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.
Before you begin
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.

Read Overview of migration, coexistence, and interoperability and Premigration considerations. For resources to help you plan and perform your migration, visit Knowledge Collection: Migration planning for WebSphere Application Server.
Important: Use the migration tools for the version of WebSphere Application Server that you are installing.
The tools change over time. If you use migration tools from an earlier
release of WebSphere Application Server, you are likely to encounter a problem with the migration.
The migration scripts are located in the app_server_root/bin directory after installation.
Procedure
Select the appropriate migration tools to migrate your
product configurations.
