This process will convert the currently existing database into a backup owl file stored in app/protégé/data/Protégé_xx/<PROTÉGÉ INSTANCE>. This file can then be used to be converted back to an OWL / RDF database, creating new tables and indexes to reflect any database related code / schema changes. The same owl file can also be used to update Dev, QA, and Stage.

• Advertise that the production server will be going down.

• Run 'sh shutdown_protege_server localhost:2633.'
