Abstract

See full text

Based on a system configuration change (e.g., of a Decentralized, or Distributed, Agreement Protocol (DAP)) within a dispersed storage network (DSN) (e.g., from a first to a second system configuration of the DAP), a computing device directs a storage unit to be replaced (SUTBR) to transfer encoded data slices (EDSs) stored therein to a replacement storage unit (RSU). During transfer of the EDSs (e.g., from SUTBR to RSU), the computing device directs the SUTBR to service read and/or write requests for EDS(s) stored therein to operate based on a first system configuration of the DAP. When the EDSs have been successfully transferred from the SUTBR to the RSU, the computing device directs the RSU to service read and/or write requests for the EDS(s) stored therein to operate based on a second system configuration of the DAP.
