Migration Coordination
Database Migrations
Rollback Strategy
Coordination Dependencies
- Migration order: 1 → 2 → 3 (sequential due to dependencies)
- Feature activation: Features activated after successful migration
- Monitoring: Extended monitoring during migration window
Staged Rollout Plan
Phase 1: Canary (5% of traffic)
- Duration: 2 hours
- Monitoring: Error rate < 0.1%, Latency < 200ms
- Auto-abort threshold: Error rate > 1% OR Latency > 500ms
- Success criteria: Zero critical errors, performance within baseline
Phase 2: Gradual Rollout (25% of traffic)
- Duration: 4 hours
- Monitoring: Error rate < 0.2%, Latency < 250ms
- Auto-abort threshold: Error rate > 2% OR Latency > 600ms
- Success criteria: No regression in key metrics
Phase 3: Full Rollout (100% of traffic)
- Duration: Continuous
- Monitoring: Error rate < 0.5%, Latency < 300ms
- Manual rollback trigger: Error rate > 5% OR Latency > 1000ms
- Success criteria: Stable performance for 24 hours
Rollout Gates
- Gate 1: Canary success (5% traffic, 2 hours)
- Gate 2: Gradual rollout success (25% traffic, 4 hours)
- Gate 3: Full rollout approval (100% traffic)
Auto-Abort Rules
- Error rate: > 1% during canary, > 2% during gradual
- Latency: > 500ms during canary, > 600ms during gradual
- Critical errors: Any critical error during canary phase
- Business metrics: > 10% drop in conversion rate
Release Rollback Plan
Rollback Mechanism
- Feature flags: Disable features via configuration
- Database rollback: Execute rollback migration scripts
- Code rollback: Revert to previous deployment
- Configuration rollback: Revert configuration changes
Rollback Triggers
- Automatic: Error rate > 5%, Latency > 1000ms, Critical errors
- Manual: Release owner decision, stakeholder request
- Time-based: Rollout gates not met within expected time
Responsible Teams
- Primary: @alice (Release Owner)
- Secondary: @bob (Database Team)
- Escalation: @charlie (Engineering Manager)
- Communication: @diana (Product Manager)
Estimated Rollback Time
- Feature flag disable: 2 minutes
- Database rollback: 15 minutes
- Full code rollback: 30 minutes
- Total estimated time: 30 minutes
Rollback Communication
- Slack: #engineering-alerts, #product-updates
- Email: engineering@company.com, product@company.com
- Status page: Update company status page
- Customer communication: Prepare customer notification
Observability & Monitoring
Dashboards
Alerts
- Error rate alert: > 1% error rate for 5 minutes
- Latency alert: > 500ms average latency for 5 minutes
- Critical error alert: Any critical error immediately
- Business metric alert: > 10% drop in conversion rate
Monitoring Duration
- Intensive monitoring: First 24 hours
- Standard monitoring: First 7 days
- Extended monitoring: First 30 days (for high-risk changes)
