migration

I am trying to migrate a VM which is using two pass through disks from a legacy Hyper-V Cluster to a new R2 cluster. The migrated VM cannot use the pass through disks though. The guest OS (2008 R2) doesn't seem to like the disk and eventually tries to format the disk instead of mounting it.

The migration process I have been using for all my VMs is to export the VM to a new lun, then add that new lun to the new cluster, importing the vm off it in the hyper-v console, then making it highly available. I assumed I could do the same thing and just add the two pass through disks to the new cluster and then attach them inside Hyper-V.

Is there a process I need to follow to migrate pass through disks that does not involve setting up new Luns and robocopying the data over?
