HP-UX 11i v3 Installation and Update Guide, September 2007 (Update 1 Release)

Supported Update Paths to HP-UX 11i v3
Update means using update-ux to selectively overwrite the operating system and
application software from a media or network source depot.
An advantage of performing an update is that it leaves user data, configuration, and
applications in place.
You can update to HP-UX 11i v3 from HP-UX 11i v2 (B.11.23). Updating from any other
release directly to HP-UX 11i v3 is not supported.
Update Path Notes
• You cannot downgrade to a lower level Operating Environment, for example, from
Enterprise OE (EOE) to Foundation OE (FOE). See Table 3-1 (page 34) for supported
update paths.
• You cannot update between server Operating Environments and technical
Operating Environments.
• 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. Please see the 'Supported
Update Paths' section of the HP-UX 11i v3 Installation and Update
Guide for more information.
.
NOTE: Updating from HP-UX 11i v1 to HP-UX 11i v3 is not supported. You must
first update to an HP-UX 11i v2 Operating Environment. Please see the HP-UX 11i v2
Installation and Update Guide for information on how to update from HP-UX 11i v1 to
HP-UX 11i v2. In addition, make sure your system meets the minimum system and
disk space requirements before updating from HP-UX 11i v2 to HP-UX 11i v3.
If VxFS 5.0 has been used to create file systems with disk layout version 7, those disks
will not be readable by the VxFS 4.1 that ships with HP-UX 11i v3. Before updating to
HP-UX 11i v3, copy data from your DLV 7 file systems and onto file systems created
at layout version 5 or 6.
