### 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.

**Upgrade Complete**: The Garage Web UI has now been successfully upgraded to Garage Admin API v2, providing enhanced functionality and better performance.
