migrate vm network cards from DVS to standardswitch and back

[omunt]

Hi,

Does anyone know how to change a vm's nics that are connected to a DVS to a standard portgroup. (POWERCLI)

The portgroups on de standard switch have the same names as the ones on de DVS.

If possible, is it possible toe switch back from standard switch to dvs ?

We need this for a online migration of vm's between two different ESX 55 environments.

Thanks

To save the portgroup in a variable for a standard switch, you can use a command similar to the following PowerCLI command:

$PortGroup = Get-VirtualPortGroup -Name NetworkName -Virtualswitch vSwitch1 -VMHost ESXi1

To save the portgroup in a variable for a distributed switch, you can use a command similar to the following PowerCLI command:

$PortGroup = Get-VDPortgroup -Name NetworkName -VDSwitch dvSwitch0

Using the $PortGroup variable you can modify a vm's nic portgroup with a command similar to:

Get-VM -Name VM1 | Get-NetworkAdapter -Name 'Network adapter 1' | Set-NetworkAdapter -Portgroup $PortGroup -Confirm:$false

foreach($vm in $vmlist){

    Get-NetworkAdapter $vm | %{
