Add AD group as Administrator on esxi

Hello All

I have esxi connected to AD group already

Now i need to add one ad group to Esxi Administrator

New-VIPermission

I saw a note from LucD

$oldGroup = 'domain\oldgroup'

$newGroup = 'domain\newgroup'

foreach($esx in Get-VMHost){

    $oldPerm = Get-VIPermission -Entity $esx | where {$_.Principal -eq $oldGroup -and !$_.Propagate}

    New-VIPermission -Entity $esx -Principal $newGroup -Role $oldPerm.Role -Propagate $oldPerm.Propagate -Confirm:$false

    Remove-VIPermission -Permission $oldPerm -Confirm:$false

}

But i am not able to co-relate it to my case

my esxi are running 6.0x
