A method for renovating an existing elevator includes connecting a new group supervising apparatus that is connected to new landing operating panels to an existing elevator controlling apparatuses by a relaying apparatus that includes a relay panel and an input/output panel to enable existing elevator cars to be operated by the new group supervising apparatus. The existing group supervising apparatus is removed with the landing operating panels. New elevator cars and new elevator controlling apparatuses are substituted for the existing elevator controlling apparatuses together with the existing elevator cars. The new elevator controlling apparatuses are connected to the relaying apparatus to enable the new elevator cars to be operated by the new group supervising apparatus. The renovating method enables substitution of a new system of group supervised elevators without losing overall elevator service during a refurbishment transition period, and enables an elevator to be refurbished without losing elevator operating efficiency.
