1. A method for execution by one or more processing modules of one or more computing devices of a dispersed storage network (DSN), the method comprises: determining that an access metric regarding an encoded data object exceeds an access threshold, wherein the encoded data object is stored as a first plurality of sets of encoded data slices based on first dispersed storage error encoding parameters; and when the access metric exceeds the access threshold: retrieving a first decode threshold number of encoded data slices of each set of the first plurality of sets of encoded data slices; decoding the first decode threshold number of encoded data slices of each set to recover the data object; re-encoding the recovered data object using second dispersed storage error encoding parameters to produce a re-encoded data object, wherein the re-encoded data object includes a second plurality of sets of encoded data slices and wherein a second decode threshold number associated with the second dispersed storage error encoding parameters is less than the first decode threshold number; outputting the second plurality of sets of encoded data slices to storage units of the DSN for storage therein; and sending a message to retrieving devices of the DSN, wherein the message indicates use of the second plurality of sets of encoded data slices for the data object.
