Drift check
Rediscover source and target state, recreate provider previews, and invalidate approval when material differences appear.
Controlled cloud migration execution binds changes to an approved manifest, uses scoped identities, holds at checkpoints, and validates every stage before progression. Currently delivered through qualified engagements while release-acceptance evidence completes.
A durable state machine controls task order, locks, idempotency, timeouts, approvals, checkpoints, budgets, and compensation. Intelligence services return typed diagnoses and proposals for deterministic validation.
Rediscover source and target state, recreate provider previews, and invalidate approval when material differences appear.
Run only manifest actions through typed AWS, Azure, or GCP provider capabilities and scoped customer identities.
Classify failures, validate the least-invasive approved repair, retry idempotently, or roll back the current stage.
Run acceptance, reconciliation, policy, security, performance, observability, and cost checks before progression.
Each stage has entry criteria, exit criteria, budget limits, checkpoints, recovery rules, and rollback or failback conditions.
| Stage | Primary control | Evidence before progression |
|---|---|---|
| Foundation | Identity, network, policy and observability readiness | Provider state and policy results |
| Target infrastructure | Approved manifest actions only | Configuration and dependency validation |
| Data and application | Checkpointed transfer and deployment | Integrity, startup and connectivity tests |
| Cutover | Named approver and maintenance window | Final sync, health and rollback readiness |
| Validation | Migration Contract acceptance criteria | Reconciliation and client acceptance evidence |
Recovery remains inside the approved target design, provider capabilities, policy controls, and Recovery Envelope.
Transient backoff, checkpoint resume, and dependency-order correction.
Preview policy-valid normalization or an approved alternative already present in the manifest.
Execute defined compensation and confirm source authority remains available.
Present evidence, impact, recommended choice, alternatives, and schedule consequence.
Walk through manifest binding, identity scope, recovery limits, cutover gates, and completion evidence.
