## Rollback Plan
|
|
|

### Rollback Decision Criteria
|
|
Initiate rollback if any of the following occur:
|
|
- Error rate exceeds [threshold]% for more than [duration] minutes
|
|
- Critical functionality broken (specifically: [list critical features])
|
|
- Performance degradation > [threshold]% from baseline
|
|
- Database corruption or data loss detected
|
|

|
```
|
|
|
|

|
|
# Deploy previous version
|
|
# TODO: Add rollback deployment commands
|
|
```
|
|
|
|
**Verification:**
|
|
- [ ] Previous version deployed
|
|
- [ ] Services healthy
|
|
|
|
#### Step R.3: Revert Database (if needed)

|
|
```
|
|
|
|
**Verification:**
|
|
- [ ] Configuration restored
|
|
- [ ] Services using correct config
|
|
|
|
#### Step R.5: Verify Rollback
|
|
- [ ] System functionality restored
|
|
- [ ] Error rates normalized
|
|
- [ ] No data loss
|
|
- [ ] Users can access application
|
|
|
|
### Post-Rollback Actions
|
|
- [ ] Notify stakeholders of rollback
|
|
- [ ] Document rollback reason
|
|
- [ ] Schedule post-mortem
|
|
- [ ] Update deployment status
|
