React Native New Architecture Migration

React Native's New Architecture — the Fabric renderer and Turbo Modules — is no longer optional. It has been the default since React Native 0.76, and old-architecture support ended with React Native 0.82. Apps still pinned to the legacy bridge no longer receive upgrades, security fixes, or support from the library ecosystem.

If your app was built before 2024, some of it almost certainly depends on the old architecture: hand-written native modules, UIManager calls, or third-party libraries frozen years ago. Left alone, that dependency hardens into an app you cannot upgrade.

What we do

Migration audit. We scan your dependency tree against React Native Directory's New Architecture compatibility data and your own native code for bridge-era patterns, and give you a concrete migration map: what works as-is, what needs a version bump, what needs rewriting, and what should be replaced.

The migration itself. We run your app under the New Architecture behind a branch, fix what breaks, convert hand-written native modules to Turbo Modules and custom views to Fabric components, and land the switch without freezing your feature work.

Typical breakages we fix:

• Native modules built on the legacy bridge (NativeModules, RCTEventEmitter patterns)
• Direct UIManager and findNodeHandle usage
• Third-party libraries abandoned before 2024
• Layout and rendering differences under Fabric
• Startup and threading assumptions that no longer hold in bridgeless mode

Why now

Every React Native release since 0.82 ships without the legacy architecture. Each month on the old bridge grows the gap between your app and the ecosystem: new library versions drop old-arch support, OS releases demand newer React Native versions, and the migration only gets bigger.

Most migrations we scope land in weeks, not months — and your team keeps shipping features the whole time.
