Performing initial upgrade or replacement tasks

Complete these initial installation tasks, which include saving the server. Several of these initial tasks are required for a successful software upgrade.

• Choosing a software installation method and device
  If you are upgrading the 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 server or install additional secondary languages.
• Preparing the upgrade device and media
  You can prepare to install 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 the Prepare for install option to create a customized installation list and preselect the licensed programs that you want to install.
• Required: Accepting software agreements
  As a continuation of using the Prepare for install option, you must accept the software agreements for licensed programs before they can be installed.
• Ensuring the server meets disk storage requirements for upgrades
  You must ensure that you will have adequate disk storage before you start to install or replace software.
• Required: Allocating additional space for Licensed Internal Code
  The V5R4 Licensed Internal Code requires more storage space than in previous releases.
• Choosing disk configuration
  If you are using automatic installation to upgrade and do not want nonconfigured disk units added, PTFs are available that enable you to set your disk configuration option.
• Estimating upgrade or replacement time
  You might want to estimate the time that is needed for an upgrade or replacement of your software.
• Preparing your console for software installation
  Before you install a new software release, consider this information on consoles.
