Preparing for product-configuration migration

You must prepare your system for migrating to WebSphere® Application Server Version 9.0.

Before you begin

Read Overview of migration, coexistence, and interoperability and Migration considerations.

For help, read Troubleshooting migration.

Best practice Best practice: Rather than manually looking through your applications for API and specification changes, scan your applications for any required changes by using the Migration Toolkit for Application Binaries and the WebSphere Application Server Migration Toolkit.

The application binary scanner provides a detailed migration analysis report for your application, so you can better understand the type and scope of changes that the application might require. When you migrate your applications, the Eclipse-based migration toolkit provides quick fixes to automatically update your source when possible and provides detailed help for items that must be manually updated.

For more information and to download the toolkit, see the Migration Toolkit on WASdev.

Procedure

  1. Install WebSphere Application Server Version 9.0.
  2. Familiarize yourself with the tools and features of WebSphere Application Server Version 9.0.
  3. Verify that you have the minimum prerequisites required for migration.

    For more information, read Checking for the product-configuration migration prerequisites.

  4. Evaluate the items deprecated in WebSphere Application Server Version 9.0.

    Use the Migration Toolkit to scan your applications for any deprecated technologies. Alternatively, you can manually evaluate your applications.

    For more information, read the Deprecated and removed features article in the documentation.

  5. Evaluate the changes to API specification levels to determine which applications you need to migrate.

    The Migration Toolkit is the quickest and easiest way to evaluate your applications for any specification changes.

    For more information about specification changes, see Migrating APIs and specifications.

  6. Evaluate the changes to configuration settings.

    For more information, read Configuration mapping during product-configuration migration.
