+
+Update the supervisord configuration file. Replace the environment
+variables values show here with your respective settings. This step will refresh

+    MAYAN_DATABASE_PASSWORD=mayanuserpass 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 > /etc/supervisor/conf.d/mayan.conf
+
+Edit the supervisord configuration file and update any setting the template
+generator missed::
+
+    sudo vi /etc/supervisor/conf.d/mayan.conf
+
+Migrate existing database schema with::
+
+    sudo -u mayan MAYAN_DATABASE_ENGINE=django.db.backends.postgresql MAYAN_DATABASE_NAME=mayan \
+    MAYAN_DATABASE_PASSWORD=mayanuserpass MAYAN_DATABASE_USER=mayan \
