well u can buy ad removal where they simply hide the ad from showing on the page.
But if u buy the database, (make request via support ticket) ud just have the sql file, u woulkd then need your own hosted copy of ipb 1.3 to install it on realy, athogh certain changes in how the boards work cause a few problems such as polls made before the change wont work correctly etc, but most the db struture is the same, so fully useable, its how i moved thybag from if, athogh i had to deledt 10000 posts so i could fit in to the price range, as the more posts the bigger costs etc
