## Emergency Rollback Plan
|
|
|
|
If critical issues arise during implementation:
|
|
|
|
### ✅ Immediate Rollback Steps
|
|
|
|
1. **Stop New Services**:
|
|
```bash
|
|
docker-compose stop mvp-platform-database mssql-source etl-scheduler
|
|
```
|
|
|
|
2. **Restore Backend Code**:
|
|
```bash
|
|
git checkout HEAD~1 -- backend/src/features/vehicles/
|
|
git checkout HEAD~1 -- backend/src/core/config/
|
|
```
|
|
|
|
3. **Restore Docker Configuration**:
|
|
```bash
|
|
git checkout HEAD~1 -- docker-compose.yml
|
|
git checkout HEAD~1 -- .env.example
|
|
```
|
|
|
|
4. **Restart Application**:
|
|
```bash
|
|
docker-compose restart backend
|
|
```
|
|
|
|
5. **Validate Rollback**:
|
|
```bash
|
|
curl -s http://localhost:3001/api/vehicles/dropdown/makes | jq '. | length'
|
|
```
|
|
|
|
### ✅ Rollback Validation
|
|
|
|
- [ ] **External API Working**: vPIC API endpoints functional
|
|
- [ ] **All Tests Pass**: Original functionality restored
|
|
- [ ] **No Data Loss**: No existing data affected
|
|
- [ ] **Performance Restored**: Response times back to baseline

## Implementation Notes
|
|
|
|
### Dependencies Between Phases
|
|
- **Phase 2** requires **Phase 1** infrastructure
|
|
- **Phase 3** requires **Phase 2** backend changes
|
|
- **Phase 4** requires **Phase 1** infrastructure
|
|
- **Phase 5** requires **Phases 1-4** complete
|
|
|
|
### Critical Success Factors
|
|
1. **Database Connectivity**: All database connections must be stable
|
|
2. **Data Population**: MVP Platform database must have comprehensive data
|
|
3. **Performance Optimization**: Database queries must be optimized for speed
|
|
4. **Error Handling**: Graceful degradation when services unavailable
|
|
5. **Cache Strategy**: Proper caching for performance requirements
