Migration Toolkit

IBM Application Server Toolkit
The Application Migration tool in the IBM WebSphere Application Server Migration Toolkit helps you easily move applications from a source application server to WebSphere Application Server v7.0, v8.0 or v8.5. Source application servers currently supported include WebLogic Server, JBoss Server, Oracle AS and Tomcat. The Application Migration plug-in works on an imported EAR file. The tool scans the JSPs, Java™ source code, and deployment descriptors for porting issues and reports these issues in the Problems view in your Eclipse-based IDE. Most of the porting issues that you could encounter will be identified by the tool and, in many cases, the tool will offer a quick fix to resolve them.

Webcast replay: Simplifying Migrations with the WebSphere Application Server Migration Toolkit
The WebSphere Application Server Migration Toolkit helps application developers move their applications from older versions of WAS to WAS v7, v8.0 or v8.5. It can also migrate applications running on a non-IBM application server to WAS. The tool scans application code, flags and fixes potential migration problems. This WebSphere Support Technical Exchange is designed to provide education on the toolkit and its usage.

IBM Application Server Toolkit Forum
The IBM WebSphere Application Migration Toolkit provides a way to help assist you doing competitive application server application migrations. This forum is for technical discussions supporting the IBM WebSphere Application Migration Toolkit. This forum is monitored by the tools development team.

Troubleshooting and Support

Collecting data (MustGather)
When a solution cannot be found to your migration problem, you can begin collecting data (MustGather) before calling IBM support. This will help you familiarize yourself with the troubleshooting process and save you time.

Exchanging information with IBM Technical Support
To diagnose or identify a problem, it is sometimes necessary to provide Technical Support with data and information from your system. In addition, Technical Support might also need to provide you with tools or utilities to be used in problem determination.
