moving root to new hd, anything to watch for?

opensuse 10.3

Just moved everything to a new hard drive. First I setup swap on the new
hd, setup partition(s), and copied all files from old to new. Then I
updated the /etc/fstab, replacing those gnarly disk ids with simple
device names (like /dev/sda2 for example). Then I used supergrubdisk to
install grub and make the new hd bootable. Then I had some problems..
she wouldn't boot. But I figured it out, and also replaced the disk ids
in /boot/grub/menu.lst with simple device names. Now it boots and
everything is working good so far.

Just wondering if the old disk ids might be hanging around anywhere else
and what the ramifications might be? AM I good?
