In response to so many questions about porting/migrating and merging of Profiles, I have noticed from the G+ Settings >> Data Liberation that "...Google lets you save a backup of your photos, profile information, contacts, circles, stream posts, and Buzz posts to your computer...". My assumption is that if you can save this data that you must be able to import it as well. The question which hopefully +Christian Oestlien
can answer is whether such an import would be allowed into a GApps Profile when available. It does create a gray area in terms of duplication though. Consider that if you download all of the aforementioned data from your Google Profile and then import it into your Google Apps Profile, you have duplicate photos, streams, circles, etc.
