Modernize Your Legacy Frontend Without a Rewrite

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.
