Auto Image Replication (A.I.R.) jobs stop working with status code 5626 after an upgrade to NetBackup version 10.4.0.1.

Problem

After upgrading a NetBackup Primary Server to version 10.4.0.1, A.I.R. (Automated Image Replication) jobs started to fail with Status Code 5626
 

Error Message

After you upgrade both the source and the target master server, you must update the trust relationship on both of the servers. After you update the trust relationship, you can make configuration changes related to the trusted master servers.
The trust relationship implementation for remote master servers has been changed for targeted Auto Image Replication (A.I.R.) on version 8.1 and later. After you upgrade both the source and the target master servers from a pre-8.1 version to a version that is 8.1 or later, you must update the trust relationship between both of the master servers. If you do not update the trust, you cannot create or modify any storage lifecycle policies on the source master server.
 

Cause

After an upgrade, the certificates used in the trust between primary servers for A.I.R. operations may require updating to refresh them.
 

Solution

Run the nbseccmd command to update the certificates used between the primary servers in the A.I.R. configuration.
