A method begins by receiving a request for a move data function regarding a data object, where the data object is stored at a source DSN location in a first bucket of memory of the DSN. The move data function includes a target DSN location within a second bucket of the memory of the DSN. The method continues by determining dispersed storage error encoding parameters of the first and second buckets. When dispersed storage error encoding parameters of the first and second buckets substantially match, the method continues by creating new metadata, regarding the data object being stored at the target DSN location, that includes a logical address to logical address mapping such that the target DSN location points to the source DSN location and the data object is not physically present at a physical address space that corresponds to the target DSN location.
