Use the Migration wizard to migrate an earlier supported version of WebSphere Application Server to Version 6.0.x.
Before using the Migration wizard, you must have access to the existing, previous version of WebSphere Application Server, and you must also have a valid Version 6.0.x profile.
The Express product creates a valid Version 6.0.x profile for a standalone application server during installation.
A unique error can occur when migrating a previously federated Version 5.x node to a standalone Version 6.0.x node. If you unfederate an application server node from a Version 5.1.0 or earlier cell, see the Migrating a Version 5.x application server to a Version 6.0.x standalone application server profile after unfederating the Version 5.x node fails with a node name mismatch error technote for more information before using the Migration wizard.
The Migration wizard is new as of Version 6.0. The wizard is the graphical interface to the Version 6.0.x migration tools, the WASPreUpgrade command and the WASPostUpgrade command, which are command-line tools. This article describes how to use the Migration wizard to perform migrations to Version 6.0.x.
