Maybe try a SuperGrub Boot Disk (or USB drive) if you are using GRUB. I would probably install on a minimal system on the new disks so they are bootable, create the new volumes, rsync, move to the desired machine and boot with the SuperGrub Boot Disk if the machine didn't just boot from the drives on it's own.
