  • 1.  Help Migrating VMs

    Posted Sep 12, 2017 07:18 PM

    A little history.  I'm trying to migrate some VMs from a cluster running vSphere 5.1 to a new vSphere 6.0 vSAN Cluster.  Via the web client, if I do a migrate both Compute & Storage option, and choose STORAGE FIRST, I can go through the wizard, choose the destination vSAN Datastore, then the host in that cluster, then the destination Network Portgroup, and I get a warning...

    "Network interface" 'Network adapter 1' cannot use network 'VMNetwork_VLAN2 (vDSwitch)', because "the destination distributed switch has a different version or vendor than the source distributed switch".

    Even though I get that warning, it lets me proceed. 

    I'm trying to automate this migration and wrote the following PowerCLI Script, however PowerCLI is failing where the Web Client doesn't.

    move-vm : 9/12/2017 3:07:37 PM  Move-VM         The operation for the entity

    "VM1" failed with the following message: "A general system error

    occurred: vmodl.fault.SystemError"

    At E:\ps1\vmware\Migrate.ps1:146 char:2

        + FullyQualifiedErrorId : Client20_TaskServiceImpl_CheckServerSideTaskUpda

       tes_OperationFailed,VMware.VimAutomation.ViCore.Cmdlets.Commands.MoveVM

    The script:

    $migrate = import-csv -path e:\ben\vmware\migrate.csv

    foreach ($row in $migrate) {

    # Read from CSV's Name Column

    $VM = $row.Name

    $Network = $row.Network

    # Shutdown the VM

    shutdown-vmguest $VM -confirm:$false

    # Wait 15 seconds for the VM to shutdown.

    start-sleep 15

    # Perform the vMotion

    move-vm -VM (get-vm $VM) -Datastore (get-datastore "LNvsanDatastore") -destination vmhost1.domain.com -confirm:$false

    # Change the Network Adapter Portgroup

    Get-VM $VM | set-networkadapter -Network Adapter "Network Adapter 1" -Networkname (Get-virtualportgroup -Name $Network) -StartConnected:$true -Confirm:$false

    # Power on the VM

    Start-vm (get-vm $VM) -confirm:$false

    }

    Please help! 

    Thanks in advance!

    Not a real solution, but the only way I got this working in the past, was by creating a "dummy" portgroup on the source and destination hosts.

    And then change the VM (on the source host) to connect to the dummy portgroup.

    Then do the Move-VM, and finally move the VM (on the destination) to the correct portgroup.

    The web client asks you for the source portgroup, the thick client and PowerCLI don't have those options.  Oh well, guess I'll be doing these by hand then.  Thankfully, it's only 10 VMs. :smileyhappy:
