1. A method of wireless communication performed by a master node (MN), comprising:
receiving information indicating a target secondary node (SN) for an inter-system handover of a user equipment (UE) from a New Radio (NR) standalone mode to an E-UTRA-NR dual connectivity (EN-DC) mode, wherein the information indicates that the target SN is associated with a direct forwarding path between the target SN and a source radio access network (RAN) node of the UE; and
performing the inter-system handover of the UE from the source RAN node to the MN and the target SN, wherein the target SN is different than the source RAN node of the UE.
