Migration Recovery & Assurance

Migration recovery is a structured intervention for a cloud migration program that is stalled, repeatedly missing waves or no longer delivering the expected business outcome.
We assess the migration pipeline, dependencies, architecture, governance, defects and decision process to identify the main constraint.
The objective is not another status review. It is a practical recovery plan that can be tested through a real migration wave.

Migration delivery performs the migration work.
Migration assurance independently checks whether the program is ready to execute safely and predictably.
This can include reviewing architecture, wave plans, dependencies, test evidence, rollback, cutover readiness and governance while your existing internal teams or implementation partners continue delivery.
Capgemini, for example, describes migration assurance as working across application partners to validate and drive completion of the wider migration program rather than replacing every delivery team.

Not necessarily.
In many programs, the implementation teams already have useful knowledge and technical capacity.
Nubes can work as an independent architecture and assurance layer: clarify blockers, challenge assumptions, reset governance and help existing teams execute against clearer gates.
If a delivery workstream genuinely needs replacement or additional specialists, that decision can be made after the root cause is understood.

We start from evidence rather than existing status reports.
Typical inputs include wave plans, dependency maps, architecture decisions, defect data, failed cutovers, change records, program risks, decision backlogs, cloud readiness and interviews with application and platform owners.
We then look for the constraint that repeatedly stops workloads from progressing.
AWS recommends transparent tracking across migration workstreams because portfolio, platform, governance and migration teams operate at the same time and problems in one can block the whole pipeline.

Usually, yes.
We do not recommend pausing productive work simply because an assessment is taking place.
Healthy waves can continue. Workloads that cannot pass explicit readiness criteria may be stopped or resequenced until their blockers are resolved.
The aim is to protect useful delivery while preventing more risk from entering the pipeline.

We review the items that determine whether production can move safely.
This can include technical readiness, data synchronization, application testing, monitoring, security, stakeholder availability, communication, success criteria, rollback and operational support.
Google recommends a risk assessment for every migration wave and a rollback strategy for each migration step. AWS similarly treats the cutover as one of the highest-risk points in migration and recommends explicit governance and communication around it.

We normally create a rebaselined migration plan with clear priorities, owners, gates and decision points.
Rather than declaring the program “recovered” from a report, we recommend validating the new model through one representative migration wave.
Actual execution then shows whether the architecture, governance and operational changes work.
Microsoft recommends the same iterative principle: use milestones and actual wave results to adjust later migration plans rather than continuing with assumptions that execution has already disproved.

The exact deliverables depend on the program, but typically include a migration health fact base, constraint and dependency map, rebaselined wave plan, readiness and cutover gates, decision and responsibility model, recovery risks and an executive recovery plan.
For ongoing programs, Nubes can continue as an independent migration assurance or control function through critical migration waves.
