Not every release includes a database upgrade script but if there is one, it would be in the conf directory under OPENEMPI_HOME. Upgrading to the 4.2.0 release from 4.1.x requires that you run the script update_database_schema-4.2.0.sql but depending on the current minor version of 4.1 that you are upgrading from, there may also be some upgrade scripts to bring your 4.1.x version up to the latest version in the 4.1 stream. For example, if you are currently at 4.1.3, you must also run the upgrade script for the 4.1.4 release.
