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.

Configuration migration support is included within the WebSphere Application Server product. The associated tools are provided on all operating systems supported by WebSphere Application Server. This includes distributed, z/OS, and IBM i platforms.

The Configuration Migration Tools do not alter the configuration of your existing WebSphere Application Server installation. The tools provide a two phased approach to migration. First, the configuration from your existing WebSphere Application Server is copied into a backup directory. Second, the content of the configuration backup directory is merged into a new profile residing in your new WebSphere Application Server installation. By default, all of the configuration objects, including servers, resources, virtual hosts, etc, are merged into the new profile. In addition, all applications are repackaged from your existing WebSphere Application Server configuration and are installed into the new profile residing in your new WebSphere Application Server installation. An intuitive migration wizard is provided to walk you through the migration process. See Figure 2.
