 ## Risk Mitigation
 
 ### **Incremental Migration Strategy**
+
 1. **One file at a time** - Minimize risk of breaking changes
 2. **Comprehensive testing** - Test each migration thoroughly
 3. **Rollback capability** - Keep databaseUtil.ts until migration complete
 4. **Documentation updates** - Update docs as methods are migrated
 
 ### **Testing Strategy**
+
 1. **Unit tests** - Test individual component functionality
 2. **Integration tests** - Test database operations
 3. **End-to-end tests** - Test complete user workflows
 4. **Performance tests** - Ensure no performance regression
 
 ### **Rollback Plan**
+
 1. **Git branches** - Each migration in separate branch
 2. **Backup files** - Keep original files until migration verified
 3. **Feature flags** - Ability to switch back to databaseUtil if needed
