Facebook recently enabled what seems like an obvious tool that allows you to migrate your personal page to a Fan or Business Page. There was no announcement of this feature but it was covered by the always informative InsideFacebook.com
The migration only covers converting your friends to “Likes” so you’ll first want to backup and download all of your photos, videos and wall posts using the recently added download feature found by going to To access the Download Your Information feature, go to Account->Account Settings->Download Your Information and click “learn more”.
Once you start the migration it wipes out your profile, can’t be reversed and unfortunately only allows you to use your current name as the fan page name. Note: Back up your personal profile before starting the migration or you’ll lose everything.
There’s a Facebook Help Center page that outlines the process of migration and here’s the migration tool
There are some reasons why someone promoting a business on Facebook might do this. Actually, promoting a business with your personal profile is supposed to be against Facebook’s Terms of Service, although they’ve loose with enforcing that. Some business only profile users also run up against the 5,000 friends limit and could now benefit from unlimited Likes.
