One advantage is that I didn't really bother with the ports on that server, I 
rolled my own apps as I wasn't totally up with the ports system at the time, 
just seemed easier until I go the hang of it, so I probably would go for a 
fresh install of ports and get the latest versions of software installed that way.

The server is used for web hosting so I only really need to save out a few 
config files for virtual hosts etc. and the email directories.

It's sounding as though it might be easier just to have an hour or two of 
downtime late one night and do a fresh install...
