Supported Update Paths to HP-UX 11i v2
Update means using the update-ux command and Software Distributor
(SD) tools 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.
Update is supported on HP HP 9000 systems and Itanium-based
Servers.
You can update to HP-UX 11i v2 from the following releases:
• HP-UX 11i version 1 (B.11.11)
• HP-UX 11i version 2 (B.11.23)
Updating from any other release directly to HP-UX 11i v2 is not
supported.
IMPORTANT The HP-UX 11i v1.6 update path has been discontinued with the
December 2005 release of HP-UX 11i v2. If you wish to update from
HP-UX 11i v1.6 to the December 2005 or later version of HP-UX 11i v2
you must cold-install HP-UX 11i v2.
Update Path Notes • You cannot downgrade to a lower level Operating Environment, for
example, from Enterprise OE (EOE) to Foundation OE (FOE).
• You cannot update between server Operating Environments and
technical Operating Environments.
