Performing initial upgrade or replacement tasks
Complete these initial installation tasks, which include saving the system. Several of these initial tasks are required for a successful IBM® i software upgrade.
- Choosing a software installation method and device
If you are upgrading the IBM i operating system and your licensed programs to the new release, you need to decide which installation method (manual or automatic) and which kind of device you will use to install the new release. - Preparing for globalization
If appropriate, prepare to change the primary language on your system or install additional secondary languages. - Preparing the upgrade device and media
You can prepare to install IBM i software from optical media, an image catalog, tape devices or tape libraries, or alternate installation devices. - Required: Creating a custom list of software to install
Use this Prepare for install option to create a customized installation list and preselect the IBM i licensed programs (including Licensed Internal Code and the IBM i operating system) that you want to install. This step is required to ensure the software agreements for the licensed programs are restored and displayed on the Work with Software Agreements display, which occurs later in the process. - Required: Accepting software agreements
As a continuation of using the IBM i Prepare for install option, you must accept the software agreements for licensed programs before they can be installed. - Ensuring the system meets disk storage requirements for upgrades
You must ensure that you will have adequate disk storage before you start to install or replace IBM i software. - Required: Allocating additional space for Licensed Internal Code
The IBM i 7.2 Licensed Internal Code requires more storage space than V6R1 and IBM i 7.1. If your system or logical partition does not have the additional space, the upgrade stops during the installation of the IBM i 7.2 Licensed Internal Code. IBM i 7.2 also requires a load-source disk that is 70 GB or larger. - Choosing disk configuration
If you are replacing the operating system and want to keep your current disk configuration, follow these steps. - Estimating upgrade or replacement time
You might want to estimate the time that is needed for an IBM i upgrade or replacement of your software. - Preparing your console for software installation
Before you install a new IBM i software release, consider this information about consoles. - Stopping the integrated server and other application servers
If you have IBM i integration with BladeCenter and System x installed, you must vary it off before you begin the IBM i installation process. Other applications servers should also be stopped before you upgrade your software.
