Services

Legacy software re-engineering stands as a less risky approach to software rebuilding, but this option still requires thorough preparation and planning. Engineers take a legacy application as a basis to build an up-to-date solution with an identical or even better feature-set. It will seem just the same by functionality, but look and feel like a brand-new modern solution. The process of re-engineering legacy software requires the translation of the source code into another programming language, the reorganization of a database or its transfer, the optimization of software architecture, the addition of new features, and the integration of third-party APIs.

Re-engineering Process

I DON’T KNOW WHETHER MY SYSTEM SHOULD BE
RE-ENGINEERED OR NOT?

Even though re-engineering is a relatively low-risk approach to software modernization, it requires solid development efforts and expertise. Before making any decisions and updating the legacy system, estimate the potential business and technical perspectives of your brand-new software.

General Model for Software Re-engineering

Let’s try to understand what is hidden under the re-engineering in software engineering concept using simple words. We have a legacy system in use with its four constituents: the concept, requirements, design, and implementation.

01

Using the reverse engineering method, the development team analyzes the new solution, including documentation and source code to extract the requirements it was built by and reveal the concept of the app.

02

After that, we can re-think the existing system concept in accordance with current business circumstances and form new requirements for a target system design and implementation.

03

The most difficult stage is completed and now we can
re-engineer legacy software systems using the forward engineering method. When the target system is ready, your provider checks whether the new system matches the old one by functionality quality.

How to Use
Re-engineering Services in a Particular Case?

FROM CASE TO CASE RE-ENGINEERING DIFFERS DEPENDING ON:
  • snowflake The state of your current system
  • snowflake The documentation availability
  • snowflake The consistency of its previous implementation

That’s why the methodology for this approach can be chosen using the scheme shown on the figure below. As you can see, we can avoid the complex reverse engineering stage if your current system implementation was consistent.

A piece of advice

This is one more argument to carefully choose a legacy modernization company who can not only make the system work, but implement it in a technically correct manner. It’s like building a house — if you have any problems in the foundation, it can cause many issues when you try to rebuild it.
