Over the past couple years, lots of people have been doing yum upgrades from one version of RHL to the next. People have been known to do 7.3->8, 8->9, 9->FC1, etc. Now, little effort is made by the OS developers to make this smooth, so you can expect a little trouble. Basically, it involves changing your repos, possibly upgrading *-release manually, and then doing a 'yum upgrade'. It's usually a bit iterative - you often have to try it, see what packages cause trouble and remove them (yum erase), and then try again. I've never had it take more than about two cycles of this, though. Now, the other thing: you can also do a something like (untested - I don't remember the syntax I used): box1% rpm -qa > packagelist box2% xargs yum -t install < packagelist (-t basically means "don't complain if it's already installed") -Michael -- Michael D.
