Upgrading i5/OS and related software

Complete the steps to upgrade your i5/OS® and related software.

If you are upgrading to an IBM® Power Systems model, you must install the correct level of software and firmware on the source server. To determine the correct level of software and firmware you need, see the IBM Prerequisite.

In addition to upgrading to i5/OS version 6 release 1, you might also need to install related licensed programs on the source server.

To perform an initial program load (IPL) from Storage Area Netwrok (SAN), you must have installed the latest i5/OS version 5 release 3 modification 5 or V5R4 Licensed Internal Code (or later), which requires the 17 GB minimum load-source requirement. For more information about the load source requirement and to complete your upgrade of i5/OS and related software applications, see Upgrading or replacing i5/OS or related software.

To finish completing the software upgrade, perform the following tasks:

  1. To verify that all applications are running properly, use the server with the new software release operating with the new production environment. Use the server for a minimum of two weeks in production on your existing configuration before the hardware upgrade is performed.
  2. Complete the tasks located at Managing job logs and server Messages. Use this information to help you identify and fix any problems that might occur with the newly installed software.
