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 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.
sptcfg 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.
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.
