Use Hyper-V Live Storage Migration to Move Virtual Machines

Q: How can I easily move all the virtual machines in my cluster to new storage?

A: The Hyper-V Live Storage Migration feature allows you to easily move a virtual machine's (VM's) storage to a new location without affecting the VM's availability. You can use a few lines of PowerShell code to move every VM in a cluster to a new storage location:

#Get list of all virtual machines running as cluster resources$VMstoMove = Get-ClusterResource | Where-Object {$_.ResourceType -eq "Virtual Machine"} | Get-VMforeach ($VM in $VMstoMove){    write-host $VM.Name    $newpath = "C:ClusterStorageVM01" + $VM.Name    Move-VMStorage -DestinationStoragePath $newpath -VM $VM}

You need to change the value of $newpath to match your new path.
