I finally achieved a goal and got a copy of the forum running on my local machine. This means I can run through all the forum upgrades locally and make sure they are working before upgrading the site. We are quite a few versions behind now, as we are on beta-0.9 and the latest is beta-0.13. Sadly you can’t just go from 9 to 13, you need to install all the updates in between individually. Oh well, at least I can take my time with it now.
