Before a cloud migration, map the dependencies

A cloud migration is a change to people, access, data and operations as much as it is a technology move. Begin with an inventory: workloads, owners, integrations, data, identity, licensing, backups and the periods when a service cannot be interrupted.

Choose the reason for moving

Clarify whether the goal is resilience, remote access, performance, simpler management or a new product capability. Each goal changes the architecture and the measures used to judge success. A move without a clear reason can reproduce old problems in a new environment.

Plan cutover and recovery

Document permissions, test representative data, agree a maintenance window and plan how to roll back if a critical dependency fails. Confirm backup and restore procedures before changing production traffic. Include monitoring and an owner for post-migration issues.

Make the new environment operable

After the move, review access, costs, alerts, documentation and support responsibilities. Give users a simple route to report issues. The migration is complete when the service works for the people who rely on it and the team knows how to run it.
