Upgrading OS versions is always risky. They're usually successful, but
there are times when bad things happen.

The most important thing is to have a backup of your data BEFORE you try
the upgrade. The most important things to back up are the users' home
directories and any additional software you may have installed (e.g.
Oracle and that sort of thing).

It doesn't matter what the backup media is, as long as it's reliable.
I use both tape and a second hard drive. The hard drive makes it easier
to get at the backup data directly rather than having to restore from
the sequential-access tape. I often do both (back up to tape, then
back up to hard drive), then archive the tape.

Rick,

Thanks for the quick reply.  

For some reasons, I have the assumptions that the packages for AS 2.1 is different from packages in AS 3.0.   I have once tried to use rpm -Fvh from AS 2.1 packages with AS 3.0 packages and got errors while doing so.  That's when I have the assumption that some packages use for AS 3.0 are different from packages for AS 2.1 and they are not compatible.  Is that assumption incorrect?


Thanks,

cindyw
