A method begins by a dispersed storage (DS) processing module identifying a candidate dispersed storage (DS) unit of a dispersed storage network (DSN). In response to a data migration request, the method continues with the DS processing module receiving a migration receptiveness message from the candidate DS unit. In response to a data migration reference message, the method continues with the DS processing module receiving, from another DS unit of a set of DS units, a migration reference response that includes an indication of storage utilized by the other DS unit. The method continues with the DS processing module determining a storage utilization of the candidate DS unit based on the migration reference response and when the determined storage utilization compares favorably to the reported storage utilization, enabling transfer of data from a DS unit of another set of DS units to the candidate DS unit.
