Migration Engineering

Phased migration with rollback at every stage.

I map dependencies before anything moves, run parallel environments until cutover is validated, and hand back rollback runbooks your team can execute without me.

Scope a project.

Where Migrations Break

Most migration failures are sequencing failures. The workload moves before the dependencies are understood.

The pattern repeats across environments.

Invisible dependencies: Services bound to hardcoded IPs, local DNS, or file paths that only surface after cutover.
Big-bang cutovers: Everything moves on one weekend. When something breaks, there is no clean path back.
Missing rollback: The plan assumed success. Recovery means rebuilding from backups under pressure.

I move workloads in phased waves. Each wave has an explicit rollback boundary. Nothing cuts over until the parallel environment validates cleanly.

Deliverables

Dependency Map

Pre-migration audit of every workload covering network bindings, service accounts, storage paths, and integration points. Undocumented dependencies are flagged before they become production incidents.

Parallel-Run Architecture

Source and target environments operate side by side during each wave. Functional parity is verified under load before any cutover decision is made.

Rollback Runbooks

Step-by-step reversal procedures for every migration wave. Each runbook is tested before the forward cutover proceeds.

Cutover Validation and Handoff

Post-migration verification against defined success criteria. Documentation and operational procedures transfer to your team at close.

What affects scope.

Complexity Factors

Undocumented Legacy Systems↑ Increases

Multi-Vendor Coordination↑ Increases

Compliance / Regulatory Needs↑ Increases

Standard "Lift & Shift" Scope↓ Decreases

Field Evidence
