiBS memory will pay for this capacity, regardless of what it uses in the real sense. In that case, this business is paying for over-provisioned instances, which can be pretty expensive.  



But how do you right-size EC2 instances? First, you need to: 




Turn off idle instances. You can turn off non-production instances at night and during weekends to save money. 



Understand your memory and CPU usage. Monitor disk I/O, network, disk space, and disk swap utilization to determine what you need to use on average. 



Leverage AWS Well-Architected framework. This tip gives you insights into trade-offs and implications of your decisions to spot opportunities that require improvement.




Choose or migrate to the right instance family. Rightsize to migrate to the right instance family and save costs on infrastructure maintenance.



6. Minimize EC2 Costs



AWS customers can cut their EC2 costs by leveraging Amazon EC2 Spot Instances, especially with a fault-tolerant workload. Spot Instances are cost-effective because they use spare EC2 capacity available for less than the On-Demand model. 



Spot Instances allow you to request unused EC2 instances at discounted rates, lowering your overall Amazon EC2 costs. This move can help you save up to 90% of AWS costs when it comes to specific workloads, such as CI/CD, high-performance computing (HPC), and containerized workloads. 



Other fault-tolerant workloads that can work with Amazon EC2 Spot instances include big data and web servers.



7. Cloud Migration Planning



One of the ways of minimizing AWS costs is by planning cloud migration to minimize unnecessarily high upfront costs. Some of the main areas that you need to address or consider and realign with your budget include resource allocation. 



That said, here are vital tips for cloud migration planning:




Create a data migration plan to minimize future storage bills;



Assume the migration-architect role to determine migration priorities;



Choose the right level of cloud integration — shallow or deep cloud integration;



Decide whether you want single or multi-cloud computing;



Do necessary refactoring first to minimize the actual migration costs;



Find a reliable and experienced cloud migration company.

Essential Checklist for Optimizing AWS Costs from ModLogix



Saving IT costs are among the reasons why companies are moving to the cloud. There are basic cost optimization pillars for AWS regardless of your business size or industry. 







Source: 451 RESEARCH – COST MANAGEMENT IN THE CLOUD AGE







To put it in better perspective, here is a must-have AWS cost optimization checklist. 




Optimize cloud migration costs. It will help if you plan the migration accurately to minimize the costs of cloud migration services first before optimizing the expenses incurred on infrastructure maintenance. Understand the pre and post-migration costs before forging an actionable plan to execute. 




Pre-migration costs include deferred expenses, applications reconfiguration, and onboarding education. On the other hand, post-migration costs may include performance tests, resources underutilization, and security expenses. 








Increase elasticity by leveraging AWS Auto Scaling. AWS comes with an in-built AWS Instance Scheduler to automate your Amazon RDS and EC2 instance's start and stop plans. That way, you can shut down instances during off-use hours. 









Rightsize your instances with regards to the current resources in use. In other words, rightsizing entails going for the most affordable instances that match your business performance needs. In that case, consider how you utilize RAM (Random Access Memory), storage network, and CPU (Central processing unit). 









Leverage the right cost model within your budget. Take advantage of the AWS Cost Explorer to understand the right on-demand, spot, and reserved instances using EC2 pricing models. Even better, you can use the Trusted Advisor feature to ensure you get this right from the word go. 









Optimize your storage by deleting obsolete EBS volumes and snapshots. This saves you the costs of storing what your business no longer needs. Besides establishing a routine for optimizing storage, you can also leverage AWS cost and reporting tools to monitor unwarranted charges on storage. 









Use cost-effective resources, including instances and workloads. In that case, AWS Managed Services can come in handy to help you implement this. 









Measure results and optimize over time.









Include cloud financial management practices in your AWS cost optimization best practices. Cloud financial management, also known as FinOps, entails leveraging cloud-combining systems, culture, and best practices to understand cloud costs. 









Work with a trusted cloud migration vendor who will lead you through all the vital processes at reasonable rates.

### Legacy Database Migration: Effective Data Migration Plan

Upgrading and modernizing basic workflows and software systems is an essential step for any business that scales and adapts to shifting market demands. It is extremely important to keep all the existing and previously accumulated data intact and well-compatible with upgraded systems. For this, savvy companies migrate data from legacy database systems to new, up-to-date performing storage environments. Let’s dive into more details and figure out how to do data migration the right way.

What is the Definition of Database Migration?



As you probably know, legacy data is historical data that’s buried in old databases and contains vital information for the organization. Being stored for ages, the legacy data becomes disordered, siloed, and segmented by different formats. Managing and processing such data becomes overly cumbersome and useless over time, making companies consider moving legacy databases to modern environments.



Database migration is a transition from an older database (DB) environment to a newer, more advanced system (e.g. cloud) while saving data value. Most of the time, data migration from legacy systems to a modern database means:




upgrade to the latest version of the existing database (homogeneous migration);



transfer to a completely new database from another vendor (heterogeneous migration, for example, from MySQL to PostgreSQL).

But how do you find out if you use a legacy database? Here are common examples of legacy databases:




MS-DOS-operated proprietary software/hardware combinations (the oldest type of legacy systems);



computerized library systems;



your MySQL, Microsoft SQL Server, PostgreSQL, Oracle, or another database — if it is running on an IT infrastructure that hasn’t received proper updates for some time. 




If you are experiencing issues handling any of the above or having trouble defining the most fitting migration approach in your case, contact ModLogix for professional consultation on any questions on legacy application modernization.



5 Benefits of Database Migration 



Now let’s define the main benefits of legacy database system migration.







Cost reduction



Legacy systems run on stale software that must be scrupulously maintained and upgraded with the help of extra integrations and whatnot. And the maintenance and optimization of such systems requires additional expertise and manpower while tinkering with out-of-date software is always an overly time-consuming process. All of which results in significant yet unnecessary expenses. On top of that, the legacy infrastructure has limited capacities, which hinders business expansion by restricting technical scaling opportunities.







Timely migration is what can help you avoid both extra costs and tech restrictions by achieving a system that’s more flexible, secure, and overall reliable in terms of the underlying infrastructure. A migrated and modernized system runs smoother, employs updated security mechanisms, and is easier to support. Streamlined software performance goes a long way, reflecting on the end quality of services.

Capability enhancement





The migrated data gets an advanced environment that is based on a more versatile, reliable, and powerful software architecture. This enables companies to adopt new, efficient data storage approaches and techniques to boost the quality of data-driven decision-making. And the better, more in-depth grasp a company has on the underlying data, the more informed business decisions it can make. 





 A new system, especially if it is custom, can help you perceive and analyze data in a dozen proven ways which your legacy system used to restrict. In general, an efficient set of data management tools streamlines data manipulations, making data scientists’ and other specialists’ lives easier and smoothing out an initially complex workflow aspect.  





Data accessibility





As the amount of data grows and your business expands its physical and/or digital presence, you may need to bring that data to a new level of availability. And achieving all-around data accessibility is the major advantage of migration to the cloud environment. Today’s cloud software capacities allow for reliable, high-performance data storing and processing while data access becomes mobile and universal. 





 A cloud database can be accessed through a variety of devices - all you need is a web connection. On top of that, you can forget about the data transfer latency characteristic to local physical servers. Lastly, there are flexible and simple scaling opportunities where hosting providers expand the cloud to any required extent. 





Comprehensive data integrity



Legacy database migration preserves data dependencies, allowing developers to conveniently redesign the system. This means that the data remains integral, and the default access settings are saved. The overall data integrity is paramount as the quality of data translates into the quality of decisions made based on that data. And such decisions are usually crucial for setting the business direction and achieving better market results based on the detailed analysis of demand and trends.



Organizing data in legacy systems often turns to a real challenge. Learn How to Effectively Conduct a Legacy System Integration 



Versatile scaling



Without causing any essential proprietary difficulties, a cloud system can easily be scaled to accommodate more users, manage more tasks, and cope with higher performance intensity. All of this is possible because cloud capacity can be scaled to almost any level on the provider's end. To scale quickly, you don't need to worry about all the server/storage/network equipment management, licensing, and other administrative tasks. This comes in as a real time- and nerve-saver.



What Are the Main Data Migration Requirements?



Finally, we got to the stage of discussing the data migration requirements that must be met before proceeding with the migration procedure.



Data audit



A legacy database is a poorly structured, heterogeneous, and often unused set of data. In order to eliminate errors in the dependencies between these data sets after the upcoming migration, you have to audit them. If you ignore this step, unexpected problems may arise. In addition, you should understand that you need to move not only data but also the business logic implemented on the database side. 



You should be careful here: business logic in the old system can be written in various programming languages; therefore, simply copying it to a new system means transferring all existing errors along (and possibly adding new ones).



Solving data issues





If there are any problems with the legacy database, they need to be fixed even if you migrate the whole data set. To do this, you probably need a separate service — code refactoring. In particular, when migrating, you need not just swap one database management tool for another, but conduct a "cleanup" of the data to ensure its consistency, integrity, and non-duplication.





If these conditions are not fully met, then you need to make sure that the specialists performing the transferring from the legacy database are aware of this duplication and its reasons. Otherwise, if during the transition from a legacy database to a new one a data loss/duplication appears, in the future, this may cause errors in the operation of the system.





Maintaining data security



Databases are one of the most vulnerable targets for cyber attacks. However, there are various tools on the market today to make data transfer secure, such as intrusion detection systems, security analytics, and firewalls.







In addition, your team needs to understand what data they will have to deal with and how it will be used within the system. Ignoring this step can lead to a fatal data mapping error.



Track data quality and generate reports



The state of the existing database and reporting on the data stored in it must be monitored. At the same time, the processes and reporting tools should be convenient and, where it is possible, automated.



7 Steps of Data Migration Process



So, how to migrate from legacy database? According to our experience, this process involves seven consecutive stages. Below we will look at each of them.







Audit the legacy database



Before the migration procedure, you must carefully analyze the data with which you are dealing: what is the structure of this data? What is its type? Does it have dependencies? What fields are missing? Perhaps some of them are no longer used, and there is no need to migrate these data from legacy database to a new database. If some parameters are missing, they will have to be replenished as far as possible so that the system will work correctly in the future.

Plan your migration scenario



You have two data migration techniques: Big Bang (the first of two data migration approaches that implies stopping the business processes in which the old database is involved; runs within a strictly predetermined time frame) or gradual migration (this data migration approach does not require suspension of work processes). At this stage, after choosing which one of the types of data migration is the most suitable to your needs and tech requirements, you also need to select the appropriate migration tools and complete a list of specifications (including security).



Make the data backup



Do not forget to back up your data so that in case of incorrect migration you can return to the previous steps without loss. Data backup is a timely effort to copy all the migrated data and store it someplace to easily recover any lost or damaged assets in case certain mid-migration issues take place.



Design the target system



With the backup in place, the data can now be moved to a new better environment. The essential step of the way, however, is to have that environment running and ready to receive all the migrated data. The migration solution can be custom-made or readymade - depending on your needs and goals, you may want to build a tailored solution for more versatility or use a readily available platform for fast and cost-efficient migration. The final solution depends on your goals and resources.



Test your new database



Test the new database with real data at all planned stages (not just at the end of the migration procedure). For instance, when it comes to migrating large amounts of data, database migration testing can be done synchronously with all the steps of data migration. This is how you can understand how correctly the procedure was carried out and see whether everything runs properly (business logic, connections, etc.).



How to test a legacy codebase without breaking anything? Learn here. Testing Legacy Codebase: What is, Common Problems and Best Practices 



Run the updated solution



After a successful final testing procedure, you can launch the updated system for public use. This is where you also may need profiled assistance to properly deploy software in the required environment.



Support and maintain the system



During the first weeks of the updated system, you can continue to test it using automated tools to eliminate the possibility of errors. Post-release support and maintenance help further adapt the system to new working conditions and perfect its performance.



What Determines the Cost of the Legacy Database Migration Procedure?



The pricing of the legacy database migration process depends on several factors:




the amount of code running on the side of the legacy database;



the amount of data stored in the legacy database;



the time allotted for switching from one system to another;



semantic differences in the programming languages ​​of the legacy and new database.












The cost of the procedure may increase if you still need to support and maintain the existing legacy database while preparing for the upcoming migration. The migration process is also often associated with architectural improvements to the legacy database, which also implies additional costs.



5 Common Pitfalls in Data Migration



As the practice shows, even if you have a well-thought-out, thorough plan, you may still come across certain pitfalls. This is why it is especially important to come armed with knowledge about the most common pitfalls.



Poor data quality 



The most global complexity in the migration procedure is bringing the data to the desired quality. That’s why it is essential to pay special attention to the analysis of data and its relationship with the business logic of the existing system. Otherwise, duplicated data or, for example, data presented in a binary code can provoke errors in the operation of the updated system.



Lack of expertise



Alternatively, you may face a lack of qualified personnel who can fully understand the logic of the new and old system. To complete the migration, the hired team must be competent in both the existing database management tools and the target ones. This significantly saves time and reduces the risk of errors. But even with the redundancy of the IT services market, there are few teams who are able to choose the data migration strategy correctly.

Low speed of SQL queries processing



Many organizations face the problem of insufficient SQL queries processing speed even after data migration from legacy systems. This flaw can be addressed with dedicated performance optimization tools such as Ever SQL Query Optimizer, My SQL, Maris DB, and Percona DB. 



You can also initially allocate excess memory resources to maximize the processing capacities of the system when needed. In exceptional situations, data defragmentation can be a way out.



 VIEW CASE STUDY  



Cross-object dependencies 



Despite the plethora of legacy database transfer tools and strategies, cross-object dependencies can still be often discovered only after the launch of a new system and thus entail additional rework and time costs. Profiled specialists can employ a number of approaches and tools to cope with them. The main thing is to do it all timely.



The first testing procedure comes with unexpected outcomes, scenarios, and unexplained problems 



Even with the correctly chosen database migration strategy and the end-to-end data validation that precedes the legacy database migration procedure, testing a new database can produce unexpected results. This is why you will have to carefully revise the data again under different scenarios.

### API Development for Legacy Healthcare Software

Modern times call for up-to-date technological measures. Still, legacy software systems make up a huge part of existing platforms and solutions across industries for various reasons. Global healthcare is not an exception. This is quite unfortunate – the growing market with growing demands and expanding common practices cannot be hindered with legacy solutions for long.  



And if an established, reliable healthcare provider still runs legacy software of any sort – it is more than necessary to timely modernize and boost one’s internal software capacities for several reasons. Legacy software can include programs, transactions, jobs, and procedures that run within existing application systems. As a rule, these systems are based on obsolete technologies, which leads to the following challenges:




High cost of maintaining legacy systems;



Increased exposure to a data breach;



Fragmented systems with diverse data formats;



Poor opportunities for scaling and innovation.




Open APIs (Application Programming Interfaces) have proven their efficiency across industries since they provide easy access to information and capabilities. The medical sector, in particular, can benefit from open API for legacy healthcare applications, as they allow building the best solutions for every healthcare scenario. 



The Ultimate Use of API for Legacy Healthcare Software



API for a legacy healthcare system can address the existing issues and open the world of advanced technologies for healthcare institutions. Primarily, APIs help address some major concerns in this sector by giving patients total control over their electronic health records and boosting data exchange between health systems. Essentially, API for a legacy healthcare platform can do the following:




Enable cooperation between healthcare organizations and players from the other sectors;



Unleash the giant potential of collected and shared healthcare data and patient records;



Enhance the use of advanced technologies in healthcare, such as AI, proximity technologies, data visualization, and more.




Overall, APIs liberate applications and digital health organizations while helping health systems gain higher value from their EMRs.



APIs can vary by type, but generally, all of them work in the same way:











Specifically, when implemented by a qualified software modernization company, API solutions can provide the following advantages to a healthcare organization:




Performance flexibility;



Simple deployment;



Boosted user experience via high-performance applications and telehealth solutions;



Enterprise-grade scalability;



Reinforced data security;



Interoperability, which promotes digital health approaches and facilitates diagnosis setting;



Dramatically decreased overall costs;



Minimized enterprise-hindering risks.




Apart from creating a win-win situation for healthcare institutions and patients, data exchange and management with APIs can also benefit other medical system parties, which is illustrated in the scheme below:







What You Need to Know about API Development for Legacy Healthcare Applications



When implementing an API strategy, a hospital or any other healthcare facilities should consider the best practices of API development for legacy software. For instance, a legacy EHR might only allow such standards as HL7 V2, HL7 v3, and CDA., while a modern population health system only exchanges SOAP web services messages. This fact considerably complicates interoperability in the healthcare niche. So what can we do?  



Since API integration is considered as one of the key legacy system modernization approaches, organizations should focus on the specifics of this process for healthcare. Thus, follow these basics: 








Consider how exactly you can implement APIs to modernize legacy systems and applications. There are two distinct strategies in this regard:

Organizations can package existing legacy services in a way that makes them more consumable by businesses by either wrapping services with RESTful APIs or exposing access to constituent web service operations through APIs;



Organizations can develop miniservices or microservices by re-architecting the underlying application code and exposing functionality through APIs.






To make the proper choice, healthcare providers should consider the context and workflow of healthcare facilities that use existing health data-producing technologies. While making most of it, consult with a software modernization services provider on the proper approach.








Access dependencies in your existing monolithic systems. Long-living applications usually have lots of dependencies, which are huge enemies of distributed architectures. In contrast, a microservice-based architecture can combat the related issues. 




If you have a monolithic architecture with well-segmented domains, few dependencies, and an automated release process, you may not need migration to microservices. However, it’s more likely that you’ll have to break up messy monoliths into neat microservices. There are also other aspects to assess when determining the legacy. You should check all systems in place to reveal the existing and potential issues. Inspect all aspects of your technology, from code and architecture to visual impression, considering your business goals. 








Develop a detailed plan matching your modernization strategy. A plan typically starts with identifying issues and setting goals.

Figure out why you are going to build an API. Determine your target users and what data you are going to make accessible.



Outline the user functionality for your required API. In other words, what does your API need to do?



Understand the type of API you are building. Each API format has its specific features, and you should choose according to your tasks. Even if legacy systems aren’t supporting the FHIR standard yet, there are well-documented FHIR mappings for legacy interoperability standards such as HL7 v.2 and CCD. Learn more about how to comply with the new FHIR interoperability standards.



Keep in mind the long-term use. Your API should be standardized, extendable, and ready to serve your and clients’ needs as long as possible.











Conduct the legacy system integration with API simultaneously, test your system, and refactor the required components.









Select the proper data integration approach, and back up all your data. You should make sure that your data is secure and accessible. To prevent data losses, back up all your information. In this regard, it is crucial to make sure that archiving and moving data to new environments goes off smoothly. 









Document all the changes you make to keep track of the progress. Meticulous documentation helps work out efficient procedures for the future, avoid the same mistakes, and observe your progress step by step.




Legacy Healthcare System Modernization Risks to Consider



The challenges that derive from legacy modernization through API integration include the following:












Security concerns. 




APIs deal with protected health information and so must adhere to HIPAA Privacy and Security Rules as well as with other regulations. Health IT Security outlines the two key questions that healthcare organizations should ask in determining an appropriate level of encryption and when encryption is needed, as recommended in the HHS HIPAA Security Series. 




In order to prevent unauthorized access to ePHI (either by unauthorized persons or applications), analyze what data should be encrypted and decrypted?



What methods of decryption and encryption are necessary, reasonable, and appropriate in your context? This measure prevents unauthorized persons and applications from gaining access to sensitive health information.





Messy legacy code.




Legacy code that was initially created for the specific platform features should be treated with particular care. Even if some pieces of it may seem to need replacement, they should be thoroughly checked. 




API testing can be a challenge. 




In addition to the headache of coordinating tests among different companies and agencies, healthcare systems can have a complex data flow across multiple environments. Simply put, they may not be replicated in test environments. We recommend you check the system at every stage of the API development process.



How to test a legacy codebase without breaking anything? Learn here. Testing Legacy Codebase: What is, Common Problems and Best Practices 




Data standardization. 




Multiple data standards that were established years ago usually contradict the new regulatory rules. So, if your system was designed in those times, get ready to revise all the documentation. One way or another, your system must match modern requirements. 




Skills shortage.




The lack of qualified talents is a common issue of every legacy project. Less and less developers want to bother working with dead programming languages and supporting “smelly code”, especially in huge enterprise projects. 



In order to choose the right approach, mitigate potential risks, or bridge a skills gap in your project, it is always better to consult an expert. Ask all your questions on legacy application modernization that will help you build the proper API solution for an outdated healthcare platform.

### Consider These Things Before Legacy Application Re-architecting

There is always a time in a company’s life when change is inevitable to survive in the market. We’ve already outlined a bunch of software modernization strategies in our guide, but in this article, we will concentrate on the re-architecting approach. Re-architecting of outdated applications is the perfect choice for businesses willing to upgrade their app functionality and make their system extensible for future growth.  



What you will see in this guide is what legacy software re-architecting is, the benefits and drawbacks of this invasive approach, and useful tips for a successful migration.



What Is Legacy Software Re-architecting?



Legacy application re-architecting refers to redesigning the existing architecture with new advanced computing concepts. Using declarative models and parts of the original code, engineers can preserve a good deal of the business logic and avoid building a new application from scratch. In other words, you can migrate code-independent business processes to a new system while utilizing modern technologies. 



Re-architecting strives to improve performance, stability, and other non-functional aspects of the app. The process is lengthy and expensive; however, it can bring many benefits if done correctly. 



What Problems Software Re-architecting Solves



How can your legacy application benefit from re-architecting? Which problems will disappear after you re-architect your system to fit in the modern IT environment?



Elevated costs 



Businesses that operate with legacy software often suffer from increased costs caused by the inflexibility of the traditional IT infrastructure. A modern IT ecosystem allows for the scale-out elasticity that hardware-based infrastructure fails to provide. For example, cloud storage can save you a significant portion of the budget, which explains the ever-growing popularity of cloud platforms like Azure and AWS that offer serverless architecture.



And this is how much you overpay for the legacy software in your organization: The Cost of Maintaining Legacy Systems: How Much You Overpay 



Serverless architecture gives access to the pay-per-use pricing model that eliminates overspending on unused or duplicated services. At the same time, this structure ensures auto-scaling and relieves developers of the duty to constantly monitor the system, thus allowing them to concentrate on improving the system. 



Failures of monolithic architecture 



Legacy software solutions are often monolithic apps created as a large system with a single code base and are known for brutally failing after experiencing a minor issue. Unlike the microservice approach that provides fault tolerance with decoupled services, monolithic architecture is prone to jeopardizing the entire application. The microservice architecture ensures that other services continue functioning when one service fails, which prevents the app from a complete shutdown. 



Relying on a monolithic architecture is no more valid. Here's how service-oriented architecture can improve business processes Migrating a Legacy Application to a Service-Oriented Architecture (SOA) Guide 



Lack of scalability





Legacy systems are notorious for the lack of scalability that resurfaces when the company grows bigger. Small companies might not take this feature seriously at first, but once they expand and get closer to the sizes of Facebook or Amazon, the need for becoming scalable becomes apparent.  





When you re-architect legacy systems for the cloud, your applications or parts of them automatically scale up or down, depending on the demand. When you experience a sudden spike in traffic, your system will expand to meet the demand, while when the user traffic goes down, the application will shrink to reduce unnecessary costs.  





Inability to comply with all technical and business requirements



As mentioned before, re-architecting enables companies to preserve the business processes, functionalities, and differentiators. Re-architecting involves redeveloping the legacy application to suit a more advanced platform while keeping the business processing intact. 







In other words, you can modernize the system to enjoy the complete set of modern IT environment characteristics without the need to create new business logic. Moreover, you can even optimize business logic and data workflow while benefiting from more advanced architecture. This modernization approach enables companies to use the new technology paradigm to change their interactions with customers and transform the business.



3 Signs It’s Time to Re-architect the Legacy System



When does change become irrefutable? Let’s talk about the most important signs that show that it is definitely time to re-architect outdated software. 







#1 You are dependent on hardware that is expensive to maintain



Legacy software makes you dependent on high maintenance hardware with skyrocketing expenses and increasing vulnerabilities. A great example of such a system is the Department of Homeland Security in the United States that has 168 highly critical vulnerabilities that expose the department to significant security breaches. Besides, your legacy platform will not keep up with the newest technologies and innovations, you will end up overspending on costly maintenance and eventually may lose your competitive edge. 



#2 You have cloud compatibility issues 



Re-architecting code becomes an essential step when you start having problems with the integrations with cloud components. If you decide to migrate to the cloud and discover that your monolithic system is not compatible with the cloud, consider re-architecting. This method allows you to break down your stale app into functional components, also known as microservices, that can be individually adapted and moved to the cloud environment. 



#3 Your business outgrew the application



You may want to consider re-architecting software if your business requirements outgrew the application potential. For example, your business has acquired another firm or decided to build a custom solution without starting from zero. Basically, you have new tasks that your current system is unable to solve and thus require a dramatic update. In this case, rearchitecting your solution and making it more adaptable to the changes will allow you to gain scalability and keep up with changing requirements smoothly.



How Is Legacy Application Re-architecting Different from Other Modernization Approaches?



Re-architecting is not the only modernization strategy out there. Although modernization experts identify many types, we will focus on the most prominent ones: rehost, replatform, and re-architect. 







Rehosting or Lift and Shift



Rehosting is the simplest and least invasive modernization method and entails shifting the application to the new IT environment without making any changes to the code or architecture. 



The benefits of rehosting:




No effort as you simply move the app without making any changes. 



No disruptions to business processes.



No compliance and policy changes are required. 




The drawbacks of rehosting:




High rate of migration failures with rehosting.



In the absence of pre-migration changes to accommodate the new ecosystem, performance issues might occur.



Moving apps without working on the existing problems might result in bigger issues after the migration. 




Replatform



Replatforming goes a dash further and introduces some minor changes to the application to take advantage of the new IT paradigm. For example, you may change how the app interacts with your legacy database first to benefit from automation in the cloud environment. 



The benefits of replatforming:




No major changes are required, which makes this approach affordable. 



Apps can take advantage of scalability. 



Leveraging cloud features like storage services, infrastructure as code, etc.




The drawbacks of replatforming:




Hard to navigate and keep low-effort as scope tends to grow. 



Limited services, as specialized ones, require significant changes to the application. 




Re-architecting



Legacy system re-architecting requires an in-depth understanding of both the modern IT environment and the application. This approach is the most invasive of the three and takes the longest to complete. However, it is also the approach that gives you the ability to build custom solutions. Rearchitecting allows you to plan ahead and evaluate the load according to future needs, thus avoiding scalability issues. 



The benefits of re-architecting:




You can preserve business logic while redeveloping the app with more modern technology. 



The re-architected app will be built on the microservice architecture that allows for greater agility, innovation, and scalability. 




The drawbacks of re-architecting:




This approach is the most time-consuming type of migration.



You will need the best data engineers on your team or an experienced modernization vendor to see the migration through. 



The increased amount of time and human resources makes this approach quite expensive.

Possible Risks of Re-architecting a Legacy System



Incomplete or missing documentation



In most cases, companies decide to re-architect outdated applications that have been around for at least 10 to 15 years and are missing detailed documentation. Back then, there were no strong coding standards and practices that resulted in messy and undocumented code. Now, these codebases are hard to read, maintain, and streamline, which complicates the re-architecting process. Besides having difficulties with smooth system expansion, you will probably face a lack of engineers who developed these systems and know them well enough. If the documentation or essential parts of it are missing, teams are forced to begin projects with a black box full of business processes, technology, and other essential data. 



Solution: To organize this chaos, start documenting requirements and leave more time for planning and analyzing to establish an order.

Decrease in customer experience



Long-term customers get used to small details in your app, and even a tiny change in UI might lead to user disappointment as they have to relearn how to interact with your program. 



Solution: Make customers an integral part of the innovation process and take their opinions into account. 



Changes in UI&UX are vital to increase customer retention rates. Check all Risks and Approaches of Legacy Application UI and UX Modernization 



Team effort coordination



If you decide to re-architect code, you will still need to keep the old product afloat as well as work on the modernization. You will need to either split your team in half and assign one task or the other or have your entire team switch from one task to another. Both options are not very viable. 



Solution: First, analyze your human resources to establish how many employees could devote their time to maintaining and updating. If you discover the lack of personnel who can fill this gap, hire a reliable legacy modernization partner. Without a professional team, your re-architecting project is bound to drain your time and resources.



Tricks and Best Practices from ModLogix — Your Reliable Legacy System Modernization Partner



Here is a short list of the things to consider before starting the re-architecture process for an application: 



1. Invest into documentation



To avoid challenges of legacy system upgrading, proper documentation is the number one requirement for successful projects. If your documentation is poor, partial, outdated, and unstructured, start with writing application logic, current architecture, business logic, environment, planned upgrade actions, etc.  



To make this process more efficient, use an online tool such as Atlassian Confluence which will provide rich functionality for team collaboration. 



2. Try to keep the data layer untouched for as long as possible



Most of the projects have data storage (like SQL server) on the backend that’s outdated and usually requires refactoring as well. But if you can create new data models which connect to existing entities in the database, you will be able to run new and old versions side by side. This will make testing easier and will allow for a gradual transition. 



3. Plan your project deliveries in phases



It’s common that the rearchitecting process drags on with the companies barely seeing any changes or improvements in their software. So, in order to avoid any stakeholder or customer frustration, plan to deliver the new version in phases. Plus, you also can adjust the product on the go according to customer feedback.  



Optimally, a working version must be deployed at the end of each phase. For example: 



Phase #1 - Proof of concept: a phase where you test new approaches, validate the planned implementation. 



Phase #2 - Core functionality: migration of the most critical features. 



Phase #3 - Alpha testing as soon as all functionality fixes are finished. 



Phase #4 - Bug fixing, preparing for production. 



4. Do a prototype development



Since app re-architecting implies the use of new tools and technologies, including new programming languages, frameworks, and platforms, make sure your team has enough experience with the new toolset. Otherwise, incorrect assumptions and estimates can possibly be made that lead to wasting the set budget. 



If your organization lacks technical expertise, consult with qualified vendors to validate your estimates. 



5. Retire unnecessary components



Almost all old software products have had now-obsolete functionality added to the product over the years. That’s why when rebuilding legacy software, it’s crucial to review the current functionality, documentation, business goals and retire the parts that are no longer important or not widely used.  



It is an excellent opportunity to create an optimized system.  



6. Add new functionality 



If you have any product improvements in mind, the re-architecting phase is usually the best time to consider planning and implementing the new functionality. Conduct deep research before adding any features; they should encourage business growth and ensure high ROI in the end.

### Experts Answer 10 Common Questions on How to Migrate from AngularJS

The upcoming AngularJS end of life leaves no choice for organizations but to think over migrating to more reliable frameworks. But the closer the depreciation date is, the more questions and concerns around the migration arise. Some business owners are terrified by the possibility of needing to rewrite the app, while the rest of them just got used to good old AngularJS code and structure.   



However, December 2021 is the AngularJS end-of-life date. After this time, the apps will be exposed to security vulnerabilities that are critical for businesses and users. To help companies get into the migration path, we asked industry experts about AngularJS and its peculiarities. 



Angular 14 is available now! Learn the features and updates. Angular 14 New Features and Benefits for Business and Developers 



In this AngularJS migration guide, we gathered valuable insights from developers and thought leaders who already abandoned AngularJS in favor of modern tools. Where should you start the upgrade? What processes must you automate? Read these 10 questions and answers that dispel your doubts.



Is rewriting everything from scratch the only option to upgrade from AngularJS?



This burning question baffles organizations that own AngularJS apps around the world. Rewrite or resort to other approaches? Where’s the "the golden mean"?



Previously, we uncovered 3 typical approaches to move from AngularJS to Angular: rewrite, hybrid with ngUpgrade, and Angular Elements. In short, a hybrid with ngUpgrade option implies running both frameworks simultaneously. Angular Elements package, in turn, allows automatic transforming Angular elements into custom ones. Both approaches facilitate migration but, in the meantime, they aren’t suitable for most of the legacy solutions.  



9 out of 11 experts said that the only way to update in AngularJS is to create the whole app from scratch in some new framework or resort to a gradual upgrade. The thing is, most apps inherited tangled architecture with plenty of controllers used instead of components. Most likely, you’ll spend more effort on streamlining the existing codebase.  











Our expertise also shows that it’s better to redesign a system because of fundamental differences in the syntax and structure of modern tools. 



Pros of rewriting: 




opportunity to resolve performance and inconsistent code issues;



add and expand the functionality of existing solutions;



revise the business process and its efficiency;



save costs on future maintenance and recruitment.




Cons of rewriting: 




lengthy and expensive procedure;



overall complexity, incl data loss, errors, etc. 




The verdict is quite clear – the successful migration involves rewriting almost everything from scratch. However, despite the complexity, the rewriting efforts will pay off shortly.



Is there any difference in frameworks to migrate to? What to choose: Angular, Vue, or React?



The reasonable question before the migration from AngularJS would be the new framework. Today, the technology market has a wide choice of front-end tools headed by 3 leaders: Angular, React, and Vue.JS. Based on the Stack Overflow and GitHub surveys, each tool generates an equal amount of interest from developers. But what do they offer in practice? 







Angular



Angular, the obvious successor of AngularJS, was released in 2009 by the Angular Team at Google. Despite the common roots, these frameworks are utterly different. Angular uses a more consistent language (TypeScript) and has a component-based architecture that is better structured. 



When it comes to migration from AngularJS to Angular, you can automate some of the processes, but basically, everything must be redesigned. Angular is widely used for large-scale enterprise projects because of the full-fledged package of solutions such as navigation features, advanced refactoring, etc. 



Legacy code is a minefield. Learn how to optimize your code base with this guide. Legacy Code Refactoring: Tips, Steps, and Best Practices 



At ModLogix, we’ve worked on a couple of successful AngularJS to Angular migration projects. We’ve collected the best approaches, hacks, and tips in our ultimate AngularJS to Angular migration guide. Also, you can explore our unique AngularJS upgrading approach in detail. 



React



React, developed by Facebook, has gained a lot of popularity in recent years. It has broad community support, solid feature set, documentation and generally has little to no difference from Angular or Vue. React is equally used for small, medium, and enterprise-level applications which makes it a decent choice for any project. 



If everything is so crystal clear, are there any issues when migrating from AngularJS to React? The scheme is almost identical to Angular, as you must fully recreate the app. Developers rewrite the legacy components in React using top-down or bottom-up approaches. 



Vue



Vue is another JavaScript library driven entirely by the open-source community. Unlike its competitors, Vue offers highly customizable features to build any sort of app. Developers appreciate it for its simplicity and flexibility, even though such freedom can result in poor coding. 



If you decide to migrate AngularJS to Vue.js, you won’t stand alone on this path. Their official community offers extensive support backed up by helpful examples in Stack Overflow and GitHub repositories. 



To sum up, there is no distinct difference in the frameworks you’ll choose to replace AngularJS. The things you should consider are your business and migration goals and current tech stack. After all, you can always consult with experienced vendors to find the most natural fit for your case.

Will your AngularJS app suffer from security vulnerabilities after 2021?



According to our experts, security vulnerabilities in legacy AngularJS code are the most solid reason for migration. Official announcements state that security patches and regular updates won’t be distributed anymore, which means possible security loopholes in your app. 



Curiously, AngularJS has always been a stable framework that’s proven by statistics – it hasn’t experienced any vulnerabilities in 2021. But what might happen without constant improvements and community activity?



stack.watch statistics








The app becomes incompatible with dependent components such as jQuery. Consequently, with each jQuery update, the outdated AngularJS system may crash or work improperly.  









Browser compatibility becomes questionable as well. 









You need to address unforeseen issues that can arise in AngularJS by yourself.




What can you leave as is during the upgrading?



Upgrading the AngularJS app as a part of the migration process means doing everything from scratch. But the part you must preserve is the business rules that describe relationships between objects. Simply put, business logic must be strictly mirrored in the target system. Such a strategy gives you a full understanding of how the new system will work.     




"Except for some code workflow (would not say even code), rest has to be completely rewritten. Why I said code workflow due to the change of programming from JS to TS, and it has to be at an advanced level where you have to put code in a well-structured manner to make it perfect."
Mukul J., Software Engineering Manager at Intel




"Maybe should be considered save only logical and structural business rules, all other written code put in trash and re-write from 0 point."
Daniel Krug, Software Engineer 



Just to be clear, the upgrading process breaks down into cohesive steps:



1. Planning the migration (streamline AngularJS code to follow guidelines, gather the documentation, refactor code pieces, etc.)



2. Choosing a migration approach: top-down (upgrading separate features or screens) or bottom-up approach (working with individual components)



3. Supporting the existing version and creating the new one in parallel



4. Running auto-tests



5. Setting up Continuous Integration/Continuous Delivery (СI/CD) for the sake of productivity











Why migrate from AngularJS to Angular?



Numerous companies still use AngularJS to build web interfaces, and an impressive number of developers openly dislike it. According to the 2021 Stack Overflow survey, 76.82% of developers are dreaded by AngularJS. 



Critical flaws of AngularJS that must be considered:




AngularJS has a two-way data-bind feature that leads to delays and bottlenecks during development. As a result, poor performance and maintainability. In further Angular versions, the community improved this model a lot to avoid the app’s overload. It allowed companies to enhance overall app performance and operation speed along the way. 









AngularJS can’t provide the feature set to build accessible and user-friendly websites. Conversely, modern tools use Material design templates, introduced by the Google development team, to create up-to-date design solutions.  





"One of the reasons why organizations must move from AngularJS to Angular to satisfy new age demands is because of the enhanced user interface provided by material design."
Dusan Stana, Founder & CEO of VSS Monitoring 




Much has been said and written about the AngularJS architecture, and Model View Controller (MVC) pattern. Compared to Angular component-based architecture, MVC complicates the software development process and stirs up the development time.




What are the compelling arguments for companies to stay with AngularJS? 



The Angular team confirms that “all AngularJS applications that work now will continue to work in the future.” So, there’s every hope of continuing to use a familiar system for a lifetime, isn’t it? 



Partially, it’s true, and there are several conditions that may justify the use of the AngularJS app for business purposes after 2021: 




The system will be retired shortly.



The system must be maintained only. It involves fixing critical bugs and serious flaws but not developing new features or improving software state on a large scale. 



AngularJS features are vital for the current app. For example, the basic functionality is fully dependent on third-party tools that aren’t available in Angular (WebStorm and IDE).  



You are not using AngularJS as a Single-page application (SPA).




Summarizing these points, experts agree on one argument – if the app is going to be replaced anyway and you are ready to take involved risks, keep staying on the final AngularJS version and rely on package managers. 



What are the best practices for upgrading AngularJS to Angular?



As we mentioned previously, loads of companies and developers are reluctant to start the modernization of outdated AngularJS apps. Despite the challenges, there’s also good news - migration from AngularJS to Angular is already well-defined.  



The Angular community provides official documentation on how to migrate from AngularJS to Angular. Also, their GitHub forum is plastered with useful tips and insights on migration.  



Our team and industry experts created our own roadmap for migration based on real-life experience. 



Tip 1. Invent the apps that should be migrated. By knowing the true state of the system, it would be easier to estimate the process accurately and avoid extra expenses.



Tip 2. Decide on the strategy you’ll follow: top-down or bottom-up. You may focus on upgrading concrete elements or components as a whole; the one thing is it must comply with your business rules. 



Tip 3. Clean the current codebase in conformance with the AngularJS Style Guide. The more structured the app is, the easier it will be to migrate it via auxiliary tools. 



Tip 4. Consider a hybrid model to handle routing. Angular has an updated routing feature that does not work for AngularJS. When migrating big enterprise systems, move one route at a time and run two instances of the app simultaneously.



Tip 5. Get rid of $rootScope and $compile that are not available in Angular. The fewer dependencies on $scope, the better. They can be hidden in such functions as $compileProvider.preAssignBindingsEnabled(true), $element.replaceWith() and services that are used to store currently global variables.



  VIEW CASE STUDY   







Are there any migration efforts to be automated?



In a nutshell, there are not many tasks you can automate throughout the AngularJS migration. With a ngUpgrade package from the Angular community, companies can facilitate some processes in a certain context. It’s also possible to load the TypeScript compiler to speed up utilizing TypeScript on top of JavaScript code (e.g., Webpack).  



But one way or another, developers must iron out all errors or other inconsistencies that come to light. 



How to overcome migration risks? 



Software modernization projects always involve risks as the legacy systems are often clunky. One false move and they break down when you least expect it. 



What issues may pop up during the migration that you must be aware of before jumpstarting the development? 



1) Don’t use templates created by combining user input. 







2) Don’t exploit native DOM APIs to interact with HTML elements. 







3) Avoid Angular template engines, especially when rendering server-side templates.







4) Remove all outdated concepts that don’t fit Angular (previously mentioned $rootScope and $compile, etc.).







5) Ensure that only valid changes are sent through the dev chain.

Of course, in spite of these risks, other unforeseen events may occur, like a lack of developer competency with AngularJS and Angular. However, forewarned is forearmed, which means you are unlikely to hit these problems in your case.



What should you do before migrating from AngularJS?



As we said previously, planning is of the utmost important stage. When setting AngularJS to Angular migration plan, you should be clear with your objectives, budget constraints, the team involved, and a risk management strategy. As a basis, you should categorize the risks according to their impact: business, organizational, and technical ones. And then divide them into severity levels. 




“I planned ahead of the migration and chose a strategy to follow. While on migration, I revisited and reevaluated the chosen strategy. One tip is first to map out any cross-app dependencies to make sure you get services working.”  
Katherine, the founder of Spyic 



Another thing you should think of is your development team. If you decide to pitch upon a hybrid strategy, meaning support two systems, organize two separate divisions. One must maintain service production while the other upgrade to the new framework. Our experts also point out the necessity of AngularJS expertise. AngularJS, while not being an ancient framework, requires advanced knowledge to accomplish the migration successfully.




“Lack of training and needed skills from the employees is one of the main barriers to migration. Companies’ staff are lagging on the knowledge and understanding to operate new infrastructure. Managers fear the risks involved, like data loss which could lead to financial and reputation burdens.” 
Katherine, the founder of Spyic 



Conclusion



We hope that this Q&A post didn’t leave any questions on AngularJS status and migration routes. In all other cases, we’ve got you covered. Stay with a depreciated framework or move to a more stable alternative, is henceforth the matter of your business priorities and security goals.

### Microservices Architecture Advantages and Disadvantages, Risks, and 5 Use Cases

In recent years, many companies have been upgrading their software to a microservice architecture. According to the 2020 O'Reilly survey, about 28% of respondents mentioned that their companies use this approach for three years or more, and more than 60% use it for at least one year. This means that it’s the perfect time for you to implement cloud microservices architecture and learn about the advantages and disadvantages of microservices.



If you're looking for the right team of experts to migrate your application to the updated platform, contact us to discuss the prospects for developing your software.



What are Microservices? 



In a nutshell, a microservices architecture is a collection of independent modules that run every process as a separate service. Each has its scope, database, and operational logic, but they communicate via APIs. Basically, they can be treated as independent software products as opposed to the monolithic structure principles.



Microservice is a special variety of software architecture distributed by separate domains. It’s of narrow-focused nature, meaning that each microservice handles a specific task, uses autonomous data storage, and has its own (independent of any external modules) means of connecting with the storage. Similarly to web services, one can effortlessly combine microservices in Java, C#, Python, and even in mobile software development languages.







Why Enterprises Choose to Use Microservices



Why choose microservices? Microservice software architecture is based on many interconnected but independently functioning software modules that can be easily replaced, removed, and reused in other projects. Each microservice has a specific, narrowly targeted task. At the same time, even if this module accesses the DBMS (Database Management System) or server, it does it autonomously, without resorting to the help of third-party modules.



Service-oriented architecture replaces legacy approaches to building software. Migrating a Legacy Application to a Service-Oriented Architecture (SOA) Guide 



Essentially, you can use small ‘bricks,’ each of which has a unique purpose, to construct a bigger ‘building’ — the final software product. For many major types of software out there this is simply short of a perfect solution.  However, opinions in the industry still differ. According to the mass survey, 55% of respondents state that the adoption of microservices has brought them either next to exactly desired or exactly desired results. That leaves us about a half of the respondents’ audience that has slightly or completely different thoughts. Let’s explore what may affect the mass preference positively or vice versa.



Microservices Pros and Cons



The following microservices pros and cons can help better understand whether there is a need to implement it in an existing software solution.











According to all microservices advantages and disadvantages above, we can argue that this is quite a performance-boosting solution for large-scale projects aimed at automating deployment, as well as the constant growth in the number of features and users.

Role of Microservices in Software Modernization



Taking into account all the benefits of microservices, from the point of view of software modernization into a microservices architecture, you get to:




increase the stability of regularly updated applications: they continue to function even if a single module fails;









eliminate the need to use previously used technologies: when you modernize your current app version and build new functional modules, you can use any tech stack and choose modern and easy-to-use programming language;









achieve higher maintainability and cut recruitment costs: microservice solutions are ultimately simpler to maintain, and you can gather development teams to work on them much faster due to very basic programming requirements.












As for the indisputable advantages of microservices for business, they are as follows:




higher employee productivity: a segmented workflow saves specialists from getting tangled in massive instances of code. Therefore, less routine is required to reach the results, which certainly motivates workers to complete more tasks in shorter terms;









increased scalability: instead of the only horizontal or only vertical scaling possible for monoliths (with a forced hardware upgrade), companies also get the opportunity to implement different scaling approaches simultaneously, scale up to handle growing loads at any time, as well as rapidly implement features and system innovations (boosting revenue numbers, competitive edge, and other in the process);









organizational alignment: CI/CD techniques (they are often used during microservices implementation) allow companies to shorten the time to market without losing non-functional requirements (performance, maintainability, scalability, reliability, operational factors, etc.), as well as integrate changes as quickly as possible into the working version of the code;









optimized business functionality: companies can upgrade the functionality almost endlessly by connecting new and deactivating old, unnecessary blocks.




Microservices Risks of Implementation and What They Mean for Your Business



With the real disadvantages of microservices, there are plenty of scenarios where they are in the utmost need. Before we list the risks associated with the microservices' implementation, we would like you to know that you can avoid and minimize them by:




your awareness of all microservices disadvantages;



risk management;



cooperation with a qualified team or partnership with a professional vendor.




Microservices Implementation Risks



Here are top-3 microservices implementation risks identified by our developers and ways to handle them properly:




Risks of a company being underprepared to move to a new architecture. Unfortunately, not every company is ready for the transition to a new architecture. Therefore, before taking this radical step, you have to assess if the system is ready for migrations (since in a monolithic architecture all components are closely related, this can complicate the development of a new architecture);









Underestimation of the process complexity. Companies often underestimate the complexity of microservices implementation because they focus on simpler maintainability as a major benefit. However, in reality, during migration, other problems may arise, for example, related to performance or incompatibility of components. Also, companies may face some security risks when moving monolithic apps to microservices; 









Unclear goals and poor budget planning. Sometimes, companies set unclear goals and find themselves in a situation when their expectations are not met. To avoid such scenarios, learn the advantages and use cases of microservices as applied to your sphere and tech resources. 




To avoid all these microservices risks, hire our experienced team. We will apply our best practices to save you money and time.

5 Use Cases of Microservices



Why use microservices? To answer this question, let’s find out in which microservices use cases this type of architecture can be a holy grail.



Outdated apps 





The first use case of microservices is updating old applications with the preliminary refactoring of the code, using new technologies, programming languages, and third-party tools. This is necessary when existing software solutions no longer meet new business needs and require a move to the cloud. 





In addition, such an architecture can provide autonomous operation of services and modules, allowing them to be reused in different systems (for example, it can be authorization services, search services, etc.). 





Big data apps



Systems that use big data with smart algorithms are ideal for the transition to new architecture due to minimizing the number of dependencies and reducing the time for processing operations. This is why the vast majority of machine learning and artificial intelligence solutions are based on this architecture.



Real-time processing solutions



Streaming solutions, as well as instant data processing solutions (transactions, geolocation, etc.), also use microservices to ensure that operations are performed at an appropriate speed.



High-traffic websites



Solutions with a high tendency to scale (for example, news portals and social networks) need to improve on-demand performance and fast content delivery. Microservices are capable of meeting all of these needs.



Solutions made for big workloads



To quickly process numerous simultaneous user requests, it makes sense to migrate to the cloud. In turn, the updated architecture assumes placing the system on several domains at once, which intelligently distributes the load on its server side.

### Managing Legacy Data in Healthcare: Migration and Archiving Guide

Being the dynamically developing field it is, the healthcare sector has accumulated so many assets, technologies, systems, physical and virtual environments, etc. over the years, that now it practically overflows with legacy healthcare software. This includes legacy data archives (storing patient histories, individual records, internal data, etc.) that need more reliable storing means and equipment and systems that were introduced 10-15 years ago and now require proper support and maintenance. 



This is where timely data migration in healthcare facilities and advancement to a new, smoother, and faster running EHR is essential. The underlying processes of archiving and moving data to new environments are usually carried out by properly qualified service providers, either with special tools and platforms. But you still need to know the specifics not to get lost in all the nuances. 



Let’s go through the ins and outs of the process — why exactly it should be done, how it is done, and how you can actually start to manage healthcare software data more efficiently.



Defining Data Migration in Healthcare



Data migration as part of a legacy system upgrade or modernization is the process of transferring data assets from a legacy system to a new hospital operating system environment. This is done in order to implement a major system update and smooth out the overall performance in line with the modern requirements. Considering how much healthcare application data is accumulated and stored in medical facilities worldwide, this aspect becomes more and more relevant with each passing day.











This is also backed by the huge importance of the patient data held in legacy database solutions — the ultimate data processing safety and failproof operation are crucial so as not to undermine or lose personal details, medical records, etc.



As much as the process is crucial, it has its sides of the coin. Namely, you get several benefits while migrating the data, but you also have to watch out for related risks and pitfalls. Let’s take a look.



Healthcare data migration benefits



Higher productivity. Staff employees are encouraged to work with data in intuitive, automated conditions, eventually smoothing out the overall workflow and getting to handle more work faster and with less effort.







Higher reliability. Replacing legacy systems in healthcare means staying in tune with all the reliability-boosting benefits new advanced security protocols and software management methods bring to the table. 







Faster overall performance. The newer and more up-to-date your healthcare software systems are, the faster performance they will show — it is as simple as that. 







Cut costs. The cost of maintaining legacy systems can be unreasonably high, as you may have to deal with software that ceased receiving updates and getting support from both creators and third-party vendors a long time ago.







More potential for innovation. Modern healthcare IT systems open vast horizons for further expansion into advanced infrastructures powered by powerful technologies such as Big Data and AI.







Higher customer satisfaction rates. All the above benefits can be summarized into the excellent ability to carry out and deliver all sorts of healthcare services faster and more effectively, helping you satisfy the demands of your customers all around.











Healthcare data migration issues



Storing and accessing data optimally in healthcare infrastructure. Many companies still consider data migration and required system upgrade an unnecessary one-time event. This isn’t true, as the data will continue to accumulate, and traffic management opportunities will be needed to timely expand further if you are operating long-term.  



On top of that, adopting a new healthcare data storage solution, you must abandon old yet closely familiar practices and adjust to the updated conditions, which may take time and spawn certain complications among the staff of workers (implementing the UI of a centralized portal should be an efficient solution here).  







Constant data accumulation. Be it a legacy operating system or a new one, data will continue to grow and occupy more space, and you need efficient means of sorting this out. (The most optimal means of storing and processing endlessly accumulated data may be resorting to cloud solutions and backing everything up with data archiving. This is akin to a daily routine.)







Dynamically changing data. All stored patient entries must be updated, corrected, and expanded in real-time, which calls for a well-thought-out, seamless frontend that won’t require too much effort from the staff that got used to old systems.







Misunderstanding data specifics. Healthcare and clinical data can come from numerous applications in various formats, quality, and encryption complexity. That’s why the thorough definition and distribution of data across proper fields of use must be elaborated to manage migrated clinical data in new EHRs smoothly and efficiently.

Legacy Data Archiving — What’s it All About?



Healthcare facilities of all sorts all over the world generate astoundingly immense amounts of data every single day. And most of it has to be stored for an indefinite time according to legislation. Legacy data archiving allows storing the data in a cost-effective manner. At the same time, specialists and managers get to access all the stored data any time they need, while they are also saving tons of hardware space through data archiving.



Alternatively to the path of the full-on data migration, archiving platforms help you simply archive all the data that’s not in active demand at the moment and access it only when there is a direct need. In the meantime, data archiving is also a substantial part of the full modernization of legacy data systems in healthcare. Let’s learn more about the process.



Healthcare data archiving advantages



Significant budget savings. You can forget about the data-focused expenses of managing legacy data systems in the healthcare facility and many unexpected costs; employing a data archiving solution, you only need to cover operational fees, which are often one-time.







Better standards compliance. Achieving compliance with HIPAA and other regulations may as well be the main goal of implementing data archiving (we explain more on this below).







Avoiding conversion fees. Moving massive amounts of data from legacy healthcare systems to new solutions can be unreasonably expensive. In contrast, you can save on conversion fees if you archive the data you don’t require regularly.







Productivity boost. Similarly to full-on data migration, a convenient interactive data archive that runs fast and smoothly streamlines the overall performance of the medical establishment’s staff, while legacy archive data management is a breeze.







More convenient access and higher data availability. A good data archive is an immense database of records that you can access and pull out what you need when you need it without any issues.



Healthcare data archiving risks



Loss of data or damaged data assets in the process. This may happen to the best of us (the archiving process is pretty complex and cumbersome). Still, everything should work out fine if you have true professionals handling the archiving and avoiding common healthcare data migration problems.







The other side of compliance. The compliance with regulations is listed as the benefit up above; however, this can also be risky if you fail to fulfill all legal requirements properly in the process of archiving, which, again, rests on the shoulders of technical specialists.







Unreliable provider. Ultimately, the proper expertise of the migration/archiving services vendor should prevent risks and mistakes while, sadly, there are still many underqualified providers that simply don’t have what it takes when it comes to seamlessly modernizing a legacy healthcare application. 



Archiving or Migrating — What to Focus on in Your Case?



Both approaches are quite similar in nature and complete each other. But there are some core differences. Simply put, full-on data migration is a more complex and resource-consuming process, while archiving is a stage of the process that’s more about backing up and saving both storage and data management efforts. 



In particular, data archiving is commonly applied as a legislation-optimizing measure. In terms of the data migration strategy targeted at achieving particular business goals, data archiving is a necessary step in making long-term data retention completely legal. It helps better establish all-around compliance with global healthcare regulations by reducing data loss risks while keeping all medical records in order and easily accessible.







 VIEW CASE STUDY  







Hospitals, medical centers, etc. also often have to update their means of healthcare systems data management when a medical establishment is undergoing a:



merger with another facility or full-on acquisition of a business;software infrastructure replacement;relocation or shut down of an establishment.



Archiving may also simply take place as part of data migration, where the data is archived while all the technical stuff is implemented and the new system is being prepared.



Moving healthcare data completely is more about the complete revitalization of the system or platform switch — when the hospital or medical center finds a newer, higher-performance system and decides to advance on to it, staying in tune with the times. 











However, data archiving isn’t always a necessary task here, while it can also be implemented separately when a medical establishment already has a running up-to-date data management system but lacks a virtual archive. Different legacy system modernization approaches may fit you according to your business specifics and migration goals.

### 20 Top Tips for a Smooth Cloud Transition

Cloud technologies attract more and more attention with every passing year, and moving to the cloud has become a common trend for modern enterprises and startups. Some people come to the decision naturally, in the process of continuous growth and development. Others are forced into it: the least-evil choice to improve on legacy systems.  



The older and the bigger a system is, the more unsolved and undiscovered problems it has. Such systems are difficult to maintain and impossible to scale or modify. These kinds of legacy software often goes against current standards, forces critical failures, and contains security and performance issues. 



To combat these problems and bring business to a new level, companies need to find better software solutions. More and more often, they decide in favor of moving to a cloud environment and delegating environment support and management to third-party organizations — the cloud service providers or vendors.  



Businesses may choose to make this move for a variety of reasons, and the benefits include increased productivity, scalability, and flexibility. However, like most things, cloud software has its risks. Certain roadblocks can emerge on the way to the cloud, and difficulties can arise, including issues relating to:  




security and data privacy; 



hidden and deferred expenses;  



dependency on a provider. 




Transitioning to the cloud is a serious upgrade that requires clarifying details, refining controversial points, and highlighting possible pitfalls.  



If your business has weighed all the pros and cons and decided to join the cloud community, you may still have the following questions:  




How do we prepare for the transition?  



What do we need to pay attention to?  



How can we soften the blow in case of possible issues?  




As with any other technology, cloud computing is just a tool; it can’t be good or bad by itself. The benefits you get from moving to the cloud depend on how carefully and thoughtfully you implement the migration process.  



In order to avoid drowning in the wide variety of cloud service providers and solutions available, businesses need a kind of a road map for the cloud transition process. So here at ModLogix, we have prepared a list of 20 cloud migration tips to make your transition to the cloud as smooth as possible. We hope this list will guide you through all the stages of cloud migration, from preparation to maintenance and support.   



First, to avoid getting lost in all these cloud migration hints and tips, let’s separate out the three phases of cloud migration:  




pre-migration or preparation;  



the migration itself; 



post-migration or maintenance.




10 Pre-migration Tips for Cloud Migration



The better you prepare for the cloud migration process, the better the chance that you’ll perform it smoothly and predictably.  



Keep in mind that there are two parties involved in the cloud transition process: your company and a cloud service provider. So we’ve provided tips that apply to your company as well as tips that you should keep in mind when dealing with a service provider.  







Your company  



Before diving into the cloud migration adventure, examine the current health and composition of your system, especially if it’s a legacy application.  



1. Evaluate the existing system  





Before considering migrating to the cloud, think of your business processes and specifics. Do you need cloud migration services for your organization? One way or another, migration poses some risks that could outweigh the advantages; not every business is ready to move to the cloud.  





Thoroughly revise all the components and interactions in your system, including architecture, databases, code, servers, storage, applications, infrastructure, integrations, third-party tools, sensitive data, legacy code, and unresolved bugs.

2. Clean up and reconfigure  



Next, clean up and reconfigure your applications to make sure you don’t migrate legacy errors. Not all data is important for your current processes; decide which data to move and which to leave.  



3. Prepare team and resources  



Analyze the expertise of your team members to ensure you have enough personnel resources to perform the migration process. Check to see whether those specialists who managed your on-premises system can work within the cloud infrastructure. Perhaps, you’ll need to invest in education and training to introduce a cloud-oriented culture to your company.  



Otherwise, if you have no internal team, or you don’t want to do the migration on your own, refer to third-party professionals who know legacy system migration inside and out.  



4. Know the most up-to-date regulatory policies  



Depending on where you’re located and where you do business, you may follow  GDPR,  HIPAA, or other policies. Constantly track the changes in cloud security standards.  



5. Have a migration plan  



Investigate existing migration strategies to choose the most appropriate one. Consider the basic Rs by Gartner:  




Rehost  



Refactor  



Revise  



Rebuild  



Replace  




Forbes gives an alternative list:  




Rehost  



Replatform  



Refactor (what is legacy code refactoring? Read the article!)  



Repurchase  



Retain  



Remove  




Or check out our cloud migration guide for CTOs.  



Make certain you have a rollback plan; it will be your plan B in case you abandon the cloud transition and decide to go back to the initial system configuration.  



What else you should know before cloud migration. Ask these 10 Critical Questions About Migration to the Cloud 



Think ahead, keeping in mind scalability, and future extension.  



The provider  



The ideal cloud migration provider takes care of most of the migration-related issues, starting from a full assessment of the current system and going all the way up to monitoring the after-migration KPIs (key performance indicators).  



It’s crucial for your business to have a proper provider with a suitable set of technologies and services corresponding to your needs. So, when choosing a provider, use the following tips.  



1. Consider the security level provided  



When you agree on the cloud deployment model, check the data protection policy the provider relies on. You want the provider to have two-factor authentication and to avoid account sharing.  



2. Consider risk assessment  



Check how the vendor assesses risk: legal protection, ownership issues, untrustworthy machine instances, and human errors.  



3. Separate responsibility areas  



Clarify the scope of responsibilities of each side to avoid future conflicts. The level of your interaction with the provider and your responsibility areas depend on the cloud service you selected. There are three general models for applying cloud computing: IaaS, PaaS, and SaaS. Choose the one that fits you most.  



4. Agree on performance metrics  



Formulate a set of criteria to evaluate the migration process and to compare the before/after results.  



5. Consider the cloud service provider  



Choosing a qualified software provider is a quandary for plenty of organizations. The provider must be experienced and reliable, and provide a high level of support. In order to meet these requirements, we came up with a list of questions to help you select a legacy modernization vendor.    



Even if you’re entirely relying on the cloud migration provider, don’t hesitate to ask what services and technologies are being used. Ensure that the cloud service is properly selected and fits your business needs. Consider the geolocation and physical security of the proposed data centers, as long distances can cause downtimes. Keep in mind that a diversity of laws can cause data security issues.  



5 Practical Tips for Moving to a Cloud Environment  



Though in most cases a cloud provider takes care of all the migration steps, it’s good practice to have an idea of what exactly is going to happen. Pay attention to the following tips for moving to the cloud to ensure a smooth and successful cloud transition.  



1. Set up the environment  



Set up the working development environment. Ensure that all components and services are compatible with the new environment, including the third-party services used.  



If possible, run services in parallel for some time. Properly clean up your old data storage.  



When one of our clients decided to migrate his Webforms system to Microsoft Azure, we carefully prepare a cloud environment before migration, as well as rewrite some app parts. Read the full case study on how we dealt with a complex migration project. 



In addition, we created the Azure migrate step by step guide to walk you through the steps of a successful migration.



2. Go step by step  



Migrate your services one by one. Choose one of the following methods based on your priorities:  




Move less critical items first to see if it works properly, OR  



Move the most important items first to speed up the process.  












Request proof of concept from the migration vendor and use trial migration if available.  



If you’re migrating to the cloud for the first time, use one provider to get experience. In future migrations, feel free to use multiple cloud providers if needed.  



In case of error or failure, use a rollback option to move to a previous step. If any errors occur, correct them as fast as possible.  



3. Use cloud-native processes  





Try to use cloud-native solutions where possible. Implement collaborative DevOps practices and close team communication to speed up software releases. Be ready for frequent code changes and dynamic usage of the infrastructure.  





In contrast to the traditional outdated monolithic application approach, get used to microservices. Try to break the applications into small, independent components and manage them separately. This allows you to scale individual parts, rather than the whole system at once.  





4. Perform continuous monitoring and testing  



Consider user feedback and user experience. Track system performance. Monitor KPIs and system security.

5. Keep in touch with the team  



Provide ongoing messaging and training to keep your support team up to date.  



5 After-migration Tips for Migrating to the Cloud  



The cloud environment is a long-lasting relationship. Once you’ve joined, you’ll have to constantly monitor and maintain the system. You have two options here: 




Teach your own team to monitor and maintain the system, if it fits your company business strategy and if the budget allows.  



Cooperate with the cloud vendor for support and further modifications.  




In any case, for smooth system operation, the following activities need to be performed regularly.  



1. Test and monitor the system  



Test basic features as well as critical points, including security, performance, and system health. Monitor system performance and KPIs. Correct performance metrics according to business objectives.  



2. Control system security  



Track sensitive data management. Keep an appropriate authorization and authentication security level. Track data management and storage security.  



3. Optimize the cloud environment  



Constantly upgrade the environment according to changes in regulatory policies and global technologies.  











4. Adapt resources  



Adapt your resources to avoid downtimes and underutilization; increase or decrease resources if needed.  



Use scaling, scheduling, reserved channels, and cold storages to optimize resource distribution across platforms.  



Learn from others, then implement best practices on your projects. 3 Legacy Software Modernization Case Studies and 12 Lessons We’ve Learned 



5. Train and inform the team

### Why You Shouldn't Convert Your Visual Basic App with Automation Tools

If we had a Visual Basic app to upgrade, we'd never use automation tools. Now, you might be thinking that's a pretty bold claim! Let's roll back in history to provide you with an explanation.     



Back in 1991, when Visual Basic 1.0 was released by Microsoft, it became popular among enterprises that wanted to build in-house applications. Over time, Visual Basic attracted a large community of developers who loved it as a friendly environment for beginners. In a nutshell, Visual Basic showed us what programming could do.   



Now there are thousands of VB apps scattered throughout the world filled with spaghetti code. Why is this? Because newcomers weren't skilled enough to follow coherent development practices when they were developing systems with Visual Basic. This leaves little hope that automation tools can convert this code to the new platform properly. 



Or can they? Let's find out together.







Spagetti code is technology jargon that refers to code that is written without a coherent structure and rules.



What Is Happening with Visual Basic in 2021: To Migrate or Not to Migrate?



Microsoft no longer supports Visual Basic — its last version was designated as legacy in 2008 — though it does still provide the community with applicable documentation. Many users are still using WinForms to build business applications in Windows, and a few are building websites using ASP.NET Web Forms.    



However, with new technologies on the horizon, Visual Basic has become an outsider in the industry; it doesn’t quite fit in. That's why Microsoft rolled out a VB and C# coevolution strategy to unify the .NET ecosystem and facilitate the transition from legacy VB code. Using C# capabilities, for example, VB apps could be leveraged with the web interface or powered with mobile access. This approach has proven itself many times over.   



By the time of the latest .NET Conference, named "Focus on Windows," it had become clear: Microsoft won't evolve Visual Basic as a language but will integrate it into the .NET environment. That leaves almost no choice but to migrate to the newest .NET version.   



How to Transfer VB to a Web App with Automation Tools 



As soon as the need for migration emerged, Microsoft (in collaboration with partners) launched specialized conversion tools transforming VB code to C#, VB.NET, and .NET platform. The recommended tools include:   



Microsoft Visual Basic Upgrade Wizard: a tool suitable for small and medium projects. It will partially migrate your code to Visual Basic 2008.    Visual Basic Upgrade Companion (VBUC): a more powerful tool to upgrade Visual Basic 6.0 apps to the .NET platform.    Code Architects VB Migration Partner: a tool for converting code from VB6 to VB.NET.     



In its documentation, Microsoft points out that these tools can’t be an end-to-end solution.

How Do Automation Tools Work?   



Transferring VB code with automation tools is a fast and cost-effective way to upgrade legacy software, compared to rewriting from scratch. The migration goes through a number of stages:    



Pre-migration work: This stage involves mapping out the entire process (setting up the software with the tool requirement) and making changes to the existing VB code. You’ll need to refactor, restructure, and remove unnecessary chunks for smooth code conversion during the transition.    



Automatic conversion: Set up the extension and run the program. It will parse the VB and ASP files, convert them, and write the equivalent .NET files. The same principle is used in a VB6 to VB.NET code converter. You can select options for the project's defined features.   



Manual changes: The stage involves fixing the different migration issues: removing duplicates, dealing with dependencies, leveraging the functionality, rewriting some parts of the desktop app, etc.    



Quality Assurance activities: Providers advise allocating about 35% to 50% of the total effort to run test cases in the new environment.

As we can see, conversion tools alone leave wide gaps in the migration. In any case, you should assemble a qualified team who'll handle the rest of the work (about 70%). But, if your project is simple and non-buggy, you needn’t be bothered with the manual work; you may be able to make do with the software only.



Disadvantages of Visual Basic Conversion Tools  



As we mentioned previously, conversion tools are imperfect. There are serious disadvantages of automated migration:     







Can’t deal with complex projects  



Enterprise users who have dozens of VB apps under one roof won’t benefit from conversion software. Even though software providers claim its efficiency for apps with 650K lines of code and more, they have many dependencies that are difficult to structure. As such, the amount of manual work will outweigh the pros of automated migration. From a practical standpoint, it's not cost-effective in the long run.     



Require lots of manual enhancements   



Developer communities are plastered with complaints about VB code fixes. For instance, folks from Stack Overflow encountered about 15,000 errors when compiling their code to C#. Sometimes they spend months polishing and debugging the codebase.    



Here are a few things that can’t be converted with VB conversion software and require a rewrite:    



ActiveX Document (COM-based components) Property Page Microsoft Data Report (*.dsr)   COM Crystal Report objects   ActiveX container 



The post-migration stage will also need plenty of architectural, performance, user experience, and security improvements.     



Low level of customization for the specific needs  



Most of the declared tools target a specific Visual Basic version: VB6, which is called a last release of the "real Visual Basic." Software providers write off earlier versions. But they still exist and need proper support.     



If you migrate the app without thorough preparation, you'll later face issues related to the business logic. As a result, you won’t be able to take advantage of the new platform.

Verdict   



If you need to migrate VB apps, we advise you to look to custom software development services. This approach can be tricky and complex, but you get predictable outcomes. 



Migration with automation tools creates gaps and could go sideways when you least expect it. As such, you'll need a qualified team to support your project at every stage. This means migration costs will rise until you get the work done. So, the cost-effectiveness of the conversion tools depends entirely on the type of the project.

### 5 Reasons Companies Move to the Cloud and What Prevents Them from This Step

Recent LogicMonitors survey results presented by Forbes magazine revealed that worldwide public cloud service revenue is expected to reach US$331.2 billion by 2022. 



It's not surprising, as in recent years we have been observing significant growth in cloud computing. The cloud has already managed to change key business attributes for most industries, including business models, revenue channels, and workload, and it's still growing in popularity. 







Why Do So Many Companies Decide on Cloud Migration? 



There are a great many arguments in support of companies migrating to the cloud. 



First, stakeholders are attracted to the reduced costs made possible by the cloud, as providers promise to lower operating costs by charging only for the used capacity. 



Second, cloud hosting enables companies to run their software infrastructure more efficiently and scale it in case of any business change.



Third, the cloud application can be accessed at any time and from anywhere, using only an internet connection.



One more huge reason companies migrate to the cloud without hesitation is simplicity. It is far easier to contract professionals in the field and get high-quality services than try to build a similar solution on your own. Cloud systems are highly complex and require on-time maintenance and dedicated staff, but not every enterprise has the budget for it.



Looking for a qualified cloud migration vendor for your project? Ask these 10 Questions to Validate Your Application Modernization Vendor Before Starting the Cloud Migration Process 



The above reasons for investing in cloud migration are all very compelling, but on top of them, we would like to highlight five more reasons companies are moving to cloud environments. 







5 Main Reasons Companies Move to the Cloud Environment 



 1. Cost Efficiency 





The cloud is a haven for startups, which don’t have the resources to purchase expensive hardware and don't have a clear understanding of future demand. The flexible payment models of cloud providers are based on a pay-per-use 





approach, allowing companies to save money by paying only for what they use. However, some experts say redundancy often occurs. Cloud solutions not only conserve funds, but increase revenue, according to Dell. 






 “Сompanies that invest in big data, cloud, mobility, and security enjoy up to 53% faster revenue growth than their competitors.”  




 GLOBAL TECHNOLOGY ADOPTION INDEX BY DELL



2. Reliability 





When your datacenters are located in-house, it's imperative to create a disaster recovery strategy to properly address any unexpected problems or setbacks you may encounter. Without a disaster recovery strategy you won't be able to ensure business continuity. With an effective strategy you can make sure any system collapse won’t last long and the disruption to the system will be minimal. Cloud service providers are experts in keeping their environments working seamlessly, so you don’t have to worry about disaster recovery. On top of this, all data can be mirrored at multiple redundant sites on the cloud service provider’s network, which 





 reduces the likelihood of losing it to close to zero, unlike desktop computing, in which a hard disk crash can destroy all data completely. Power failures, viruses, fire accidents and mechanical damage to hard drives are the main causes leading to data loss.



Blog hosting service JournalSpace closed because of users’ data loss due to either OS failure or human error. Unfortunately, they didn’t have backups, so every blogger who hosted their site on the platform lost their data too. The sad reality is that it can take only a minute for a six-year-old business to be completely destroyed. 





3. Global Scale 





Cloud solutions give you exactly the amount of resources you need at any given moment. You can increase the number of app users from 20 to 2,000 in one hour and the system will continue to perform on the previous level, providing more computing power, storage, and bandwidth from the right geographic location. In contrast, if you need to increase the  





bandwidth for an on-premises system, you’ll need to upgrade the infrastructure; that entails a full-fledged software development project, and it'll take time, manpower, and money. According to a survey by InformationWeek, one of the major reasons for a business to move to a cloud is the ability to meet business demands quickly. 





4. Productivity 





Another difficulty of on-premises hosting is the need to carefully manage the project. This means a lot of work for IT teams, including hardware setup and software patching. When using cloud services, however, you can leave most of “racking and stacking” tasks to the cloud provider, freeing up in-house IT teams to spend their 





time on more critical tasks. One more point that has a positive influence on software productivity is fewer bloated programs hogging your computer memory, as most of them are placed within cloud infrastructure. Thanks to cloud solutions, not only do your IT teams work faster, but so does the software itself. 





5. Ultimate Access 





When your employees work remotely, on-premise hosting doesn’t work, while cloud works perfectly an unlimited access anywhere 





 and anytime. It enables collaborative work for teams with traveling sales staff, freelancers and remote employees.

The Biggest Roadblocks on the Way to the Cloud



As you can see, the cloud undoubtedly has many considerable advantages. Why, then, are there still companies that are not willing to migrate to the cloud as soon as possible? 



Several cloud migration challenges affect the migration of businesses to cloud providers, and some of them are critical for organizations. So, what's in the cloud box that other software development companies won't tell you?



Data Sensitivity



In a recent Forbes article titled “83% of Enterprise Workloads Will Be in the Cloud by 2020” it was revealed that 66 percent of IT professionals say security is the most serious problem encountered when adopting an enterprise cloud computing strategy. Moreover, data isn’t always applicable for migration from the tech point of view; this makes the data migration process one of the most complex points while re-platforming your solution.



How can businesses overcome the data sensitivity issue? There are steps you can take in advance. First, take some time to get a full assessment of your current system, and then carefully plan the on premise to cloud migration process that will be performed by highly professional data engineers.



It’s Still Expensive



The Forbes article mentioned in the previous section refers to a report that states upfront migration costs often outweigh the long-term savings created by IaaS. Imagine company management performing a huge migration project that takes four years, investing an enormous budget and spending a lot of time managing the team that was hired just for this project. In the end, the earliest the multimillion-dollar cloud migration spending can be returned is in 30 years. It’s too long to wait for your return on investment, don’t you think?



How can businesses prevent inefficiency when it comes to the costs of a cloud migration? It takes some planning up-front. Don’t become a victim of enthusiasm; ensure that you start the project only when you have a cost-benefit project estimate. Sometimes it’s better to continue using an internal server than to move to the cloud.



Geography Matters



As the cloud is all about having a worldwide network, cloud providers can’t avoid the latency issue. If your company’s application uses a data center situated on the other side of the planet, it works more slowly than it would on a local connection. One more difficulty when it comes to geography is the diversity of laws in different countries. The attitude toward data sovereignty is not the same in Europe as it is in the United States, for example, so European companies are worried their data centers in the U.S. can be accessed by local law enforcement, while their own data policy is regulated by the General Data Protection Regulation (GDPR).



How can a company protect itself from geographical issues that may arise in the cloud? Just be aware of the geography issue and take where your data center is situated into consideration when you choose your provider. In fact, many leading cloud vendors have built regional data center networks to allow clients to keep their data within their region. In this way, Microsoft offers Azure cloud services from two data centers in Germany, so that stored customer data is under full German company control as a “data trustee” and even Microsoft can’t access it without permission (from the company or the customers themselves).




“A half of business owners say the increasing barriers to globalization threaten their ability to: consume or produce cloud-based services (54% agreed versus 14% disagreed); use or provide data and analytics services across national markets (54% vs 15%); and operate effectively across different national IT standards (58% vs 18%)”




ADAPTING BUSINESS TO A DIGITALLY FRAGMENTED WORLD BY  ACCENTURE



Lack of Business Flexibility 



Let’s be honest and recognize that big companies that have existed for decades are not so flexible, yet migrating to the cloud means fundamental changes in business processes. Even minimal disruption of business processes can cause a company to collapse, and the scale of this collapse depends on the size of the company. Bigger projects mean bigger risks, and it's understandable why companies prefer to avoid this. At the same time, fear of change can come at a much higher cost, as staying the same means ignoring opportunities to grow and evolve with the current market.



How can companies deal with the issue of business flexibility? Unfortunately, you probably can’t make your big company more flexible, but you can moderate the influence of cloud migration. We've seen the success stories of tackling cloud migration this way: for example, a mobile operator fully modernized the company software and, thanks to proper planning, it shortened the disruption of the telephone connection to one hour. 



Final Thoughts



Cloud technology is supposed to simplify business processes, improve productivity and optimize the use of resources. With all of its advantages, there're serious pitfalls of the cloud transition that you should take into account. So don't lose sight of your ultimate goals and choose a qualified vendor that will support you on each step of the cloud migration.

### Migrating a Legacy Application to a Service-Oriented Architecture (SOA) Guide

Staying up to date and relevant is the essential task of any business, entrepreneur, product owner, etc., that wants to “stay afloat” in the current market conditions. When it comes to software, especially business systems, user demands are ever-growing and fast to be satisfied by your competitors. To meet the common performance standards and evolve along with their demands, you should regularly upgrade and improve your legacy software.



And migrating from legacy to SOA — Service-Oriented Architecture — may as well just be the most efficient and versatile method to do that. In turn, neglecting legacy architecture modernization, migration, or, simply put, re-architecting, you are definitely not learning from the mistakes of others. A whole airport system once crashed due to a harshly outdated OS and rigid structure, while 90% of businesses right now are limited in system expansion opportunities due to a heavy dependency on their legacy software. 



So let’s figure out architecture-driven migration of legacy systems to cloud-enabled software — why you need it, what you will get out of it, and how to do it best.



What is Service-Oriented Architecture (SOA)?



Service-Oriented Architecture is a unique style of software design where complex systems are segmented into services delivered over communication protocols for ultimately more convenient, easier to maintain, and smoother performance. 



On top of that, this paradigm outlines the essential values and properties that an SOA product must focus on:




Concrete business values rather than separate technical specifics.



Strategic goals rather than advantages specific to a project.



Intrinsic interoperability rather than custom integrations.



Shared services rather than narrowly-directed implementations.



Flexibility rather than endless optimization.



Evolutionary refinement rather than the search for perfection from the very project kick-off.




These are all outlined in the SOA manifesto that was published back in 2009. 











The main field of application and practice of SOA methods is the business software niche. The whole paradigm serves the ultimate purpose of making business systems more manageable, convenient, and reliable overall by breaking down complex applications into easier-to-handle chunks. 



And this is exactly where a great use for legacy system architecture modernization arises. In particular, legacy solutions with a monolithic structure can be efficiently transformed into more versatile, smoother running, and easier to maintain systems set in motion by the microservices-based foundation. With the SOA approaches, many businesses nowadays manage to preserve performance and improve without losing some core assets.



Benefits of SOA-Driven Software Modernization Projects



The main benefits of moving your legacy application architecture to the SOA format are unprecedented. Namely, you are looking at revamping the old clunky monolith software by making it more dynamic and based on the separate logically structured moving parts.



Services reusability



Migration to SOA lets one start reusing certain underlying services to one’s heart’s content or even turning them into public third-party use assets. This allows for saving significant costs in enterprises big and small. 



The main thing is to outline legacy to new architecture patterns so as not to overly complicate the legacy assets and functions in their updated form (which may happen when your modernization vendor overdoes their job when rebuilding certain things from scratch).







Services scalability





The question of continuous scalability can be handled much more efficiently with SOA approaches. Thus, all you need to do is create more instances of certain services to handle the growing accumulation of data. As the load on your system increases, you simply add more bricks to handle “more weight.” This is an essential advantage of a services-based architecture. 





Compare this to the bulky, cumbersome nature of monolithic systems where you simply cannot scale up separate software elements. The only way to go is to expand the whole application, which ultimately results in higher memory consumption, intenser I/O traffic, and lower efficiency of caching.





Tech independence and loose coupling





The implementation of loose coupling in SOA systems along with the complete independence from technologies — these two factors make SOA solutions so much more flexible and rich with potential. In particular, developers can add new essential features really fast and easily, saving lots of time and budget. 





As opposed to that, monolithic legacy solutions are characterized by tight coupling and have interconnected modules. This really complicates one’s attempts to go in-depth into the codebase and involves interdependencies to analyze certain system specifics.





Profitable structuring



In the SOA system, all services are clearly mapped, and all business layers are logically structured and organized. This results in enabling the enterprise of any size to respond more dynamically to issues and changes in both technical and business aspects. Things become that much easier when you can take a certain brick and remove it or replace it with another without undermining the whole system.



No mono



The fact that SOA system services are separate and neatly structured means more efficient and convenient testing where one can easily narrow down problem areas and track particular issues. This is a lifesaver for businesses that are tired of putting a major effort into testing, debugging, and maintaining monolithic software structures.

Migrating Legacy Applications: Challenges in Service-Oriented Architecture



In order to achieve all the above-mentioned benefits of SOA for legacy systems, naturally, one first has to handle the legacy software architecture migration to SOA, which has its specifics and pitfalls. But if you know about the main challenges you are to face and how to get over them, the whole thing can go much simpler and hassle-free. The main factors affecting success in the migration of legacy systems to service-oriented architecture include the following.







Picking the right migration strategy



The first major challenge is understanding what exact parts of the legacy system you can/must/should move and how exactly you should do that. This requires thorough analysis and planning, during which you outline the components and objects that:




can be left unchanged and moved as they are;



should be rewritten or re-engineered from scratch in a new environment;



can be safely replaced with new assets and objects;



can be wrapped within a new interface.




Big systems can become too chunky to transfer



As much as the logical subdivision into services is a great way to make things lighter and simpler to manage, breaking down a huge system into tons of separate services brings new complications to the table. Thus, using too many services can significantly slow down the overall system performance. This is the major challenge of migrating a large-scale legacy application to SOA.



Managing all the moving parts



With multiple separate services lying at the core of one’s system, more individual management and maintenance are required, which can become a challenge. In particular, you have to thoroughly manage every service, translate every message they exchange and handle the bandwidth to achieve a sturdy service orchestration layer (which is essential for the whole SOA system’s success).

5 Tips for a Successful Migration of Legacy Systems to SOA Environments



Forewarned is forearmed, as they say, or “buyer beware,” as others say. Migrating to and configuring your legacy systems in SOA, you get all the chances not to risk any extra costs or profits, or business reputation if you know specifics from the start. Here are some pro-tips to help you with that.



#1 Run the Proof-of-concept



When it comes to legacy systems, you already know how exactly your system works, its ins and outs, operational properties, and other specifics. What you don’t know, though, is how it would work in a completely new environment. This is where the proof-of-concept stage helps avoid many complications and achieve adequate results in migrating the legacy solution to the SOA environment.



The PoC stage usually implies working on small transformation iterations and developing the essential functionality pieces to be seamlessly tested and put into the foundation of further system expansion. Taking it step by step and verifying the proper operation of each revamped element helps make the most fruitful SOA migration decisions.

#2 Go beyond standard software deployment and create an organizational culture to support SOA





The migration of legacy systems to SOA environments is a task that goes beyond your regular software deployment routine. Particularly, preparing the ground for the process, you should analyze a) the underlying development methodology; b) software design techniques; and c) business relationships with customers, suppliers, and partners (if there are any).





In terms of the development and maintenance approach, it is logical to focus on achieving the post-migration infrastructure that your in-house or outsource team can figure out hassle-free. Just to prepare for the future, it is also good to use common, popular tools and languages. The same goes for the software design specifics. 





Then, surely it is important to keep everybody involved with your software in line with the post-migration changes. This includes notifying and preparing users (both frontend users and administrators, support specialists, etc.), shareholders, partners, customers (potential or existing), suppliers, and others. 



#3 Use metrics for seeing the efficiency of migration



Certain KPIs or key performance indicators can help you evaluate the whole reasonability of your migration to SOA. These can include:




Time-to-market (SOA’s services reusability should help accelerate this);



Application usage;



Service quality;



Security;



Cost reduction and efficiency.




It’s your call how exactly to measure these KPIs. There are plenty of specialized tools just for this available online, and you can also consult with specialized vendors. In a nutshell, you need to capture the results your system used to bring as a legacy product for future comparisons. Then, you start capturing and analyzing sales, traffic, profits, load accumulation, etc., after the migration and look at what grows and what doesn’t.

#4 Choose a tech stack based on specifics



The ultimate choice of tech stack for migration to SOA depends heavily on numerous underlying specifics of your product. It is best to involve people who worked on it or at least maintained it for some time who can recommend the most appropriate tools and frameworks. Ultimately, the tech stack must be reliable and future-friendly (i.e., optimized for future changes, renovations, and improvements).



#5 Prepare the legacy software for new user conditions



Preparations from the first pro-tip go both ways. Thus, a migrated system should be prepared for a new number of users beforehand (and better make a safety margin here). For this, it is best to define the maximum of concurrent and named users in terms of strict SLAs. If there is a possibility, it is best to settle this moment with your legacy modernization vendor.



#6 Watch your governance compliance



Portfolio specifics, third-party contractor nuances, and other governance structures are affected by the migration as much as any other related aspect. That’s why they must be reviewed and extended over all the fields, people, and regulations affected by migrating legacy systems to SOA.

### What Is Legacy System Replatforming and When to Consider It

In the fast-paced world of technology, having outdated software at your disposal can be detrimental to your business. Legacy applications slow down your business growth, worsen user experience, reduce mobility and availability, and take away your scalability. There are several ways of software modernization approaches depending on the application architecture, among other things. 



In this article, we will discuss various options for migrating to the cloud, such as replatforming re-engineering, rehosting, and re-architecting. Software replatforming drew our attention due to its simplicity compared to other options, but is it really simple? In this article, we will address the reasons for considering migration, the benefits and drawbacks of each option, and give you some helpful tips.



What is Replatforming?



Legacy application replatforming (also called “lift-tinker-and-shift”) deals with moving some parts of a system without major changes to allow the application to function in the cloud. As a result, the application gains in scalability and benefits of the cloud environment as well as provides a better user experience. 



During replatforming, some code parts can be rewritten, or the way the app interacts with the database can be modified. The IT team does everything they can to ensure that the application suits the new cloud environment and benefits from cloud-based features.



Should You Replatform At All?



Unfortunately, there is no red light that goes off when your legacy system becomes outdated. It also does not happen in one day and usually starts in one part of the system and crawls its way into the entire app.



We have highlighted the five most vital signs for the necessity of legacy software replatforming that you should look out for at your company.







5 Signs You Need to Replatform Your Software



Failure to ensure security



The first sign of legacy software is its old age. Since these systems have been around for a while, they usually lack technical support from vendors that have developed them. Without ongoing maintenance and regular updates and bug fixes, old systems become vulnerable to security threats. Having your data exposed to cyber-attacks and security issues often leads to serious financial and legal repercussions.



Unfulfilled customer demand



Legacy applications do not receive the much-needed ongoing support for delivering new features, which leads to a decrease in user experience. Customers demand new capabilities and services, and without meeting their expectations, you are bound to lose to your competition. In the saturated market of various apps and technologies, users are accustomed to having a broad choice, and they easily make it after experiencing problems with an application.



High maintenance cost



Ever-increasing operating costs are another reason for immediate legacy system replatforming. First, outdated systems come with clunky and heavy code that tends to be cumbersome and heavy. Trying to understand and untangle it takes a lot of resources and requires stable ongoing technical support. Second, old code often causes issues with integration and development due to its incompatibility with new technologies, which makes the processes more expensive and lengthy.



Scalability issues



Scalability is one of the cornerstones of every software modernization service. Archaic systems often fail to deliver the much-needed flexibility and scalability to your company. Whether you are experiencing rapid growth or are forced to shrink, you need your software capabilities to expand and decrease with you.



Lengthy time to market



Out-of-date applications require significantly more time to launch even a small new feature. Old technologies are absolutely inflexible and require rare talents who are still familiar with them. Modern approaches to software development like DevOps or agile are not very compatible with old systems, which puts you and your product years and even decades in the past.



Replatforming is a way to overcome these difficulties and take a step into the new world of technologies.



Alternatives of Legacy Application Replatforming and Their Benefits



Should you replatform, you will benefit from several advantages for your business and development team. 



First, replatforming allows you to start small by tackling one area of the app at a time and scale up when needed. You get access to cloud-native functionalities without building a new solution from scratch using specialized coding expertise. On top of that, when you replatform in the cloud, you spend fewer resources than with other options like re-architecting and reengineering, thus experiencing faster ROI. 







Even though you can start small, replatforming tends to increase in scope leading to rearchitecting of the application. Additionally, the lengthy process of replatforming requires a high grade of automation to reduce human errors from the manual changes and copies. But what are the alternative options to replatform in the cloud?



Replatform vs. Rehost



Rehosting is the most popular way to modernize due to its simplicity and affordability. Rehosting refers to simply copying and pasting on-premises applications to the cloud without making major changes. Migrating an application “as-is” without any modifications allows you a fast-paced modernization process with minimum resources involved. 




Advantages




Rehosting provides a high speed of migration together with little to zero risk. This process can also be easily automated, allowing no downtime. 




Disadvantages




On the other hand, rehosting basically moves the application parts in the hope that it will work. Without leveraging the native advantages of the cloud, your application is bound to experience issues or at least not fully benefit from the migration. On top of that, the rehosting process is long and mundane and requires expensive activities when over.



Reengineering or Replatform



Should you go for re-engineering or replatform your application? Software re-engineering involves close investigation of application code and functionalities, aiming to identify redundant and unused parts. 



You begin with digging into the historic data about the application design, requirements, and specifications. Later, an IT team may improve the structure and code if they find it feasible. Re-engineering does not deal with major changes like the microservice approach of re-architect, replatform, rehost models. On the contrary, the re-engineering approach takes care of small changes like code restructuring, removing unnecessary parts, and code modulation. 




Advantages




Among the advantages of software re-engineering are better user experience and easier maintenance. Small incremental changes will increase the app’s productivity and performance and reduce the risks associated with deeper and more disruptive modernization scenarios.




Disadvantages




Despite many benefits, reengineering is a long process that requires thorough planning and a wide range of skills.

Replatform or Rearchitect



Re-architecting is also about migrating to the cloud, however, not blindly. This approach involves changing the app’s architecture to suit the cloud environment and unlock cloud features. Re-architecting is the most in-depth one and requires more resources and expertise. 




Advantages 




In the end, rearchitecting is highly feasible and delivers the best ROI and long-term cost savings. As it involves profound refactoring the parts of the software with redesigning processes, this approach is also more adaptable to changing requirements. 




Disadvantages 




On the other hand, due to its time consumption, you will be forced to extend your in-house team or hire a long-term vendor, making you vendor-dependent. Rearchitecting is also a highly complex process that requires a large variety of skills.

Verdict



All in all, replatform is the middle ground between the depthless approach of rehosting and reengineering as well as a groundbreaking and overly complex rearchitecting approach. It is far less invasive than rearchitecting; however, it still brings great results and allows you to take full advantage of cloud functionalities. Replatforming provides the optimal balance between invested resources and the outcome.



5 Tips to Successful of Legacy System Replatforming



How do you minimize the risks of legacy modernization replatform and make sure that the process goes well?



#1 Assess your cloud and business strategies



First, focus on your business goals and strategies for hitting them. Which features do you need to add or remove to get there? Which functionalities are hindering your growth? Prepare an explicit list of everything that should be modified before you begin to replatform a legacy application. 



Further, consider the choice of service vendor. Cloud providers offer various packages with different support levels depending on the scope of work and the application itself. Familiarize yourself with different cloud vendors to make an informed and data-driven decision.



#2 Set goals and performance standards



Set attainable goals that are backed up by relevant key performance indicators (KPIs). These standards give you a way to measure the success of the migration and make possible adjustments on the go. The KPIs might involve anything from a number of new users to page load duration; the critical part is pinning down the measurement that makes the most sense for your business.



#3 Avoid over-engineering



With the lack of planning and concrete goals, you might end up going off track and complicate the processes. This is why, when you replatform in the cloud, go for the basic platform and extend it with integrations and apps when needed. Much like with other modernization techniques, do not try to bite off more than you can handle. Focus on the established goals and milestones and do not move on to the next part until the previous step is over. This is where agile methodology can support you and make the transition from a legacy platform to a new one simpler and smoother.



#4 Keep track of your budget



Budgeting is a separate item on the to-do list that should not be underestimated and better be left to professionals. There are several approaches to the budget assessments that take into account different factors, but in the end, you should have a realistic estimate. Do not forget to incorporate extra for possible roadblocks and delays that tend to occur during a lengthy project. Finally, get a budgeting tool to keep track of the progress and make sure you stay within the budget.



#5 Prioritize the most valuable parts



Consider adopting an application strangulation technique that involves replacing a small percentage of old infrastructure with new pieces without disrupting its functionality. This model forces you to stay in small increments and always prioritize before making any changes.

### 10 Critical Questions About Migration to the Cloud

The shift to cloud-based technology services is a global trend you cannot deny. Over 94% of enterprises already use cloud services in their operations in some way, and even more are about to abandon their legacy software and employ a cloud solution.



There are multiple reasons behind such a move; the bottom line is that migrating to the cloud will most likely benefit your operation. The question then shifts to how do you handle the transfer to the cloud. To make this process easier for you, we’ve compiled a checklist of questions used during the migration of applications to the cloud.



1. What are Your Objectives with the Cloud Migration?



The first on the list of top questions to ask about cloud migration is: what do you expect your company to gain from it? Moving your operations to the cloud impacts your budgeting, flexibility, availability, security, and multiple other factors. You need to determine which are the most important to you to focus on them later on. Cloud migration depends entirely on your goals. If you’re not sure about what you’re trying to achieve, ask for professional advice.



Determining your objectives and ranking them in order of importance will help you distribute the resources you’ve allocated for the transition. It will also help you to choose the strategic and tactical approach to the process.







2. Do You Have the Resources Available to Support the Move?



The next item on the list of critical questions about migration to the cloud is what capabilities you actually possess to support the moving process. This includes time, money, experienced employees, technology expertise, and more.



Overall, you need to perform a cloud readiness assessment of your company. And it needs to be thorough — if you overlook anything, it might impact the move and result in unforeseen challenges. If you determine that the cost is too high for your business, it might be better to drop it.



3. Should You Tackle It Internally or Outsource It?



If your IT team does not have a skillset or appropriate technology expertise to support the move, it might be better to outsource the migrating effort. While hiring an internal team gives you more control over the process, outsourcing the effort frees up time to focus on your core values.



Nowadays, more and more companies choose the mix of both approaches. They expand their internal teams with other specialists. This approach has multiple benefits, like experience-sharing and more effective resource and workload distribution. This makes system maintenance easier to manage internally later on.

4. How Flexible is the CSP?



A cloud service provider (CSP) is your main partner during the move from your outdated system. That’s why one of the most critical cloud migration questions to ask is who they are. Can you trust them with your database, and will they ensure a quality service at all times?



An important aspect you need to consider while choosing the CSP is how flexible they are. Will they allow you to add any controls of your own? Can you order additional services at any time? If you know what you need from the provider, you should not compromise and ask for anything less. If you want to pick a trustworthy provider, and you don’t want to forget anything important, use our checklist as a guideline.



5. Do You Have a Migration Strategy?



Next on the list of cloud migration questions is whether you have a detailed strategy on how to perform it. Having the right plan can make or break the process, so you need to be prepared well before you start.







Numerous migration strategies can be employed, but there are three main approaches you can use for software modernization:




Rehosting — moving an existing application to the cloud as it is. This way, users don’t have to learn features of a new application, and you will get the benefits of cloud infrastructure;



Replatforming — moving an existing application to the cloud while changing the underlying technology. This way, you can ensure improved performance and take full advantage of the new platform;



Repurchasing — replacing a legacy application with a modern cloud-based solution.




Organizations often ask what to choose: replatform vs rehost? But the answer is based on 2 arguments: company's goals and the state of the existing system. 



6. Can You Do It Without Affecting Daily Operations?



This is one of the questions on cloud migration that concerns a lot of owners. Ideally, you would want to minimize the impact of migration on your operations. However, it is almost impossible to avoid any cutover — a period when the old system is no longer in use and the new one is not yet operational.



You can make the cutover time not as impactful on your operations by detailed planning of each step and having a skilled team by your side. Start preparing long before the cutover starts to have time on your side.







The matter of business continuity was vital for one of our clients who took on the migration path. His legacy Webforms system was clunky but it held all of the core processes. Our latest case study explains how to migrate to Azure without business disruptions in simple Azure migration steps.  



7. Who Will Manage Security?



If data security is of utmost importance to your business, this is one of the most important questions to ask during data migration to the cloud. You need to trust the person behind it, and if it’s entirely in the hands of your CSP, it’s not an ideal situation.



You also need to choose the right tools to monitor, validate, and ensure data security. This will help you to manage any hiccups that might occur during the transition.



8. Did You Validate the Legacy Vendor?



Before you start to actually work with somebody, you need to make sure you can trust them. Ask the right questions to determine the strength and weaknesses of each of the legacy vendor options to pick the best one for your business. Check whether they conduct the risk assessment, execute the migration of databases, provide a rollback plan, and are flexible during the change management.



9. What is the Cost and Timeline for Cloud Migration?



The answer to this question depends a lot on your specific situation. However, it is essential to get a detailed and accurate answer since it will help you create the strategy and manage it on a better scale. You can get some help from a business analyst to get a more accurate answer.



10. Can the Apps be Further Optimized, and are They Scalable?



After you’ve answered all the questions during the migration of applications to the cloud, you need to consider the questions on the operation after the moving. As your company needs to be constantly evolving, you need to ask whether the applications you use can be optimized even more. Another important question is whether they will be able to accommodate your business if it keeps growing.

### The Cost of Maintaining Legacy Systems: How Much You Overpay

Despite the onslaught of revolutionary digital trends and technological advances, many companies still use legacy systems. This may sound puzzling at first glance. Why would any modern company want to stick to outdated legacy systems? 



For instance, government agencies, national banks, and other financial institutions still use legacy systems today. Most companies who choose to maintain their legacy systems do so for presumably good reasons. These systems are quite efficient and allow continuity in business operations. Some may even argue that the cost of legacy software maintenance is cheaper than updating to modern alternatives.



Unfortunately, maintenance expenses represent only a tiny piece of the entire cost. A more in-depth analysis of the cost of maintaining legacy systems vs. updating the systems would show that the former is considerably more expensive. 



This article will discuss the hidden cost of maintaining legacy systems, how much you overpay to keep them running, and why you should start the process to reduce technical debt in your software.



How Much You Overpay to Maintain Your Legacy Software



Although it may seem like you’re saving costs when you don’t spend resources updating your software it costs more in the long run. According to a study on the cost of maintaining legacy systems in the United States, ten of the government's legacy systems cost about $337 million a year to operate and maintain. 



Legacy systems can cost any organization up to a 15% budget increase every year for maintenance. As a result, modernizing your legacy software might be a better alternative due to the risks and cost implications of maintaining outdated software. However, it still needs to be done right, as there are some common mistakes in legacy software modernization you need to avoid to succeed.











At this point, an obvious question would be: why are legacy system maintenance costs so high? Well, it’s quite straightforward — keeping an outdated system, you cover both main and hidden costs.



The Main Costs of Legacy Systems



Previous studies have shown that organizations have been spending large sums of money supporting, maintaining, and implementing legacy software. Statistics have also revealed that banks and insurance companies dedicate up to 75% of their IT budgets to preserving their legacy banking system.



As a result, companies should evaluate the financial risk factor of maintaining their legacy systems compared to updating to modern solutions like SaaS and PaaS.



The main on-the-surface costs of legacy systems include:



Resources for ongoing management



Legacy systems require constant attention and resources so that the outdated solution does not cause any major failures. With time, it will also be harder and harder to find knowledgeable professionals able to manage the system effectively.



The need for highly skilled tech support



Troubleshooting a legacy system requires a high level of expertise. Moreover, skilled tech support help might be needed to employ a newer tool to ensure compatibility with the legacy system.



Requirements for special licensing



In some cases, discontinued legacy solutions require special licensing to be used. For example, the US Navy pays millions of dollars to keep safely using Windows XP on their systems.



6 Hidden Costs of Maintaining Legacy Systems



Generally, using and maintaining legacy systems come with a significant decrease in performance and profitability. However, there are several other hidden costs submerged under the general umbrella of stunted performance.





These costs appear in various business areas, including data security, customer experience, testing legacy code, employee experience, skill acquisition, performance, and productivity.





Despite being ‘hidden’ from plain sight, these costs can hinder business operations or even grind them to a halt. Let’s go ahead and discuss the hidden costs in detail.









The burden on the IT department



Maintaining or working with outdated legacy systems can put a considerable strain on the IT department and impair productivity. Since the system contains bugs, the entire workload will focus on finding and fixing these bugs instead of mission-oriented projects. In the long run, this could lead to an increase in the number of dissatisfied employees and a corresponding decrease in performance levels. 



Maintaining or upgrading the database





Data is the driving force for any operation within the company. Legacy systems often lack a centralized data processing module. Even those with data processing systems have a disorganized framework. As a result, most companies often have to spend a sizable fortune on upgrading legacy system databases.





Besides, legacy databases like Microsoft Access or SQL Server are a challenge to turn into a competitive advantage albeit easy to set up. And failure to configure them may lead to significant data loss and damage your brand’s reputation beyond repair.

Ensuring security for data



Legacy systems are not secure enough, which is especially critical as long as every modern company handles users’ confidential information to operate. These systems come with several hard-to-fix vulnerabilities, which could lead to a data breach or total loss of data. 





The most notable example is the BlueKeep security vulnerability that affected NT-based Microsoft OS. Although Microsoft released patches later, the damage had already been done. Eventually, the affected companies still needed to pay extra fees to upgrade the security protocols and replace the lost data.





This necessitates constant security upgrades and maintenance checks. An easy solution to these problems associated with legacy systems would be to migrate your software from desktop to web or provide cloud migration. This way, your company can perform efficiently and productively. Maintaining outdated legacy software will require your IT staff to undergo special training to equip themselves with the necessary skills.





Frequent downtimes



Legacy systems may frequently experience downtime, which could wreak havoc on departments or cause financial losses to the company. For instance, if you are running an accounting legacy software, downtime during work hours could freeze cash inflow and prevent your business from generating revenue.



Poor customer experience



In several instances, low-performing legacy systems have led to dissatisfied customers and reduced cash inflow for the company involved. For instance, in 2015, a Paris airport was shut down after a 23-year-old Windows 3.1 system crashed in bad weather. Planes were grounded for several hours, with disgruntled customers left stranded. 



The customer experience is vital to any company’s success in today’s competitive market, and as such, using legacy systems is detrimental to your business.

Missed business opportunities



Up-to-date software empowers your business growth as it includes new features that boost process optimization, better data flow, and analysis, or even overall productivity which results in revenue growth.



The newest software development trends focus on better integration and interconnectivity between parts of the system and deeper processes automation. If you miss out on them, you will lose many resources you might’ve saved and repurposed.



The Benefits of Transforming Legacy IT: Our Experience



One of our clients decided to improve the performance of its enterprise system that was running on AngularJS. He spent astonishing sums on the maintenance until the migration to the newer version. AngularJS to Angular migration is also an important issue due to the end of support of AngularJS, Angular’s compared ease of use and speed, and many more.



We have helped several clients migrate successfully from AngularJS to Angular in just two phases that span between 8 to 11 months. To ensure client satisfaction and project success, we take several strategic steps.





First, we begin by analyzing and establishing the full scope of the project. Then, we assess the risks, explore legacy infrastructure, map out detailed mitigation strategies, and ensure continuous communication with clients every step of the way. 





In the past, most client companies had to spend significant sums on multiple third-party tools and developers. However, after migrating from Angular JS to Angular, they discovered that they now spend less on third-party tools since Angular has a Command Line Interface (CLI).





This migration process also helped clients pay lower fees as it makes maintenance and debugging easier. Furthermore, it helps to accommodate the rise in numbers of consumers and overall better react to the changes in market needs. If you decide to resolve the same issue, you will need to hire experts to map out strategies for implementing the migration plan. 







Conclusion



Maintaining legacy systems only leads to far too many overheads and hidden costs that may be detrimental to the company’s success. And most importantly, they can bankrupt the company in cases of data loss or software malfunction. 



By choosing the right modernization strategy, you can easily cut down the high legacy application maintenance cost by half and increase productivity.

### Advantages and Disadvantages of Legacy Systems. What to Choose — to Maintain or to Modernize?

Today, most companies are conflicted about abandoning legacy systems for newer alternatives. Even with new technologies replacing old ones, some agencies still have difficulty adopting the "in with the new, out with the old" mantra. 



Today, legacy systems are relatively widespread across many industries, and most federal agencies are not left out. 



A 2019 study carried out by the US Government Accountability Office (GAO) identified 65 legacy systems ranging from 8 to 51 years old, with about ten critically in need of modernization. However, only about seven out of the ten agencies responsible for these legacy systems had documented modernization plans as of 2019. 



But with the COVID pandemic, some frailties of legacy systems have been exposed. A well-known example is the case of held-up unemployment stimulus checks because the payment management system was written in COBOL — one of the oldest programming languages. 



So, is modernization the answer? What are the pros and cons of legacy systems? 



This choice is difficult since many agencies are conflicted between modernizing and sticking to legacy systems.



This article will address the pros and cons of modernizing and maintaining legacy systems, as well as provide guidelines for choosing the best option.



Pro Tip: If you aren't sure about how popular legacy systems are in today's world, here are the five most famous examples of legacy systems.



What Is a Legacy System?



The term ‘legacy system’ came into existence in the 1980s to refer to computer systems that set the standard for software in the future. Although this name suggests that the software is ‘out of date,’ a legacy system can still function and solve problems.

The entire workflow is smooth since everyone knows how to access records and use the software. As such, it makes it easier to carry out daily tasks with no hitches whatsoever. 



Legacy systems are efficient for specific tasks



Efficiency is another legacy software advantage. Some legacy systems, despite being old and outdated, still work perfectly fine. And most importantly, these systems are typically designed for maximum capacity and remain reliable and durable in most cases. 



For example, banking systems use legacy systems and mainframes to facilitate most of their transactions. And although legacy systems in banking might be difficult to maintain, they are still efficient in carrying out day-to-day operations.



Legacy systems ensure continuity in business operations



Modernizing software or switching to entirely new technology is a delicate process that could put business operations on hold. Alternatively, maintaining the status quo (legacy systems) lets business operations run smoothly with no hitches or pauses.



Legacy system replacement is painful 



Tons of new technologies are currently taking over industries globally. However, switching from a legacy system to entirely new technology can be a resource-intensive task for any company. And when you acquire new software, you need to hire and train specialists to use it as well as consider all associated risks.



Primary Disadvantages of Using Legacy Systems



Now that we've outlined the legacy systems pros, let’s discuss the disadvantages of legacy systems. 



Do legacy systems pose any potential risks? What are the legacy systems' cons? Let's find out.



Compatibility issues



Legacy systems may support certain data files and formats at the beginning. However, these standards often evolve beyond what the legacy system can handle after a short time. 



Since old software cannot handle modern technological demands, companies would struggle to meet their business goals. Consequently, these businesses would end up losing essential opportunities. 



Limited flexibility



Legacy systems usually offer limited flexibility, which makes them challenging to change or customize. As a result, companies struggle to cope with the evolving industry’s rigors, highlighting one of the primary disadvantages of legacy systems' flexibility. 



On the other hand, modern systems are more flexible and can easily adapt to updates or technological advancements. 



Functionality issues



Reduced software functionality is a crucial legacy software disadvantage that companies may face from time to time.



In most cases, the system would be unable to run and integrate certain software programs or carry out specific functions. 



A tragic example of the functionality issues posed by legacy systems is the Comair airline company tragedy. Software malfunction cost the company around $20 million and badly damaged its reputation, culminating with the CEO’s firing.



Old interface



Most legacy systems have old interfaces, which is one of the disadvantages of maintaining legacy systems. In today's world, an outdated interface can hurt any business by derailing customers’ trust in the brand, leading to a decline in sales. 



In the same vein, an outdated interface provides a horrible user experience. The displays are difficult to read, and the data is challenging to interpret.



Learn how to modernize the user interface of your system. Risks and Approaches of Legacy Application UI and UX Modernization 



Costly maintenance



The U.S. Federal Government was forced in 2018 to spend nearly 80% of its IT budget on the maintenance of outdated legacy systems. This case highlights the possible financial implications of not modernizing legacy systems. Besides, legacy systems require the expertise of skilled technicians, which is currently in limited supply.



And this is how much you overpay for the legacy software in your organization The Cost of Maintaining Legacy Systems: How Much You Overpay 



Security vulnerabilities



Legacy systems are prone to malware attacks from bad actors. The absence of software patches and upgrades leaves the legacy system susceptible and defenseless to potent attacks. And eventually, they end up spending extra to support the system while paying for special licenses.



Should You Choose to Maintain or Modernize Your Legacy System?



This question is the crux of the discussion in this article. The short answer is: it all depends on your company’s objectives and overall budget. To get a general idea, take a look at the graphic. Every system reaches a ‘dilemma’ zone, where new technologies and adjustments are needed to overcome this threshold. And ignoring the signs will make the system stall or malfunction.







Here are some signs that should tell you if your legacy systems need to be modernized.



The software no longer supports your needs



Legacy systems are problem-solving technologies in the early stages. But once this problem-solving system transforms from an asset into a liability, consider modernization to avoid further losses. 



The system cannot keep up with your current business growth



Businesses are constantly growing and evolving. If your operation scale expands and your system can't support increased production capacity, then it's time to change it. Most importantly, go over your company's long-term objectives to determine if modernization can protect the company from any potential setback. It's a clear example of why companies change from .NET Framework to .NET Core just to keep up with modern web and cloud trends.



A recent industry survey by TCS revealed that the pandemic is validating CIO’s digital transformation initiatives, as remote work becomes essential while legacy systems can’t keep up with them.



 VIEW CASE STUDY  







The system lacks security updates and patches



Old systems are more vulnerable to malware attacks and breaches. Updates and patches help to prevent these attacks by closing security loopholes. As such, it's best to modernize your system to avoid getting attacked. 



Increasing technical debt



Legacy code with poor development practices creates technical debt. As the solution overgrows with dependencies, it becomes hard to maintain everything in the future. Thus, companies spend nearly 70-80% of the IT budget to finally reduce technical debt.

### How to Effectively Conduct a Legacy System Integration

More and more companies face the unsatisfying reality of dealing with legacy systems and conclude that they should make a change. However, a significant portion of such systems supports daily business operations, making it difficult to rip and replace them entirely. 



Did you know that nearly 97% of all collected data ends up being just stored away and never gets a chance to be used again? On top of that, a big part of this data is outdated and redundant, delivering little to no value to the company. But you can change that by reactivating your legacy software. 



Luckily, you don’t need to disrupt the whole IT environment to get a new technology platform. After having invested money and time into your legacy application, a complete overthrow of the entire system seems like a waste, right? There is a way of adopting newer technologies without starting from scratch. Instead of building a brand new application, you can upgrade your old one by implementing a method called legacy systems integration. 



But what is legacy system integration, and is it relevant for your business? 



What Is Legacy Systems Integration?



Legacy system integration deals with connecting APIs on-premises and in the cloud. In other words, it transports data from on-premises legacy systems and advancing new systems that drive the business further. The main challenge is to detect an outdated system and ensure communication between it and the cloud applications. Legacy system integration is also necessary for untangling the so-called spaghetti code when integrating a company's internal systems. 



When Is Legacy System Integration Relevant?



How can you tell if you have a legacy system on your hands and whether it needs modernization? What are the main reasons to integrate legacy systems? There are eight of them: 




Shorter time-to-market




44% of organizations that offer financial services state that integrating new technology is one of the biggest pain points. Integration of a new solution into the existing environment becomes a hardship on the way to digital transformation. Luckily, legacy system integration helps you build a lightweight product that will present a competitive advantage. On top of that, this process speeds up time-to-market and allows you to deploy more frequently. 






Increased performance




Newer technologies come with better performance as well as more reliable and smooth processes. Additionally, modernized solutions reduce security risks and facilitate better functionality. 






Access to buried data




As mentioned before, 97% of data gets lost and forgotten in legacy systems. You can improve your business processes by unlocking the value of data and utilizing it. 










Improved agility




By adjusting your IT environment to fit into the agile and cutting-edge present, you leave a bigger window for future changes.  




Easier to follow data compliance standards




Some industries, such as healthcare, require a specific process of data transfer. Outdated legacy software cannot ensure this strict flow and hinder changes. 






Smoother integration with third-party tools




Newer systems like CRMs, accounting software, and other third-party tools open up new opportunities for your business. However, to capture the benefits of modern systems, you need to bridge the gap between the legacy software and the new system. 






Eliminate financial inefficiencies 




Every IT business strives to be modern and up-to-date, which is hard to achieve when you keep using outdated software. Jumping on the innovation train will improve your company image and might even attract investors. 






A valid alternative to legacy system replacement




Integration is far less invasive and expensive than a complete replacement of a system. Unlike smooth and continuous integration, the latter requires bigger investments, resources, and time.



 VIEW CASE STUDY  



3 Types of Integration of Legacy Systems



There is more than one approach to the integration of legacy systems, but we’ll focus on the three basic ones and the one ready-to-go. 



Service layers



Adding service layers is a common strategy when it comes to legacy systems modernization. They act as a mediator between your outdated application and a new system. Service layers transform the data before it hits the new or existing system. 



Data access layers (DALs)



Data access layers act as a database that allows developers to use various data stored and access information easier. They also facilitate a separate modification of logical data that won’t affect the business layer. This is a beneficial trait for any system, including modern ones, especially when a need to extend comes up. Using DALs, you’ll be able to replicate a data solution that will allow you to deploy a business or data intelligence or artificial solution. 



Application Program Interfaces (APIs)



As one of the most common legacy system integration models, APIs unmask functions of your legacy software to outside integration and make the process significantly simpler. APIs provide the much-needed flexibility and ensure better performance. 







Ready solution for legacy systems integration



Instead of executing the cumbersome process of integration by yourself, you can purchase a ready-made solution. Some companies offer a simple solution for seamless integration, thus solving the problems with legacy infrastructure. Although it is a more cost-effective option, there is a catch. Ready solutions usually pose a greater risk of sensitive data loss. You will be better off choosing a vendor who will develop a custom solution for your business and control every step of the process.



Which Legacy System Integration Issues You Might Face and How to Solve Them




Lack of necessary documentation




Modernization of legacy systems is not an easy task and requires constant maintenance and expansion. Furthermore, legacy systems require a lot of patching. Most of the time, companies face a lack of comprehensive documentation to the system architecture as well as system changes and patches, which makes the process longer and more challenging. 



Solution:



Although you cannot uncover the lack of documentation of legacy code, the best way to avoid these mistakes is to develop a set of standards and processes for the future.








Monolithic systems




Monolithic systems pose a big challenge to legacy system integrators. The way they are built does not allow to separate their functional aspects like error handling, user interface, and data processing. Monolithic architecture implies that the components are blended and not architecturally separate, making integration significantly more difficult. 



Solution:



Here you should conduct an architecture audit to determine whether you want to keep some parts of the old system and assess how new parts will interact with old ones to prevent disruption. 



How to switch a legacy monolith architecture to a Service-Oriented Architecture (SOA). Read the practical tips. Migrating a Legacy Application to a Service-Oriented Architecture (SOA) Guide 








Talent Gap




The talent gap derives from the lack of programmers that can write code using legacy programming languages. According to research made by Veeam, 44% of companies state they cannot proceed with modernization plans due to a lack of necessary IT skills on the market.



Solution: 



If the situation occurs when the technologies are so outdated that you cannot find anyone to command them, you would need to rewrite separate components using new tech stack in the process of modernization. 








Security Risks




One of the biggest issues of working with legacy software is their vulnerability and risk of exposure to security threats. The integration process itself is also prone to security risks due to the transfer of sensitive data between on-premises and cloud solutions and the non-availability of software patches. 



Solution:



The right vendor will help you assess the risk exposure and avoid or at least mitigate these issues. If you are unclear with the process of vendor screening, read our explicit guide on how to validate legacy vendors. 



Integration as a service is the most common way to facilitate real-time exchange of data between legacy/modern systems and avoid being trapped in outdated technology.

### Risks and Approaches of Legacy Application UI and UX Modernization

“Redesigning a legacy app is like an archeological dig, forcing you to push the limits of creativity within very specific boundaries.”



Jamie Myrold, VP of Design at Adobe







Is your user experience rate suffering, and do you keep receiving negative feedback? A lot has changed in recent years by virtue of technological progress: in marketing, human resources, and, of course, in UI/UX design. 



Even if your product has real value and can make everyone’s life better, you need to focus on customer experience. Regardless of the service provided or whether you produce for the B2B or B2C market, the user interface remains crucial for both ERP and CRM systems. That’s when you should reconsider your current application and think about modernizing your user interface. 



What is a legacy application, and what does it have to do with user experience? What are the benefits and challenges behind UI/IX modernization? Read on as we answer these questions.



What Is a Legacy Application and What Qualifies for a Legacy App UI/UX Modernization?



Legacy application refers to outdated software that no longer has updates and technical support. You can keep running it, but sooner or later, you will lose to the competition. Continuous innovation and legacy app UI/UX modernization are the ways to win, and without perfecting your design and getting constant feedback, your company will hit the brick wall. 



If you think that your application is not old enough to be redesigned, you might want to reconsider — it is not only about its age. Applications in need of redesigning legacy systems are generally cumbersome and difficult to adapt. Their architecture and technology are inflexible, making them hard to maneuver and change under current trends and requirements. When you have a legacy web application, every move you make requires a ton of valuable resources, including time and money.







Guaranteed user base



Since a majority of legacy apps are built for enterprises, they miss the value of customer experience on day one. Many of them do not take into account the diversity of employees, their responsibilities in the organization, and the required data. When an application is created to suit everyone’s interest in one package, in the end, it doesn’t fit anyone’s. Without a decent level of customization, there will always be users who remain unsatisfied.



Cumbersome UI



Being built for a multitude of users who have no choice but to use it, legacy web apps mostly lack a customer-oriented user interface. Unlike software developers who continuously monitor user retention, traffic, and customer experience, legacy software producers tend to overlook the importance of these metrics and end up with an unsustainable application. Moreover, many legacy apps require special training before working with it due to its unnecessary complexity and inflexibility.



Lack of choices



Management executives have a truly tough choice: they either buy something off the shelf or build an app from scratch. The former is significantly cheaper and faster; however, it can probably miss some vital features to fit each employee’s needs. The latter has its own disadvantages because building and designing an application is a long-run and complex process that requires a clear understanding of each and every operation in the organization. Finally, creating a custom application will cost you a small fortune and require many iterations and revisions.



Possible miscommunication



Who will make the final decision about software? Certainly, corporate management that deals with only a few metrics, functions, and procedures. Mostly unwillingly, they will overlook a large number of future users who will not have a say in the decision-making process. This inevitably leads to a gap between what the executives think is suitable for the company and what is actually important to workers.



Why You Should Consider Legacy Application UI and UX Modernization



Having paid a substantial amount of money for a web application, many corporate decision-makers will wonder why they need to invest even more money in modernizing legacy UI/UX. Why should they fix software that works fine? Will the investment even pay off?



Let’s look at some numbers that will finally convince you that legacy UI/UX modernization is the key:




According to statistics from Forbes, $1 investment in the UI/UX design generated from $10 to $100 gain, which means that modern UI design recruits new and more qualified employees;



44% of CIOs say that legacy software significantly holds back the company’s growth;



14% of organizations that invested in UI modernization have increased their annual revenue.




Legacy UI/UX interfaces can also incur technical debt. Learn about the proven ways to cope with it. Technical Debt Reduction in Legacy Systems: How to Do It Efficiently 



What makes this step so vital, and why should you strongly consider channeling your money into UI/UX redesign?



Increase in productivity



Having worked with your legacy app for a while, you can conduct thorough user research to have an in-depth understanding of the work your employees perform. Considering human factors, fossilized mistakes, and user feedback, you can restructure the interface in the way your employees need it. Thus, you can apply time-tested behavior patterns, human memory, and perception principles to shorten the user path to complete an action. 



Therefore, your employees will complete their tasks easier and quicker and generate more profit for your company. Finally, due to diminished complexity and more intuitive navigation, employees will perform with fewer errors, leading to human error cost reduction.



Our cases studies prove that software modernization pays off. 3 Legacy Software Modernization Case Studies and 12 Lessons We’ve Learned 



Enhanced security compliance



In the modern world of sharing sensitive information online, many users are concerned about their data security. Both stakeholders and employees are interested in raising security and protecting their data from cyberattacks, as the latter can lead to expensive lawsuits as well as a poor reputation. 





In the modern world of sharing sensitive information online, many users are concerned about their data security. Both stakeholders and employees are interested in raising security and protecting their data from cyberattacks, as the latter can lead to expensive lawsuits as well as a poor reputation. 





Furthermore, cross-functional development teams provide an opportunity for a harmonious tandem of security and UX. Design and security shouldn’t be neglected or left as an afterthought. 



What does one have to do with another? One of the common security issues are injections, whereby an attacker uses a regular form on the web page to run their code and gain access to sealed data. By modernizing your software and design, developers can limit the input settings and avoid potential misuse.





Finally, the absence of vendor support paired up with the lack of skilled professionals poses a threat to your company’s security. 



UX best practices for improved customer experience



UX design is one of the biggest trends in software design. Its importance cannot be underestimated since there’s such a fine line between success and failure. We’ve all seen and used so many applications that we have clear expectations before getting into a new one. Intuitively, your customers know where to find the menu, the logo, and the search bar. Creativity is a part of any design; however, over the past years, many unspoken rules have been developed that you should not neglect. 





When you modernize legacy UI/UX, you decrease the learning curve for new employees and create additional value for them. Boosting both employee retention and effectiveness, you increase revenue and the overall success of your corporation.





How do you ensure all of the above? By uniting UX professionals, software developers, and end-users feedback. For example, based on the received feedback, the user interface might need to be altered to comply with security policies and provide more safety, so including UX designers in security reviews is very important. 





Better reputation



Reputation is a combination of values that your brand represents and its perception by customers. When you build a strong reputation, you cannot limit yourself to only one value but try to achieve the best results in every aspect. Next to the quality of the product, employee benefits, and office location, enterprise application plays an important role in your company’s overall image. In order to increase brand value, you have to be able to empathize with your employees and provide better solutions. 



Main Risks and Challenges of UI and UX Modernization



Phased improvements



Legacy application GUI modernization is a long process that requires structuring and planning. On the other hand, it has to be carried out without interrupting any existing functions. This is why it is vital to focus on listing the needs of end-users and what should be upgraded in accordance with their requirements. 



Planned pivots



During the process of redesigning, you will choose UI and UX modernization approaches create phased launches that will generate valuable feedback. Thanks to beta testing, you will receive feedback from your users and pivot your initial features to meet their needs. Although it is a very productive approach that allows you to satisfy everyone’s requirements, it takes a lot of time and effort. 



Creating value for employees



The initial goal is to promote user experience and make your organization more attractive to them. Therefore, if new software is too complex or does not cover everyone’s needs, it will not be successful.



VIEW CASE STUDY 



The Go-To Legacy UI/UX Modernization Approaches



Making something from scratch is always easier than fixing something that is failing. Web app facelift is a challenging task for UI/UX designers and requires juggling different approaches at once. There is no one single magical tool that will fix your legacy software, so it is important to find the right balance.



Redesign



A redesign is a tricky approach that often requires help from third-party providers and business consultants. With this approach, you will start from scratch: user and market research, setting goals and expectations, and defining the main problem. 







When redesigning UI/UX design, bear in mind the following key principles:



Define reasons



Do not forget that you are generating value for the organization. Before you start the process, identify the reasons for the modernization. Communicate with the end-users through emails and surveys and collect the list of features that should be added to improve customer experience. 



Focus on efficiency



Recreating the user interface the way users want to have it will boost the efficiency of your company. User satisfaction can be measured by task success and various KPIs; for example, how long it takes to complete a particular task, its result, and the number of errors that occurred during the process. 



Make sure the new user path leads them to a successful and fast-achieved result.



Ensure collaboration



In order to build a system with a shared understanding among stakeholders, developers, designers, and users, you need to collaborate. Only by working together and considering user feedback will you create an application that covers everyone’s needs and meets everyone’s requirements. 



By continuously checking with each other, your company will develop a platform that makes every member feel included and valued, which also eases the learning curve and makes your app simple to use. All in all, it’s clarity and simplicity you have to prioritize while redesigning a legacy app.



Concentrate on usability



Making your system easy to use allows you to shorten the learning curve and save money on various training. Moreover, you help new, and existing employees avoid frustration when working with the program and enjoy the smooth process, which improves their productivity and efficiency.



Continuous improvement



Instead of throwing away the old application, the company will work to improve the existing GUI and technology and add features. 



This method, used alone, is quite ineffective due to gaps in feedback, which might send the company down the wrong path. Moreover, integrating new features in the existing system that continues to function is not an easy task. Besides, by continuously adding new features, you might overlook the moment of making the system way too complex and cumbersome, especially without a streamlined documentation process.

### 10 Key Advantages of Cloud Computing for a Business

A growing buzz around cloud computing means almost everyone has heard about the topic. On top of that, the most famous digital companies use it in their operations. Instagram, for instance, used a public cloud to store users' photos, until the app was bought by Facebook and storage shifted to the social media giant's private cloud. Why did they make this decision, and how can you get an understanding of which cloud computing option is the best fit for a particular company? Let’s dive deeper into cloud computing and look at everything we know about the cloud. 



What Is Cloud Computing? 





Oxford Dictionary defines cloud computing as the practice of using a network of remote servers hosted on the internet to store, manage, and process data, rather than a local server or a personal computer.



Let's look at Microsoft's definition of cloud computing. Cloud computing is the delivery of computing services such as servers, storage, networking, software, databases, and analytics over the internet in order to provide flexible resources, rapid innovation, and economies at scale. 



 As such, cloud computing is simply the act of storing and processing your data somewhere “in the cloud” rather than on your local server. On the one hand, it offers huge advantages, because you don’t need to buy expensive hardware, hire more 





 team members to operate it, or worry about possible damages or problems like electrical outage. On the other hand, your data is stored somewhere else, and the value of the data is a key factor: Is it going to be secure?  



Leading cloud services providers like Google, Microsoft and Amazon say yes. These tech giants assure clients that they provide a highly secure environment by offering a set of policies, technologies, and controls to strengthen their security. 



 The cloud service market offers various options and continual security improvements to meet the needs of a wide audience. To avoid any confusion about these services, we're going to analyzethem all.  









Benefits of Cloud Computing for Every Company 



By gathering all our expertise in the field and years of successful experience, we've made a list of top-10 main advantages of cloud computing.



Business Benefits of Cloud Computing



I Simplified Service Maintenance 



If you have a remote server, you have to look after it. Every time there is a small issue, you have to ask the tech department's help. The tech department is usually extremely busy with other tasks, so you have two scenarios: they will fix the problem much later, or they will not bother to fix things until it is a bigger issue that affects everyone.



When you use a cloud platform, the company that runs your server has only one objective: to run and maintain the server. So, if any issue arises, they will start working on it immediately. Therefore, you will get your bugs fixed quickly, and you will not have to wait for a small bug to turn into a major one that will require more effort and money.



II Easy Application Integration



You do not need to manually integrate new software as it was necessary with on-premises software. With cloud computing, the integration is easy thanks to the extensive support from cloud vendors like Microsoft with Microsoft Azure and Amazon with AWS. However, keep in mind that you would need to retrain your tech team so they can effectively maintain the system. 



On the one hand, it offers huge advantages because you don’t need to buy expensive hardware, hire more team members to operate it or worry about any possible physical damages or problems like an electrical outage. On the other hand, your data is stored somewhere else, and the value of the data is a key factor: Is it going to be secure? 



Leading cloud services providers like Google, Microsoft, and Amazon say yes. These tech giants assure clients that they provide a highly secure environment by offering a set of policies, technologies, and controls to strengthen their security. 



Financial Benefits of Cloud Computing



III Minimized Investments 



The economic or cost benefits of cloud computing are the main reason why so many businesses choose this approach. We have already mentioned that you do not have to fix big issues that cost a lot of money and requires the tech department to step away from their more important tasks. However, there is more to that.

You can also have an easier start if you are new to the industry or the owner of a small business. You do not have to pay for the server start or the tech team who can run it. 



IV Go Green 



Cloud servers help decrease the carbon footprint since businesses do not need data centers, and increased collaborations online do not require printouts. This is not only good for the environment but also your wallet. 



According to Microsoft, cloud storage is 79-93% more energy efficient compared to traditional storage. And having some underwater datacenters, Microsoft finds them reliable, practical, and energy-efficient. 



Security Benefits of Cloud Computing 



V Improved Safety



There are a lot of physical issues that can happen to your storage: there can be a natural disaster, power outage, or a fatal computer malfunction.Cloud storage providers use back-ups on additional remote servers and perform a security check much more often. So, your files are safer than they could ever be on a local server, contrary to popular belief that cloud storage is riskier.



VI Critical Documents Under Control



With local servers, you can never know who has the document and what they will do with it. Cloud computing allows you to control access to documents with sensitive data and see how and when the document was changed and by whom. You will not have to forward countless versions of the same document: shared editing allows you to have just one.



Keeping the information in the cloud has various benefits for the healthcare industry. It allows for greater reach, especially during a disaster. Medical professionals can consult with each other, keep each other updated on the disaster victim’s condition, or send additional resources requests. Such quick access to data offered by cloud computing can impact the victim’s life.



VII Software Updates Are Automatic



Maintaining a local server requires regular checks and updates. Thus tech team needs to devote time and effort to perform these tasks manually. Cloud storage providers save your company’s time and money by updating the software and security measures themselves.



Benefits of Virtualization in Cloud Computing 



VIII More Space for Collaborations



Cloud computing means stress-free file sharing and editing in real-time. There is no need to send numerous emails or set frequent meetings. One of the main cloud computing benefits that affect all the aspects of the business is that employees from all over the world can collaborate very easily and efficiently.



In times of COVID-19, most businesses have switched to a remote work model, and this tendency would only grow in the coming years because of cloud computing and the numerous benefits it brings.



IX No Need to Stress Over Forgetting Files 



It happened to all of us: you come home and realize that you forgot a flash drive with an important file at the office. Cloud computing easily solves this problem: as soon as you have access to the Internet, you can go to your work documents from anywhere.



This is a great advantage for the retail industry, as retailers can have an enterprise-wide supply chain visibility with cloud computing. With the cloud, retailers can set a chain system to monitor and notify them about stock-outs, expedited deliveries, or high inventories. Cloud also helps capture the status of consignments in real-time that can help retailers make better business decisions.



X Better Work/Life Balance for Employees



While one can work from anywhere with cloud computing, employees will be able to work from home and spend time with family. Moreover, they will also spend less time on collaborations. It is one of the best advantages of cloud computing, according to employees. Providing new technology and services to alleviate the stress that employees may feel will result in happier employees, and according to a study conducted in 2019, happy employees are 13% more productive than unhappy ones. 



The cloud service market offers numerous benefits (we have gone through only the key benefits of cloud computing) and continual security improvements to meet the needs of a wide audience. To avoid any confusion about these services, we are going to analyze and break them down below. 



How to choose a software development company to reap all of these benefits? 10 Questions to Validate Your Application Modernization Vendor Before Starting the Cloud Migration Process 



How Can You Apply Cloud Computing?



Cloud computing incorporates three models: IaaS, PaaS and SaaS. 



IaaS 



 Infrastructure as a service, or IaaS, is the most basic category of cloud computing services. In IaaS you simply rent IT infrastructure including networks, data storage, servers and virtual machines, so that you gain access to a virtual environment where your team can develop solutions on a pay-as-you-go basis. This model is mostly used by companies striving to build software solutions from the ground up, and who want control over almost every infrastructure element. At the same time, the higher control level requires higher responsibilities, like having enough skilled professionals to orchestrate services. Research results from Oracle show that two-thirds of IaaS users believe the model simplifies innovations, cuts new app deployment terms, and decreases ongoing maintenance costs. Even so, 50 percent of respondents said IaaS is not fully secure when it comes to critically valuable data. 



PaaS 



Platform as a service, or PaaS, is used by software development engineers as a closed-environment laboratory for application development and testing. PaaS is the next stage up from the SaaS model; in addition to virtual servers, storage, and networking it includes middleware, operating systems, database management, and other tools needed for development.The difference between IaaS and PaaS models is small, so in most cases companies use them in combination. "Demand for integrated IaaS and PaaS offerings is driving the next wave of cloud infrastructure adoption," said Sid Nag, research director at Gartner, in a 2018 press release. 



SaaS 



Software as a service, or SaaS, is an approach for delivering applications that are accessible through a web browser or are lightweight. Such apps are also referred to as "on demand" and are provided on a subscription basis. In SaaS, the cloud provider fully ensures the hosting and maintenance of the application and its underlying infrastructure, including software upgrades and security patching. Some common examples are Google’s suite of apps (Google Drive, Gmail) and Salesforce CRM.According to International Data Group 89 percent of companies use SaaS, and its popularity is constantly rising. Many businesses develop software products to diversify potential risks and yield an additional revenue channel, offering them as SaaS products. It's vital here to find a hidden pain point that can be addressed with your application — something that’s easier said than done.



Together, these three models can be visualized as a pyramid, with IaaS at the bottom level, PaaS as the next stage up, and SaaS as the most advanced level of cloud services. 







Three Cloud Types You Should Be Aware Of





 Along with the three cloud computing models, there are also three cloud types.  



A Public Cloud 



The first and most common type is a public cloud. Public clouds can be accessed from anywhere through the internet, there's no need to maintain hardware, and they can be deployed fast. Users can choose from a vast number of public cloud providers who earn revenue for consumed bandwidth, storage volume, or CPU (central processing unit, where most system calculations take place) cycles. 



The biggest issue with using a public cloud is security, as the same infrastructure is exploited by other companies, not just yours. Even so, correctly implemented integration with a public cloud can be just as secure as the most carefully managed private cloud, if your cloud provider applies state-of-the-art security methods like intrusion detection and prevention systems (IDPS). When searching for a suitable provider, make sure to review its security measures thoroughly. If you still don’t want to share data centers with other users, you can opt to work with a private cloud instead.





A Private Cloud 



The second type of cloud is a private cloud. These clouds are designed for a single organization, and they're far more secure than the public cloud. Nonetheless, increased security translates into additional costs, as only the world's top companies can yield the same economies of scale as giants like Microsoft or Google. For this reason, mid-level businesses should never build their own cloud if there is no real necessity to do it. Besides, not all of the data or projects from a given company requires high-level protection, so you can use both private and public solutions, choosing a hybrid cloud.



A Hybrid Cloud 



The third type of cloud is a hybrid cloud, which combines private and public cloud solutions. In hybrid clouds, some data is placed in the public cloud, while other projects or applications are kept in the private cloud just like with a mainframe hybrid cloud. Research by TechRepublic shows the main reasons companies choose the hybrid cloud option are disaster recovery planning and to bypass hardware costs while expanding an existing data center. Apple, for example, uses private infrastructure for computing and energy, but also uses public cloud services provided by Microsoft, AWS, and Google.









What Is the Most Popular Type of Cloud Solution?



How popular is each type of cloud solution?







According to statistics provided by RightScale, on average companies run 38 percent of their workloads in public clouds and 41 percent in private clouds. Statistics differ by company size. For example, enterprises use private clouds rather than public (46 percent vs. 33 percent), while small and medium businesses mostly use the public cloud (43 percent) and rarely subscribe to expensive private solutions.

However, public cloud spending is increasing for both enterprises and small to medium businesses, while public cloud spending is growing three times faster than private cloud usage.



Conclusion 



Modern problems require modern solutions, and that is why the number of companies who decide to migrate to the cloud is growing exponentially. Hopefully, after reading the article, you can better understand the various benefits of cloud computing for business.

### Should You Rehost, Rebuild, or Rewrite a Legacy Application With Latest Software?

Let’s return to the 2000s, when you first developed a software platform that allowed your company to thrive for years. As the days went by, it grew to become an integral part of your business, so the number of operations it was needed for grew, too. As a result, the system ballooned in complexity; nearly two decades later, it is a labyrinth of tightly coupled services that needs to be modernized if you’re going to stay competitive and keep pace with technology. Thus, you are standing at the crossroads, considering various modernization options and trying to choose the most efficient. How can you save your platform’s value and make it more modern without spending all your precious resources? Let’s find out.



The process of modernization can include various options that match different business goals. The most common of these options are rehosting, rewriting, and rebuilding. Each option varies in its speed of implementation and affordability. For example, rehosting is the fastest and the most affordable way to resolve a legacy software issue, but it can be applied only if the system was built consistently. Otherwise, you’ll have to modernize through a more complex option or even invest in full-system rebuilding.



Aiming to aid your decision-making process, we wrote this article to help you understand each of these modernization options and determine which one is right for you. First, let’s define what each of these terms means and talk about some situations where you might need them.



The Difference Between Rehosting, Rewriting, and Rebuilding



OK, we’re at the crossroads now, and there are three paths we can choose from. They all lead to the same destination — your brand-new system, which is highly maintainable and ready for integration. They just get there in a different way. Now we are going to see what awaits us on each of these paths.



Legacy Software Rehosting





In simple terms, legacy software rehosting, also known as lift-and-shift, is a process of moving a legacy software application to a different platform, avoiding significant changes. This approach solves the issue of expensive maintenance by moving the system from its legacy hardware to modern hosting solutions. 



 However, in most cases, it is a “stop-gap” option until a new application is developed. Otherwise, it can be the first step toward application rebuilding, as developers can use some of the old parts once the app is placed on the modern platform. 



An outdated software system can be rehosted both to virtual machines and new hardware. If you’re migrating the legacy software to virtual machines, the investment is low, so combined with the high success rate and immediate implementation, this optionis really attractive.  





Besides, the working environment stays the same, and you don’t need to retrain the people who use it. By choosing to rehost legacy software on virtual machines, companies can decrease software maintenance budgets and gain time to prepare for further system improvements. 



If for some reason your data needs to be hosted on-premises, you can move from the old mainframes to more modern hardware. This can resolve the issue of low performance as well as expensive maintenance without changing employees’ working environment. 



However, in such cases, the software will remain the same, so you can apply this technique only if the system software itself is quite modern. Don’t forget that purchasing new hardware automatically increases the project budget.  





Software Rehosting Process Involves











When to Use Legacy Software Rehosting



Legacy software rehosting can be an optimal solution, if:  




affordable price is your priority when it comes to legacy software modernization; 



you need to reduce on-premises infrastructure costs right away;  



your server was damaged due to bugs or natural disasters, and you need your applications up now, so you decide to move your software to a modern hosting solution.

Advantages of Legacy Software Rehosting



The task here is to create an environment equivalent to the original source environment. Digging deeper into the topic, let’s see what application rehosting can bring to your business in practice:



1. No recertification or employee retraining



The system is moved unchanged to the new environment, so you can avoid additional checks and learning.



2. Higher performance plus lower maintenance costs



Rehosting speeds up the application and decreases the maintenance budget by using a pay-as-you-go payment model. 



3. The risk of a system disaster tends to zero



Moved to the modern platform-as-a-service (PaaS) platforms, a legacy software system is unlikely to crash, especially if it is hosted on a virtual machine provided by Microsoft or Amazon.



Disadvantages of Legacy Software Rehosting



The main disadvantage of rehosting is that this simple approach can’t resolve a complicated case. Therefore, rehosting is mostly used as one of the first steps in the modernization process, and companies subsequently move on to legacy software rewriting or rebuilding.



What are the general advantages and disadvantages of legacy systems? Advantages and Disadvantages of Legacy Systems. What to Choose — to Maintain or to Modernize? 



Legacy Software Rewriting




“Rewriting a business application is as arduous as the old process of republishing a manuscript, if not more so.”
TMAXSOFT COMPANY





Legacy software rewriting is redoing the app's code from scratch.



Rewriting legacy software is far more complex than simply rehosting it, as the development team must interpret the existing app’s logic first. Therefore, there is a need to analyze business processes properly that requires active client participation. 



Trying to figure out the architecture of an existing app is not so easy, and trying to understand what is inside a legacy app is far more complicated, as it has often been changing for years without anyone documenting a legacy codebase. 



As a result, we typically encounter a tangled piece of software with no idea of the consequences we might face after changing any part of the application. 





"According to both Standish Group and Gartner reports, more than 70 percent of legacy application rewrites are not successful. 



The most well-known case is the rewriting of the old payroll system for Queensland Health in Australia by IBM. The project, estimated at $6 million, failed when it was rolled out, leading to absolute chaos in payments. In the end, the Queensland government spent $1.2 billion to fix the situation." 



 Just think about it: 70 percent, or approximately two out of every three rewriting projects fail. Why?  First, source code translation is often done by hand, as we replace or add some features.   





Second, apart from code, a team also must translate databases and data. Add one more challenge with differences in hardware and operating systems and we have an answer.   



Plus, enterprises usually have several applications connected with each other, so rewriting them all can take years. It sounds like a trailer to the next Mission: Impossible movie. 



Well, all jokes aside, software modernization problems are quite common. Read here to learn more: 3 Common Mistakes in Legacy Software Modernization 



However, let’s remember that 30 percent of rewriting projects are successful. When it works, rewriting legacy software can transform your business. Let’s learn more about the wonders rewriting can do.



Software Rewrite Process Involves











The approach involves making changes in software specifications, so before starting to rewrite the application, development teams should define the purpose of the business process within the organization and the application itself. Then, they identify human activities within the legacy system and operations outside it to insert them into the process (in other words, features to add). At the next stage, engineers streamline automated and human activities inside the app by user roles and validate the model we’ve got. Depending on its results, the model will be improved and verified again and again until it is ready for implementation.



Reasons to Start a Legacy Software Rewrite Process



There are a few reasons why companies decide to take a risk and start the complex rewriting process:



1. The possibility of making changes and adding needed features



This modernization approach allows them to both save their software core value and increase it by extension of app functionality.



2. Resolving performance, high maintenance costs, and inconsistent code issues



Apart from increasing software productivity, rewriting allows you to fix the so-called technical debt, while Stripe and Evans's Poll research shows maintenance of legacy systems and tech debt is the biggest hindrance to developer productivity (42 percent of developer time is spent on it).



3. The opportunity to revise the business process and its efficiency 



As you already know, rewriting the legacy system first entails a detailed business process analysis and definition of tasks outside the software system. In this way, you can detect some inconsistencies and make needed improvements.



Advantages of Legacy Software Rewriting and Possible Risks   



Rewriting legacy software is a complex process where the development team needs to learn and understand the outdated software first and then create a completely new code that would better satisfy the users’ goals. Although the process takes a lot of time and effort, it has various advantages that we would like to cover.



1. Avoid the Limitations of Legacy System  



You can start everything from scratch without the limitations of the previous systems.   



2. Lift the Restrictions of the Aging Inflexible Solutions 



Aging solutions don't allow much flexibility, so changing the system to satisfy your business's new requirements is almost impossible. Rewriting the legacy software would help you create a dynamic solution that would become a great asset to your business model.



3. Future-Proof Solution to Fit in Modern Requirements  



Utilizing all the benefits of modern programming languages would simplify the integration of new features in the future and allow more flexibility in a fast-changing business environment. According to recent findings, 30 lines of Java can perform the same operations as 600 lines of COBOL code. Just imagine the advantages of updating the old software will bring.



Disadvantages of Legacy Software Rewriting



The most considerable disadvantage of this approach is its complexity, when the chances of data loss, errors, cost overruns, and extensive delays are high, and one bug in code can lead to a catastrophe.



Our cases studies prove that software rewriting can pay off. 3 Legacy Software Modernization Case Studies and 12 Lessons We’ve Learned 



Today, the chances of a rewriting project being successful are far higher than it was even five years ago because of tangible progress in technologies, moving from monolithic web applications to microservices in the same way we are using the cloud instead of on-prem. We are convinced that in this next decade, rewriting will become far easier for companies to apply.



VIEW CASE STUDY







Despite the mentioned positive improvements in rewriting outcomes, rewriting legacy software is still a risky option, as sometimes a new system can’t fully replace the old one because of gaps in the planning stage. Thus, companies are sometimes forced to run two systems in parallel, which is entirely ineffective, especially after performing an expensive modernization project. Does this mean it’s better to invest a little bit more and turn to the rebuild option? Let’s find out.



Legacy Software Rebuilding





We’ve all noticed that the number of innovations in the world is constantly increasing, so it feels like the planet is turning faster today than it was just 20 years ago. This leads to dramatic changes in the business environment, bringing both new opportunities and new threats. 



If your competitors apply those new practices, legacy software can become a vulnerability even though it was a strength just a few years ago. Rehosting and rewriting simply won’t harmonize the outdated system with new requirements, but rebuilding will.  



Legacy software rebuilding is reconstructing the app's components to improve the existing solution.



First, you need to assess the gap between the tasks your application can perform versus what you need to complete now and in the future.





Depending on this gap, you may need to apply a complete or partial rebuild.  



Sometimes it’s worthwhile to rebuild a software system from the ground up, though it involves a substantial upfront investment. Full rebuilding allows you to tailor the system to the new requirements, making solid improvements and yielding all benefits of custom software development.  



If most of the legacy system components are still useful, you can rebuild them partially and save on the project budget. In this case, a development team saves the most valuable parts and integrates new components into them. It’s like replacing broken parts in your car — you won’t replace the whole car if you only need a new transmission, right?





Software Rebuild Process Involves











The rebuilding process means a complex process of rethinking business specifications and changing the system logic configurations. However, business requirements remain the same — if they didn’t, it would be better to replace the system with a totally new one. Thus, we have a challenge here: we must considerably change the system, but keep it in conformity with the old business requirements.



Reasons to Start a Software Rebuild Process



There are three main reasons to get a challenging rebuilding project started:



1. The ability to fully rethink your business model and adjust operations



Changes involving business specification levels lead to changes in the application logic. It gives you an excellent chance to adapt to a new business environment and gain an advantage over rivals whose main advantage is, for instance, an innovative approach.



2. You can start from the very beginning and avoid old tech pitfalls



You may have some considerable inconsistencies in your application technology that can’t be fixed by rewriting. Rebuilding allows you to reorganize the application, changing the way it processes data, its codebase, and its infrastructure as a whole.



3. Even though you rebuilt from scratch, the system value remains the same



This is the main difference between rebuilding and developing an entirely new software: the application essence stays the same. If possible, the development team even saves the previous user experience to simplify a shift to a new system for users.



Here's what you should know about user experience in legacy apps. Risks and Approaches of Legacy Application UI and UX Modernization 



Advantages of Legacy Software Rebuilding and Possible Risks



Legacy software rebuilding is a risky and timely process that allows you to upgrade your software to make it stand out among competitors, and here are some of its main advantages.



1. Improved User Experience



Before the rebuilding process, it’s worth analyzing how users behave on your software and how you want them to act, as you have a great opportunity to enhance user experience.



2. Previous Failures Help You Create a Better Code



After gaining knowledge of what has worked well in your legacy software and what has not worked, your development team has the chance to create a clear and refined code.



3. You Can Adjust Your Business Processes



Rebuilding legacy software allows you to create a completely new and modern technical side of a product and completely modernizes all business processes.



Disadvantages of Legacy Software Rebuilding



Of course, there are some disadvantages to rebuilding legacy software. First, it’s expensive, and most investments should be laid down at the very beginning. Second, it is risky — the more you change, the higher the possibility it won’t work in the end as it used to. But despite these drawbacks, rebuilding can be the most suitable path, so that investment and risk are justified. The main thing here is to determine whether this option is the right fit for you or not.



How to Make a Correct Choice: ModLogix Way



When you're standing at this crossroads with three possible paths to modernize your legacy software, it's important to understand when each approach is being used and which advantages it has. However, it's not enough to understand all the principles of software modernization, as making the right decision would be very hard without previous experience in the field. That is why it's better to work with experts, like the ModLogix team, who have been working on various legacy system modernization cases for many years and understand all the potential pitfalls, and know how to avoid them.





The ModLogix team has developed its own professional legacy software audit and assessment process that helps us analyze the software's current state, file a detailed report, make a list of needed improvements and prioritize the modernization direction.





Only after gaining a clear understanding of the software system condition, the decision between rebuilding, rehosting, and rewriting can be made.





When We Consider Rehosting



If for any reason, you must change the way the application is hosted, and it was built thoroughly, you are lucky and can simply shift programs and data to open systems. It is important to pay attention to the program quality at its creation stage because thorough app architecture and existing code consistency matter when modernizing. Otherwise, you'll have to invest more time and resources to renew the system.



When We Consider Rebuilding



If your business processes have changed, and your current system doesn't satisfy their requirements, rebuilding would be the best option here. It helps you alter system architecture, transform how it processes data, and make significant enhancements. So, you get a partially or fully rebuilt software that now helps to meet the business goals.



When to Rewrite Software



Should you rewrite the software? If the main purpose is to make the system more flexible and get rid of "spaghetti-code," it might be worth considering rewriting the legacy application with modern software. Rewriting legacy applications with the latest software helps improve the system's technical side and make it future-proof, so you can easily add new features and update them when needed. 



Such an approach doesn't require as much time and money as rebuilding, bringing some unexpected results, and is much more flexible than rehosting.











Before starting any legacy software updating processes, the ModLogix team conducts an in-depth analysis of the project's technical base, performance, and business processes. Every case is unique and requires an individual approach.

Our Experience 



One of our clients has a scalable clinical trial database registry with a mission to help pharma companies avoid duplicate subjects and protocol violations during the process of testing new medicines. The platform was written on WebForms in 2009, which now significantly restricted its performance, so the client wanted to move the system to Microsoft Azure.



During the modernization process, the ModLogix team figured out that the MS SQL database was not compatible with Azure MS SQL because of the special stored procs. Azure cloud is operating used the UTC time zone, while their system was working only with EST. Such an incompatibility was causing problems with making records. So we decided to rewrite 140 stored procs in DB and source code on the website to use EST time.

After the rewrite was completed, the system was saving records correctly, and we’ve been able to continue moving to the cloud. Read the full case study here. 



The Bottom Line



In this article, we have talked about a lot of seemingly contradictory information that just goes to show that choosing a suitable modernization type for your legacy software is extremely challenging. That’s why it’s so useful to learn more about the available options — it will simplify any future interactions with software development vendors.



It’s always better to prepare first. Think about the industry you operate in. Has it changed during the last decade? Have those changes affected your business in a way that required you to adjust? Are you aware of new developments or innovative startups blowing up the whole business vertical? The answers to these questions will help you to define your current position and the gap between it and your aim — the system being a driving force of your business again.



We are sure you have people in your company who can catalyze the system modernization process. Involve management, IT, business, and other stakeholders to define business domains, bounded contexts, entities, value objects, and so on. Engaging employees into the process helps to create a system that works for the team, rather than vice versa. 



Modernizing your legacy software isn’t easy but it’s essential. Get ready to start on a complicated journey, leading to the crossroads where you can choose the path that best fits your needs. It doesn’t matter which modernization option you apply. Anything is better than standing and waiting till your innovative competitors displace you on the market.

### 5 Telltale Signs That Shows it's Time for Software Modernization

On average, the life cycle of a software system is approximately five years, which means that when a system has been in place for six, your business is in danger. Of course, if you conduct proper maintenance an application may perform well for longer, but you'll have to be ready to act fast when the system inevitably crashes at the worst possible moment. This is especially true when we talk about businesses with a long-established market whose dependence on the software is enormous and whose software was created years ago, drawing near to or even past its end-of-life date.



There are many compelling reasons that prevent companies from replacing an outdated system or modernizing it, such as the inability to disrupt business processes and the general complexity of modernization. However, let’s be honest with ourselves — legacy software issues can’t be ignored, as doing so is a one-way ticket to catastrophe. 



Company stakeholders can moderate such situations or even prevent them from occurring in the first place. The only thing that needs to be done is to keep a finger on the pulse of the company's software at all times. In this article we are going to reveal the threats inherent in using outdated technologies and show you five signs that indicate the need to plan software modernization or replacement immediately in order to save your business from unexpected crashes that can cause major damage.



Signs That Show It’s Time for Software Modernization



1. The maintenance costs surpass the benefits of the software



Research by Spiceworks highlights the fact that IT budgets are growing year over year, while some organizations spend a shocking 70 to 90 percent of their IT budget on operating and maintaining outdated software. Therefore, while spending for support of end-of-life software is increasing, the software's business value is decreasing, and there will come a time when costs surpass the system's value. If you have crossed this line, you're throwing money down the drain. That means it's necessary to make a choice: to continue investing in outdated legacy software, or to gain additional business strengths by investing in horizontal and vertical expansion, personnel training, R&D and so on.

2. Functionality gaps



Is your business the same today as it was 20 years ago? We are 99 percent sure it has changed, but the software often stays the same. If this is the case for your business, it's likely that just a few crucial features are still topical for you, while the majority are no longer needed. Along with this, you may require additional features and use SaaS, so software costs are higher than they should be. As a result, functionality gaps negatively impact costs, productivity and the overall user experience.

3. Performance issues



Usually, most companies can survive having five minutes of downtime per year, which means that they must deal with any outage immediately so that their customers stay unaware. Disruptions and outages are often unexpected, and they tend to result in the loss of customers. A survey conducted by Acronis indicated that system downtime costs affected businesses US$366,363 each year. If you have faced such issues at least once, add this amount to the maintenance costs you incur for running your outdated software. 



4. Zero mobility



Today, the variety of gadgets available to us is impressive. While 10 years ago people mostly used personal computers or laptops, today they'd rather trust a tablet, a smartphone or even a smartwatch to use any needed applications. Nonetheless, many legacy software systems can be accessed only through the mainframes within offices. It's highly secure, but at the same time it's highly inconvenient. Such systems make remote work impossible, not to mention using mobile and tablet features. Therefore, a lack of mobility means losing many opportunities, and you cannot afford to ignore the significant impact of mobile, both today and in the future.



 5. Security threats 



According to an Accenture Security Report, legacy software is one of the biggest threats to cyber security today. The problem is that software with old encryption algorithms can’t receive security patches, which exposes businesses’ data to multiple risks. Furthermore, old systems lack the ability to produce complicated safe passwords possible through modern technology, as the way they are generated has considerably changed. Nobody wants to discover their system was hacked, so security is one of the strongest reasons that companies switch to modern technologies. Otherwise, regulatory compliance is another key issue that forces some industry representatives to modernize their software.

The Bottom Line



Outdated software poses a major threat to any company that uses it. However, while for one business it can be a low, controlled risk, for another it can be a disaster, causing large-scale damages and loss of reputation. Being in the first group means being aware of your software system's current state and carefully planning its modernization process to avoid downtimes and their negative effects.



Gartner predicts that by 2023, 90 percent of enterprise applications in use today will still be in use. We can’t even imagine how many companies use old systems, and most of them are doing OK. Perhaps they're not so modern and efficient, but the systems work well enough. Despite this, we must understand that legacy software performs become less efficient over time, with every new operation.



We have outlined the main reasons companies continue using the same outdated software and revealed five signs that show when it's necessary to modernize immediately. Of course, you may come across roadblocks or burdens that prevent you from replacing or modernizing your business system, but it's imperative to understand that this issue can’t simply resolve itself. You need to act. Take some inspiration from Steve Jobs and Bill Gates, who maybe felt fear deeply in their souls but never allowed it to stop them.

### 3 Common Mistakes in Legacy Software Modernization

1. Big Bang Deployment 



Let’s imagine your outdated software in use is an airplane in flight. Will you change a vital part of it right in the sky? We’re pretty sure this isn’t the greatest idea. 



Because they’re aiming to get benefits from the modernized application as soon as possible, many companies immediately replace an old system with a new one and ... watch it crash and burn. That’s why we suggest that clients keep the old system and run a new one in parallel until it is fully debugged and adjusted. Only when the relevance of the new app is proved during trials should you fully migrate to it. Furthermore, the Strangler Pattern Approach even allows you to build a new system around an existing one and incrementally migrate functionality.



 “We were lucky that we started the rebuild process early, before we faced a crisis with the existing platform. This meant we were able to rely on the existing product while developing the new one. It gave us time to prove what could be built using the new technologies, rather than having to demonstrate immediate returns. It allowed us to put off migration and integration questions. It gave us the ability to test and compare the new systems and validate the improvements we were seeking.” MATT GREEN, PRODUCT MANAGER AT HINDAWI 



2. Building the Software First and Trying to Move Data Afterward



Data is the biggest asset of any legacy application, and usually the necessity to save data is the primary argument for modernization instead of replacing. The research by McKinsey Global Institute highlights that data-driven companies are 23 times more likely to get customers, six times more likely to retain them, and 19 times more profitable. Inspiring statistics, don’t you think?



However, sometimes companies overlook this factor and build software first, then try to squeeze data into the new app when it is ready. Such an approach frequently leads to a huge data conversion mess, so there is a risk of a new software launch failure. To avoid such consequences, it’s better to focus on current data structure while building a new system. Remember, data is a core of the whole system.



3.  Removing Spare Features 



Enterprise software usually consists of a few distinct apps with a great number of little features, so it is very unlikely one individual stakeholder is aware of all of them. Thus, you can assume some of them are not necessary, but don’t hurry to remove spare functionality. While a particular feature may be irrelevant for one department, it easily could be crucial for another. Imagine how unpleasant it would be to discover missing functionality after the modernized system launch.



How to insert only the necessary features into the application? Start from the redesign of legacy UI/UX. Risks and Approaches of Legacy Application UI and UX Modernization 



Of course, rudimentary features arise from time to time, and it is better to eliminate them to decongest the system. However, it doesn’t mean you have to eliminate every feature you assume is not relevant. Consider users first. Think about every employee who uses the application, as its convenience directly influences their productivity.
