Pairing a new device without losing a single chat
Linking a device used to start it empty. I made Verus pairing carry chats, contacts and groups across, sealed inside the pairing itself.
What I tried
The first version of pairing shared an identity with the new device, not a history. People expect their conversations on both.
Why I chose differently
Device linking was built to share keys. Carrying chats, contacts and groups was the natural next step.
What I chose
Pairing now carries chats, contacts and groups across inside the same encrypted exchange. The receiving device keeps what it already had. I took a backup first, then paired for real: every message, contact and group arrived and the Mac lost nothing.
The principle
Test a migration on the device you would least like to lose, with a backup taken first.
