1. A computing device comprising:

  • an interface configured to interface and communicate with a dispersed storage network (DSN);

    memory that stores operational instructions; and

    a processing module operably coupled to the interface and to the memory, wherein the processing module, when operable within the computing device based on the operational instructions, is configured to;

    within a dispersed or distributed storage network (DSN) that includes a plurality of storage units (SUs) that distributedly store a set of encoded data slices (EDSs) associated with a data object, during a transition from a first system configuration of a Decentralized, or Distributed, Agreement Protocol (DAP) to a second system configuration of the DAP, direct at least one SU of the plurality of SUs to service a data access request based on at least one EDS of the set of EDSs based on a DAP transition mapping between the first system configuration of the DAP to the second system configuration of the DAP, wherein the data object is segmented into a plurality of data segments, wherein a data segment of the plurality of data segments is dispersed error encoded in accordance with dispersed error encoding parameters to produce the set of EDSs.
