Hello xenForo support, I was trying to upgrade my XF 1.1.5 forum to version 1.2.3 today, but it took about 40 minutes to load and in the end gave me a 500 internal server error. After that situation I just decided that a clean install would be better, and import the data from my 1.1.5 board to my 1.2.3 board. I can't seem to find out how to do that. I have tried installing the the board on the database that had the old data, but that didn't work. I have a backup of the database, if needed. I would like some assistance to help me import my 1.1.5 posts, members and all data over, is this possible from my 1.1.5 board to my 1.2.3 board? Will database be needed? Please help!
