So I decided to change over to XenForo for a project I am involved in and was using SMF 2 for. I have worked with SMF 2 for several years now and figured I may as well do it right and write an importer. So here is the incomplete importer which I will finish when I get free time or need it again... TODO - import polls - import moderators - import permissions per board - other small settings here and there - lots of other stuff that I can't think of, it is far from done Importing polls isn't in yet as I never needed it, same with moderators and some other features it is missing. I have also barely tested it so be careful! I am not at fault if your server dies a horrible death. I am not going to give support here however if you find a bug I'll try and find time to fix it. User merging isn't supported and I don't plan to support it. This is designed to be used on a fresh install of XenForo. If there are any users that 'collide' then it will fail. Installing Upload the attached file and then install the addon by going to admin -> install addon and running SMF2Importer.xml. Go into tools -> import external data and see how you go from there. No promises but I hope it works for you. I also don't take into account charsets as of yet. Basically I had to take a heap of shortcuts to get what I needed done. I will hopefully finish it one day if there is any demand for it.
