You can use the dbupgrad utility to upgrade a version 10 or later database by adding and modifying system tables, system procedures, and database options to enable version 16 features.
The database user specified in the connection-string must have the ALTER DATABASE system privilege, and must be the only connection to the database.
Follow the standard precautions for upgrading software. See Upgrade and rebuild precautions.
Ensure that you have exclusive access to the database to be upgraded and ensure that the version 16 utilities are ahead of other utilities in your system path. See How to ensure that you are running the correct version of the utilities when you have multiple versions installed.
Back up your database files before upgrading. If you apply the upgrade to the existing files, then these files become unusable if the upgrade fails. For information about backing up your database, see Backup and data recovery.
Run the Upgrade utility (dbupgrad) against the database:
dbupgrad -c "connection-string"
For more information, see Upgrade utility (dbupgrad).
Shut down the database and archive the transaction log before using the upgraded database.
