Abstract: A processor can produce a database catalog for a second version of a database management system of the database. The database catalog can store metadata related to definitions of objects or tables included in the second version of the database. A controller can be caused to be established in memory cells being used for the first version of the database. A copy of the database catalog for the second version of the database management system can be stored in the memory cells being used for the first version of the database. The controller, using the copy of the database catalog, can produce the second version of the database management system. The second version of the database management system can be caused to interact with data stored in a storage of the database. The storage can be included in the memory cells being used for the first version of the database.
