You can migrate selected Virtual Machines in a Hyper-V Cluster with following script.
That will migrate all virtual machines into target volume.
If target volume is not specified, it will look for best available CSV volume, and migrate virtual machine into that.

# Target Volume
$TargetVolume = "Volume1"
 
# Create VM Array
$VMArray = New-Object System.Collections.ArrayList
$VMArray.Clear();
 
$AddArray = $VMArray.Add("VM01")
$AddArray = $VMArray.Add("VM02")
$AddArray = $VMArray.Add("VM03")
 
# Get Cluster Nodes
$ClusterNodes = Get-Cluster | Get-ClusterNode
 
foreach ($ClusterNode in $ClusterNodes)
{
	# Get All Virtual Machines
	$VMs = Get-VM -ComputerName "$ClusterNode"
 
	foreach ($VM in $VMs)
	{
		# Get VM Information
		$VMName = $VM.Name
 
		if ($VMArray.Contains($VMName) -eq $True)
		{ 
			Write-Host " "
			Write-Host "Working on $VMName .."
			Write-Host "Hyper-V Host: $ClusterNode"
 
			if (!$TargetVolume)
			{
				# Get Volume Information
				$Volume = ((Get-ClusterSharedVolume | Select -ExpandProperty SharedVolumeInfo | Select @{label="Name";expression={(($_.FriendlyVolumeName).Split("\"))[-1]}},@{label="FreeSpace";expression={($_ | Select -Expand Partition).FreeSpace}} | Sort FreeSpace -Descending)[0]).Name
			}
			else
			{
				$Volume = $TargetVolume
			}
 
			# Move Virtual Machine
			Move-VMStorage -ComputerName "$ClusterNode" -VMName "$VMName" -DestinationStoragePath "C:\ClusterStorage\$Volume\$VMName"
 
			Write-Host "Done."
		}
	}
}

This script should work even if you have pass-through disks on virtual machine or virtual hba.
