Cloud Migration Services

Migration of on-premises infrastructure and applications to the cloud, sequenced so each stage can be validated before the next begins.

The problem

What usually brings people to this.

  • Migrations attempted as a single cutover with no rollback
  • Applications moved without their dependencies mapped
  • Downtime windows that the business cannot absorb
What we do

Move on-premises infrastructure and applications in validated stages

We move on-premises infrastructure and applications to the cloud in stages, each with defined success criteria and a rollback position. Dependencies are mapped before anything moves, and the target environment is built and validated before the first workload lands in it.

  • 01

    Dependency mapping

    Application and infrastructure dependencies established before sequencing.

  • 02

    Landing zone build

    The target environment built and validated ahead of migration.

  • 03

    Staged migration execution

    Workloads moved in waves with defined validation gates.

  • 04

    Cutover and rollback planning

    Each stage carries a tested rollback position.

Technologies and frameworks in scope

  • Microsoft Azure
  • AWS
Methodology

How the engagement runs.

A defined sequence, so you know what is happening at any point and what comes out of each stage.

  1. 01

    Dependency mapping

    Application and infrastructure dependencies established before anything is sequenced.

    • Application dependencies
    • Infrastructure dependencies
  2. 02

    Landing zone build

    The target environment built and validated ahead of migration.

    • Target environment
    • Security baseline
    • Validation
  3. 03

    Migration sequencing

    Workloads grouped into waves, each with defined success criteria.

    • Waves
    • Success criteria
    • Change windows
  4. 04

    Staged migration execution

    Each wave moved and validated before the next one begins.

    • Wave execution
    • Validation gates
  5. 05

    Cutover and rollback

    Every stage carries a rollback position that has been tested, not documented.

    • Cutover plan
    • Tested rollback
  6. 06

    Validation and handover

    Confirm behaviour in the target environment and leave the documentation behind.

    • Functional validation
    • Performance validation
    • As-built documentation
Deliverables

What you receive.

  • 01Application and infrastructure dependency map
  • 02Landing zone design and as-built documentation
  • 03Migration plan with wave sequencing
  • 04Cutover and rollback plan per wave
  • 05Post-migration validation report
Outcome

What changes afterwards.

  • Workloads moved in stages rather than in a single cutover
  • A tested rollback position at every stage
  • Dependencies understood before they cause an outage
  • A target environment proven before the first workload lands in it

Questions

Before you get in touch.

Do you map dependencies before anything moves?

Yes — application and infrastructure dependencies are established before sequencing, so migration order reflects what actually depends on what, not just what's easiest to move first.

Is the target environment built before or after migration starts?

Before — the landing zone is built and validated ahead of migration, so the first workload lands in an environment that has already been proven, not one built alongside it.

What happens if a migration wave doesn't go to plan?

Every stage carries a tested rollback position as part of cutover and rollback planning, agreed before that stage begins.

How does this relate to Cloud Strategy & Modelling?

Cloud Strategy & Modelling decides what moves, in what order and on what commercial basis; Cloud Migration Services then executes that plan in validated stages.
