Coexistence support

Coexistence is a state in which nodes from different versions of WebSphere Application Server can start and run in the same environment at the same time.

Coexistence, as it applies to WebSphere Application Server products, is the ability of multiple installations of WebSphere Application Server 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.

Version 6.0.x WebSphere Application Server products can coexist with the following supported versions:
  • IBM WebSphere Application Server Advanced Server Single Edition and Advanced Edition Version 4.0.2 and later
  • IBM WebSphere Business Integration Server Foundation Edition Version 4.1 and later
  • IBM WebSphere Application Server Version 5.0 and later
  • IBM WebSphere Application Server Network Deployment Version 5.0 and later
  • IBM WebSphere Application Server Enterprise Version 5.0 and later
  • IBM WebSphere Application Server Version 5.1.0 and later
  • IBM WebSphere Application Server Network Deployment Version 5.1.0 and later

All combinations of Version 4.0.x products, Version 5.x products, and Version 6.0.x products can coexist so long as there are no port conflicts.

Version 4.0.x and Version 5.x can coexist with the Version 6.0.x WebSphere Application Server clients:

In addition to multiversion coexistence, WebSphere Application Server also lets you install multiple times on one machine (multiple installation instances) or install once and have multiple profiles. Multiple Version 6.0.x instances on one machine include the following combinations:
  • Multiple application server instances from multiple installations of the WebSphere Application Server product
  • Multiple Application Server profiles from a single installation of the WebSphere Application Server product
