How to remove duplicated VMs in VMM console

  1.  Move machine to another hyper-v host via Failover Cluster Manager Console
  2.  Get ID of duplicated VM
    Get-SCVirtualMachine -Name "VMName" |fl id,vmid, virtualmachinestate, hostname
  3. Double check working and duplicated machine
    get-vm   -id "ID" | fl id,vmid, virtualmachinestate, hostname
  4. Delete duplicated VM configuration
    get-vm   -id "ID" |Remove-SCVirtualMachine -Force

    Note the -Force option! You are risking to delete your data If you do NOT put -Force.
