Looking for vCD PowerCLI script to update VM CoresPerSocket value.

Hello,

I am looking for a vCD PowerCLI script to update VM CoresPerSocket value.

I am using below but it is not working.

Connect-CIServer -Server vCD_IP -user User -password Password

$CIVM = Get-CIVM "VM_Name" -Org "ORG_Name"

$CIVM.ExtensionData.Section[0].Item[6].VirtualQuantity.Value = 2

$CIVM.ExtensionData.Section[0].UpdateServerData()

I can achieve this with vCloud REST API but i need vCD PowerCLI script.

Kindly help.
