Installation Scenarios
- Installation Manager Version 1.8.5 or later is required to install the product.
- Hardware and software requirements for our operating system.
- Review installation scenarios...
- WebSphere Application Server Network Deployment product.
- Web Server Plug-ins for WebSphere Application Server
- Application Client for IBM WebSphere Application Server
- Optional: Review interoperability and coexistence scenarios to know what is possible with the current version.
WebSphere Application Server can interoperate with your other e-business systems, including other versions of WAS. Interoperability provides a communication mechanism for WAS nodes that are at different versions, running on separate machines. Coexistence describes multiple versions or instances running on the same machine at the same time.
Interoperability support enhances migration scenarios with more configuration options. Interoperating is often more convenient or practical during the migration of a configuration from an earlier WAS version to a later one. Some machines can have the earlier product version and other machines can have the later version. An environment of machines and application components at different software version levels can involve both interoperability and coexistence.
It is often impractical, or even physically impossible, to migrate all of the machines and applications within an enterprise at the same time. Understanding multiversion interoperability and coexistence is therefore an essential part of a migration between version levels. See the migration documentation for more information.
