For a software application that uses a first interface, a method is provided to allow the migration of the software application to a second interface instead of the first interface. The software application may, in some situations, be migrated without having to modify the software application. The method involves the creation of a computer-readable mapping between the first interface and the second interface. The computer-readable mapping is then run through auto-generation software which automatically generates an interface wrapper. The interface wrapper can be used in a system to allow a legacy application to continue to use a legacy interface while a new application uses a new interface. The interface wrapper allows the software application to transparently communicate with the second interface. The details of the auto-generation software are also specified.
