2. Identify breaking changes for target version
3. Map affected files and components
4. Assess test coverage
```

### Step 2: Planning
```
1. Design migration strategy (big bang vs incremental)
2. Create migration phases
3. Identify codemods needed
4. Plan rollback procedures
```

### Step 3: Preparation
```
1. Ensure test coverage
2. Set up CI/CD for migration
3. Create codemods
4. Document changes
```

### Step 4: Execution
```
1. Apply migrations incrementally
2. Run tests after each phase
3. Validate functionality
4. Update documentation
```

### Step 5: Completion
```
1. Clean up deprecated code
2. Final validation
3. Document lessons learned
4. Archive rollback plans
```

## Invocation

### Claude Code / Claude Agent SDK
```bash
use migration-assistant: ANALYZE_MIGRATION React 17 React 18
use migration-assistant: BREAKING_CHANGES Next.js 13 14
use migration-assistant: GENERATE_CODEMODS useState→useReducer
```

### Cursor IDE
```
@migration-assistant ANALYZE_MIGRATION source target
@migration-assistant ROLLBACK_PLAN migration_name
```

### Gemini CLI
