1. A method for wireless communication at a user equipment (UE), comprising:
determining to perform a handover from a first source device in a first network to a first target device in the first network and from a second source device in a second network to a second target device in the second network, wherein the first source device in the first network and the second source device in the second network are in a first dual connectivity configuration and the first target device in the first network and the second target device in the second network are in a second dual connectivity configuration;
identifying a time interval for performing a first random access procedure with the first target device in the first network;
initiating the first random access procedure with the first target device in the first network;
performing a second random access procedure successfully with the second target device in the second network during the time interval; and
transmitting to or receiving from the second target device in the second network data after performing the second random access procedure successfully and before the UE finishes performing the first random access procedure with the first target device in the first network.
