Converting my IP Bard to Wordpress

Question

I have a Invision Power Board forum and I am seriously thinking to change it and convert it to a Wordpress blog/news site

since I have a lot of threads, and post replies my question is can I convert it too just Wordpress without adding bbpress plugin to Wordpress? there I a paid service that could do teh conversion but into bbpress in Wordpress I just want the thread replies to appear in worpress as comments on each post
