Snapshot Migration to different location

Powershell script

snapshot-mg-eastus-to-india.ps1

To execute the powershell script use below command.

./snapshot-mg-eastus-to-india.ps1

$SnapshotResourceGroup = "source-resource-group-name"
$SnapshotName = "source-snapshot-name"
$StorageAccount = "dest-storage-name"
$StorageAccountcontainer = "dest-container-name"
$storageaccountResourceGroup = "dest-resource-group-name"
$snapshotshotinblobname = "dest-snapshot-name" #(it would be same as source snapshot name or different as per your preference)


Start-Sleep -Seconds 5
$snapshot = Get-AzSnapshot -ResourceGroupName $SnapshotResourceGroup -SnapshotName $SnapshotName
$StorageAccountKey = (Get-AzStorageAccountKey -Name $StorageAccount -ResourceGroupName $StorageAccountResourceGroup).value[0]
Write-Output "Granting $($SnapshotName) access"
$snapshotaccess = Grant-AzSnapshotAccess -ResourceGroupName $SnapshotResourceGroup -SnapshotName $SnapshotName -DurationInSecond 3600 -Access Read -ErrorAction stop 
$DestStorageContext = New-AzStorageContext –StorageAccountName $storageaccount -StorageAccountKey $StorageAccountKey -ErrorAction stop
Write-Output "Begin snapshot: ($SnapshotName) copy to $snapshotshotinblobname.vhd"
$copy = Start-AzStorageBlobCopy -AbsoluteUri $snapshotaccess.AccessSAS -DestContainer $StorageAccountcontainer -DestContext $DestStorageContext -DestBlob "$($snapshotshotinblobname).vhd" -Force -ErrorAction stop
Write-Output "Completed snapshot: ($SnapshotName) copy to $snapshotshotinblobname.vhd"
Start-Sleep -Seconds 20
$copy | Get-AzStorageBlobCopyState
Start-Sleep -Seconds 240
$copy | Get-AzStorageBlobCopyState
Start-Sleep -Seconds 240

To see the migration progress use below command.
