Use the following workflow to upgrade the WF-500 appliance operating system. The appliance can only use one environment at a time to analyze samples, so after upgrading the appliance, review the list of available VM images and then choose the image that best fits your environment. In the case of Windows 7, if your environment has a mix of Windows 7 32-bit and Windows 7 64-bit systems, it is recommended that you choose the Windows 7 64-bit image, so WildFire will analyze both 32-bit and 64-bit PE files. Although you configure the appliance to use one virtual machine image configuration, the appliance uses multiple instances of the image to perform file analyses.
