Abstract
A method begins by a processing module monitoring a reprovisioned memory device that has been reprovisioned from a legacy storage protocol to an error coding dispersed storage protocol. The method continues with the processing module determining a data migration scheme for migrating a plurality of encoded data slices stored on the reprovisioned memory device and migrating the plurality of encoded data slices from the reprovisioned memory device to one or more other memory devices in accordance with the data migration scheme when a usable memory life of the reprovisioned memory device in the error coding dispersed storage protocol has expired.
