## ESXi source and destination

$esx_d = Get-VMHost esx02*
## vSwitch name source and destination
$vswitch_s = "vSwitch1"
$vswitch_d = "vSwitch1"
$portgroup = $esx_s | Get-VirtualSwitch -Name $vswitch_s | Get-VirtualPortGroup | Select-Object Name, vlanid
$vswitch = $esx_d | Get-VirtualSwitch -Name $vswitch_d
### Add Port Group
FOREACH ($pg in $portgroup) {
