Ugh. Time to upgrade my server

I'm still running Fedora 8 on my server, and haven't had a compelling 
reason to switch.  Until now.  It looks like atrpms no longer supports 
Fedora 8.  I hope to load Ubuntu 9.04 tonight.

One question: If I feel like pressing my luck and converting over from 
MBox format to Maildir for Dovecot/Postfix (something I've been meaning 
to do for a LONG time), is there an easy way of copying over the mail? 
I found http://www.gerg.ca/hacks/mb2md/
but it's from 2002, and that makes me nervous.
