Hi experts,

today we exerienced a problem while copying an expted VM from one Hyper-V to the other.
From the destination server I started copying the 30GB export via administrative share \\servername\c$ to the local SSD storage C:
After a while the destination hyper-v server stopped responding an dthe VM which already ran from C: also stopped responding.
This happened due to very bad I/O Performance.
Because of that it not seems to be possible to copy any files to a hyper-v storage without influencing the other VMs on that host.
Is there a tweak that makes copying possible?
What is the recommended way to copy a VM to a hyper-v server across the network? The same server ran ESXi before and there we never experienced such problems.

Thanks for your replies.

Best regards
