Abstract: A method and apparatus for use in managing transport migration for traffic related to an Integrated Access Backhaul, IAB, node, is disclosed. The transport migration to be performed after a Distributed Unit, DU, of the IAB-node has been migrated from a source IAB topology managed by a source IAB-donor Central Unit, CU, to a target IAB topology managed by a target IAB-donor-CU. A method at the target IAB-donor-CU comprises: receiving a notification including identification information for identifying an IAB-donor-CU serving a Mobile Termination, MT, of the IAB-node, the IAB-donor-CU serving the MT of the IAB-node being a different IAB- donor-CU to the target IAB-donor-CU; based on the identification information and after the DU of the IAB-node has been migrated to the target IAB topology, performing transport migration for migrating traffic related to the IAB-node for routing over at least one path between the target IAB-donor-CU and the IAB-node through an IAB topology managed by the IAB-donor-CU serving the MT. The target IAB- donor-CU may receive the notification from the source IAB-donor-CU, from the IAB-node or from the IAB-donor-CU serving the MT.
