Hello,
The status shown as "Restart Required" are the machines which requires a restart for making changing to SEP client only.
When there is a migration or upgrade taking place, the Symantec Endpoint Protection Manager console shows "Restarted Required" for clients that have not restarted after the upgrade. The deployment status in the Symantec Endpoint Protection Manager console displays the message, "To provide complete protection Symantec Endpoint Protection requires this computer to restart."
The Symantec Endpoint Protection user interface on the client also shows that a restart is needed.
Regards,
