• The working primary should show, as in the example below, in /opt/rsa/am/replication/r2p_chgsets_to_apply/.  Note the changeset value then look for that specific value, as shown.

• The cause is unknown as of the writing of this article.

1. Delete the problematic replica instance and apply RSA Authentication Manager 8.2 to the primary instance.
2. In the primary's Operations Console select Deployment Configuration > Instances > Status Report.
3. From the replica context menu, select Delete.  This will enable to apply the RSA Authentication Manager 8.2 upgrade successfully.  Note:  Stopping all the replica services does not correct the issue.  It is required to explicitly delete the replica to clear the relevant tables in the database.
4. Redeploy the problem instance.
