Migration & Refactoring

Systematic approach to complex code migrations with safety guardrails and rollback capabilities.

When to Use

• Dependency upgrades - Major version bumps with breaking changes
• Framework migrations - React class→hooks, Flask→FastAPI, Django→DRF, etc.
• Language modernizations - Python 2→3, JavaScript→TypeScript
• Large-scale refactoring - Cross-file changes requiring consistency
• Database schema evolution - Migrations with data transformation
• Monorepo decomposition - Extracting services from monoliths
