We agree who owns environments, access, releases, alerts and incidents before the new platform goes live. Infrastructure and configuration belong in versioned definitions where appropriate, with a clear change and review path. Secrets stay in the agreed server or platform controls rather than source code or browser bundles. The operational plan must identify who responds when an automated check fails.
Migration and optimization changes are tested against the service requirements, including recovery and rollback. We do not promise savings before establishing a cost baseline, or certification before an independent assurance process. Handover includes the configuration, runbooks and remaining responsibilities your team needs. The result should be inspectable and maintainable, whether the next step is another workload, a new control or a routine cost review.
