Dell Wyse ThinOS Version 9.0 Migration Guide



This guide contains instructions to migrate from ThinOS 8.6 to ThinOS 9.0 using Wyse Management Suite 2.0.

The overall migration process includes the following tasks:
  1. Register the thin client to the Wyse Management Suite server using any of the following methods:
  2. Optionally, add a ThinOS 8.6-based device to a policy group in Wyse Management Suite to retain the INI file configurations—see Relationship between INI file based and Wyse Management Suite group based configuration.
  3. Download the ThinOS 9.0 firmware from the Dell support site—see Download the ThinOS firmware.
  4. Upgrade the ThinOS 8.6 firmware to ThinOS 9.0—see Upgrade ThinOS 8.6 to ThinOS 9.0.
  5. Configure the ThinOS 9.0-based device using Wyse Management Suite version 2.0—see Configuring a new ThinOS 9.0 client using Wyse Management Suite 2.0.
NOTE: After you upgrade to ThinOS 9.0, you can only downgrade to ThinOS 8.6 by using the USB Imaging Tool and Merlin Images posted on the Dell support site at

English-language user—You do not need to modify any language settings in Wyse Management Suite. The default language is English after you upgrade from ThinOS 8.6.

Multilanguage user—ThinOS 9.0 supports nine languages—English, German, French, Italian, Spanish, Japanese, Chinese Traditional, Chinese Simplified, and Korean. Users of all regions must use the English language firmware image. There is no separate firmware image for Japanese language. The firmware image includes the font and language packages for all the nine languages. You do not need a separate font and language package. You must set the region language in Wyse Management Suite before upgrade from ThinOS 8.6. After the device upgrade process is complete and checked in to the Wyse Management Suite server, the user interface language is changed to the language that you have configured in Wyse Management Suite. You can change the language from either Wyse Management Suite or ThinOS 9.0 interface.
