Migration Waves
"Move applications without scaring users or breaking margins"
Sequenced cloud migration waves with parallel-running, tested rollback at every step, and minimised production impact. Six R's applied per workload — rehost, replatform, refactor, rebuild, replace, retire.
Six migration surfaces
Application portfolio analysis
Per-workload disposition decisions across the six R's.
Wave sequencing
Risk-weighted batches with dependency mapping and rollback strategy.
Lift & shift
Compute, storage, and network rehosting with minimal code changes.
Replatforming
Adopt managed services (databases, queues, autoscaling) selectively.
Data migration
CDC, dual-write, replay, reconciliation — no data loss.
Cutover & decommission
Rehearsed cutover with traffic shifting, monitoring, and rollback playbook.
Four-step per-wave cadence
Plan
Workloads scoped, dependencies mapped, cutover plan rehearsed.
Mirror
Target environment provisioned and validated with shadow traffic.
Cutover
Traffic shifted progressively with rollback ready at every step.
Stabilise
Production monitored under steady-state, decommission scheduled.
