The invention refers to a transfer of a User Equipment, UE, context within a secondary network from a secondary network node (110A) to a new secondary network node (110B), wherein the UE (105) is served by a master network node (120) and the secondary network node (110A), the method comprising: the UE receiving a first message (1202) indicative measurement configuration constructed by the secondary network node (110A); the UE performing, based on the measurement configuration, measurements of potential candidates for anew secondary network node (110B); and the UE sending a second message (1203) comprising a measurement report indicative of the measurements of potential candidates for the new secondary node. The invention further relates to a secondary network node adapted to perform the method steps of initiating sending a first message (1202) indicative of a secondary network node measurement configuration to the UE (105); and receiving a second message (1203) comprising a measurement report indicative of the measurements of potential candidates for a new secondary node from the UE (105).
