I'm moving my xenforo forum between hosts. I already have the MySQL DB copied over, and am currently queuing all the old xenforo files to download and reupload at the new host. Curious though, the config is set to read from the old database with the old database name and the old password, etc. How can I change all of that? Or, maybe a better question is, is there some sort of writeup or guide for transferring xenforo between hosts?
