This manual covers HP-UX 10.20, Additional Core Enhancements (ACE)
and Hardware Extensions "cold" installations and updates, as well as
updates from 10.x to 10.20.
• Cold install means installing system software on a new (uninstalled)
or existing system disk in such a way as to completely erase old data.
See Chapter 2, “Installing HP-UX,” for the cold install procedure for
HP-UX 10.20.
• Update, for HP-UX 10.x, means using the SD-UX tools to install new
OS or application software from a media or network source depot. See
Chapter 3, “Updating HP-UX,” for the procedure for updating 10.x to
10.20. Use the tool swlist with your install depot to obtain current
information on bundle and product contents.
• Upgrade means using the 9.U3 tools and procedures to update your
system from a pre-10.0 version of HP-UX to 10.01. The SD-UX tools
are then used to update from 10.01 to 10.10 or 10.20. Information
about utilities and procedures for upgrading your system from
HP-UX 9.0x systems is covered in the manual Upgrading from
HP-UX 9.x to 10.x and in the Release Notes for this software (online in
/usr/share/doc).
