[jboss-user] [EJB 3.0] - How to migrate data when entity model changes

I would like to know various ways to easily migrate data generated in tables, created by JPA, provider from an old object model to tables created using a newer object model. Entity relationships may have changed in the new model, some fields added and a few others removed. It would be very cumbersome to write SQL directly against the generated tables to extract and insert data! Are there any tools available to do this?
