Migration support consists of tools that are included with WebSphere® Application Server. These tools primarily provide support for saving the configuration and applications from a previous version of the product into a migration-specific backup directory and then importing that configuration into the latest version of the application server.
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.
