title: JPA/Hibernate support for migration?
body: <p>I'm currently working on a desktop application using JPA/Hibernate to persist data in a H2 database. I'm curious what my options are if I need to make changes to the database schema in the future for some reason. Maybe I'll have to introduce new entities, remove them or just change the types of properties in an entity.</p>
  
  <ul>
  <li>Is there support in JPA/Hibernate to do this?</li>
  <li>Would I have to manually script a solution?</li>
  </ul>
