Objective

Migrate an application estate to the cloud safely and on budget. Each wave is planned by dependency, rehearsed, cut over with rollback ready, and optimised after it lands so run costs match the business case.

You may need this if

  • A data centre exit date is fixed
  • The assessment is done and the business case is approved
  • Previous migrations overran or were rolled back
How it runs

Activities, step by step

The plan follows our delivery framework. Steps that do not apply to this kind of work are left out rather than padded.

  2. 03 · Alpha3–4 weeks

    Pilot wave

    • Low-risk applications migrated first
    • Runbook refined from real cutovers
    • Performance and cost compared with forecast
  3. 04 · Beta6–16 weeks

    Migration waves

    • Rehost, replatform or refactor by workload
    • Rehearsed cutovers with business sign-off
    • Hypercare after each wave

    • Rightsizing and reserved capacity
    • Source infrastructure decommissioned
    • Operations handed over
