Thanks for the info. My old computer is over 5 years old now, so I did not want to use Migration Assisstant and wind up with all the clutter and junk that accumulates over that time.
I did not know that I could use just the latest upgrade disk for Aperture. I seem to recall trying a few years ago and having to get out all my old disks. I'll try it as soon as I have the chance.
