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.

This task describes how to migrate each profile in a cell configuration from a previous version of WebSphere Application Server to WebSphere Application Server Version 8.5 hosted on a different machine. The cell configuration consists of a deployment manager with one or more nodes, a web server, and an application client. All ports are migrated forward into the new configuration. The source and target host machines do not need to run the same operating system.
If WebSphere Application Server Version 8.5 is not installed on the source host machine, you must generate a remote migration .jar file on the target host machine that matches the operating system of the source machine. The remote migration .jar file provides the source host with the Version 8.5 WASPreUpgrade tool, which you use to create the migration backup directory for the profile.
This procedure assumes that the previous configuration is running and that you are migrating all profiles to a different host machine.
You used the migration tools to migrate the cell configurations from a previous version of WebSphere Application Server to new host machines that run WebSphere Application Server Version 8.5.
