Upgrade the operating system

You must ensure that your operating system meets the supported minimum level that is required for the new release of WebSphere Partner Gateway. Refer to Platform, hardware, and software requirements before continuing with the upgrade process.

Note:
For RedHat Linux, we recommend that you make a backup of existing installations of DB2, Oracle, WebSphere MQ, etc. before you upgrade the operating system. RedHat Linux does not support an upgrade from 2.1 to 3. You must uninstall 2.1 and then install 3. Please review the upgrade documentation for RedHat Linux 3.0.
