The IBM WebSphere Application Server Migration Toolkit – Liberty Tech Preview is now available to download. The Liberty Tech Preview tool helps you move WebSphere Application Server full profile applications to Liberty profile, which can be running inside or outside of the cloud.
The Liberty Tech Preview tool scans your application source code and highlights Java EE programming model and WebSphere API differences between the profile types. It offers advice and potential solutions to assess the ease of moving applications to Liberty profile. It also informs you about any implementation differences that could affect your applications. Where possible, it provides quick fixes to make the application changes for you.
When moving an application to the IBM BlueMix or other Cloud Foundry environment, the Liberty Tech Preview tool offers additional advice, suggestions, and best practices to ensure the application will run correctly. For example, it will warn about using the Java File I/O API for storing persistent information on the local file system or suggest using the IBM BlueMix SessionCache service for storing HTTP session data.
Liberty Tech Preview also provides a reporting tool that quickly scans your application and generates a report that shows which editions of WebSphere Application Server are best suited for the application. The report is an inventory of Java EE programming models that are used by the application. It indicates whether the application can be supported by WebSphere Application Server full profile or Liberty profile.
Liberty Tech Preview can be used in combination with the existing IBM WebSphere Application Server Migration Toolkit and can help in migrating applications from Apache Tomcat Server, JBoss Application Server, Oracle Application Server, or Oracle WebLogic Server to Liberty profile.
