- AVD + VDI
- Planning for Azure Virtual Desktop, older VDI and eligible Azure VMs
- One batch at a time
- Personal AVD desktops and eligible Azure VMs move to Windows 365 Enterprise on a schedule, each batch tracked
- Tracked
- Schedule, import, history, statistics and cleanup in one place
Size it in three minutes.
Compare Azure Virtual Desktop and Cloud PC cost per user before you commit to a migration. Free, no email needed.
Migrations stall in the manual steps.
Mixed sources, user mapping and cleanup are where migrations slip.
What is happening
Source estates are mixed.
Some desktops are AVD, some are Azure VMs, some are older VDI, each with its own preparation.
Why it gets missed
Progress is hard to defend.
Teams need to show what moved, what failed and how long it took, batch by batch.
What good looks like
Tracked batches, cleaned up after.
Readiness, user mapping and scheduling around the Windows 365 migration API, with history for every batch.
Moving to Cloud PCs one batch at a time.
Which personal desktops are eligible to move, then one machine and scheduled batches, each one reviewed by a person and recorded.

The current walkthrough shows the wider Cloud PC operating view. The migration page is designed to take screenshots from the dedicated migration workflow when those assets are ready.
A guided route from source VM to managed Cloud PC.
Each batch keeps its AVD or VDI baseline on the record, so you can prove the move paid off, batch by batch.
Select and validate the source
Start from AVD personal desktops or eligible Azure VMs.
Map the user and prepare the import
Match source desktops to users and check readiness.
Schedule the migration window
Plan around maintenance windows and licence assignment.
Track, review and clean up
Import status, history, duration statistics and post-migration cleanup.
Windows 365 vs Azure Virtual Desktop, side by side
Both run on Microsoft's Cloud PC and virtual desktop stack, but the operating model is different. Use this table for a first-pass read before an assessment; EtherInsights maps your current AVD or VDI baseline against the Windows 365 model in detail.
| Decision factor | Windows 365 | Azure Virtual Desktop |
|---|---|---|
| Persistence | A dedicated, 1:1 Cloud PC per user | Pooled or shared session hosts, with 1:1 personal desktops also possible |
| Admin surface | Microsoft Intune and the Microsoft 365 admin center | Azure portal for host pools and session hosts, plus Intune for device management |
| FSLogix profiles | Not required for most personal Cloud PC assignments | Commonly required to manage user profiles across pooled or shared desktops |
| Pricing model | Fixed per-user Cloud PC licence, sized by vCPU, RAM, and storage | Consumption-based Azure compute and storage, scales with session-host usage |
| UK data residency | Provisioning policy sets the Azure region a Cloud PC is created in | Host pool region choice gives the same Azure region control |
