First, it is necessary to identify the version to which you want to update.
For the AFW version, access the policy of the devices that need the update and, in the first tab ("Policies"), check the option "Force Urmobo update". Then, click "Save". This way, the devices will receive the update immediately and cannot be used until the update is completed.
For other versions: navigate to the menu "Applications > Update Urmobo" and send the latest version by completing the three steps of the process (Device Selection, Item Selection, and Confirmation).
