Overview |
With migration, the new product or new version of the product is installed alongside the older product. Then, data is copied from the old version of the product to the new version of the product. Migrating is different from updating, in which out-of-date files or data of an existing installation are replaced with current information. Refresh packs, interim fixes, and fix packs are examples of updates. For more information on updating, see Installing Maintenance Packages.
You must migrate your existing applications and configuration information from the previous version of WebSphere ESB to the newer version of WebSphere ESB in order to use them in the new environment.
