Facebook’s tool to convert a personal profile to a page appears to be down.

Earlier this week, Facebook released a one-way tool that would let users convert their old profiles into pages. The tool was designed to be convenient for businesses and to bring more users in line with the site’s Terms of Service, which say that you can only maintain a profile for an individual person.

Now the feature may have been disabled, says Mashable’s Christina Warren. And with good reason.

On Thursday, Warren decided to try the tool and outlined her migration in a blog post. In short, it was a mess. Not only did Warren lose much of her personal information, she also lost her hard-fought username, almost all the functionality of any site or program that connects through Facebook and most of her ability to set up a personal account.

Warren was able to contact someone at Facebook who was able to reverse the changes, but told others to proceed at their own risk.

“If it’s for anything other than TOS compliance, it’s probably not a good idea to move forward,” she warned.

(Post Co. Chairman and Chief Executive Donald E. Graham sits on Facebook’s board of directors, and the newspaper and many Post staffers use Facebook for marketing purposes.)
