A non-transitory computer-readable storage medium may include instructions stored thereon that. When executed by at least one processor, the instructions may be configured to cause a computing system to at least determine which links connecting old super blocks to old spine blocks via a plurality of Optical Circuit Switches (OCSs) in a network to disconnect to accommodate at least one new super block and at least one new spine block being added to a switching network, the determining including determining a maximum of m links per OCS to disconnect, connect the old super blocks to the at least one new spine block via the OCSs associated with the links to be disconnected, and connect the at least one new super block to the old spine blocks via the OCSs associated with the links to be disconnected.
