Rewrites don't fail because of the new framework. They fail because of everything the old app does that nobody wrote down.
MigrateX moves legacy frontends — Ember, Backbone, Angular, jQuery — to React one feature at a time, while your product keeps shipping.
- 🔍 Map everything first. Every route, service and hidden side effect, before a line is ported.
- 🔀 Ship behind a switch. Each feature can be turned back to the old app instantly.
- ✅ Prove parity. The same tests run on old and new. It goes live only when both pass.
- 🧹 Leave nothing behind. Old code, switches and glue removed. One clean codebase.
No feature freeze. No launch day.
