Enrolling existing devices in MDM and ADE

[RGrayTpT]

Hey,

I have devices enrolled in MDM. Trying to utilize ADE, so that I can push updates and create new management profiles. I have about 300 devices that are already in use...how can I push updates using ADE without having to factory reset these devices? My users are all over the country. Thanks.

It is a requirement from Apple that devices are in ADE before this can be used

And the only way to retrospectively add devices in ADE is after they've been reset, and are at the start of the setup assistant.

Sorry to be the bearer of bad news.

It's not possible as already mentioned, ADE connection to an MDM happens when a device is first setup.
