Why phased migrations win
Cloud migration promises lower overhead, anywhere-access, and built-in resilience — but rushed migrations cause outages and data loss. The answer is a phased, assessment-first playbook.
The five phases
| Phase | What happens |
|---|---|
| Assess | Inventory mailboxes, files, apps, and dependencies; check readiness. |
| Plan | Design target architecture, licensing, and a migration sequence. |
| Pilot | Migrate a small test group and validate everything works. |
| Migrate | Move in waves with controlled cutovers — never "big bang". |
| Optimize | Apply security baselines, right-size licensing, decommission old kit. |
Common workloads
- Exchange → Exchange Online — email, calendars, contacts.
- File servers → SharePoint / OneDrive — with permissions mapped.
- On-prem servers → Azure — lift-and-shift or re-platform.
- Identity → Entra ID — the anchor for everything else.
Assessment first, always. IDENETY starts with a Cloud Migration Assessment (from $2,500) to surface risks — legacy apps, mailbox sizes, bandwidth — before committing to a cutover date. It's the cheapest insurance in IT.
Avoiding the classic pitfalls
Underestimated data volumes, forgotten shared mailboxes, broken file permissions, and missed DNS records derail migrations. A structured playbook — and a tested pilot — eliminates the surprises.
