Cloud Migration

Cloud migration changes more than compute location. Identity, networking, data, observability, licensing, cost, and the operating model all need to move deliberately.

When this service is needed

• Applications are moving from on-premises infrastructure to cloud.
• Workloads must move between regions or cloud providers.
• Current platform cost or limitations constrain growth.
• The organisation needs a landing zone and repeatable migration pattern.

Scope

• Workload discovery and per-application migration classification.
• Landing zone, networking, IAM, security baseline, and connectivity.
• Sizing, service mapping, cost model, and target architecture.
• Data replication, migration waves, rehearsal, and cutover.
• DNS, certificates, secrets, integrations, and observability transition.
• Validation, rollback, stabilisation, and legacy-resource retirement.

Migration stages

1. Discovery: inventory assets, dependencies, owners, and criticality.
2. Design: define the target, migration method, acceptance criteria, and rollback.
3. Rehearsal: test tools, timings, data, and procedures within a controlled scope.
4. Cutover: execute the move through checklists and escalation paths.
5. Validation: prove function, integrity, security, and performance.
6. Stabilisation: monitor outcomes, remediate findings, and retire legacy systems.

Deliverables

• Inventory and dependency map.
• Migration runbook, cutover plan, and rollback plan.
• Test and reconciliation evidence.
• Target-environment documentation and decommission plan.

Intended outcomes

Workloads reach the target cloud with dependencies preserved, costs visible, security controls active, and the new operating process documented.
