Have you ever wanted to move a site collection from one content database to different content database? Or if you're not a merger you might be a splitter. Well, neatly tucked away inside the recent security hotfix is the new STSADM command mergecontentdbs. I used this recently with a customer that wanted to nip and tuck some site collections into a better organizational arrangement. I was going to blog on this but then I found this blog post that does a better job than I would do so check it out if you need this kind of functionality.
