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: 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 that 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.
Procedure
- Install WebSphere Application Server
Version 9.0.
- Familiarize yourself with the tools and features of WebSphere Application Server
Version 9.0.
- Verify that you have the minimum prerequisites required for migration.
-
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.
- 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.
- Evaluate the changes to configuration settings.
