The 7 R Rangers — effort vs. reward
Before a single server moves, Maya walks the halls of Fort Rusty and assigns every application to one of seven Rangers — the industry's 7 R migration strategies. There's no single "best" R; the right call depends on each app's value, risk, and how much change it can bear. Read the map from bottom-left (cheap & easy, little change) toward top-right (harder & costlier, but the biggest cloud payoff), and tap a Ranger to learn when to call them. Gizmo will whisper "just rehost everything!" — but a good portfolio usually mixes several Rs.
- RetireSwitch it off — no cloud target
- RetainKeep on-prem, revisit later
- RehostLift & shift, no code changes
- RelocateMove a whole hypervisor estate
- RepurchaseDrop & shop — swap for SaaS
- ReplatformLift, tinker with managed services
- RefactorRe-architect fully cloud-native
