Merge Facebook applications into one

Facebook just announced support for multiple app domains (read the post here) in their applications. We're having multiple applications since our website is localized, but now, with this new feature, we'd like all these applications to be merged into just one.

Is there any way to do this 开发者_运维知识库at this current moment?

Alternatively we'd have to ask all of our thousands of users to re-connect with Facebook once again just to get them all on just one single shared application.

There's no way to do this; you could slowly migrate users to the 'new' / 'primary' app - bearing in mind users will have to go through the auth dialog again
