If the region where your availability set is located has only 2 managed fault domains but the number of unmanaged fault domains is 3, this command shows an error similar to "The specified fault domain count 3 must fall in the range 1 to 2." To resolve the error, update the fault domain to 2 and update Sku to Aligned as follows: $avSet.PlatformFaultDomainCount = 2ĭeallocate and migrate the VMs in the availability set. Update-AzAvailabilitySet -AvailabilitySet $avSet -Sku Aligned $avSet = Get-AzAvailabilitySet -ResourceGroupName $rgName -Name $avSetName The following example updates the availability set named myAvailabilitySet in the resource group named myResourceGroup: $rgName = 'myResourceGroup' Migrate the availability set by using the Update-AzAvailabilitySet cmdlet. If the VMs that you want to migrate to managed disks are in an availability set, you first need to migrate the availability set to a managed availability set. The following process converts the previous VM, including the OS disk and any data disks, and starts the Virtual Machine: ConvertTo-AzVMManagedDisk -ResourceGroupName $rgName -VMName $vmName Migrate the VM to managed disks by using the ConvertTo-AzVMManagedDisk cmdlet. Stop-AzVM -ResourceGroupName $rgName -Name $vmName -Force The following example deallocates the VM named myVM in the resource group named myResourceGroup: $rgName = "myResourceGroup" (If your VMs are in an availability set, see the next section.)ĭeallocate the VM by using the Stop-AzVM cmdlet. This section covers how to migrate single-instance Azure VMs from unmanaged disks to managed disks. If you need to find these unattached disks in order to delete them, see our article Find and delete unattached Azure managed and unmanaged disks. To avoid being billed for these artifacts, delete the original VHD blobs after you verify that the migration is complete. The original VHDs and the storage account used by the VM before migration are not deleted.For information on how to check and update your agent version, see Minimum version support for VM agents in Azure Review the minimum version of the Azure VM agent required to support the migration process. If needed, you can assign a static IP address to the VM. The VM receives a new IP address when it's started after the migration. Migrate a test virtual machine before you perform the migration in production.ĭuring the migration, you deallocate the VM. This is because VMs with managed disks require the user to have the Microsoft.Compute/disks/write permission on the OS disks.īe sure to test the migration. The migration will restart the VM, so schedule the migration of your VMs during a pre-existing maintenance window.Īny users with the Virtual Machine Contributor role won't be able to change the VM size (as they could pre-migration). Review the FAQ about migration to Managed Disks.Įnsure the VM is in a healthy sate before converting. Review Plan for the migration to Managed Disks. This process converts both the operating system (OS) disk and any attached data disks. Hosts has Windows 2019 Standard installed.If you have existing Windows virtual machines (VMs) that use unmanaged disks, you can migrate the VMs to use managed disks through the Azure Managed Disks service.
