When moving an agent between Security Servers:
If an agent running an earlier version moves to a Security Server running the current version, the agent will be upgraded automatically.
Do not move an agent running the current version to a Security Server running a previous version because the agent will become unmanaged (the agent will unregister from its previous server but will fail to register to its new server, therefore, it will not appear in either web console). The agent will keep its current version and will not downgrade.
The Security Servers must be of the same language version.
Record the host name and listening port of the Security Server to which an agent will move. The host name and listening port are found on the Security Server’s Security Settings screen, above the Tasks panel.
A new screen appears.
If the Security Agent does not appear in the Security Groups Tree, restart the Trend Micro Security Server Master Service.
