Microsoft Azure --- how to move VM from one cloud service to another

In the same Azure Subscription, each VM will build into a new cloud service if we create a new VM by taking the default set of options in the wizard. So do that we will reach the limit of 20 cloud service and the next new VM cannot be created besides apply for the request to Microsoft Cloud Help Desk.

“Whether VMs can move between different cloud services?” The following process will finish this thought.
Get the VM information by using the Get-AzureVM -servicename “<old cloud service name>” -name “<VM name>” command

Export this VM config by using the Export-AzureVM -ServiceName “<old cloud service name>” -name “<VM name>” -path “<.xml file>” command

Remove this VM from Azure but doesn’t delete the VHD file on disk (# 1) by using the Remove-AzureVM -ServiceName “<old cloud service name>” -Name “<VM name>” command

Edit the .xml file if we want to change local port number or Subnet Name for being compatible with the destination cloud service.

Ensure the current storage account is accessible by executing the Get-AzureSubscription command. If we find out the CurrentStorageAccount is blank, please choose what storage account this VMis in by using the set-AzureSubscription -SubscriptionName “<Azure Subscription>” -CurrentStorageAccount “<new Storage Account>” command. (# 2)

Import the VM config for creating this VM back to Azure by using the Import-AzureVM -path “<.xml file>” | New-AzureVM -ServiceName “<new cloud service name>” -VNetName “<virtual network name>” command.

So does that the VM has already been moved to another cloud service.

Reference :
(# 1)   Click on the Storage Icon on the left、select a storage account to open the Storage Main Page、click on the Containers tab and vhds item. We can see the removed VHD file in the list.

(# 2)   If the CurrentStorageAccountName is not defined, we will get the following error message when execute the Import-AzureVM powershell command.
