My tests with #diaspora import #migration are running well.
If you want (or need to) move from your pod, I have good news. At least on my development machine I now can import migration files (the zipped json, you can download from your settings menu) as well as the zipped #photos file.

Don't hold your breath, but in the next days I will deploy an early test available for everyone to #societas.

@Fla has a nice new registration formula in the makes that will lead you from new registrations to the migration page. (Still need to adapt this)
