Before You Begin
Before you update to HP-UX 11i v2, make sure that:
• You are updating from a supported migration path. See “Supported
Update Paths to HP-UX 11i v2” on page 45.
• Your system meets the system requirements to update and operate
HP-UX 11i v2. For more details see Chapter 2, “System
Requirements for Cold-Installing and Updating,” on page 31.
• You have completed the preparation tasks required to update your
system. For more information see Chapter 4, “Preparing to
Cold-Install or Update to HP-UX 11i v2,” on page 69.
NOTE Updating from a release of HP-UX to a version of HP-UX that was
released earlier in time is not supported. For example, trying to update
from HP-UX 11i v1 December 2004 release to the HP-UX 11i v2
September 2004 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 v2
Installation and Update Guide for more information.
