Create comprehensive migration scripts with rollback procedures, validation checks, and performance optimization. ## Use this skill when - Working on sql database migration strategy and implementation tasks or workflows - Needing guidance, best practices, or checklists for sql database migration strategy and implementation ## Do not use this skill when - The task is unrelated to sql database migration strategy and implementation - You need a different domain or tool outside this scope ## Context The user needs SQL database migrations that ensure data integrity, minimize downtime, and provide safe rollback options. Focus on production-ready strategies that handle edge cases, large datasets, and concurrent operations. ## Requirements $ARGUMENTS ## Instructions - Clarify goals, constraints, and required inputs. - Apply relevant best practices and validate outcomes. - Provide actionable steps and verification. - If detailed examples are required, open `resources/implementation-playbook.md`. ## Output Format 1. **Migration Analysis Report**: Detailed breakdown of changes 2. **Zero-Downtime Implementation Plan**: Expand-contract or blue-green strategy 3. **Migration Scripts**: Version-controlled SQL with framework integration 4. **Validation Suite**: Pre and post-migration checks 5. **Rollback Procedures**: Automated and manual rollback scripts 6. **Performance Optimization**: Batch processing, parallel execution 7. **Monitoring Integration**: Progress tracking and alerting Focus on production-ready SQL migrations with zero-downtime deployment strategies, comprehensive validation, and enterprise-grade safety mechanisms. ## Resources - `resources/implementation-playbook.md` for detailed patterns and examples. --- > Source: [benjaminasterA/antigravity-awesome-skills](https://github.com/benjaminasterA/antigravity-awesome-skills) — distributed by [TomeVault](https://tomevault.io).
