HP-UX 11i v3 Installation and Update Guide, March 2012

• Each system has a unique configuration.
• Current disk space is sufficient for HP-UX 11i v3. Note, however, that you can use Dynamic
Root Disk to address disk space limitations that would otherwise prevent you from updating.
See “Determining disk space requirements” (page 10).
An advantage of performing an update is that it leaves user data, configuration, and applications
in place.
Updating to HP-UX 11i v3 is limited to the supported paths listed in “Supported update paths”
(page 18).
For information about choosing installation and update sources, see “Choosing an installation
source” (page 19).
See Chapter 4: “Before you begin” (page 21) for details on how to prepare your system to update
to HP-UX 11i v3. The update process is described in Chapter 6: “Updating to HP-UX 11i v3”
(page 44).

Table 5 lists the supported update paths from HP-UX 11i v2 to HP-UX 11i v3 and from the original

Update path notes
• You cannot downgrade to a lower-level Operating Environment.
• Updating from a release of HP-UX to another release of HP-UX that was released earlier in
time is not supported. For example, trying to update from HP-UX 11i v2 June 2007 release
to the HP-UX 11i v3 February 2007 release is not supported. This could cause system
incompatibilities and unpredictable results. If you attempt to update to an earlier version of
HP-UX, the update process will stop without making any changes to your system and you will
get the following error message:
ERROR: You are attempting to update from your release of HP-UX to a
version of HP-UX that was released earlier in time. This is not supported.
The update process has stopped without making any changes to your system.
