For an Azure VM, you can stop protection with retained data for the VM in the LRS vault, move the VM to another resource group, and then help protect the VM in the GRS vault. For information about moving a VM to another resource group, see the guidance and limitations.

Hope this helps. Feel free to ping me if you have any questions!
