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 on page 42 for supported update paths.
You cannot update between server Operating Environments and
technical Operating Environments.
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.
NOTE 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.
