I'm next to certain it does. It supported upgrades from whenever Anaconda appeard (5.x or so I think) right up to RHL 9 - even skipping releases, and upgrades to newer Fedora Core work. I don't see why upgrading RHEL 2.1 to 3 or 4 would not work. There might be some manual work to do, replacing dropped packed (eg imapd) with newer (eg cyrus-imapd). > > so I can't imagine it'll be supported in anything from 4 -> 5. and I'll be fairly surprised if it's not:-) One thin I have in mind is to try to upgrade RHL 7.3 to Centos 3 or 4 at some point. I fully expect to apply a little force in that case; that is what it's for (not a supported upgrade but probably will work). -- Cheers John -- spambait 1aaaaaaa at coco.merseine.nu Z1aaaaaaa at coco.merseine.nu Tourist pics http://portgeographe.environmentaldisasters.cds.merseine.nu/ Please do not reply off-list
