.. important:: **Redis DB conversion is desirable.**

  Moira 2.3 has some structure changes in Redis DB. 
  It will work fluently out of the box, but we recommend you to run converter once Moira is updated.

  .. code-block:: bash

    moira-cli -update --config=/etc/moira/cli.yml

  .. code-block:: YAML
      :name: cli.yml
      :caption: /etc/moira/cli.yml

      redis:
        host: localhost
        port: "6379"
        dbid: 0
      log_file: stdout
      log_level: debug

  If you would like to downgrade back to Moira 2.2, you should run CLI-converter.

  .. code-block:: bash

    moira-cli -downgrade --config=/etc/moira/cli.yml

  Both cases imply usage of Moira-Cli v.2.3, you can find it on `Release Page <https://github.com/moira-alert/moira/releases>`_.
