Symptoms
If you try to delete an interface that was used in an IMT Session (Inbound Migration Tool) it cannot get deleted.

Cannot complete the operation because the resource is under import. (Error Code:0x900012a)
Cause
The Interface can not get deleted because it is used in the interconnect that is automatically created to the remote system used at the IMT.
