1. A computer readable storage device comprises:

  • a first memory section for storing operational instructions that, when executed by a processing module of a storage unit of a dispersed storage network (DSN), causes the processing module to;

    transition storage of one or more groups of encoded data slices from storage based on a previous version of a distributed agreement protocol to storage based on a new version of the distributed agreement protocol; and

    a second memory section for storing operational instructions that, when executed by the processing module of the storage unit, causes the processing module to;

    while transitioning storage of the one or more groups of encoded data slices;

    receive a proxied data access request regarding an encoded data slice from another storage unit of the DSN;

    determine whether the other storage unit is an authentic storage unit of the DSN based on at least one of;

    the encoded data slice, the previous version of the distributed agreement protocol, and the new version of the distributed agreement protocol;

    when the other storage unit is the authentic storage unit, process the proxied data access request to produce a data access response; and

    send the data access response to the other storage unit.
