Hi,

I saw EclipseLink 2.5 support schema generation feature of JPA 2.1. But I cannot find something that equivalent to "<property name="eclipselink.ddl-generation" value="create-or-extend-tables" />" in 2.4.
"create-or-extend-tables" will create tables if not existing, and extend table if I add new column.

If I would like to update to 2.5, how can I do that as 2.4?

JPA 2.1 does not provide an "extend" option. In EclipseLink you can use the "create-or-extend-tables" option with the new JPA 2.1 schema generation properties, or you can continue to use the EclipseLink "eclipselink.ddl-generation" property.
