1. A method comprises:

  • determining, by a computing device, an encoding modification for a set of encoded data slices, wherein a data segment of data is dispersed storage error encoded into the set of encoded data slices based on dispersed storage error encoding parameters;

    determining, by the computing device, a plurality of tasks for executing the encoding modification, wherein the encoding modification includes altering one or more parameters of the dispersed storage error encoding parameters;

    dividing, by the computing device, a first task of the plurality of tasks into one or more partial tasks based on the first task;

    assigning, by the computing device, a first partial task of the one or more partial tasks to a first storage unit;

    dividing, by the computing device, a second task of the plurality of tasks into a plurality of partial tasks based on the second task;

    assigning, by the computing device, the plurality of partial tasks to a set of storage units; and

    executing, by the first storage unit and at least some storage units of the set of storage units, the first partial task and the plurality of partial tasks, respectively, to produce a modified set of encoded data slices.
