That's actually the feature I've been looking forward to. As I moved vom Android to iOS, I lost _all_ message histories from all messenger apps that use E2EE (Signal, WhatsApp, Threema, etc). The only one that "just worked" was Telegram due to not being encrypted. WhatsApp had a migration app that has to be done when setting up the iPhone, but it failed due to some bug. Signal had backups, but they didn't seem to be compatible between different OS versions.

I'm curious about that, has this been tested by someone who "steals" the phone, and tries to migrate before the actual phone owner even realizes?

you need to be able to unlock the phone and then you need the Signal PIN code for this.
