Upgrading from Mayan EDMS 3.5.x


Supervisord must be upgraded to version 4.2.2. See troubleshooting section: After upgrade to version 4.1

  1. Stop supervisord:

    sudo systemctl stop supervisor
  2. Make a backup of your supervisord file:

    sudo cp /etc/supervisor/conf.d/mayan-edms.conf /etc/supervisor/conf.d/mayan-edms.conf.bck
  3. Make a backup of your database:

    Use the respective backup command for the database:

  4. Upgrade to the latest pip version:

    sudo --user=mayan /opt/mayan-edms/bin/pip install --upgrade pip
  5. Remove deprecated requirements:

    sudo --user=mayan curl --output /tmp/removals.txt \
    && sudo --user=mayan /opt/mayan-edms/bin/pip uninstall --requirement /tmp/removals.txt --yes
  6. Update the Mayan EDMS Python package:

    sudo --user=mayan /opt/mayan-edms/bin/pip install mayan-edms==4.4.2

    the requirements will also be updated automatically.

  7. Update the Redis configuration to serve at least 3 databases:


    databases ...


    databases 3
  8. Restart Redis for the changes to take effect:

    sudo systemctl restart redis
  9. Edit the config file at /opt/mayan-edms/media/config.yml:




    LOCK_MANAGER_BACKEND: mayan.apps.lock_manager.backends.redis_lock.RedisLock
    LOCK_MANAGER_BACKEND_ARGUMENTS: {'redis_url':'redis://:mayanredispassword@<IP address of Redis server>:6379/2'}
  10. Update the supervisord configuration file. Replace the environment variables values shown here with your respective settings. This step will refresh the supervisord configuration file with the new queues and the latest recommended layout:

    sudo --user=mayan MAYAN_MEDIA_ROOT=/opt/mayan-edms/media/ \
    /opt/mayan-edms/bin/ platformtemplate supervisord | sudo sh -c "cat > /etc/supervisor/conf.d/mayan-edms.conf"
  11. Edit the supervisord configuration file and update any setting specific to your installation:

    sudo vi /etc/supervisor/conf.d/mayan-edms.conf
  12. Migrate existing database schema and static media files with:

    sudo --user=mayan MAYAN_MEDIA_ROOT=/opt/mayan-edms/media/ \
    /opt/mayan-edms/bin/ performupgrade
  13. Start supervisord:

    sudo systemctl start supervisor
  14. Clear the browser cache to avoid loading old web assets.

The upgrade procedure is now complete.
