+# Upgrading Expo
+
+## Overview
+
+Upgrade Expo SDK versions safely, handling breaking changes, dependencies, and configuration updates.
+
+## When to Use This Skill
+
+Use this skill when you need to upgrade Expo SDK versions.
+
+Use this skill when:
+- Upgrading to a new Expo SDK version
+- Handling breaking changes between SDK versions
+- Updating dependencies for compatibility
+- Migrating deprecated APIs to new versions
+- Preparing apps for new Expo features
+
+## Instructions
+
+This skill guides you through upgrading Expo SDK versions:
+
+1. **Pre-Upgrade Planning**: Review release notes and breaking changes
+2. **Dependency Updates**: Update packages for SDK compatibility
+3. **Configuration Migration**: Update app.json and configuration files
+4. **Code Updates**: Migrate deprecated APIs to new versions
+5. **Testing**: Verify app functionality after upgrade
+
+## Upgrade Process
+
+### 1. Pre-Upgrade Checklist
+
+- Review Expo SDK release notes
+- Identify breaking changes affecting your app
+- Check compatibility of third-party packages
+- Backup current project state
+- Create a feature branch for the upgrade
+
+### 2. Update Expo SDK
+
+```bash
+# Update Expo CLI
+npm install -g expo-cli@latest
+
+# Upgrade Expo SDK
+npx expo install expo@latest
+
+# Update all Expo packages
+npx expo install --fix
+```
+
+### 3. Handle Breaking Changes
+
+- Review migration guides for breaking changes
+- Update deprecated API calls
+- Modify configuration files as needed
+- Update native dependencies if required
+- Test affected features thoroughly
+
+### 4. Update Dependencies
+
+```bash
+# Check for outdated packages
+npx expo-doctor
+
+# Update packages to compatible versions
+npx expo install --fix
+
+# Verify compatibility
+npx expo-doctor
+```
+
+### 5. Testing
+
+- Test core app functionality
+- Verify native modules work correctly
+- Check for runtime errors
+- Test on both iOS and Android
+- Verify app store builds still work
+
+## Common Issues
+
+### Dependency Conflicts
+
+- Use `expo install` instead of `npm install` for Expo packages
+- Check package compatibility with new SDK version
+- Resolve peer dependency warnings
+
+### Configuration Changes
+
+- Update `app.json` for new SDK requirements
+- Migrate deprecated configuration options
+- Update native configuration files if needed
+
+### Breaking API Changes
+
+- Review API migration guides
+- Update code to use new APIs
+- Test affected features after changes
+
+## Best Practices
