Firmware upgrade

Use the Wyse Management Suite version 2.0 to upgrade your ThinOS 8.6-based thin clients to ThinOS 9.0. It is recommended to use Wyse Management Suite for large deployments. You can also use the USB Imaging Tool version 3.3 to install the ThinOS 9.0 Merlin image on a single device.

NOTE You cannot upgrade the ThinOS 8.6 clients with PCoIP as ThinOS 9.0 does not support PCoIP devices.

For more information about how to upgrade from ThinOS 8.6 firmware to ThinOS 9.0, see the Dell Wyse ThinOS Version 9.0 Migration Guide at www.dell.com/support.

NOTE After you upgrade to ThinOS 9.0, you cannot use the Wyse Management Suite method to downgrade to ThinOS 8.6. You must use the USB Imaging Tool method with Merlin images to downgrade to ThinOS 8.6.
