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
