While trying to remove the existing DEP config from the XMS sevrer console it stays on pending state:

    The connectivity is fine between the XMS server and the DEP portal, by this time we have already removed the another MDM configuration from the DEP portal as its not been used.
    It does not allow us to add the same DEP configuration, from the add option, as the configuration already exist. Gives an error:
Unexpected error at com.citrix.ios.bulkenrollment.handlers.impl.DepAccountHandlerImpl.createOrUpdate from createOrUpdate: could not execute statement
org.hibernate.exception.ConstraintViolationException: could not execute statement
 

1. While the DEP status is set to pending removal on XMS, we have added a new MDM config in the Apple DEP portal.
2. Moved all the devices associated with the new config
3. Once it’s done, remove the original config from the Apple DEP portal
4. Restarted the XMS Server

1. Check the un-enrolled DEP devices on CEM console under "Manage" section.
2. The un-enrolled DEP devices should be displayed with grayed out "MDM" & "MAM" label, delete those devices and then restart server.
3. The DEP account should be deleted automatically.
