To get the hassle-free migration of HDD to SSD drive done, you need to get the important prerequisites checked first. These prerequisites are mentioned below.

You should first check whether the SSD is available in the destination region.

Your Drive should be a Managed Disk.

Your Size of VM should support Premium SSD if you wish to migrate to it.

You should schedule the migration of your disk’s storage during a pre-existing maintenance window, as the conversion requires a restart of the VM.


Coming to the procedures conducted in PowerShell. You should be very careful when running the below mentioned commands to generate effectiveness, otherwise, you may end up making the whole procedure a liability.


You need to run Connect-AzureRmAccount in PowerShell with Azure RM module included in it to create a connection with Azure.

The following example shows how to switch a single disk of a VM from standard HDD to standard SSD, and vice versa.

$diskName = 'yourDiskName'

$rgName = 'yourResourceGroupName'

$storageType = 'StandardSSD_LRS'

$disk = Get-AzureRmDisk -DiskName $diskName -ResourceGroupName $rgName

$vmResource = Get-AzureRmResource -ResourceId $disk.ManagedBy

Stop-AzureRmVM -ResourceGroupName $vmResource.ResourceGroupName -Name $vmResource.Name -Force

$vm = Get-AzureRmVM $vmResource.ResourceGroupName -Name $vmResource.ResourceName

$diskUpdateConfig = New-AzureRmDiskUpdateConfig -AccountType $storageType -DiskSizeGB $disk.DiskSizeGB

Update-AzureRmDisk -DiskUpdate $diskUpdateConfig -ResourceGroupName $rgName ` -DiskName $disk.Name

Start-AzureRmVM -ResourceGroupName $vm.ResourceGroupName -Name $vm.Name
