Is there or will there ever been a converter for moving from Invision Power Board IPB 1.3.1 to MyBB 1.2? I have a really old forum I need to get changed into something else and would like to make that MyBB.
I may be wrong but I doubt that older versions of BBSs will get added to the list of supported softwares, as there would probably be a low number of people using them, and from what I understand, they're not easy to write. What you could do is find a BBS which you can convert to MyBB from, that also enables you to convert from IPB 1.3.1, so, just as an example, IPB > phpBB > MyBB.
