Cloud Migration Readiness: A Business Checklist

The quick answer

Inventory workloads and dependencies, set recovery and performance requirements, estimate ongoing costs and test a migration with acceptance and rollback criteria before moving critical services.

Map the workload and its dependencies

Identify the application owner, users, data stores, integrations and scheduled tasks. Record dependencies on identity, email, network paths and third-party systems. Include external users and branch locations in the access review.

Decide whether the workload should move as it is, be redesigned, be replaced or remain where it is for now. Base the decision on business needs and technical constraints rather than assuming that every workload benefits from the same migration approach.

Agree availability and recovery requirements

Ask the business how much interruption and data loss it can tolerate. Translate the answer into recovery objectives and operating responsibilities. Check that the proposed architecture and support arrangement can be tested against those objectives.

Back up the source and rehearse restoration. Define a rollback decision point before the migration starts, including who makes the decision and what must happen to data changed during the migration window.

Estimate the operating cost and controls

Model ordinary use, busy periods, storage growth, backups, network transfer and support. Record the assumptions so the estimate can be revisited. An initial infrastructure price rarely describes the whole monthly operating cost.

Prepare identity, least-privilege access, logging, monitoring and budget alerts before launch. Agree which team receives each alert and what action is expected. An alert without an owner is not an operating control.

Migrate in waves and verify business journeys

Start with a lower-risk workload that can teach the team about the process. Use those findings to adjust later migration waves. Communicate the change window and expected impact to affected users.

After cutover, test complete user journeys as well as infrastructure health. Check integrations, scheduled jobs, permissions, reports and backup recovery. Keep the original environment until agreed acceptance and retention criteria allow it to be retired.

Common questions

Will moving to the cloud always reduce costs?

No. Cost depends on architecture, consumption, licensing, migration effort and operations. Compare a documented cost model with the current environment.

Can migration be completed without downtime?

The feasible interruption depends on the workload, data transfer approach and architecture. Plan and test the change window rather than promising zero downtime for every system.
