You have one server, not more than one? You *were* planning on doing full backups first, right? Also, how do you have the server laid out? I've recommended in the past that /home and /opt be separate partitions. Do you have it that way, or are you on one big partition? If so, and you have the space, I'd *strongly* recommend making new partitions and copying everything from those directories to the new ones, then you can do a new install, just so long as you tell it NOT to format them. There's another issue: what the users have running - have you tested to see if RHEL 5.2 breaks them? mark -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
