Abstract
A method for migrating legacy applications into a new software product architecture using a functional conversion module located within a system controller. The functional conversion module comprises a migration plan shut off. The functional conversion module further comprises three paths or branches through which a functional request can be routed. Functional requests which are not identified in the migration plan are routed through the first path and the functional request is sent to the pre-existing software and executed as requested. Functional requests identified in the migration plan for which the pre-existing software is in control are routed through the second path, and the functional request is sent to the pre-existing software and executed as received. In the background, the functional request is translated for the new software and sent to the new software and executed. Functional requests identified in the migration plan for which the new software is in control are routed through the third path, and the functional request is translated for the new software and sent to the new software and executed. If the pre-existing software has been shut off, the task is complete. If the pre-existing software is not identified as being shut off, the functional request is sent to the pre-existing software and executed as received in the background. Duplicate requests are suppressed by the system controller.
