Platform Migration

Migration is a portfolio decision before it is a technical one. Some workloads should be rehosted and left alone, some rebuilt, and some retired entirely. Deciding that per workload - with the cost modelled before the move - is what separates a migration that pays back from one that just relocates the problem.

When this helps

You are probably reading this because of one of these.

  • A data centre contract or hardware refresh is forcing a decision
  • A previous lift-and-shift raised costs without improving anything
  • Security and compliance requirements have outgrown the current platform
  • Scaling means buying hardware months ahead of demand

How we help

A delivery sequence, not a discovery phase that never ends.

Every stage produces something you can act on independently, so the engagement can stop at any point without leaving you stranded mid-programme.

  1. Inventory

    Catalogue every workload with its dependencies, data gravity, compliance constraints, and true running cost.

  2. Decide

    Choose rehost, replatform, rebuild, or retire per workload, with the cost and risk modelled for each.

  3. Land

    Build the landing zone first: networking, identity, security guardrails, and cost controls before any workload moves.

  4. Migrate

    Move in waves, lowest risk first, with parallel running and a tested rollback for every wave.

Efficiencies driven

The measurable change this engagement is aiming at.

Where teams usually start

  • Capacity bought months ahead of demand
  • Security controls applied inconsistently per system
  • Cloud costs discovered on the invoice

Where the engagement leaves you

  • Capacity matched to demand and paid for as used
  • Guardrails enforced centrally in the landing zone
  • Costs modelled before the move and monitored after

What you receive

Artefacts that outlive the engagement.

  • Workload inventory with dependencies and current running cost
  • Per-workload migration decision with modelled target cost
  • AWS or Azure landing zone with identity, network, and guardrails
  • Wave plan, cutover runbooks, and tested rollback procedures
  • Post-migration cost and performance baseline

Next step

A short call is usually enough to work out whether this is the right engagement, and what it would cost. If it is not, I will say so.
