That's why I'm rebuilding old1->new1, pull old1 when finished, rebuild new1->new2.  So if I lose a new disk off the bat I should hopefully have a working copy, barring restoring backups.  Which, by the way, is a PITA when the failed server is the dom0 and the previous admin set it up such that each virtual disk is a logical volume under LVM.
