Managing Duplicate Devices

This section is applicable to Android, iOS, macOS, and Windows 8 devices.

By selecting Enable managing duplicate devices, administrators can set duplicate active devices to the Retire or Wipe status or to the Unknown status. Administrators can also set a scan schedule for either Daily, Weekly or Monthly.

Removal of device records from the Ivanti EPMM database applies to the following retired device types:

Android Enterprise devices - When a new Android device is registered, Ivanti EPMM matches its device attributes (MAC, Serial Number, etc.) and its registration status (mode) to any existing entries. If the latest entry is found to duplicate the previous (old) entry, the old entry deleted and an error is entered into the logs.
Active Devices with no device details (iOS and Windows 8 devices)
Devices with no subject holder (iOS and Windows 8 devices)
Devices with the below statuses (iOS Only)
- Enrollment Verified
- Enrolling
- Enrolled

Ivanti EPMM matches devices by device type. Ivanti EPMM uses various device information to determine whether a device is a duplicate or not. For information on finding devices by device type for Apple User Enrollment, see Apple documentation.
