What would you guys suggest would be the best way to copy forums plus all subforums to a new forum?

I am able to copy the main forum, but the subforums don't follow with it.

Thanks.

Unfortunately you'll probably have to do it one by one, unless you have a plugin/modification or external script to do that.

any one know any script to perform this action? i really need copy all my topics to another installation....
