Move a VM disk to an other hyper-v server

Hello,

Does anybody know the maximum size for moving a vm to another hyper-v host. 

I shall explain what i want to do.

I have some vm's with disk size of approx. 200 gig. I have moved these vm's to a Hyper-V cluster with no pain and gain.

Now there is one vm with a disk size of 1.3 tb, if i want to move this vm i get an error.

So my question is therefor is ther a maximum "move size" for VM's

Thanx in advance

Robert
