WebSphere Application Server - Express migration leverages the existing environment and applications and changes them to be compatible with the WebSphere Application Server - Express environment. Existing application components and configuration settings are applied to the WebSphere Application Server - Express environment during the migration process.
Migration involves modifying your applications so that they run in WebSphere Application Server - Express and then migrating those applications and your environment to WebSphere Application Server - Express. The latter step can be performed by using the migration tools shipped with the product.
Migration Tools
Product migration functions are provided by the the WebSphere Application Server migration tools. These tools perform migration from Version 3.5.x and from WebSphere Application Server - Express Version 5.0.x to WebSphere Application Server - Express Version 5.1. The migration tools are comprised of the following commands:
The following tools are also available to assist you in migrating your applications:
MigrateWC converts JSP Specification .91 or 1.0 application components to JSP Specification 1.1 components. It also converts Servlet 2.1 specification components to Servlet 2.2 specification components. The converted components are written to a new file. This tool is not shipped with WebSphere Application Server. For more information and to download this tool, see the WebSphere Developer Domain . Search in the Downloads section for MigrateWC.
CACT analyzes compiled servlet and enterprise bean Java class files and provides information on any API that is deprecated or not supported in WebSphere Application Server Version 4, Version 5, or Version 5.1. This tool is not shipped with WebSphere Application Server. For more information and to download this tool, see the WebSphere Developer Domain . Search in the WSDD Library section for CACT.
WebSphere Development Studio Client (WDSC) is part of the WebSphere Studio family of application development tools. This tool can be used to import your application source files, set the desired J2EE version in the product, for example to J2EE Version 1.3, and rebuild the source files. Use of changed, not supported, and deprecated APIs are reported through compilation errors. After it is built, the application can be tested with the version of WebSphere Application Server that is included with the tool.
