1. A network node for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
transmit, to a user equipment (UE), a radio resource control communication that includes one or more indications corresponding, respectively, to one or more target primary cells, each indication indicating whether the UE is to keep or discard a conditional handover configuration associated with a respective target primary cell upon completing a primary cell addition procedure;
receive, from a source master node, a secondary node release request corresponding to a conditional handover operation associated with the UE operating in accordance with multiple radio access technology dual connectivity, wherein the secondary node release request indicates that the network node is to continue to be a secondary node associated with the UE or that a target secondary node is to be the secondary node associated with the UE; and
perform a data transfer operation based at least in part on receiving the secondary node release request.
