### Upgrading Arches
1. You must be upgraded to at least version 6.2.0 before proceeding.

2. Upgrade to Arches 6.2.7

    If using a virtual environment, be sure to activate it:

        pip install --upgrade arches==6.2.7

3. Update your Javascript dependencies

    Navigate to the directory with your project's package.json file. This is located in the same directory as your project's settings.py file.
    Ensure your arches dependency points to either `#archesproject/arches#dev/6.2.x` or `#archesproject/arches#stable/6.2.7`.\
    For example:

        "dependencies": {
            "arches": "archesproject/arches#dev/6.2.x"
        }
    
    If upgrading from version <= 6.2.3 run:

        yarn install

4. If you are running Arches on Apache, be sure to run:

    ```
    python manage.py collectstatic
    ```
    and restart your server.
    ```
    sudo service apache2 reload
    ```

5. If you are running Celery, you should also restart your Celery worker(s). The process for doing this depends on how Celery is being run.

6. **Important**: As of version 6.2.6, Arches supports rate limiting on authentication endpoints to help protect your system. In order to fully take advantage of this feature, you must have  your default cache configured using Memcached or Redis. See the Django docs more information on [cache configuration](https://docs.djangoproject.com/en/3.2/topics/cache/#setting-up-the-cache).
