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, V8, or V8.5, 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: The toolkit team has refreshed all five of the Application Migration Tools to version 3.5.3. See the WebSphere Application Migration Toolkit Version 3.5.3 forum topic for details on what's new and changed.
The Tomcat Config Migration Tech Preview tool is available to help migrate your Tomcat configuration to the WebSphere Application Server Liberty profile. Learn more at wasdev.net.
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.
