VOS Lite and VOS Support

You can install the VOS Lite software on a branch device that is already running the full-featured VOS software. You can also re-install the full-featured VOS software on a device that is running the VOS Lite software using the CLI. All branch devices must be running Ubuntu 18.04 (Bionic) as the base operating system.

The following table describes the software packages for installing the VOS Lite and VOS software.

Before You Begin

Before you install the VOS Lite image on a device running the full-featured VOS software, do the following:

• Download the VOS Lite image file to the Director node. For more information, see Download Controller and VOS Software Image to Director Node.
• If the device configuration includes advanced features that are not supported in the VOS Lite image, you must remove the configuration for those features. The following features are not supported in the VOS Lite image:
  • Application delivery controller (ADC)
  • Data loss prevention (DLP)
  • Kernel crash dump (kdump)
  • Universal CPE (uCPE)

If you have configured any of these advanced features from the CLI, you must remove these commands from the configuration. If you do not remove them, when you commit a VOS Lite configuration, the commit fails and an error message is displayed. The following are some of the commands for configuring advanced features that you must remove from the configuration:

• set orgs org-services tenant-name adc
• set orgs org-services tenant-name security profiles dlp
