Migrating blog content from one multisite to the other selectively

So I have a WP multisite install where our client made changes over on a staging site. But now we need to bring the changed tables back in.

I know how to move sub sites with a clear ID (wp_#_) but this is blog ID1.

So i brought in ALL none site specific wp_ tables but nothing. So where is blog id #1 data saved if there is no wp_1_ in my 10k table DB?

thanks!
