Use the Migration wizard to migrate an earlier supported version of WebSphere® Application Server to Version 7.0.
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.
Before using the Migration wizard, you must have access to the existing, previous version of WebSphere Application Server.
Migrating a WebSphere Application Server Version 5.1.x or Version 6.x deployment manager to a Version 7.0 deployment manager moves all of the Version 5.1.x or Version 6.x federated nodes to become Version 5.1.x or Version 6.x federated nodes in the Version 7.0 cell. If you are migrating a Version 5.1.x or Version 6.x federated node that is part of a Version 7.0 cell to Version 7.0, do not federate the node when you create it with the Profile Management tool but do be sure that the Version 5.1.x or Version 6.x and Version 7.0 node names match. Migrating the Version 5.1.x or Version 6.x federated node to Version 7.0 also federates the node.
The Migration wizard was introduced in WebSphere Application Server Version 6.0. The wizard is the graphical interface to the primary Version 7.0 migration tools, the WASPreUpgrade command and the WASPostUpgrade command, which are command-line tools.
