Well I suppose you have nightly backups of the data set already?

Maybe just abort the pvmove, let the Friday full backup run, then
on Saturday do a full restore on the new server over iSCSI and
bring it online that way.

I am facing the same issue with a migration of our VM machines
to a new iSCSI setup this year, around 1TB of VMs need to be
fork lifted over and I thought about exotic ways to move it
over, but I think in the end it will be by good ole backup exec
and tape.

Hey! Or maybe just use robocopy from one iSCSI volume to the
other on the Windows side!
