Migrate database components after you install the new products and prepare the old installations.

Use the same type of RDBMS in the new environment that you used in the old environment. The use of a different RDBMS in the new environment is not supported, therefore, cross RDBMS migrations are also not supported.

The new release might require changes to the database components, such as new tables, columns, keys, or indexes. In Migrate Database Components Using Database Component Configurator, you run database migration scripts that update the existing database schemas so they are compatible with the new product release. The scripts might modify the existing database components, or might create parallel database components with the new structure and then insert, select, rename, and drop the tables, columns, keys, and indexes. These changes might increase the size of your database.
