    • A data processing system-implemented method, system and article of manufacture for differential schema migration. A differential schema migration system can include a schema extractor configured both to extract a contemporary schema and corresponding contemporary data from a first connected database and also to generate an intermediately formatted form of the contemporary schema and corresponding contemporary data. The system also can include a schema update user interface configured to facilitate applying changes to the intermediately formatted form of the contemporary schema and corresponding contemporary data. Finally, the system can include a schema differential migrator configured to apply changes to a second connected database based upon a comparison of an extracted schema and corresponding data from the second connected database, and a changed version of the intermediately formatted form of the contemporary schema and corresponding contemporary data.
