Step 1: Plan your migration

Complete these steps before you migrate to WebSphere Application Server - Express.

1. Before you can migrate, you must install WebSphere Application Server - Express. For more information on installing WebSphere Application Server - Express, see WebSphere Application Server - Express installation in the Installation topic.

2. In addition to migrating your instances and applications, you also need to familiarize yourself with the tools and features of WebSphere Application Server - Express. The Administration topic describes administrative tasks and the tools that are provided to perform those tasks.

3. Evaluate the deprecated Version 5.1 items. For more information, see Deprecated Version 5.1 items.

4. Verify that you have the minimum prerequisites required for migration. For more information, see Migration prerequisites.

5. Evaluate the changes to API specification levels to determine what needs to be changed, if anything, in the applications that are to be migrated. Use these topics to plan your application migration requirements. For more information, see API and Specifications for version 3.5.x.
