G How the Unified Auditing Migration Affects Individual Audit Features

If you have not migrated your database to use unified auditing, then you can use most of the pre-Oracle Database 12c Release 1 (12.1) auditing features.

Table G-1 describes how the pre-Oracle Database 12c audit features change in the migration.

^Footnote 1These data dictionary views will continue to show audit data from audit records that are still in the SYS.AUD$ and SYS.FGA_LOG$ system tables. Unified audit trail records are shown only in the unified audit trail-specific views. You must be granted the AUDIT_ADMIN or AUDIT_VIEWER role to query any views that are not prefaced with USER_.
