I originally signed up into our dropbox team account with my personal account. At some point dropbox emailed me and effectively said "hey, not a great idea to have your personal account merged with your team account." They had an interface for me to select which files were personal files and split those back out into my personal account. Overall it was a pretty smooth process, since at the time I had pretty much accepted that there was no going back.
