Preparing to upgrade or replace software using an image catalog

 

You can use an image catalog to perform an i5/OS^® software upgrade, to install PTFs (fixes), or to install single licensed programs that you receive on media. When you use an image catalog, you preload all your media so that you do not need to handle the physical media when you perform the installation. You do this by copying the images from the physical media or from files received through electronic software delivery to a file in the integrated file system and then use these preloaded images to install. The topic Virtual optical storage describes further the concepts and uses of virtual optical media. Image catalog for a virtual optical device describes the requirements for using image catalogs.

You cannot use a virtual tape image catalog to install or upgrade an i5/OS release.
