Move VMs into another Cloud on SCVMM 2012 R2 via PowerShell
Posted in Virtual Machine Manager, Windows Powershell | No Comment | 3,314 views | 15/02/2014 12:41

You can use this script to move your VMs into another Cloud (Cloud Migration) on SCVMM 2012 R2.
This script only works on SCVMM 2012 R2 due to vHBA control.
You can remove vHBA control to make it work on SCVMM 2012 SP1.
