The present invention relates to a method for modernizing an elevator group (11). The elevator group (11) in this case comprises a plurality of elevators (13a, 13b, 13c) each having a car (15a, 15b, 15c) and an elevator controller (17a, 17b, 17c) for controlling the respective car (15a, 15b, 15c). As part of the modernization process, at least one input terminal (21) for capturing destination call signals is fitted and a group computer (23) is installed. The group computer (23) is suitable for evaluating the destination call signals and for outputting at least one first control signal. Additionally, for each elevator (13a, 13b, 13c), a control unit (27a, 27b, 27c) for reading in the first control signal and a control module (29a, 29b, 29c) are respectively installed on the respective car (15a, 15b, 15c) for delivering an internal call, triggered by the first control signal, for the respective car (15a, 15b, 15c).
