Dell Wyse ThinOS 9.1.4234, 9.1.5067 and 9.1.6108 Migration Guide

Important notes

• All device settings are erased after you upgrade from ThinOS 8.6 to 9.1.4234 or later versions 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 9.1.4234 or later versions.
  • Proxy settings
• If you are an English-language user, do not modify any language settings in Wyse Management Suite. The default language is English after you upgrade from ThinOS 8.6.
• If you are a multilanguage user, ThinOS 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 interface.
• You cannot boot into ThinOS 9.1.4234 or later versions when you perform the following operations:
  • Disable the onboard Network Interface Card (NIC), Trusted Platform Module (TPM), or Platform Trust Technology (PTT).
  • Clear TPM or PTT.
  • Reset BIOS to factory default settings.
• If the thin client is registered in Wyse Management Suite group 1 and you set Wyse Management Suite group 2 token in group 1 policy, the group 2 token is applied on UI but the thin client remains in group 1. You must reboot the thin client to change the thin client to Wyse Management Suite group 2.
  NOTE: Dell Technologies recommends that you set a new ThinOS application package or ThinOS firmware package in group 1, so that thin client installs the package and automatically reboot and changes to group 2.
  NOTE: If you are using ThinOS 9.1.1131 or any previous version, you must set Wyse Management Suite group token and server in group 2 policy, or the connection from the client to Wyse Management Suite is lost.
• ThinOS 9.1.4234 or later versions does not apply operating system firmware application package and BIOS firmware in the child select group.
• When you set a new firmware or an application package in Wyse Management Suite group 2 and then change the device from group 1 to group 2 before upgrading, the following two notifications are displayed:
  • WMS server or group is changed. System is going to reboot to load full configuration. Press cancel in 60 seconds to prevent reboot.
  • A new firmware or application is available, do you want to upgrade now or defer to the next reboot? The changes will automatically be applied in 120 seconds.

  For ThinOS 9.1.5067 and earlier versions, if you do not select an option, the thin client reboots after 60 s. After reboot the new application or firmware is installed and the thin client reboots again.

  For ThinOS 9.1.6108 and later versions, it prompts the new firmware or application available notification first. If you do not select an option, then the thin client installs the new application or firmware and reboots your thin client. If you select Next Reboot, the thin client prompts the WMS server or group change notification.

• If the Live Update option is disabled, the thin client cannot download and install a firmware or package until the next reboot. However, the firmware or packages are downloaded in the following scenarios even when the Live Update option is disabled:
  • When you register the thin client to Wyse Management Suite manually.
  • When you power on the thin client from a power off state.
  • When you change the Wyse Management Suite group.
• When a new firmware or an application notification is displayed on your thin client, clicking Next Reboot will:
  • Display a notification if you have changed the Wyse Management Suite group and if the files are downloaded from the new group.
  • Not display any notification from ThinOS 9.1.6108, if the new firmware or application is downloaded in the same group.
  • Install the firmware or package after a reboot.
• The upgrade may fail if the event log fails to install. In such an event, you may reboot the device and upgrade again.
