Patent ID: 7743148

Claim:
A server migration planning system for planning server migration from m source servers to at least N destination servers in which m is an integer not less than 2 and N is an integer not less than 1, comprising: a memory device in which a first data indicating resource usage of said respective source servers and a second data indicating resource capacity of said respective destination servers are stored; and a processor configured to allocate said respective source servers to any ones of said destination servers based on said first data and said second data, wherein in packing processing, said processor selects said source servers one-by-one in descending order of said resource usage, selects any one of said destination servers, and makes a comparison between a comparison-object usage, which is said resource usage of said selected source server, and a remaining amount of said resource capacity of said selected destination server, wherein in a case where said comparison-object usage is more than said remaining amount, said processor selects another destination server different from said selected destination server and then carries out said comparison again, while in a case where said comparison-object usage is not more than said remaining amount, said processor allocates said selected source server to said selected destination server.
