I downloaded lucid's beta-1 cd for testing out a fresh install, and all went well.

Now that I have the cd, is there a way to upgrade a machine that already has karmic up to lucid by using the CD? I'd prefer not to put additional load on the download servers (and my pipe) if I've already got the CD. And, I expect to upgrade a couple more machines. I figured I'd save bandwidth if I could.

Thanks!
