Coexistence support

Coexistence, as it applies to WAS products, is the ability of multiple installations of WAS to run on the same machine at the same time. Multiple installations include multiple versions and multiple instances of one version. Coexistence also implies various combinations of Web server interaction.

v6 WAS products can coexist with the following supported versions:

All combinations of V4.x products, V5.x products, and V6.0 products can coexist so long as there are no port conflicts.

V4.0.x and V5.x can coexist with the v6 WebSphere Application Server clients:

In addition to multiversion coexistence, WAS also lets you install multiple times on one machine (multiple installation instances), or install once and have multiple profiles.

Multiple V6 instances on one machine include:
