Upgrading from 1.26.1, quick question about encryption key

[eliluong]

Hello, I have been running an old version of Teslamate for quite a while (1.24.2). After making a backup of database, after adding ENCRYPTION_KEY to the docker-compose file, is that all that is needed to get it working? I assume it may prompt me to add new access/refresh tokens. Thanks.

Here is a solution.

1. make a backup of the database, then shut down all these containers associated with teslamate
2. modify docker compose file with new images: teslamate/teslamate:1.27.4, postgres:15, eclipse-mosquitto:2.0, etc; also add the encryption key for teslamate
3. follow instruction to upgrade postgres
4. then follow instruction to restore database. I did something slightly different: run docker compose up database to start up only the postgres container, then restore (had teslamate container stopped so it would not write to postgres). you can verify it all worked by running just the database and grafana container.
5. let docker compose start all four containers. and everything worked, including new tokens, without intervention (I think).
