Upgrading IGEL Devices from IGEL OS 10 to IGEL OS 11

This document describes how to upgrade any number of IGEL Universal Desktop devices (UD) from IGEL OS 10 to IGEL OS 11.

IGEL OS 10.05.700 or higher is required for upgrading to IGEL OS 11. If you have an older version of IGEL OS 10, you need to update to version 10.05.700 or a higher version first. 

The following methods of mass deployment are described here:

• Zero-Touch Deployment Using Universal Firmware Update: Mass upgrade from any version of IGEL OS 10 to IGEL OS 11 in one step using Universal Firmware Update. This method can be started immediately or as a scheduled job (wake up or reboot).

• Zero-Touch Deployment Using Buddy Update 1: Mass upgrade from any version of IGEL OS 10 to IGEL OS 11 in one step using two devices as update buddies. This method can be started immediately or as a scheduled job (wake up or reboot).

• Mass Deployment Using a Scheduled Job: Upgrade devices that are already running IGEL OS 10.05.700 (or higher) using a specific scheduled job.
