Re: [eclipselink-users] How to compare entities from two different databases and replace one with the other?

You can use dbunit to compare data in tables.   Ant tasks are simple,
but you can do it programmically as well.

You can also use dbunit to export data from one database and import it
into another database, again, either using ant or java code.
