OK, I think I have reached a good time in my work schedule to upgrade to Panther, possibly over the weekend. I have also decided, based on various postings in these forums, that a clean install (versus an "upgrade" install) is probably the best choice. So my question is: for the least disruption of work, which directories do I need to back up? Should I back up my entire home directory, or is that overkill? And are there other (system) directories that I might need to backup as well? Any advice from more experience Mac OS X users is welcome.
