The business problem
Legacy infrastructure can become expensive, fragile, and difficult to scale. Migration creates value only when workload dependencies, business timing, security, recovery, and operational ownership are addressed together.
Common warning signs
Hardware refresh costs are increasing
Critical software is approaching end of support
Remote access is slow or difficult to secure
Recovery procedures have not been tested
New projects are delayed by infrastructure constraints
The team lacks a reliable infrastructure inventory

The seven migration strategies
Rehost
Move a workload with minimal architectural change.
Replatform
Make focused platform changes without rebuilding the application.
Refactor
Redesign application components to use cloud-native capabilities.
Repurchase
Replace a legacy system with a modern software product or SaaS service.
Retain
Keep a workload in place temporarily because migration is not yet justified.
Retire
Remove a system that no longer provides sufficient business value.
Relocate
Move virtualized infrastructure with limited changes to the guest systems.
