On removing the DEP Server from the ZENworks Management Zone, the DEP Profile from the associated devices are automatically unassigned. The Discovered devices are removed from the zone but the Managed devices will continue to be managed by the ZENworks MDM Server.
To remove the DEP Server from your ZENworks Management Zone:
Navigate to Configuration > Management Zone Settings > Discovery and Deployment > Apple Device Enrollment Program.
Select a DEP Server and click Remove. You can remove only one DEP Server at a time.
NOTE:Before removing the DEP Server in ZCC, if you delete the virtual MDM Server in the Apple portal, then the associated DEP Server is not automatically deleted by ZENworks. As a best practice, we recommend that you remove the DEP Server in ZCC and then proceed to remove the virtual MDM Server.
