Workspace ONE UEM can replace an internal application on devices but it does not deploy multiple versions to devices. You can have multiple, active versions in the console for management. Replacing a retired version depends on the Actual File Version value.
If you want multiple versions of an application in the Workspace ONE UEM console, do not select the Retire Previous Version check box on the Details tab. This check displays when you add a version of an application.
If you do not select Retire Previous Version, and you add an application version, Workspace ONE UEM assigns the higher Actual File Version to devices.
You can Deactivate application versions rather than retiring them to remove them from device assignments.
