When Xenforo will have a direct mybb forum converter? It will be really easy for every mybb users then who wanted to convert. I know xenforo staff is helpful with it and can help us in the conversion but my point is it will be a better thing..
Unfortunately, unless someone decides to write one as an add-on, it's unlikely we'll get a direct convertor any time soon. However, a few of us (Jake Bunce ) are very experienced at two-step conversions and can do so without any loss of data. It might not be the neatest or most direct way of doing it, but it does work!
