Gail Badner commented on HHH-5814:
----------------------------------

Dave, what Hibernate version are you using? Why are you setting the entity version to null in the data source B?

> We need to copy data from one data source to another, and need keep same id to keep entity relations.
> 1. fetch entities from data source A
> 2. evict entities from session, set version to null, keep id not changed.
> 3. create entities in data source B.
> for @GeneratedValue(strategy = GenerationType.AUTO), entity id is reset by Hibernate.
> But for auto increment id in mysql, it can be set manually and AUTO_INCREMENT is automatically adjusted.
