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.

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

You can migrate selected Virtual Machines in a Hyper-V server 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.
