stupid newbie question: i have a redhat 7.x system i updated with yum for the first time last night, and it seems like it was a success, with lots of packages being updated. the system still works :-) now i'd like to 'move forward' if possible, to packages from redhat 8, then 9, then fedora 1 and 2. is that something one can do solely with yum? if so, how would i do it? would i just add some of the appropriate public yum repositories to my /etc/yum.conf and type 'yum update'? or would 'yum upgrade' be more appropriate? i've never used the 'upgrade' command before. thanks, mike (i haven't subscribed to this mailing list yet)
