let me guess,  This is a _production machine_ and you are planning an
upgrade.  Have you paid the life insurance?  In other words, have you
done a backup so that if something goes wrong you can recover?

I have never done an 'upgrade' install.  However, there are many who
have, and many messages just after FC5 came out about 4 months ago
concerning both successes and failures.  You may want to check the
archives from the March - April time frame to see what others had to say
about it.
