Phase 1: Analysis and preparation

In this phase, you need to analyze the differences between IBM® WebSphere® Multichannel Bank Transformation Toolkit version 4.3 and WebSphere Multichannel Bank Transformation Toolkit version 8.0, especially the application logic layer.

About this task

You must identify the parts of IBM WebSphere Multichannel Bank Transformation Toolkit version 4.3 that can be migrated automatically and the parts that cannot be migrated automatically, and then make necessary preparation for the migration. To prepare for the migrate, you must do the following tasks:
  1. Gather all the definition files of the existing application system version 4.3. The migration tool can migrate the definition files on the server side from WebSphere Multichannel Bank Transformation Toolkit version 4.3 to version 8.0. The migration tool can process the definition contents based on the predefined rule. All unknown tags are copied to the new definition files, which may not is the correct place for new application. In this case, you need record the changes and manual review.
  2. The migration tool can migrate Java code of the business logic of your applications to WebSphere Multichannel Bank Transformation Toolkit version 8.0. WebSphere Multichannel Bank Transformation Toolkit version 8.0 uses the processor, operation, and operation step on the server side of WebSphere Multichannel Bank Transformation Toolkit, which is the same as in WebSphere Multichannel Bank Transformation Toolkit version 4.3. The differences are in package names, class names, and changes of APIs. The migration tool can migrate WebSphere Multichannel Bank Transformation Toolkit version 4.3 classes and APIs to the corresponding WebSphere Multichannel Bank Transformation Toolkit version 8.0 classes and APIs.
  3. Migrate WebSphere Multichannel Bank Transformation Toolkit version 4.3 services. The services that are supported by WebSphere Multichannel Bank Transformation Toolkit version 8.0 on the server side does not support all of the WebSphere Multichannel Bank Transformation Toolkit version 4.3 services, and the SNA LU0/6.2 communication services are changed to JCA connectors. You must find a substitute solutions for these unsupported services or implement a new service based on the new service architecture. For example, IBM Lotus Notes® support. The migration tool can migrate the server side service definitions with customized migration rules, but you must find a solutions for the unsupported services.
  4. The event mechanism is changed to fit the WebSphere Multichannel Bank Transformation Toolkit version 8.0 framework so that it can be distributed and span different servers. However, the event mechanism is still compatible with the event mechanisms of all releases of WebSphere Multichannel Bank Transformation Toolkit version 4. You must decide if they override the standard client server event code and standard.
  5. Migration does not include Swing to WebSphere Multichannel Bank Transformation Toolkit XUI migration. You can select to stay with Swing or produce a migration roadmap with WebSphere Multichannel Bank Transformation Toolkit support.
