How we work on legacy code update

When updating legacy code, there are several scenarios we might encounter. In some cases, we will analyze code to understand the logic of products or features, but completely re-write the code. Or we might work with the existing codebase and add features while refactoring the code, step-by-step. In the rarest cases, we just add new features.

Whenever we analyze a codebase, we pay special attention to:

  • The age of third-party apps & libraries, because they affect migration efficiency
  • Architecture, because it affects the update process flow
  • Test coverage
  • Deployment of new code into an existing system

Our Approach

What do we do before updating legacy code?

All legacy code is unique, and so are your business goals and products. That’s why we always begin our legacy codebase updates with a code review to identify what scenario we’re dealing with. We also complete a few core tasks before starting our update, such as:

  • Define the outcomes, so you and our team will be on the same page
  • Develop a transfer flow, so your product will work properly during the update
  • Assess test coverage and write tests, if needed
