Send forum to archive

[Bigguy]

Ok, I hope I explain this right. On my forums I have created a board that no one can see called "archives" I send all topics there I want to safe, sort of like pruning. If I wanted to, how would I send a whole board to the archives board. Like if I wanted to archive my "feedback & suggestions" board on my forum is there a away I could do that like sort of send a board to an archive depot or spot
