Export All Posts in Category to a Different Blog

Hey Gang,
Our entire church site is built on WordPress, and our pastor’s weekly newspaper column is published on the site as it’s own category.

He’s got his own blog now and we’d like to migrate ALL of the previous posts in that category to his blog.

I’m somewhat familiar with phpmyadmin, so if someone could give me the walk-thru, I’d be grateful … anything besides copy/paste all 116+ previous articles from the old blog into the new.

We can’t do a full migration because we only want this ONE category from the source blog moved over into the new, destination blog.
