I upgraded two systems ok and my laptop will be next.

I downloaded the ISO because I had more than one machine to upgrade and thought it would be nice to have the CD around for sharing with newbies.

I ran "sudo bash /cdrom/cdromupgrade" and it asks if you would like to use the network which I thought was cool because if there happens to be slightly newer packages out it can incorporate them immediately. Great.

I expected it to whiz through and pick up most deb's from the CD, but the curious thing is that it seemed to prefer to download them. I have no idea why, but the upgrades did work.
