Abstract: A method for utilizing a decentralized agreement protocol for data access operations in a dispersed storage network (DSN) including a legacy storage unit pool and one or more non-legacy storage unit pools. In response to obtaining a DSN address associated with a data access request, a DSN computing device(s) generates ranked scoring information for the legacy storage unit pool and the non-legacy storage unit pool, the ranked scoring information based at least in part on the DSN address, a first location weight associated with the legacy storage unit pool, and a second location weight associated with the non-legacy storage unit pool. In an embodiment, the first location weight decreases over time (e.g., as a generation of legacy storage units is retired). Based on the ranked scoring information, at least one of the legacy storage unit pool or the non-legacy storage unit pool is selected for processing the data access request.
