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.
This topic 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 Migration Toolkit.
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 or virtualized partition at the same time. Multiple installations include multiple versions and multiple instances of one version. Coexistence also implies various combinations of web server interaction.
All combinations of Version 6.1 or later and Version 8.5 products can coexist so long as there are no port conflicts.
WebSphere Application Server Version 6.1 or later clients can coexist with Version 8.5 clients.
