About agent registration after an upgrade

ITMS Installation and Upgrade

The agent registration feature requires a client computer to be allowed to communicate with Notification Server before this Notification Server can manage the client computer. The agent registration feature works only for the agents that are upgraded to the 7.5 version.

See About agent registration

After you upgrade your Notification Server to version 7.5, the Legacy Agent Communication (LAC) mode controls if the computers that use older versions of Symantec Management Agent can communicate with the upgraded Notification Server. If LAC mode is turned on, the legacy agents can communicate with Notification Server and upgrade. Note that if you upgrade from 7.1 SP2 or earlier 7.1 versions, LAC mode is turned on by default.

After Symantec Management Agent is upgraded on your client computers, each upgraded agent sends a registration request to Notification Server to establish communication.

You can check and manage the registration requests in the Symantec Management Console, on the Agent Registration Status page, under Reports > Notification Server Management > Registration.

In addition to manually managing the registration requests, you can configure agent registration policies that automatically allow or block the requests. By default, an agent registration policy that allows all incoming requests is enabled on Notification Server. During the upgrade process, Symantec recommends that you use only the default agent registration policy. In this case, the client computers that you are currently managing are automatically allowed to communicate with the upgraded Notification Server. After most of the computers have been approved, you can create more restrictive agent registration policies.

You can create an Agent Registration Policy in the Symantec Management Console, under Settings > Agents/Plug-ins > Symantec Management Agent > Settings > Registration Policies.

After you finish the upgrade process, Symantec recommends turning off LAC mode on Notification Server.

You can manage LAC mode in the Symantec Management Console, on the Notification Server Settings page, under Settings > Notification Server.

For more information, see the topics about creating an agent registration policy, viewing the Agent Registration Status report, and Legacy Agent Communication in the IT Management Suite Administration Guide.
