Platform Migration
Overview
This skill provides comprehensive guidance for migrating infrastructure platforms, cloud providers, container orchestration systems, CI/CD pipelines, and observability stacks. Focus is on infrastructure-level migrations that complement application modernization efforts.
Platform migrations are infrastructure-focused and should be paired with application migration strategies. Use cloud-neutral design patterns to reduce future migration effort, though multi-cloud strategies increase complexity while reducing vendor lock-in.
Core Migration Principles
Key Practices:
- Test everything in non-production first
- Automate using Infrastructure as Code (IaC)
- Migrate incrementally rather than "big bang"
- Maintain both platforms during stabilization
- Budget 20-30% more time than estimated
- Document architecture decisions and rationale
