Just to clarify before I post, I am running a nulled xF forum FOR THE TIME BEING just until I make my decision on if I will convert or not. I wanted and still want to stay with IP.Board, but my staff are suggesting I make a switch. I'm going to try it out, and if I decide to go with it, I'll buy a license. Right now, I want to do a test conversion to see how things would go if my IPB was converted to xF. If someone could help me out on how to do this, that would be great!
While I can understand wanting to try before you buy, I'm sure you understand that we cannot advocate people using nulled versions by supporting them. XenForo offer a demo of their software http://xenforo.com/demo/ for trying before buying. What I can say is the IPB conversion tool that is also supplied by XenForo works very very well.
Let us know when you decide to go about using XenForo the right way and we'll try to help you with any conversion questions you might have.
