1. A method for execution by a device within a distributed storage and task network, the method comprises: determining whether at least a portion of temporarily stored data is to be stored long-term, wherein the temporarily stored data is stored in a set of distributed storage and task (DST) units in accordance with a computational-orientated dispersed storage error coding function; when the at least a portion of the temporarily stored data is to be stored long-term: identifying one or more DST units of the set of DST units storing the at least a portion of the temporarily stored data in accordance with the computational-orientated dispersed storage error coding function; recovering the at least a portion of the temporarily stored data from the one or more DST units in a pre-dispersed storage error encoded format to produce recovered data; dispersed storage error encoding the recovered data into a plurality of sets of encoded data slices in accordance with a long-term-storage-orientated dispersed storage error coding function; and storing the plurality of sets of encoded data slices in the set of DST units.
