The Upgrade Policy section of the Create Group or Edit Group panel lets you set a policy to upgrade installed sensors in the sensor group.
Upgrade policy options are as follows:
No automatic updates – Manually decide when to upgrade sensors.
Automatically install the latest version – Automatically upgrades the sensors to the latest version.
Automatically install a specific version – Installs a specific version for all sensors in a group. This maintains all sensors at the selected version. Select a version number using the drop-down list. Selecting the upgrade policy of a specific version is useful when sensor versions must be tested.
