1. A method comprises: detecting, by storage units of a first pool of storage units of a plurality of pools of storage units, a change to a weighting factor of a second pool of storage units of the plurality of pools of storage units; calculating, by each of the storage units of the first pool of storage units, an updated plurality of storage pool scores for the plurality of pools of storage units for a respective encoded data slice of a set of encoded data slices that is currently stored by a respective storage unit of the first pool of storage units, wherein an updated storage pool score of the second pool of storage units is based on a changed weighting factor of the second pool of storage units, wherein the updated plurality of storage pool scores for the plurality of pools of storage units are based on a decentralized agreement protocol function; identifying, by each of the storage units of the first pool of storage units, one pool of storage units of the plurality of pools of storage units having a desired storage pool score based on the updated plurality of storage pool scores for the plurality of pools of storage units that are based on the decentralized agreement protocol function, wherein the first pool and the second pool of storage units of the plurality of pools of storage units are implemented within a dispersed storage network (DSN), and the one pool of storage units is identified from among the plurality of pools of storage units; and when the one pool of storage units is not the first pool of storage units, transferring, by each of the storage units of the first pool of storage units, the respective encoded data slice to a corresponding storage unit of the one pool of storage units, wherein a first respective encoded data slice of the set of encoded data slices that is stored in a first storage unit of the first pool of storage units is transferred via the DSN to a first storage unit of the one pool of storage units to be stored therein, and a second respective encoded data slice of the set of encoded data slices that is stored in a second storage unit of the first pool of storage units is transferred via the DSN to a second storage unit of the one pool of storage units to be stored therein.
