I'm having a problem trying to figure out how to use powercli to extract virtual center version number.
any help is appreciated
You can get this information from the VIServer object returned by Connect-VIServer cmdlet.
$c = Connect-VIServer <vc_name> Write-Host $c.Version $c.Build
More detailed info you can get from ServiceInstance.Content.About SDK Object
$si = Get-View ServiceInstance $si.Content.About
