- Engagement
- Fixed scope
- Code ownership

The rewrite is the tempting answer and the one that most often ends badly: two systems to maintain, a migration that never finishes, and features frozen for a year.
We strangle instead. Tests around current behaviour first, then route functionality piece by piece to new code, with the old system live until the last piece moves.
What you get
- Characterisation tests around current behaviour before changes
- Incremental strangler migration — the system stays live
- Framework and language version upgrades with a working path
- Dependency and security debt cleared as part of the work
- Knowledge transfer so your team owns the result
