The WebSphere Configuration Migration Toolkit (WCMT) is an Eclipse plugin that reads your existing server configuration from either traditional WebSphere V7.0+, WebLogic, or JBoss and creates equivalent resources in a Liberty server.xml file and/or creates a Jython script that, when run, creates equivalent resources in traditional WebSphere.
Are you migrating from traditional WebSphere to Liberty or WebSphere V9? Instead of installing the plugin, try the new web tool. Same great configuration migration help, no installation required. Try the current beta: WebSphere Configuration Migration Toolkit: Web Version.
If you encounter any issues with the beta, please contact firstname.lastname@example.org and provide your configuration properties file.
