Script to upgrade either a list of VMs to Virtual HW 7 OR all VMs on either ESX(i) or vCenter system. Prior to upgrading, the script will validate that the VM is poweredOff and the version of Virtual HW is not already configured on the VM. Also ensure that your VMs have the latest version of VMware Tools installed as there are changes to the vNIC when going from HW4 to HW7 which you'll get a question prompted if you don't have tools installed.
ESX(i) 4.0 or vCenter 4.0
vSphere SDK for Perl or vMA 4.0
VM(s) running Virtual HW Ver 4 and VMware Tools installed & are poweredOff prior to upgrade
