InfoCenter Home > 3.1: Migrating product prerequisitesThe prerequisites Web page described in article 1.3 contains up-to-date information about the supported prerequisites and corequisites. Be sure to check whether your JDBC driver is at the right level for the new installation. This driver will be required by the product administrative server in order to connect to its administrative database. Migrating DB2, IBM HTTP Server, and other complimentary prerequisitesIBM WebSphere Application Server simplifies the migration of product prerequisites by providing the option to install a complimentary Web server, database, and JDK on your supported operating system. The JDK is the exact level and type needed by IBM WebSphere Application Server. See the installation guides for further details. The compact disc version of the product includes the complimentary prerequisites; Web download versions can vary (offered with and without database, and so on), to provide a choice of download file sizes. If not installing from CD, consult the product Web site for details. Make sure you download the installation package with the features you want. You can uninstall the back-level prerequisites and install brand-new versions when you install the product. Migrating non-IBM prerequisitesSome prerequisite or corequisite products, such as an Oracle or Sybase database, are not provided as part of the IBM WebSphere Application Server installation. To upgrade these, the best source of information is the documentation for the products. First, consult the previously cited prerequisites page to determine which software requires migration or upgrade. Second, consult the documentation for the particular products to learn how to migrate to the version supported by this product. For prerequisites not offered during the Application Server installation, the safest approach is to migrate or upgrade prerequisites before installing IBM WebSphere Application Server. |
