Migration guide from BTT version 5.2 to BTT version 6.1.2

This migration guide provided by Bank Transformation Toolkit (BTT) version 6.1.2 helps users of BTT version 5.2 move up to the full power and versatility of IBM® WebSphere® Application 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, BTT version 6.1.2 enables the enterprise to upgrade to a full J2EE environment incrementally. With BTT version 6.1.2, the enterprise can bypass the toolkit functionality and access J2EE components directly upon requests.

BTT version 6.1.2 provides a migration tool that helps you to migrate your applications. The tool can migrate BTT version 5.2 definitions to BTT version 6.1.2 definitions and migrate BTT version 5.2 class packages and APIs to the corresponding BTT version 6.1.2 class packages and APIs.

This migration guide describes the concepts that you need to know before you migrate your applications to BTT version 6.1.2 and the tasks you need to take to roll out the migrations with the migration tool.
