I have done it that way a long time ago - not the greatest fun but it works 
well enough... 
The things I can think of that you need to worry about to get a booting system 
are:

1) grub.conf (root entries, splash image)
2) scsi driver in initrd for your controller (mod /etc/modules.conf with the 
driver for your scsi crontoller and rerun mkinitrd before you move to the new 
hardware) 
3) devices will be different (modify /etc/fstab)

That should give you a bootable system - the rest of the drivers, x and so on 
you can do through kudzu and system-config-*


Anyway, I'd just reload the box...
