Upgrading a database adds and modifies system tables, system procedures, and database options to enable version 11 features. It does not change the file format used to store and access data on disk, and so does not give access to all new features and performance enhancements in the latest version of the software.

For information about upgrading the database file format, see Rebuilding version 10 and later databases.

The Upgrade Database Wizard does not upgrade a version 9.0.2 or earlier database to version 11. To upgrade an existing database to version 11, you must unload and reload the database using dbunload or the Unload Database Wizard. See Upgrading version 9 and earlier databases.
