Think about data migration features
-----------------------------------

                 Key: OGM-82
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/OGM-82
             Project: Hibernate OGM
          Issue Type: New Feature
            Reporter: Emmanuel Bernard


You can migrate data in two ways:
* batch change
* on the fly upon reading the value

The idea is to provide annotations, metadata or callback to migrate data on the fly while OGM loads tuples. Objectify has this concept http://code.google.com/p/objectify-appengine/wiki/IntroductionToObjectify#Migrating_Schemas

Morphia too (@AfterLoad)

Thanks for Scott Hernandez for pointing that out.
