Converting Unmanaged to Managed devices in iOS 7 OTA iOS 7 introduces the concept of enrolling Apple devices with MDM providers out of the box, so when the iPads are being sent out by Apple to companies, they can be enrolled into an MDM program and the device can be managed through out by the MDM provider right from when the iPad is unboxed, but the documentation is not clear on devices that already are out there.

Is there a way to convert unmanaged unsupervised devices to managed devices? …and I don't mean app level management (i.e I know it is possible to use Configurator to push certain apps that can then be managed, but the rest of the apps cannot).

Is it possible to completely convert an unmanaged device to a managed device such that all the apps, config, settings are controlled by MDM OTA ? The OTA(over the air bit is important too since I am looking to implement it that way).
If all you care about is enrollment - you should be fine. OTA supervision isn't yet being provided according to all the information I've seen as of late October 2013.

There is great confusion out there as Apple did promote the idea that OTA Supervision was coming with iOS 7. That feature was dropped from the public list of features about a week before release and there is no official word if or when it may come back.

There is a difference between iOS supervision and iOS MDM enrollment. The latter item is easy - most all MDM can enroll devices over the air on iOS 6 and that ability continues on iOS 7.

Over the air supervision is not possible on iOS 6 and requires Apple Configurator to supervise devices before you choose to enroll them into MDM.

Over the air supervision is not possible on iOS 7.0.2 and even the 
"streamlined MDM enrollment" that is still listed is either not working or waiting on the MDM providers to update their software to take advantage of those new settings.

I would expect by late November, there would be good indications that we will or will not get OTA Supervision with iOS 7 this fall as well as which MDM providers (if any) work with the "streamlined" enrollment methods.



And a footnote, there are several reports that a bug in iOS 7 upgrade has caused a portion (but even a portion of 7,000 iPads could run into a hundred devices) where supervised iOS 6 devices were removed from supervision as part of the upgrade process to iOS 7. Anyone affected should contact AppleCare for assistance if you don't want to simple re-supervise the devices.
