1. Create a backup

2. Stop all TeslaMate containers

   docker-compose down
   

3. Delete the database volume. Be careful, this will delete all your previously recorded data! Make sure that your backup can be restored before you start.

   docker volume rm "$(basename "$PWD")_teslamate-db"
   

4. Change the postgres version in docker-compose.yml and start the container

   database:
     image: postgres:xx
   

   docker-compose up -d database
