Problem

When you upgrade or replace your phone, you’ll want to transfer your Signal account, messages, and media. Since Signal doesn’t use cloud storage, transfers must be done using local backups (Android) or encrypted device-to-device migration (iOS).

Solution

Signal provides built-in tools for secure transfers depending on your platform.
