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.

If you are not sure which installation device to use for your software upgrade, refer to Types of software installation devices. The topic Installation devices and media contains more detailed information on the devices and media available.

• Preparing to upgrade or replace software using an image catalog
  You can use an image catalog to perform a software upgrade, to install PTFs (fixes), or to install single licensed programs that you receive on media.
