Re: Migrating vmnics to Cisco 1000v with portgroup (nearly there!)

I managed to solve this using:

$config = New-Object VMware.Vim.HostNetworkConfig 
$config.proxySwitch = New-Object VMware.Vim.HostProxySwitchConfig[] (1) 
$config.proxySwitch[0] = New-Object VMware.Vim.HostProxySwitchConfig 
$config.proxySwitch[0].changeOperation = "edit" 
$config.proxySwitch[0].uuid = $1000vObject.key 
$config.proxySwitch[0].spec = New-Object VMware.Vim.HostProxySwitchSpec 
$config.proxySwitch[0].spec.backing = New-Object VMware.Vim.DistributedVirtualSwitchHostMemberPnicBacking 
$config.proxySwitch[0].spec.backing.pnicSpec = New-Object VMware.Vim.DistributedVirtualSwitchHostMemberPnicSpec[] (1) 
$config.proxySwitch[0].spec.backing.pnicSpec[0] = New-Object VMware.Vim.DistributedVirtualSwitchHostMemberPnicSpec 
$config.proxySwitch[0].spec.backing.pnicSpec[0].pnicDevice = "vmnic0" 
$config.proxySwitch[0].spec.backing.pnicSpec[0].uplinkPortgroupKey = $uplinkObj.key  

$vmhostRef = ($vmhost.MoRef.value).split('-')[1]
$_this = Get-View -Id "HostNetworkSystem-networkSystem-$vmhostRef" 
$_this.UpdateNetworkConfig($config, "modify")
