Hi,
will will change the database mapping for the inheritance mapping from "Table per subclass" to "Table per class hierarchy" to increase the database performance.

Which is the easiest way to migrate my data from the old database schema to the new schema? Is there any tool support?

Thanks for your help
Peter Fouquet

for the datamodel side, there is hbm2ddl.

Hi Dennis,
my problem is the data migration for more than 100 tables with many foreign key relationships to the new database model.

I'm searching for a solution like:
a) read all objects with the old schema
b) detach the objects from the old persistence session or dump the objects in a temporary store
c) store the objects with the new schema

Kind regards for your help
Peter

oh, so the domain model isn't going to change? just hibernate conf and data model? if that is the case, see this stuff ... http://www.hibernate.org/hib_docs/v3/re ... eplicating
