updateDb – the task of the CubaDbUpdate type which updates the database by executing the corresponding scripts. It is similar to the createDb task, except that the dropDbSql and createDbSql parameters are omitted.

You can also set the parameters described in createDb (except dropDbSql and createDbSql) explicitly.
