PROBLEM TO BE SOLVED: To construct an environment switchable from a first system including a server and a storage to a second system different from the first system, according to one aspect of the disclosed technique.SOLUTION: A volume is created in a storage 26 of a first system (a first environment 20) and integrated into a group. A mirroring volume is created in a second system (a second environment 40) and integrated into a group. A setting section 12 sets, to the storage 26 of the first environment 20 and the storage 46 of the second environment 40, connection permission information 30 including identification information Sv of a server 22 for which connection to a volume included in a given group of the first environment 20 is permitted. An obtaining section 14 obtains the connection permission information in the second environment 40 to thereby obtain the identification information Sv of the server for which connection to the group in the storage 26 of the first environment 20 is permitted. Further an allocation section 16 allocates the identification information Sv of the server to a server 42 of the second environment 40. With this, the operation environment of the first environment 20 can be switched to the second environment 40.
