Upgrade ThinOS 8.6 to ThinOS 9.1

Prerequisites

  • Upgrade the thin client to ThinOS 8.6_807 with the latest available BIOS version. For the latest BIOS version, see Introduction. For more information about how to upgrade BIOS on your ThinOS 8.6 client, see the Dell Wyse ThinOS Version 8.6 Administrator’s Guide at www.dell.com/support.
  • The ThinOS conversion image must be added to the ThinOS firmware repository. For more information, see Add ThinOS firmware to the repository.
  • Create a group in Wyse Management Suite with a group token.
  • The thin client must be registered to Wyse Management Suite.

Steps

  1. Go to the Groups & Configs page, and select a group.
  2. From the Edit Policies drop-down menu, click ThinOS.
    The Select ThinOS Configuration Mode window is displayed.
  3. Select Advanced Configuration Mode.
  4. Go to Firmware Upgrade, and click Configure this item.
  5. Clear the Disable Live Upgrade if you want to upgrade immediately and clear the Verify Signature check box as well.
  6. From the Platform Type drop-down list, select the platform.
  7. From the Firmware to auto-deploy drop-down list, select the firmware added to the repository.
  8. Click Save & Publish.
    The firmware is deployed to the thin client. The conversion process takes around 10 minutes, and the thin client restarts automatically. After the upgrade is complete, the device is automatically registered to Wyse Management Suite.
    NOTE The download of the ThinOS 9.1 image from Wyse Management Suite (both private and public cloud) to the thin client takes around nine minutes depending on the network bandwidth or cloud server performance. The device reboots after the ThinOS image has been downloaded. After the upgrade is complete, the device is automatically registered to Wyse Management Suite.
    NOTE You can add the ThinOS policy with ThinOS 8.6 to ThinOS 9.1.1131 base image and ThinOS 9.x policy with ThinOS 9.x operating system image in the same group. This enables you to upgrade from ThinOS 8.6 to ThinOS 9.x or later versions directly.
    NOTE If a black screen is displayed after the upgrade, you must perform a hard reboot.
