One such method includes: initiating a first instance of a DU of a RAN on a first portion of a plurality of core processors in the cellular network; initiating a second instance of the DU of the RAN on a second portion of the plurality of core processors in the cellular network, wherein the first portion of the plurality of core processors is distinct from the second portion of the plurality of core processors; running the first instance of the DU of the RAN concurrently with the second instance of the DU of the RAN in the cellular network; and swapping the active instance from the first instance of the DU of the RAN with the second instance of the DU of the RAN. ## Claims ### Claim 1 A method for implementing parallel software instances in Open Radio Access Network (O-RAN) with disaggregated hardware and software in a cellular network, the method comprising: providing, by a mobile network operator, a distributed unit (DU) of a cellular telecommunication network radio access network (RAN) that is served by a cellular site base station, wherein the DU is in operable communication with a corresponding primary central unit control plane (CU-CP) of a primary centralized unit (CU) that is hosted on a cloud-native virtualized compute instance;
