|
||||
- [ ] **Backup created**: Original component backed up
|
||||
|
||||
### Complexity Assessment
|
||||

|
||||
- [ ] **Medium** (15-25 min): Multiple database operations, several notifications
|
||||

|
||||
|
||||
### Migration Performance

|
||||
|
||||
## 📝 Notes and Special Considerations
|
||||
|
||||
### Special Migration Considerations
|
||||
- Component uses PlatformServiceFactory.getInstance() for platform detection
|
||||
- No database operations to migrate
|
||||
- No notification patterns to migrate
|
||||
- Deep link functionality is critical - must preserve platform detection
|
||||
- Component handles mobile vs desktop platform differences
|
||||
|
||||
### Risk Assessment
|
||||
- Low risk: Simple component with minimal platform service usage
|
||||
- Deep link functionality is critical - must preserve platform detection
|
||||
- Platform service migration is straightforward
|
||||
|
||||
### Testing Strategy
|
||||
- Test deep link redirection on mobile devices
|
||||
- Test web fallback on desktop
|
||||
- Verify platform detection works correctly
|
||||
- Test error handling for failed redirects
|
||||
- Verify cross-platform compatibility
|
||||
|
||||
