Upgrade to Oracle Database 23ai by Creating a Full Clone
If your Autonomous Database instance is using Oracle Database 19c you can upgrade to Oracle Database 23ai by creating a full clone.
To upgrade your Autonomous Database by creating a full clone, do the following:
See Clone an Autonomous Database Instance for the detailed steps for this type of clone.

The clone has its own wallet and you cannot use the wallet of the source database to connect to the clone. All users must obtain a new wallet and use the new wallet to access the upgraded database. See Download Client Credentials (Wallets) for more information.
