Description (partial)

Symptom:
Migration tool is limited in a way, that it migrates subinterfaces automatically for all subinterfaces in the source ASA:
"You do not need to map subinterfaces. The Migration Tool creates subinterfaces on the Firepower Threat Defense device for all subinterfaces in the source ASA configuration."

This approach doesn't take multiple context into account, where a user context might contain only subinterfaces (their definition and relation to physical interfaces is contained in system context). This results with inability to properly map interfaces.

Conditions:
Migration of context, which contains subinterface and not containing parent interface.
