IBM WebSphere Application Server Migration Toolkit

The IBM® WebSphere® Application Server Migration Toolkit is a suite of tools and knowledge collections that enables your organization to quickly and cost-effectively migrate to WebSphere Application Server V7.0 through V8.5.5, whether from a previous version of WebSphere Application Server or competitive application servers including Apache Tomcat Server, JBoss Application Server, Oracle® Application Server, and Oracle WebLogic Server.

New and noteworthy:

  • Thinking about migrating to the IBM WebSphere platform? To ease your planning, IBM has launched the WebSphere Migration Discovery Tool. You can use this web-based tool anonymously and at no-charge to help gain insight into the size and scope of your migration project. This tool works for migrations to WebSphere Application Server, WebSphere Application Server Liberty profile, and WebSphere Application Server Liberty profile on IBM Bluemix™. Learn more about the tool in this WhyWebSphere blog.
  • Are you moving applications to a cloud environment? The Cloud Migration Tool and the Migration Toolkit for Application Binaries have support for the following cloud targets: Bluemix Instant Runtimes, third-party PaaS environments, Docker (IBM Containers), and WebSphere on Cloud (virtual machines). The tools provide a set of rules that help you analyze the impact of moving an application to the cloud based on the connections the application uses. Learn more about how these tools can help in this Migration article.
  • Do you want to scan application binaries? Check out our newest tool, the Migration Toolkit for Application Binaries! With this command-line tool, you can quickly evaluate application binaries for rapid deployment on Liberty or newer versions of WebSphere traditional.

The WebSphere Version to Version Application Migration Tool enables organizations deploying WebSphere Application Server V7 through V8.5.5 to more easily migrate applications from WebSphere Application Server V5.1 through V8. Upgrading to a more recent version of WebSphere Application Server is of course less time-consuming than migrating from another application server, given that IBM has made significant investments in upward compatibility, configuration, and management process upgrades, as well as API preservation and consistency between versions. However, in some cases, applications must be changed in order to support or exploit new levels of industry standard specifications delivered with new versions of WebSphere Application Server. The Application Migration Tool enables you to quickly and easily identify and implement any application changes required when upgrading to WebSphere Application Server V7 through V8.5.5.

The Application Migration Tools use the scanning capabilities of Rational Software Analyzer to locate application elements that should be updated in order to ensure optimal compatibility and performance with WebSphere Application Server V7 through V8.5.5, as well as unique editing features to review and appropriately change the code. The Application Migration Tools are packaged as features that can be installed into an Eclipse or IBM Rational Application Developer or IBM Rational Software Architect IDE. Figure 1 illustrates one of the Application Migration Tools.

Getting help and providing feedback


If your organization has a support agreement in place for WebSphere Application Server V7, V8, or V8.5, IBM will provide support for the Application Migration Tools as part of that support agreement. Support is provided for the tools and the included migration rules. Assistance with application coding or design issues would require a Services engagement.


You can use the Migration Toolkit Forum to ask questions, search for solutions, and provide feedback to the development team.
