Copy standard switch port groups from one esx host to another

The below code asks for lmvap-vcs60 credentials, connects to Vcenter, and copied aesx11 vSwitch2 portgroups over to a new host called aesx05 using vSwitch1. (or so said my buddy Josh O. who wrote it) 

$vccred = get-credential

connect-viserver -server lmvap-vcs60.domain.tld -credential $vccred

$dest = get-virtualswitch -name vSwitch1 -vmhost aesx05.domain.tld

$source = get-virtualportgroup -vmhost aesx11.domain.tld -virtualswitch vSwitch2 -standard

$countvar = $source.count

for ($a=0 ; $a -le $countvar-1 ; $a++)

{

$pgname = $source[$a].name

$vlan = $source[$a].VLANID

new-virtualportgroup -virtualswitch $dest -name $pgname -VLANID $vlan

}

disconnect-viserver -server lmvap-vcs60.domain.tld -confirm:$false
