Wow, maybe as a side effect users will be able to migrate between Android and iOS without losing their message history.

Seriously, why is the migration protocol completely different on the two platforms?

Hi there, Signal dev here. The new backup format is indeed cross-platform. I've successfully restored backups on an iPhone, we're just stabilizing things :)

If you're curious, the reason that Android's current local backups aren't cross platform is because it was made a long time ago, and it's literally a dump of all the sqlite statements that can be used to recreate Android's sqlite database (encrypted with a strong, random, local key). So not the most portable!

But this new thing is all cross-platform, and in the near future we'll even be making our local backups cross-platform.

Will you guys ever ship an update that allows me to use my Signal iOS install that had a partially-broken migration from an older device? I was able to receive/read messages, but couldn't send. I tried to re-register but now my client is completely broken and crashes when I enter the registration verification code I get via SMS.
