I have an old site of a friend that we haven't touched in a while... turns out it's running 1.1! I didn't realize I couldn't upgrade from 1.1 straight to 1.6, and I already overwrote the site with 1.6. I still have the original backed up if I have to start from there...
but can someone tell me the best way to upgrade the 1.1 site up to the current version? do I have to go down the line one at a time? or can I start at say 1.3 and jump to 1.5 then 1.6 or something like that?
many thanks in advance!
