+# Type Migration Plan
+
+**Date**: 2025-01-27  
+**Action**: 1.1.3.2 - Create type migration plan  
+**Status**: ✅ Complete
+
+## Overview
+
+This document lists all files that import manual types (`Track`, `User`, `ApiError`, etc.) from `types/api.ts` and feature-specific type files. These need to be migrated to use generated types from `types/generated/`.
+
+## Generated Types Location
+
+- **Generated Types**: `apps/web/src/types/generated/`
+- **Source**: Generated from `veza-backend-api/openapi.yaml` using `openapi-generator-cli`
+- **Generator**: `typescript-axios`
+
+## Manual Types to Replace
+
+### From `types/api.ts`:
+- `Track` → `VezaBackendApiInternalModelsTrack`
+- `User` → `VezaBackendApiInternalModelsUser`
+- `ApiError` → `InternalHandlersAPIResponse` (error field)
+- `PaginatedResponse<T>` → Keep (utility type, not in OpenAPI)
+- `UserDTO` → `VezaBackendApiInternalDtoUserResponse`
+- `TrackDTO` → `VezaBackendApiInternalModelsTrack`
+
+### From `features/tracks/types/track.ts`:
+- `Track` → `VezaBackendApiInternalModelsTrack`
+- `TrackStatus` → `VezaBackendApiInternalModelsTrackStatus`
+
+### From `features/auth/types/index.ts`:
+- `User` → `VezaBackendApiInternalModelsUser`
+
+## Files Requiring Migration
+
+### Files importing from `types/api`:

+11. `src/features/playlists/pages/PlaylistDetailPage.test.tsx` - Uses `Track`
+
+## Migration Strategy
+
+### Phase 1: Core Types (HIGH PRIORITY)
+1. Replace `ApiError` in error handling utilities
+2. Replace `User` in auth store and services
+3. Replace `Track` in core services
+
+### Phase 2: Feature Types
+1. Replace `Track` in library features
+2. Replace `Track` in playlist features
+3. Replace `User` in profile features
+
+### Phase 3: Component Types
+1. Replace types in React components
+2. Update type guards and utilities
+
+### Phase 4: Test Files
+1. Update test files to use generated types
+2. Update test fixtures
+
+## Type Mapping Reference
+
+```typescript
+// Old imports
+import { Track } from '@/types/api';
+import { User } from '@/types/api';
+import { ApiError } from '@/types/api';
+import { Track } from '@/features/tracks/types/track';
+
+// New imports
+import { VezaBackendApiInternalModelsTrack } from '@/types/generated';
+import { VezaBackendApiInternalModelsUser } from '@/types/generated';
+import { InternalHandlersAPIResponse } from '@/types/generated';
+```
+
+## Notes
+
+- `PaginatedResponse<T>` is a utility type and should be kept (not in OpenAPI spec)
+- Some generated types may have different field names (snake_case vs camelCase)
+- May need type adapters/mappers for compatibility during migration
+- Generated types use longer names - consider creating type aliases
+
+## Validation
+
+After migration:
+- ✅ All TypeScript errors resolved
+- ✅ All tests pass
+- ✅ No runtime errors
+- ✅ Type safety maintained
+
+## Rollback Plan
+
+If migration causes issues:
+1. Revert imports to manual types
+2. Keep generated types directory for reference
+3. Fix OpenAPI spec if types are incorrect
+4. Regenerate types and retry migration
