Code Transformation

Perform automated code transformations for migration.

Migration Checklist

Syntax Transformations

• Identify deprecated syntax patterns requiring updates
• Apply language version syntax migrations consistently
• Verify transformed code preserves original semantics
• Check for edge cases missed by automated transforms

API & Import Updates

• Rename changed API calls across the codebase
• Update import paths to reflect new module structure
• Replace removed APIs with recommended alternatives
• Verify no stale imports remain after transformation

Pattern Replacements

• Convert deprecated patterns to idiomatic new patterns
• Replace obsolete utility usage with modern equivalents
• Update error handling to match new conventions
• Transform configuration formats to new schema

Automated Verification

• Run transformed code through type checker and linter
• Verify all codemods are idempotent and safe to re-run
• Check that no unintended changes were introduced
• Validate transformation coverage with before/after diffs
