I created the VDS and dvPG with the following ($cboLoc is just a drop down list):
New-VDSwitch -Name "$($cboLoc.Text)-Management" -Location $myDC -MaxPorts 136
Get-VDSwitch -Name "$($cboLoc.Text)-Management" | New-VDPortgroup -Name "Management Network" -NumPorts 128
At this point, I am trying to migrate the existing management VSS to the new VDS as we are getting ready to migrate to VDS.
