        However, we've discovered an existing SQLite database in {{ matrix_mautrix_telegram_sqlite_database_path_local }}.
        It appears that you've been using this bridge with the SQLite engine until now.
        To continue using SQLite, opt into it explicitly: add `matrix_mautrix_telegram_database_engine: sqlite` to your vars.yml file and re-run this same command.
        Alternatively, to migrate your existing SQLite database to Postgres:
        1. Stop all services (`ansible-playbook -i inventory/hosts setup.yml --tags=stop`)
        2. Import the SQLite database into Postgres (`ansible-playbook -v -i inventory/hosts setup.yml --tags=import-generic-sqlite-db --extra-vars='sqlite_database_path={{ matrix_mautrix_telegram_sqlite_database_path_local }} postgres_connection_string_variable_name=matrix_mautrix_telegram_database_connection_string'`)
        3. Re-run the playbook (`ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start`)
