Abstract: A device transmits operation information to a connected server. A second server transmits, to a first server, a request for first connection information for the device to connect to the first server based on reception of a registration request accompanying a firmware update from the device. The first server, after a reception of the request for the first connection information, starts transferring, to the second server, data related to the device, and transmits to the second server the first connection information in response to the request. The second server transmits to the device the first connection information received from the first server. When the transferring of the data related to the device reaches a predetermined step, second connection information for connecting to the second server is transmitted from either the first server or the second server to the device.
