Claim Text:
1. A computer system, which migrates an application program execution environment from a first computer to a second computer, wherein the second computer is configured as a virtual computer, which is disposed on a virtual platform for providing a virtual computer, the computer system comprising: a storage control apparatus for storing prescribed data related to the application program; and a management computer, which is communicably coupled to the storage control apparatus, the first computer, and the second computer, and manages the storage control apparatus, the first computer, and the second computer, wherein the management computer executes: a volume preparation process for preparing, in the storage control apparatus, a prescribed logical volume for storing the prescribed data so as to make it possible for the second computer to use the prescribed data related to the application program; a coupling process for communicably coupling a communication interface part of the virtual platform to a communication port part, which is in the storage control apparatus and corresponds to the prescribed logical volume, so as to make it possible to access the prescribed logical volume prepared in the storage control apparatus via the virtual platform; and an allocation process for transparently allocating the prescribed logical volume to the second computer; wherein the management computer executes a specification process prior to the volume preparation process, wherein, in the specification process, in a case where the application program execution environment of the first computer is to be copied to the second computer, information related to a logical volume used by the first computer is acquired from the first computer and presented to a user as copy-source volume candidate information, communication interface identification information for identifying the communication interface part capable of being used by the second computer is acquired from the second computer, a determination is made as to whether there is a communication port part corresponding to the communication interface identification information by querying the storage control apparatus by showing the communication interface identification information, in a case where it has been determined that the communication port part corresponding to the communication interface identification information exists, a list of logical volumes associated with the communication port part is acquired from the storage control apparatus, and presented to the user as copy-destination volume candidate information, a determination is made as to whether a copy-destination volume selected by the user from among the copy-destination candidate information is usable by querying the storage control apparatus by showing information for identifying the selected copy-destination volume, and in a case where it has been determined that the copy-destination volume is usable, information for identifying the prescribed logical volume selected by the user from among the copy-source volume information and information for identifying the copy-destination volume which has been determined to be usable are associated with each other and transferred to the volume preparation process.
