A technique maintains online access to data stored in a plurality of storage devices during a hardware upgrade in which the plurality of storage devices moves between storage processor enclosures. The technique involves providing, from the plurality of storage devices, online access to the data while each storage device of the plurality of storage devices resides in a first storage processor enclosure. The technique further involves providing, from the plurality of storage devices, online access to the data while the plurality of storage devices is moved from the first storage processor enclosure to a second storage processor enclosure (e.g., transferring each storage devices one by one before triggering a rebuild process). The technique further involves providing, from the plurality of storage devices, online access to the data while each storage device of the plurality of storage devices resides in the second storage processor enclosure.
