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
