Read example/package.json to identify the current react-native version.
curl -s "https://raw.githubusercontent.com/react-native-community/rn-diff-purge/diffs/diffs/{currentVersion}..{toVersion}.diff" | awk '/^GIT binary patch$/,/^diff --git/ {if (/^diff --git/) print; next} 1'
For binary files (e.g., gradle-wrapper.jar):

If diff returns 404: version combination may not exist in rn-diff-purge; suggest alternative paths or manual migration.
Identify file additions/deletions/modifications, dependency changes, config updates, native code changes (iOS + Android), and breaking changes.
Order: package.json deps -> config files -> code changes -> iOS native -> Android native. Preserve custom modifications in example/.
react - Check: npm view react-native@{version} peerDependencies.reactreact-test-renderer - Must match React version@react-native-community/cli - Check compatibility with RN versioncd example && npm install
For iOS:
cd example/ios && pod install
Rebuild native apps from root directory:
npm run build:ios
npm run build:android
