Database Upgrades
If using an external database server, such as MySQL, a DBA must manually perform the database schema update. In most cases an upgrade requires re-running the initialization script which will drop the current tables and re-create them. The initialization can be found in the github repository.
If you want to use an external database other than one listed in the repo please open an issue on the github issue tracker as an initialization and dialect properties file will likely need to be created.
