Rename a Standard Port Group on all hosts in a cluster

Well, I recently decided to rename a bunch of my Standard Port Groups, since they did no longer reflect the network they were providing. Since I’m a lazy bastard (well lazy as in click lazy), I wrote this little PowerCLI script:

This script basically takes a vCenter instance and a single cluster, then creates a new Port Group on each host, after which it reconfigures all VMs possessing a virtual NIC with that Port Group and then deletes the old Port Group.
