What is Migration Assistant for IBM WebSphere Application Server, Community Edition?
This tool facilitates migration from IBM® WebSphere® Application Server, Community Edition, to the more advanced WebSphere Application Server family of products.
The migration assistant tool assists in migrating your Community Edition-developed applications and deployment plans over to WebSphere Application Server by removing a great deal of the complexity and manual intervention involved in migrating the vendor-specific deployment descriptors. When the tool is run against a Community Edition application (WAR or EAR) that can be migrated by the tool, an updated copy of your application will be created that contains the WebSphere Application Server binding files. In addition, if any manual migration steps must be performed (such as resource creation in WebSphere Application Server), those details and relevant pointers to WebSphere Application Server Information Center instructions will be provided in an HTML file.
The migration assistant is a Java™-based command line tool and is packaged as a simple TAR/ZIP bundle for Linux® or Windows® systems without an installer. WebSphere Application Server 6.1 is required because the tool depends on some WebSphere Application Server-provided libraries for creation of WebSphere Application Server deployment and binding files.
How does it work?
This initial release of the migration assistant tool is a command-line-only version and migrates only deployment descriptors from WebSphere Application Server, Community Edition 2.0, to WebSphere Application Server 6.1. Other deployment elements, such as database and JMS resources or external application-required artifacts, will be flagged in the tool's HTML output with pointers to the relevant WebSphere Application Server InfoCenter instructions and must be manually migrated by the user.
Currently, applications being migrated must be J2EE 1.4-compliant and use only Java SE 5 constructs. Use of Community Edition-specific features, libraries, or APIs (such as Java EE Annotations, ActiveMQ, or OpenEJB) must be manually migrated before using the tool.
