Hi all,
  I've used Hibernate with auto create table data on several projects
previously, so the switch to JDO hasn't been a problem.  However, I
have a question regarding application upgrades.  In previous projects,
we sometimes need to run an SQL script after an application has been
updated to populate default values.  We've also changed one to many
relationships to be many to many relationships etc.  Does anyone have
any experience with migrating data in an application upgrade using
JDO?

Thanks,
Todd
