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 PA-RISC Servers and Itanium-based Servers
and Workstations. Update is not supported on HP 9000 PA-RISC
Workstations.
You can update to HP-UX 11i v2 from the following releases:
• HP-UX 11i version 1 (B.11.11)
• HP-UX 11i version 1.6 (B.11.22)
• HP-UX 11i version 2 (B.11.23)
Updating from any other release directly to HP-UX 11i v2 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), or
from Technical Computing Operating Environment (TCOE) to
Minimal Technical Operating Environment (MTOE).
• You cannot update between server Operating Environments (FOE,
EOE, and MCOE) and technical Operating Environments (MTOE
and TCOE).
