How to transfer ownership of a facebook page to another profile?

[CofeeNate]

"Like" the page from your profile. Then use her profile to make you and administrator for the page. Then you will have the same level of permissions as her account. Now, you can remove her as an admin.

Moving forward, when you have a new employee that is going to be administrating the page, you can add them as well. The new control panel allows you to assign roles to the different admins of the page. You can limit the powers of your subordinates, so they don't go rogue. By doing this, you won't have to fear that a disgruntled employee will take your page hostage.
