Can i install WDA to Wyse 7020 WES7?

There are two ways that I can think of:

• Download latest WES7 base image from Dell Support. The latest image (7092) includes WDA 14.3 and can configured to register to WMS. This is the recommended option. https://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverid=66x8n&oscode=w74s&productcode=wyse-5010tc-series
• If you have access to the WMS Import Tool (available with subscription to WMS Pro, but the WES Migration Utility works even without it), you can manually execute the WESMigrationUtil.exe using the following command on each client:

WESMigrationUtil.exe [WDA_Agent_Installer] [WMS_Server_and_Port]

For example: WESMigrationUtil.exe WDA_14.4.0.135_Unified.exe https://wmsserver.wms.com:443

Please note that this would register your client within the unmanaged section (quarantine) first and then you can move it to a desired group. If you are unable to get a copy of the import tool, sign up for a free trial of WMS Cloud Subscription and download from WMS Cloud Site (do not import keys to On-premise server as it will lock it forever as a Pro server).
