Creating a managed disk from snapshot in different region (Azure)

Question

I seem to have a problem creating a managed disk from a snapshot.

It appears that I can only create a disk in one region which is West US.

Here is the PowerShell script I use:

Get-AzureRmSubscription –SubscriptionName 'MySubscription' | Select-AzureRmSubscription

$resourceGroupName = 'MyResourceGroup';
$diskName = 'MyNewDisk';
$location = 'West US';

$snapshotName = 'MySnapshot';
$snapshot = Get-AzureRmSnapshot -ResourceGroupName $resourceGroupName -SnapshotName $snapshotName;

$diskConfig = New-AzureRmDiskConfig -AccountType $storageType -Location $location -SourceResourceId $snapshot.Id -CreateOption Copy;
$disk = New-AzureRmDisk -Disk $diskConfig -ResourceGroupName $resourceGroupName -DiskName $diskName;

If I change the variable $region value to 'East US' or any other region, I get en error in PowerShell (resource not found).

The snapshot itself is in West US but I want to create a disk in East US. What am I doing wrong?

We can't create a managed disk from snapshot to another location.

If you want to create a managed disk from snapshot to another location, we should export/Copy managed snapshots as VHD to a storage account in different region with PowerShell.

Here the sample script:

#Provide the subscription Id of the subscription where snapshot is created
$subscriptionId = "yourSubscriptionId"

#Provide the name of your resource group where snapshot is created
$resourceGroupName ="yourResourceGroupName"

#Provide the snapshot name 
$snapshotName = "yourSnapshotName"

#Provide Shared Access Signature (SAS) expiry duration in seconds e.g. 3600.
#Know more about SAS here: https://docs.microsoft.com/en-us/azure/storage/storage-dotnet-shared-access-signature-part-1
$sasExpiryDuration = "3600"

#Provide storage account name where you want to copy the snapshot. 
$storageAccountName = "yourstorageaccountName"

#Name of the storage container where the downloaded snapshot will be stored
$storageContainerName = "yourstoragecontainername"

#Provide the key of the storage account where you want to copy snapshot. 
$storageAccountKey = 'yourStorageAccountKey'

#Provide the name of the VHD file to which snapshot will be copied.
$destinationVHDFileName = "yourvhdfilename"


# Set the context to the subscription Id where Snapshot is created
Select-AzureRmSubscription -SubscriptionId $SubscriptionId

#Generate the SAS for the snapshot 
$sas = Grant-AzureRmSnapshotAccess -ResourceGroupName $ResourceGroupName -SnapshotName $SnapshotName  -DurationInSecond $sasExpiryDuration -Access Read 

#Create the context for the storage account which will be used to copy snapshot to the storage account 
$destinationContext = New-AzureStorageContext –StorageAccountName $storageAccountName -StorageAccountKey $storageAccountKey  

#Copy the snapshot to the storage account 
Start-AzureStorageBlobCopy -AbsoluteUri $sas.AccessSAS -DestContainer $storageContainerName -DestContext $destinationContext -DestBlob $destinationVHDFileName

#Monitor status
Get-AzureStorageBlobCopyState -Context $destinationContext -Blob $destinationVHDFileName -Container $storageContainerName
