Dell ThinOS 10.x Migration Guide

ThinOS 10.x upgrade or downgrade using WMS

ThinOS 10.x (version 2508 and later) supports seamless upgrade and downgrade between ThinOS 10 N and N+1 versions using Wyse Management Suite (WMS). This capability enables remote management, automatic rollback, and configuration alignment without manual intervention.

The following are the key features:

• Remote upgrade or downgrade initiation—IT Administrators can initiate ThinOS 10.x upgrades or downgrades remotely using the Wyse Management Suite (WMS) console, streamlining deployment and minimizing endpoint downtime.
• Add-on package compatibility—During the upgrade or downgrade process, existing add-on packages are either retained or automatically updated to maintain compatibility with the target ThinOS version.
• Automatic configuration updates—WMS automatically updates endpoint configurations to match the upgraded or downgraded ThinOS version, ensuring consistent user experience and system behavior.
• Automatic rollback on failure—If an upgrade or downgrade fails, ThinOS automatically reverts to the last known working version to prevent service disruption and maintain endpoint stability.
• Failure logging and troubleshooting—The IT Administrators can access the detailed endpoint logs to support debugging and troubleshooting, enabling quick resolution of upgrade issues.
• Signing certificate tolerance—ThinOS upgrades and downgrades between N and N+1 versions are not impacted by changes in signing certificates, ensuring a smooth transition.
• Certificate retrieval from WMS—If a signing certificate mismatch occurs, the client fetches the correct certificate from WMS to complete the upgrade successfully.
