Impact
Services Affected
- Edge department info service
- [List additional services and dependencies]
Technical Considerations
- API compatibility with existing consumers
- Department data accuracy and synchronization
- Performance and response time requirements
- Caching strategy for department information
Data Considerations

- Data consistency across systems
- Data source integration
- Master data management
Implementation Plan
Phase 1: Assessment & Design
- Document current service functionality
- Identify all consumers and integration points
- Evaluate target architecture/platform
- Assess data migration requirements
- Define migration strategy
- Create proof of concept
Phase 2: Development
- Set up new infrastructure
- Implement/migrate core functionality
- Configure API endpoints
- Set up authentication and authorization
- Implement monitoring and logging
- Create comprehensive test suite
Phase 3: Migration
- Deploy to staging environment
- Integration testing with consumers
- Performance and load testing
- Data validation testing
- User acceptance testing
- Security review
- Create rollback procedures
Phase 4: Cutover
- Deploy to production

- Monitor service health and performance
- Update consumer configurations
- Decommission old infrastructure
- Archive legacy documentation
Risks & Mitigation
| Risk | Impact | Mitigation |
|---|---|---|
| Service disruption | High | Gradual cutover with parallel running systems |
| Department data inconsistency | High | Thorough data validation and testing |
| Performance degradation | Medium | Load testing and capacity planning |
| Integration breakage | High | Extensive integration testing before cutover |
| Data source synchronization issues | Medium | Implement robust data sync mechanisms |
