How to export data from a imageboard--

--so I can import it on a new imageboard? (rest of Subject)

Well, the title pretty much sums it all. I have a buggy, unused imageboard, and I was able to set up a good flawless (not actually, it's Kusaba lol) imageboard, but the old imageboard has about 1337 posts, and I can't be bothered to repost the whole thing, and I was wondering if there is a way to do it, any help will be appreciated.

Yeah, it's not going to be a busy imageboard, but it's a somewhat official imageboard of a website, official yet casual
Okay.
besides, I like those features to be used.
Why? If you need to make an announcement, even on a single board, just insert it in the top header. Public banning is also silly (even on a site like 4chan), since it just draws stupid attention to some asshat getting banned.
