How to Use Cursor for Code Migration
Migrate codebases between frameworks, languages, or versions using Cursor. Covers React class → hooks, Python 2 → 3, JavaScript → TypeScript, and API version upgrades.
Implementation Steps
- 1
Assess migration scope
Count files affected, identify patterns to convert, map breaking changes from migration guide.
- 2
Generate migration rules
Create pattern-matching rules: old pattern → new pattern. Test on 5-10 representative files.
- 3
Batch convert with AI
Process files in batches. Verify each batch compiles and passes existing tests before proceeding.
- 4
Handle edge cases manually
AI will flag files it cannot convert confidently. Queue these for manual migration.
- 5
Run full regression suite
After all files converted, run complete test suite. Fix any failures from migration artifacts.
Expected Metrics
Ehsan's Recommendation
Code migration is AI's superpower: repetitive pattern transformation across hundreds of files. Cursor handles the mechanical conversion (class → function, require → import, callback → async/await) perfectly. The 5-15% that needs human attention is genuinely complex — conditional logic that changed semantics between versions. Budget 20% of time for these edge cases; they take 80% of the effort.
