A system migration support apparatus enhances reproducibility of operation of a migration source system in a migration destination system, by including a first generation unit generating first data showing information about operation of a migration source system in a form dependent on an implementation technique of the migration source system, based on materials of the migration source system; a second generation unit generating second data showing the information about the operation in a form independent of a particular implementation technique, based on the first data, and generating first correspondence information showing correspondence relationships between portions of the first data and portions of the second data; and a third generation unit identifying the portions of the first data corresponding to the portions of the second data, referring to the first correspondence information, and generating third data showing the information about the operation in a form dependent on an implementation technique of a migration destination system, based on the identified portions.

System migration support apparatus, system migration support method and program to enhance reproducibility of migration destination system

A conversion apparatus improves utilization of definition information for system migration by including: a first conversion unit converting definition information about first rules for generating first data showing information about an operation of a migration source first system in a form depending on an implementation technique of the first system based on materials of the first system, according to a combination of first environment information showing an environment that the first system depends on and second environment information showing an environment that a migration destination second system depends on; a second conversion unit converting definition information about second rules for generating second data showing the information about the operation in a form not depending on a particular implementation technique based on the first data, according to the combination of the first environment information and the second environment information; and a third conversion unit converting definition information about third rules for generating third data showing the information about the operation in a form depending on an implementation technique of the second system based on the second data and the first data, according to the combination of the first environment information and the second environment information.
