How to Test the PostgreSQL Upgrade:

1. Build and start the updated Docker containers:

   docker compose up --build

2. Restore the legacy backup:

   • Copy the legacy backup file into the backup container:

     docker cp ../daisy_test.tar.gz $(docker compose ps -q backup):/code/daisy_test.tar.gz

   • Execute the legacy restore script inside the backup container:

     docker compose exec backup sh /code/scripts/legacy_restore.sh /code/daisy_test.tar.gz

   • Remove the backup file from the container:

     docker compose exec backup rm /code/daisy_test.tar.gz

3. Apply Django migrations:

   docker compose exec web python manage.py migrate
