PROBLEM TO BE SOLVED: To quickly change a system configuration to an optimum one for providing service, by managing network resources and computer resources in an integrated manner.SOLUTION: A computer system comprising a management computer and a plurality of computers connected through a network provides service using virtual computer resources. The management computer detects a trigger of changing a configuration of the computer system; searches, in the case of needing execution of changeover processing, for a new communication path differing from a communication path being used at present; searches, in the case of needing execution of migration processing, for a new computer for managing a virtual computer resource of a target of the migration processing and searches for a migration path that is a communication path for connecting the new computer with a computer managing, at present, the virtual computer resource of the target of the migration processing; judges whether or not the changeover processing is to affect the migration processing; and determines execution order of the changeover processing and the migration processing on the basis of a result of the judgement. |
