Upgrading Agent Software
It is recommended to upgrade the agent using the same method as deployment.
Software Management System or Group Policy
Download the agent package from FortiNAC. For instructions, see section Download the Persistent Agent for custom distribution in the appropriate Administration Guide:
When using Group Policies, add the new agent package and list it as an upgrade to the previous versions. Ensure any previous package referenced by the GPO remains in place until all hosts have successfully moved off that version. For assistance, consult vendor documentation.
FortiNAC Captive Portal
For Persistent Agents distributed via the Captive Portal, see section Upgrade the Persistent Agent of the appropriate Administration Guide for agent upgrade instructions.
