Before you proceed with the Sensor software upgrade, you must upgrade the Manager to 6.0. See Upgrading the Manager. For I-series Sensors, the NAC feature is not supported in 6.0. So, an I-series Sensor configured for NAC in 5.1, does not enforce NAC when you upgrade it to 6.0. If you have I-series Sensors configured for NAC, and if you want to upgrade to 6.0, contact McAfee Support.

Difference between an update and an upgrade
A software update is a minor release of device software. A device refers to a Sensor or an NTBA
Appliance as applicable. An upgrade indicates a major release and new feature set. These processes
are identical, and thus this section makes references to update and upgrade in an interchangeable
manner.
Any change to device software—whether update or upgrade—requires you to reboot the device.
