### Upgrade Count

- **Total Endpoints Upgraded**: 18
- **Successfully Upgraded**: 18 (100%)
- **Number of Files Upgraded**: 5 TypeScript hook files

## Backend Compatibility

✅ **No Backend Modifications Required**:

- The backend uses a reverse proxy (`ProxyHandler`) to directly forward API requests to the Garage Admin API.
- All v2 API requests are automatically forwarded to the correct Garage Admin endpoints.
- No changes to the Go backend code were necessary.

## Build Verification

✅ **Build Successful**:

- TypeScript compilation passed.
- Vite bundling was successful.
- No compilation errors.

⚠️ **Code Quality Warnings**:

- ESLint `any` type warnings are present (do not affect functionality).
- It is recommended to optimize type definitions in the future.

## New Feature Availability

After upgrading to the v2 API, the project can now use the following new features:

### Enhanced Cluster Management

- More detailed cluster health status information
- Improved layout management operations
- Better node connection handling

### Enhanced Key Management

- Support for more key types
- Improved permission management
- Better key import/export functionality

### Enhanced Bucket Management

- Richer bucket metadata
- Improved alias management
- Finer-grained permission control

## Next Step Recommendations

1. **Type Definition Optimization**: Replace `any` types with specific interface definitions.
2. **Functional Testing**: Test all upgraded features in a development environment.
3. **Documentation Update**: Update project documentation to reflect the use of the v2 API.
4. **Error Handling**: Adjust error handling logic based on the v2 API's response format.

## Risk Assessment

### Low Risk

- API path upgrade was successful.
- No compilation errors.
- Good backend compatibility.

### Features Requiring Testing

- Actual calls to all upgraded API endpoints.
- Handling of error responses.
- Compatibility of new API parameter formats.

## Rollback Plan

To roll back to the v1 API if necessary:

1. Restore the API paths in all hook files.
2. Ensure the Garage server supports the v1 API.
3. Recompile and redeploy.
