Important:
After you migrate database components to the new release, you can no longer use them with your old environment.

Important:
The new release might require changes to the database components, such as new tables, columns, keys, or indexes. In this section, 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.
