A server reassignment support system has a storage device, a deallocated state estimation module and an allocation plan generation module. Stored in the storage device are an operation data indicating operation status of a plurality of physical servers and a plurality of virtual servers and a capacity data indicating resource capacity of each of the plurality of physical servers. The deallocated state estimation module refers to the operation data and the capacity data to extract an overloaded server from the plurality of physical servers, load of the overloaded server exceeding a threshold value depending on the resource capacity. Further, the deallocated state estimation module estimates a state in which at least part of virtual servers allocated to the overloaded server is deallocated as a deallocated server among the plurality of virtual servers. The allocation plan generation module generates an allocation plan for the deallocated server based on the estimated state.
