3.2.2: Migrating from Version 3.x

Before you start, be sure to read Transitioning to Version 4.0. That article outlines the reorganization of the Version 4.0 product relative to Version 3.x.

A summary of the product migration process follows. Most of this can be done for you by the product installation program.

  1. Back up the current administrative configuration and user data files in the current installation root directory. See 3.2.2.2.1 for more information.
  2. Stop and uninstall the current version of IBM WebSphere Application Server.
  3. Install the new version of IBM WebSphere Application Server.
  4. Restore the configuration in the new installation.

Note: If you have a Java Naming and Directory Interface (JNDI) client running on WebSphere Application Server Version 3.5.x that needs to access a Version 4.0.x name server, you need to ensure the following:

  • All 3.5 clients must be Version 3.5.3 or higher.
  • The WebSphere Application Server Version 3.5.3 and 3.5.4 installation on which the 3.5 client runs must have e-fix PQ51387 applied. Starting with 3.5.5, no e-fix is necessary.

Migrating administrative configurations

Tools for migrating administrative configurations are provided for versions 3.02 and later. This support enables either edition of Version 3.x to be upgraded to either Advanced or Advanced Single Server edition of Version 4.0. There are two ways to migrate from Version 3.x:

  • Use the automated migration that is part of product installation.
  • Manually complete the same steps as the automated migration support would. This might be necessary for nonstandard installations.
