TRBL - Profile Installation Failed. The new MDM payload does not match the old payload

Symptoms

An error message appears during enrollment: "Profile Installation Failed. The new MDM payload does not match the old payload"

Causes

Occurs during enrollment when another institution's MDM is already installed on the device.
Devices can only be enrolled in a single MDM at any given time.

Resolution

The user will need to un-enroll their device from the other institution's MDM and then reboot their device before they will be able to enroll.

Any assistance required with un-enrolling will need to be directed towards that other institution's support resources.
