Coexistence support

Coexistence is a state in which multiple installations and multiple nodes from different versions of WebSphere® Application Server run independently in the same environment at the same time.

Supported configurations Supported configurations:

This article is about configuration migration, such as migrating deployment managers and federated nodes in a network deployment environment. The Application Migration Toolkit for WebSphere Application Server provides support for migrating applications from previous versions of WebSphere Application Server to the latest product version. For information about migrating applications, read more about the Application Migration Toolkit.

[IBM i] As it applies to WebSphere Application Server products, coexistence primarily refers to the ability of multiple installations of WebSphere Application Server to run independently 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.

[IBM i] WebSphere Application Server Version 8.5 products can coexist with the following supported versions:
  • WebSphere Application Server Version 6.1 or later
  • WebSphere Application Server, Network Deployment Version 6.1 or later

[IBM i] All combinations of Version 6.1 or later and Version 8.5 products can coexist so long as there are no port conflicts.

[IBM i] WebSphere Application Server Version 6.1 or later clients can coexist with Version 8.5 clients.

[IBM i] 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 8.5 installation instances on one machine include the following combinations:
  • Multiple application server profiles from multiple installations of the WebSphere Application Server product
  • Multiple application server profiles from a single installation of the WebSphere Application Server product
