A practical order of operations for moving workloads to Microsoft 365 and Azure: inventory, identity, networking, data residency, and rollback — without the weekend surprise.
Cloud migration is not a single weekend cutover. It is a sequence of decisions about identity, data residency, dependencies, and rollback. This checklist reflects what Amen Security uses with Canadian clients moving to Microsoft 365 and Azure in 2026.
Most failed migrations trace back to identity — not storage. Before moving mailboxes:
Canadian clients often require clarity on where data lives. Confirm Microsoft 365 tenant region, Azure resource groups, and backup copy locations. Document subprocessors for privacy questionnaires.
Define rollback triggers: authentication failure rate, critical app incompatibility, data loss beyond RPO. Run a tabletop with executives and IT — who decides to roll back, and within what window?
