Checklist: IBM i software replacement
Use this checklist to complete all the tasks for a software replacement of the same IBM® i release.
If you plan to navigate through this checklist online, it might help to right-click this topic in the navigation tree to open a new window. The information in this checklist summarizes the major tasks that you need to do before you begin to replace your software.
Before you begin
- Verify that your server model meets the requirements
to support the new release. Use the following Web pages.
- The IBM Prerequisite Web page (www.ibm.com/eserver/iseries/support/e_dir/eserverprereq.nsf) provides you with operating system compatibility information for hardware features.
- The Upgrade planning Web page (www.ibm.com/systems/support/i/planning/upgrade/osmapping.html) has a table that indicates which releases of the operating system are supported by each of the server models.
Know your current strategy for connecting a console
to your system or logical partition. Your current connection strategy
influences your planning activities. For more information
about consoles, see Managing IBM i
consoles in the IBM Systems
Hardware Information Center.
- Plan for extra time after the upgrade to perform a server IPL. This is one of the tasks described in the Checklist: Completing the replacement of the same IBM i release.
- Understand system administration tasks (basic system operations). To perform software installation tasks, you need to be able to restart your system, sign on and off, use the command interface, install fixes, change the system operation mode and initial program load (IPL) source on the system unit control panel, and analyze system problems.
- Understand the different Types of software installation devices. The installation tasks are different based on the device type and media type that you use.
From the following checklist, perform the tasks that are appropriate for your system. Required steps are noted.
Software replacement tasks
- Verify the contents of your software order. For
more information about the optical media you received with your order,
see Media labels and their contents.
- Reviewing software PTF (fix) requirements
- Working with critical system values before you install software
- Ensuring two-phase commit integrity
- If you have a large number of spooled files on your system, set the compress job tables IPL attribute to none. To do this, use the Change IPL Attributes command: CHGIPLA CPRJOBTBL(*NONE).
- Gathering performance data for benchmark
- Preparing the upgrade device and media
- Preparing to upgrade or replace software using an image catalog.
- Determining storage requirements for image catalog installation
- Freeing up space on the load-source disk unit for an image catalog
- Preparing an optical image catalog to install software
- Determining storage space required for a replacement of the same release
- Preparing your console for software installation
- Stopping the integrated server and other application servers
- Saving the system
- Replacing software of the same release using manual installation
- Installing PTFs for the Licensed Internal Code and the operating system

After you finish
After the replacement tasks
in this checklist have been completed, consider these tasks.
- Develop a strategy for managing and maintaining your software. For information about software fixes (or program temporary fixes, PTFs), and software licenses and license keys, go to the topic Maintaining and managing IBM i and related software.
- For information about software distribution of supported products, go to the topic Distributing software.
