Prompt

I need to upgrade an older React Native application (running v0.74) that relies heavily on prop-types, classic Redux, and legacy architecture to the latest Expo SDK and React Native releases. Please provide a step-by-step migration roadmap detailing how to sequence the version upgrades safely, avoid build breaking points, and select modern package alternatives for state management and internationalization.

React Native Expo (0.76-0.82+ / SDK 52+)

Status: Production Ready Last Updated: 2025-11-22 Dependencies: Node.js 18+, Expo CLI Latest Versions: [email protected], expo@~52.0.0, [email protected]

Quick Start (15 Minutes)

1. Create New Expo Project (RN 0.76+)

# Create new Expo app with React Native 0.76+
npx create-expo-app@latest my-app

cd my-app

# Install latest dependencies
npx expo install react-native@latest expo@latest

Why this matters:

Expo SDK 52+ uses React Native 0.76+ with New Architecture enabled by default
New Architecture is mandatory in React Native 0.82+ (cannot be disabled)
Hermes is the only supported JavaScript engine (JSC removed from Expo Go)

2. Verify New Architecture is Enabled

# Check if New Architecture is enabled (should be true by default)
npx expo config --type introspect | grep newArchEnabled

CRITICAL:

React Native 0.82+ requires New Architecture - legacy architecture completely removed
If migrating from 0.75 or earlier, upgrade to 0.76-0.81 first to use the interop layer
Never try to disable New Architecture in 0.82+ (build will fail)
