Make a backup of your supervisord file:

sudo cp /etc/supervisor/conf.d/mayan-edms.conf /etc/supervisor/conf.d/mayan-edms.conf.bck

Update the supervisord configuration file. Replace the environment variables values show here with your respective settings. This step will refresh the supervisord configuration file with the new queues and the latest recommended layout:

sudo -u mayan MAYAN_DATABASE_ENGINE=django.db.backends.postgresql MAYAN_DATABASE_NAME=mayan \
MAYAN_DATABASE_PASSWORD=mayandbpass MAYAN_DATABASE_USER=mayan \
MAYAN_DATABASE_HOST=127.0.0.1 MAYAN_MEDIA_ROOT=/opt/mayan-edms/media/ \
/opt/mayan-edms/bin/mayan-edms.py platformtemplate supervisord | sudo sh -c "cat > /etc/supervisor/conf.d/mayan-edms.conf"

or:

sudo -u mayan MAYAN_DATABASES=\"{'default':{'ENGINE':'django.db.backends.postgresql','NAME':'mayan','PASSWORD':'mayandbpass','USER':'mayan','HOST':'127.0.0.1'}}\" \
MAYAN_MEDIA_ROOT=/opt/mayan-edms/media/ \
/opt/mayan-edms/bin/mayan-edms.py platformtemplate supervisord | sudo sh -c "cat > /etc/supervisor/conf.d/mayan-edms.conf"

Edit the supervisord configuration file and update any setting specific to your installation:
```
sudo vi /etc/supervisor/conf.d/mayan-edms.conf
```

Migrate existing database schema and static media files with:

sudo -u mayan MAYAN_DATABASE_ENGINE=django.db.backends.postgresql MAYAN_DATABASE_NAME=mayan \
MAYAN_DATABASE_PASSWORD=mayandbpass MAYAN_DATABASE_USER=mayan \
MAYAN_DATABASE_HOST=127.0.0.1 MAYAN_MEDIA_ROOT=/opt/mayan-edms/media/ \
/opt/mayan-edms/bin/mayan-edms.py performupgrade

or:

 sudo -u mayan MAYAN_DATABASES="{'default':{'ENGINE':'django.db.backends.postgresql','NAME':'mayan','PASSWORD':'mayandbpass','USER':'mayan','HOST':'127.0.0.1'}}" \
 MAYAN_MEDIA_ROOT=/opt/mayan-edms/media/ \
/opt/mayan-edms/bin/mayan-edms.py performupgrade
