The migration tool provided by Branch Transformation Toolkit version 5.2 helps users of earlier versions move up to the full power and versatility of the IBM® WebSphere® Application Server and IBM WebSphere Process server. It provides the migration path to allow an enterprise to reuse much of its existing toolkit application code base and still take advantage of the WebSphere J2EE environment.
IBM recognizes that an enterprise cannot always upgrade its application software all at once. Because the enterprise can decide how much or how little toolkit functionality to retain, version 5.2 allows the enterprise to upgrade to a full J2EE environment incrementally. If desired, with version 5.2, the enterprise can bypass toolkit functionality entirely and access J2EE components directly.
This migration guide describes the migration considerations when you migrate to version 5.2 and the migration tool that helps you roll out the migrations. Note that the descriptions do not present all of the possible architecture variations available in each version.
