The Self Directed Migration Method

GCG needed to be closely involved with the migration process. Given their experience with the legacy system, the technical skills sets within their team and that they would continue to support their client, GCG chose CORE’s Self Directed Migration Method.

Core Migration’s Self Directed Migration Method is broken down into logical stages of the migration process. The CORE Migration team completed the initial stage of the migration process called Design Preservation. Once this stage was completed, CORE trained GCG’s staff on the Forward Engineering Toolkit which covers a broad spectrum of training from migration methodology from User Interface Training to deployment and maintenance management. During the Forward Engineering stage, GCG could access the repository from their site via a secure portal. The repository contained all the business logic and rules from GCG’s client’s application (populated in the Design preservation stage). GCG was able to use the forward engineering of the legacy source code, which is stored in the repository, to the target technology. The GCG team was able to easily follow the later phases of the migration from Unit Testing, Functional Testing, Acceptance Testing to Implementation.
