Migration guide from version 5.1 to version 5.2

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 tool is to migrate BTT 5.1 definition to BTT 5.2 base definition. It generates the corresponding program codes and the BTT version 5.2 tooling artifact. There are two ways for the migration: It provides you interfaces to help you migrate the BTT 5.1 application to BTT 5.2 one by one. It can also provide the capability for you to build your own batch migration application by using a set of definition files. Furthermore, the migration tool can delegate the migration process to the plug-in custom code to perform the customer unique extension.

This migration guide describes the migration considerations when you migration to version 5.2 and the migration tools that help you roll out the migrations. Note that the descriptions do not present all of the possible architecture variations available in each version.
