    Hi @lrj650 ,

    As far as I know this won't work, Microsoft Virtual Server uses VHDs and not VHDX which are newer virtual disk files. If you mean transfering a .VHDX file from one Hyper-V server to another Hyper-V server, yes this is possible to do.

    Hello @lrj650

    In my experience you can use .vhdx if you are going to attached same or Higher version of Hyper-V server Data disk ( additional disk ).

    You need to just turnoff existing VM and copy the .vhdx file to another Hyper-V node and attach to VM.

    Hello again @lrj650

    Yes, it will work, if you turn off-detach-copy, but the main issue with copying or cloning a VHDX is the "Disk Signature Collision", meaning that both drives will have identical ID and this will be problematic depending on the usage that you will give them.

    All in all, is better to detach the drive and, if Fixed Sized, to leave it detached (as a Parent), Sysprep it and then create 2 separate Differencing disks for your VMs. This will allow to use the current information in the two machines, but each one will keep track of their own changes in their own disk.

    Hope you find this useful.
