Cloud Migration Risk Checklist Before Cutover

Use this checklist to reduce downtime, cost spikes, and security regressions during cloud migration.

Updated: 4/3/2026

Direct Answer

Validate rollback plans, dependency maps, access controls, and production observability before cutover. Missing any one of these is the main cause of high-impact migration incidents.

Pre-cutover technical checks

Dependency inventory is complete across services, queues, and cron jobs.
Rollback path is tested on a staging environment with production-like data shape.
Monitoring, alerts, and runbooks are active before traffic shift.

Security and compliance checks

Least-privilege IAM is applied to workloads and operators.
Encryption settings are validated for data at rest and in transit.
Audit logging and access review cadence are documented.

Business continuity checks

Stakeholders know the migration window and fallback trigger.
Customer support has a communication playbook for incidents.
Post-cutover review is scheduled with owners and deadlines.

FAQs

Should we migrate everything at once?

No. Phased migration with controlled traffic ramps significantly reduces risk and allows faster recovery.

What is the first rollback signal?

Define SLO-based triggers in advance, such as sustained error-rate increase or latency breach beyond threshold.
