Is there a way to turn a post into a page (and vice versa) without transferring the content?

Hi
I'm wondering if there's an easier/faster way of turning posts into pages (and vice versa) without transferring it over manually.

I'm wondering if a programmer could go into the backend and edit the content type in some sort of backend table... OR, if this is something something could tell me how to do myself.

Thanks so much!
