• Mgmt—Use to manage application instances. These interfaces can be shared by one or more logical devices to access external hosts; logical devices cannot communicate over this interface with other logical devices that share the interface. You can only assign one management interface per logical device. For ASA, FMC in 6.7 and later, and FDM: You can later enable management from a data interface; but you must assign a Management interface to the logical device even if you don't intend to use it after you enable data management.

You can configure a data interface for management.

Hi Marius, 

the Firepower 4000 series like have difference method, and I cannot find the exact documentation on how to change 

[Marvin Rhoads]

The 4000 and 9300 series use Firepower Chassis Manager to allocate and assign management interfaces to the FTD logical devices.

Please refer to Step 5 here:
