1. In the UMS, select all devices that are to be upgraded and reboot them.

    Alternatively, you can create a scheduled job for reboot or wake up and assign it to the devices or the directory containing these devices; for more information, see Jobs.

    On reboot or wake up, the devices choose the IGEL OS 10 buddy. They ignore the IGEL OS 11 buddy at this stage because this version is not known to them yet. The devices update to the appropriate IGEL OS 10 version (10.05.800 or higher). With this version, the Upgrade to OS 11 parameter is recognized by the devices; also, the devices request IGEL OS 11 licenses from the UMS (Workspace Edition and, if required, Enterprise Management Pack). 
    If no IGEL OS 11 licenses have been deployed on the devices yet, the licenses are deployed within a few minutes. The upgrade will be started when the licenses are deployed. The maximum time period the device will wait for a license is configured by the parameter Timeout waiting for OS 11 license to start automatic upgrade; for details, see Adjusting the Setup.
    The parameters Automatic update check on boot and Automatic buddy detection cause the devices to look for a new firmware and wait for an IGEL OS 11 update buddy to reply. When an IGEL OS 11 update buddy is found, the devices start the upgrade process.

  2. When all devices have been upgraded successfully, remove the "Firmware upgrade to IGEL OS 11" profile.

The upgrade is completed.
