Knox Configure is a device configuration utility.
Knox Mobile Enrolment is for fast enrolment into an MDM – such as Knox Manage, Air Watch, Soti, In Tune etc…. Without an MDM Knox Mobile Enrolment does nothing.
From an upload perspective, when a reseller uploads the device is appears in both Knox Configure and Knox Mobile Enrolment, because they are uploading to Knox Cloud services, which is both solutions.
A reseller may say they are uploading to Knox Mobile Enrolment because that is the one they are more familiar with, but it is to both (KC and KME).
