[development] Converting stories to pages

I have mostly pages and a few stories. There is no obvious reasons why the ones that are stories are stories so I would like to convert them to pages. Obviously I can do this by pasting the story stuff into a new page. But then all the links will still go to the old story and I would have to find all the links and fix them. I have not seen any way of finding all the links to a particular node. What woud happen if I just went into PHPMyAdmin and changed the type field from story to page? Would this break anything?
