Page migrated error in Graph API
In my Facebook application, when I query info about a Facebook page through the open graph API, I regularily see errors like (#21) Page ID 290260024371666 was migrated to page ID 122581454447308. Please update your API calls to the new ID when querying the open graph API.
What is this migration? How do pages migrate to another? Is that something that can happen anytime?
Can happen anytime when user merge his fanpage with a other page of similar name. Happens also for Places movie and many other object. Would be nice if the Graph Api would return a extra field with new PageID .
