By removing the alternative web server β21 and the alternative database β22 from the building Y, the system β on the transfer source network can be used as it is at the transfer destination with almost no influence on the function of the system α.

  Further, in the alternative firewall operation process of H shown in FIG. 1, the alternative firewall 3b is installed and operated in the building Y, and the router 2a, the firewall 3a, the DMZ switching hub 10a, and the private switching 11a from the building X are installed in the building Y. Are switched to the alternative router 2b, the alternative firewall 3b, the alternative DMZ switching hub 10b, and the alternative private switching hub 11b, and the router crossover line 31 and the hub crossover lines 32 and 32 are removed, thereby constituting the network As a result of the relocation, it is possible to prevent the services of the system α and the system β from being stopped for a long time, and the services of the system α and the system β can be stably continued in the relocation destination building Y. Thus, even if the system α and the system β sharing the network are transferred, the functions of the system α and the system β can be used as they are, and the servers of the system α and the system β are rebuilt in the transfer destination building Y. Therefore, the system α and the system β sharing the network provided in the remote monitoring center apparatus can be easily and quickly transferred, and the time required for the transfer work of the system α and the system β can be shortened.

  Further, in the present embodiment, in the router relocation process performed at B1 shown in FIG. 1, the firewall relocation process performed at I1 shown in FIG. By replacing the alternative firewall 3b, the alternative DMZ switching hub 10b, and the alternative private switching hub 11b with the router 2a, the firewall 3a, the DMZ switching hub 10a, and the private switching hub 11a of the transfer source building X, respectively. Since the network used in the building Y can be reconfigured with the equipment used in the relocation source building X, it is possible to reduce the influence on compatibility with each equipment and communication performance.

  Further, in the present embodiment, the alternative web server α21, the alternative database α22, the alternative web server β21, and the alternative database β22 are each configured by a testing machine on which an operation check has been performed in advance, and is shown in FIG. Since the alternative web server α21, the alternative database α22, the alternative web server β21, and the alternative database β22 are operated in D2 and F2 shown in FIG. 1, it is not necessary to check the operation of these devices in the building Y. In the relocation work of the system α and the system β sharing the system α, the time required for setting and confirming the operation of the system α and the system β can be shortened. As a result, the relocation work of the system α and the system β can be performed more quickly, and the burden on the operator can be reduced.

  In addition, although this embodiment mentioned above demonstrated the case where several systems of a remote monitoring center apparatus consisted of two system (alpha) and system (beta), it is not restricted to this case and sufficient communication bandwidth of the network to share can be ensured. If the available IP address is within the upper limit of the network address, it may be composed of three or more systems. Also in this case, as described above by sequentially transferring each system from the building X to the building Y in the same manner as in the above-described alternative system operating machine connection process and system operating machine transfer process of C to F shown in FIG. Similar effects can be obtained.

  Moreover, although this embodiment demonstrated the case where the building X and the building Y adjoin, if the router connecting line 31 and the hub connecting lines 32 and 33 are comprised from the exclusive line, the building X and the building Y will mutually mutually You may be away.
