3.2.1: Migrating from Version 2.0x

Two main paths are available for migrating from Version 2.0x.

Version 2.0x > Version 3.0x > Version 3.5 or higher

IBM WebSphere Application Server provides automatic migration from versions 3.02 or later. Migrating to Version 3.02 from versions 3.0 or 3.01 is fairly trivial based on upgrade options added to the Application Server installation program. For documentation about migrating from Version 2.0x to Version 3.0x, see the Related information.

Install product as new and migrate files and settings by hand

Uninstall Version 2.0x and start new with this version, transferring application files and configuration settings by hand.

Earlier versions of this product differ dramatically in terms of supported programming specifications, file placement, and administrative settings. In the absence of a comprehensive automated migration tool from Version 2.0x to Version 3.0x, the effort required to migrate to this version by way of Version 3.0x varies little from the effort required to install the product from scratch.
