Improved Role and Privilege Handling During Migration

On Autonomous AI Database on Dedicated Exadata Infrastructure, unsupported role and privilege statements are handled automatically during migration: statements that cannot be applied are ignored, and certain roles are mapped to supported equivalents, such as DBA to PDB_DBA. YOu can review the original and converted statements and the action taken in the DBA_CONVERTED_STATEMENTS view and use the DBMS_CLOUD_ADMIN.PURGE_CONVERTED_STMTS procedure to purge all conversion records or records older than a specified retention date.

See Manage Roles and Privileges when Migrating to Autonomous AI Database, PURGE_CONVERTED_STMTS View and PURGE_CONVERTED_STMTS Procedurefor details.
