I know this might be the wrong forum, but I didn't want to post this in the Presales forum since... well, I'm not presale. Anyways, I just have a question about upgrading. I don't understand how to. Yes, I've read the XenForo guide, but I'm still afraid of the way some of the things are worded on there. Do I OVERWRITE everything completely with the upgrade files, or am I supposed to do something else? Won't data be lost if I am supposed to completely overwrite the old files?
