Phase 3: Migrating your applications

After you have selected the correct configuration files, you can use the migration tool to migrate your applications.

Before you begin

Before you migrate your applications, you must make sure that you have selected the correct configuration files. For more information on selecting the correct configuration files, refer to the Phase 2: Customizing the migration tool section.

Procedure

To migrate you applications from IBM WebSphere Multichannel Bank Transformation Toolkit version 4.3 to version 8.0, do the following steps:

  1. Replace the WebSphere Multichannel Bank Transformation Toolkit version 4.3 JAR files with WebSphere Multichannel Bank Transformation Toolkit version 8.0 JAR files, and change the build path of the project to the new JAR files.
  2. Import the application that you want to migrate to the workspace as a project, and configure the migration tool. The migration tool will migrate the application directly based on the original project
  3. Migrate the dse.ini configuration file to btt.xml. Because the configuration file in WebSphere Multichannel Bank Transformation Toolkit version 4.3 is dse.ini, the migration tool migrates the dse.ini file to btt.xml.
  4. Migrate the definition files of the context, the data element, the type data, and the format.
  5. 5. Migrate the business logic. WebSphere Multichannel Bank Transformation Toolkit version 8.0 uses process, operation, and operation step as channel aware business logic, which is similar to WebSphere Multichannel Bank Transformation Toolkit version 4.3. In WebSphere Multichannel Bank Transformation Toolkit version 8.0 the architecture is refined and some components have been redesigned, so the package names, class names, and some APIs in WebSphere Multichannel Bank Transformation Toolkit version 8.0 are different from those in WebSphere Multichannel Bank Transformation Toolkit version 4.3. The migration tool will automatically migrate these differences.
  6. Manually migrate the components that cannot be completely migrated by the migration tool.
