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.
Upgrade the WF-500 Appliance to PAN-OS 7.1
Download the 7.1 software version to the WF-500 appliance. You cannot skip any major release versions when upgrading the WF-500 appliance. For example, if you want to upgrade from PAN-OS 6.1 to PAN-OS 7.1, you must first install PAN-OS 7.0. The WF-500 appliance does not support PAN-OS 7.1.1. However, if you’d like to upgrade connected firewalls to PAN-OS 7.1.1, you can continue to do so after upgrading the WF-500 appliance to PAN-OS 7.1.0. Log in to the WF-500 appliance and download the 7.1.0 software version: admin@WF-500> request system software download version 7.1.0 To check the status of the download, use the following command: admin@WF-500> show jobs all
Install the 7.1 software version on the WF-500 appliance. Install the WF-500 appliance operating system image (downloaded in Step 1) by running the following command: admin@WF-500> request system software install version 7.1.0
Confirm that the installation was successful. Confirm that the upgrade is complete.
