How to Effectively Conduct a Legacy System Integration
What's the best way to integrate your legacy systems? Check 4 basic approaches to revamp your software.
When changes are necessary for modernization, but common development practices are not possible, API-based integration is the solution. It’s the most hands-on approach to connect legacy systems with modern systems and cloud apps. Legacy system integrations via API accelerate digital transformation and enable new business perspectives.
API INTEGRATIONS
BUSINESS FLOW SUFFERS FROM APPLICATION INFLEXIBILITY
YOU HAVE AN EXTENSIVE NETWORK OF DATA SOURCES
THE ORGANIZATION’S DATA IS UNDERUTILIZED
THE SOLUTION REQUIRES COMPLIANCE-SPECIFIC APIS (HIPAA, PCI)
The integration of software components is a low-risk approach to modernizing a legacy system. It facilitates the connection of data inside and outside an organization, which streamlines business processes. There is a couple of scenarios when an API-based approach or web services can be used for systems to communicate.
Before diving into designing and integrating APIs, we identify the business specifics and tech background first. Because old systems are fairly complex, connectivity may require interruptions of core processes. What challenges are we supposed to avoid? Data stored in different sources, data in different formats, lack of standardized and accurate documentation. With that in mind, we use the following approaches to system integration:
We divide the API into a separate layers (cloud-based integration platform, hybrid integration platform, third party API integration) to connect it to the server or database through standard protocols. This way, we don’t violate the solution’s architecture, but expand its functionality and gain real-time data access.
We design custom APIs for solutions with old mainframes that do not support basic protocols. This approach is especially useful to consolidate disparate applications into one system to easily comply with business logic. However, this process requires a competent modernization provider.

LEGACY system’s specific api
As we’ve already established, the data in legacy solutions is siloed and is sometimes unreachable. According to statistics, 97% of a company’s data is never used again. To filter out what’s important and what’s not, and do the upgrade correctly, we suggest these tips:
Clunky architecture could interfere with APIs integration. as previously mentioned. Some COBOL solutions cannot connect via third party REST APIs, and this restricts your business. Look here for the signs that your architecture requires immediate enhancements.
We apply the common API protocols to standardize the data exchange between diverse software systems, such as:
