ORA-13712: Cannot perform ADDM analysis on AWR snapshots from previous releases. Snapshot version "string" do not match the database version "string"
Cause: ADDM analysis can only be performed on AWR snapshots taken in the current release.
Action: One can still generate AWR and ASH reports using ?/rdbms/admin/awrrpt and ?/rdbms/admin/ashrpt on these snapshots to analyze the data in them.
