[olug] Upgrading to FC4 from FC3

[A-Wal]

Hello,

    This is a n00b question, I know, but I really don't know the 
answer.  If I download the FC4 ISOs and select upgrade, will it save my 
email settings in Thunderbird after the install?  I'm actually going to 
wipe my Linux partitions and reinstall from scratch, but it's just a FYI 
for future upgrades.  I currently have several partitions, with several 
Linux flavors, and will be consolidating them all into a single FC4 
install.  Sure, I can probably remap the other partitions into my FC3 
system under new directories, but I consider that a sloppy hack when I 
can just do it right in a day anyway.  The other question is sorta 
related.  What Thunderbird data files do I need to copy over to my new 
system to restore all my settings and filters?  That's really the only 
data I would like backed up and restored on the new system.

Thanks
