1. A system migration support apparatus comprising:
a first rule generator configured to generate 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 rule generator configured to generate 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 rule generator configured to identify 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,
wherein the third rule generator configured to generate second correspondence information showing correspondence relationships between the portions of the second data and portions of the third data, and
the migration support apparatus comprises a fourth rule generator configured to generate information showing a correspondence relationship between the migration destination system and the migration source system, based on the second correspondence information and the first correspondence information.
