  1. Does this makes any difference?

    $vCenterIP =”vc.vmzoneblog.com”
    Connect-VIServer $vCenterIP
    $myDatacenter =”nukescloud”
    $Cluster =”sgp”
    $NewDVS =”DSwitch”
    $NicName =”vmnic4″
    $UplinkName=”Uplink 4″
    $hostnames=Get-Datacenter -Name $myDatacenter | Get-Cluster -Name $Cluster | Get-VMHost
    $hostnames=$hostnames.name
    ForEach ($hostname in $hostnames)
    {
    Write-Host -ForegroundColor red “The $hostname already has 1 or more physical Nics on $NewDVS”
    $EsxHost = Get-VMHost -Name $hostname
    $vds = Get-VDSwitch -Name $NewDVS -VMHost $EsxHost
    $uplinks = Get-VDPort -VDSwitch $vds -Uplink | where {$_.ProxyHost -like $hostname}
    $netSys = Get-View -Id $EsxHost.ExtensionData.ConfigManager.NetworkSystem
    $config = New-Object VMware.Vim.HostNetworkConfig

    $config.ProxySwitch[0] = New-Object VMware.Vim.HostProxySwitchConfig
    $config.ProxySwitch[0].Uuid = $vds.ExtensionData.Uuid
    $config.ProxySwitch[0].ChangeOperation = [VMware.Vim.HostConfigChangeOperation]::edit
    $config.ProxySwitch[0].Spec = New-Object VMware.Vim.HostProxySwitchSpec
    $config.ProxySwitch[0].Spec.Backing = New-Object VMware.Vim.DistributedVirtualSwitchHostMemberPnicBacking

    $netSys.UpdateNetworkConfig($config, $changeMode)
    Write-Host -ForegroundColor Green “Moved $NicName for $hostname to $NewDVS $UplinkName”
    }
    Disconnect-viserver -confirm:$false

  2. Found a Fix. The lines 28,29 had incorrect syntax correct code below
    $config.ProxySwitch[0].Spec.Backing.PnicSpec[1].PnicDevice = ($uplinks| Where-Object {$_.ConnectedEntity.Name -like “vmnic*”}).ConnectedEntity
    $config.ProxySwitch[0].Spec.Backing.PnicSpec[1].UplinkPortKey = ($uplinks| Where-Object {$_.ConnectedEntity.Name -like “vmnic*”}).Key
