After an initial deployment, you might run into the need of changing the initial disk performance SKU in Azure. In the example below, we’re updating the SKU from Standard_LRS to Premium_LRS. In your PowerShell session type:

New-AzDiskUpdateConfig -Sku Premium_LRS | Update-AzDisk -ResourceGroupName yourresourcegroup -Name yourdiskname

It comes helpful to know how to update the size of a newly created disk in Azure. So, in your PowerShell session type:

New-AzDiskUpdateConfig -DiskSizeGB 64 | Update-AzDisk -ResourceGroupName yourresourcegroup -DiskName thenameofyourdisk

Verify:

Get-AzDisk -ResourceGroupName yourresourcegroup -Name thenameofyourdisk

Sometimes it helps to create a resource group in Azure that has the same location as a specific desired resource group. Open an Azure PowerShell session and type:

$location = (Get-AzResourceGroup -Name theresourcegroupiwanttocopyfrom).Location
$rgname = 'thenewresourcegroup'
New-AzResourceGroup -Name $rgname -Location $location

In order for PowerShell scripts to be run, a less restrictive policy must be set. Like “Remote signed”, for example. In order to change the current PowerShell execution script policy to remote signed for the current user, type:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

In order to determine the current PowerShell script execution policy type:

Get-ExecutionPolicy -List
