Review the migration planning information. See Knowledge Collection: Migration planning for WebSphere® Application Server.
This task describes how to use the command-line tools to migrate cell topologies across operating systems from a previous version of WebSphere Application Server to Version 7.0 Fix Pack 7 or later. 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. This procedure assumes that the previous configuration is running and that you are migrating all profiles to a new host.
You have migrated from a previous version to WebSphere Application Server Version 7.0 Fix Pack 7 or later using the migration tools.
