Embodiments include methods performed by a centralized unit, CU, in a radio access network (RAN) that includes a first node. Embodiments include determining that a control plane (CP) connection between the CU and the first node should be moved from a source path in the RAN to a target path, which includes at least one radio access node not in the source path. Embodiments also include, based on determining that the CP connection should be moved, sending to the first node a message including transport network layer (TNL) association(s) related to the CP connection. The message is sent before the first node relocates to the target path. Embodiments also include, after the first node has relocated to the target path, establishing a transport layer protocol connection with the first node over the target path based on the TNL association(s).
