01/Pattern
Modernize a legacy platform without stopping the business
- The challenge
- A core system has become slow to change and risky to touch, but the business cannot pause while it is replaced.
- Our approach
- Map the domain, place a facade in front of the legacy system and migrate capabilities one at a time behind it — with tests that prove behavior is preserved at each step.
- Domain mapping
- Incremental migration
- Contract tests
- Observability
