Legacy System to API

The system still does its job. Nothing else can talk to it.

Rather than replacing a system that works, we wrap it. A clean API in front of the legacy application lets new products be built immediately, while migration happens gradually or not at all.

This also creates the seam you need later: once callers depend on the API rather than the system, what sits behind it can be replaced piece by piece.

What the work involves

  • API wrappers over legacy databases and applications
  • Abstraction layers that hide internal structure
  • Modern authentication in front of old systems
  • Automated tests around existing behaviour
  • Incremental extraction of services
