Using PowerShell to Live Migrate to a Computer with a Different Virtual Switch

  • Article

So far this week I have shown you how to register and how to import virtual machines with configuration problems using PowerShell.  However, the question I most often hear is this one: how do I use PowerShell to live migrate a virtual machine to another computer – where the virtual switch names do not match?

Once again – the answer is: “Use Compare-VM”

Here you can see that I try and use Move-VM to live migrate a virtual machine, and I get an error because the virtual switch names do not match.  And just like in the other cases, I call Compare-VM and give it the same parameters as when I tried to use Move-VM.

compare-move

After doing this I just need to fix the incompatibilities and pass the results into Move-VM.

Cheers,
Ben

    Is there any command, we can set the parameter to use destination virtual switch during the live migration. for eg: VM running on the host with VSW1 and destination host virtual swtich VSW2. As we are telling the DestinationHost, can we set Destination VirtualSwtich...?

    I'm trying to use Compare-VM when migrating a VM to a host with a different virtual switch as you describe, but not having much luck. When I run the command below on the Hyper-V source server, I get an error 'Connect-VMNetworkAdapter: Hyper-V was unable to find a virtual switch with the name "Hyper-V Network"'. $VMReport.Incompatibilities | ?{$.messageid -eq 33012}| %{connect-vmnetworkadapter $.Source -switchname "Hyper-V Network"}I know this is an old post, but if the author or anyone else has run into this or has a suggestion as to where I'm going wrong, I'd appreciate it. Thanks!
