Move Azure Snapshot to new Subscription — PowerShell

At the time of writing this, moving/migration of VMs with managed disks to a new Azure Subscription, is not supported in Azure. It is possible however, to move managed snapshots of a VM’s vhds to another Azure subscription, and then ‘reconstruct’ the VM using the OS and data disks snapshots or managed disks. The VM object itself is just metadata running the vhds (The Move option for both snapshots or managed disks displays in the Azure portal, but we found that the portal Move option does not work for our various Azure Accounts and Subscriptions.(See screen shot below).) The Move operations of snapshots or managed disks can be done easily via PowerShell.
