Upgrade from ThinOS 8.6 to ThinOS 9.1.5067 using Wyse Management Suite
If you are running any ThinOS 8.6 version, you must first install the ThinOS 8.6_807 image with the latest BIOS version, and then upgrade to ThinOS 9.1.5067. For the latest BIOS versions, see the
Dell Wyse ThinOS Version 8.6_807 Release Notes at

The device reboots after the ThinOS image is downloaded. Once the upgrade completes, the device is automatically registered to Wyse Management Suite. Dell Technologies recommends you to back up your device settings before you initiate the upgrade process. All device settings are erased after you upgrade from ThinOS 8.6 except the following settings:
Wyse Management Suite group token and server settings
Static DNS
Certificates
IEEE802.1x wired authentication settings
Wireless connections—The WEP/Sharekey security type is changed to
Open as they are not supported in ThinOS 9.1
Proxy settings
