How to Upgrade Content Analysis.

In the "Release" drop down choose the version that is needed.
There are two ways to upgrade the unit, either by locally uploading the image to the device or downloading it via a URL directly to the unit. See the instructions for both options below.
Both options can be used in the Content Analysis Management Console under System -> Firmware
After successfully uploading the image, verify that the newly downloaded version is the default image, click save changes and click on Reboot system and load saved default system image.
Note: Content Analysis can store up to five unique software images.
