Migration Strategies

Lift and Shift (Rehosting)

Best for: Quick migration with minimal changes Timeline: 2-6 months Cost: Lowest migration cost Risk: Low technical risk Example: Moving existing servers to cloud VMs

Replatforming

Best for: Moderate optimization needs Timeline: 3-9 months Cost: Medium migration cost Risk: Medium technical risk Example: Moving to managed database services

Refactoring

Best for: Maximum cloud benefits Timeline: 6-18 months Cost: Highest migration cost Risk: Higher technical risk Example: Rebuilding as cloud-native applications
