i did the board conversion that you mentioned to show proof of concept. also even grabbed your header ads and duplicated the main style.
it was by no means an easy thing (evidenced by everyone to date having tried and failed), but i can say that the importer i started from is one in the same as yours.
there are some _very_ special things to consider when importing such a large forum. the first thing is actually the first forum that has 1.13million posts alone
also, your server itself has issues that cause the importer to puke or require a lotta hand holding.
so, yes you can give it a go on your own and more power to you if you get it done!
if you do, then i congratulate you as being the 2nd one to get it to work.
your forum is very special in many ways. 1 and a half million posts on bows and arrows being just ONE
good luck to you
