This section covers all aspects of migration, upgrades, coexistence, and interoperability.
- Migrating is copying the configuration from a previous release of this product into a new release.
- Coexisting is running a new release of a WebSphere Application Server product on the same machine at the same time as you run an earlier release, or running two installations of the same release of a WebSphere Application Server product on the same machine at the same time.
- Interoperating is exchanging data between two coexisting product installations.
- Migrating WebSphere applications
- This section provides migration,
coexistence, and interoperability instructions that are specific to various
types of applications. For example, you can focus on moving Web applications
with the latest supported specifications; migrating Web services from Apache
SOAP; or integrating two types of messaging support.
- Migrating product configurations
- You can migrate administrative configurations with the Migration wizard or with the
command line migration tools, as this task describes.
- Migrating Web server configurations
- This topic describes what to do to migrate a Web server from supporting IBM WebSphere
Application Server, Version 4.0.x or V5.x, to support IBM WebSphere Application Server Network
Deployment, Version 6.
- Migrating administrative scripts
- WebSphere Application Server Version 6 supports migrating administrative scripts from V4.0.x and V5.x.
- Coexisting
- This topic is a starting point for finding information about which coexistence scenarios are supported,
and how to set up the scenarios.
- Interoperating
- WebSphere Application Server Version 6 is generally interoperable with WebSphere Application Server
Versions 4.0.x and 5.x. However, there are specific requirements to address for each version.
In general, IBM recommends that you apply the latest fix level to support interoperability.
If this is not possible, then the following interim fixes can be used to support your environment.
- Configuring ports
- This topic discusses configuring ports, particularly in coexistence scenarios.
- Troubleshooting migration
- This topic describes how to identify and handle a variety of problems
that are encountered during migration, interoperability, and coexistence activities.
