I've done just what you suggest. I had to boot the system b with the install cd and do a repair system and it was fine. Some items to look out for: 1) network cards might not be configured correctly, or be configured with the same ip so boot system b without a cable attached to fix the nic 2) fstab might need to be fixed due to how the disks are referenced. IE device name, UUID, or label 3) /boot/grub/menu.lst might need fixing also because of the nameing conventiion of the disks. You also might want to look at the clonezilla livecd to clone from on system to the next. That also works fantastic. -- Brian Millett - [ Kosh, "Deathwalker"] "A stroke of the brush does not guarantee art from the bristles."
