Selecting the Path to HP-UX 11i
You should update rather than cold-install HP-UX 11i when you are
updating from HP-UX 10.20 or 11.0 and:
• You are only updating a few (1-3) systems to 11i.
• You are concerned about recovering unique applications and data on
your root volume, such as custom desktops or applications, that are
hard to restore. The update-ux command will not write over non-OS
files when installing 11i.
• Each system has a unique configuration.
• Current disk space is sufficient for 11i (see page 20).
If your system meets these requirements, follow the update procedure in
Chapter 2.
update-ux removes all 10.x patches from the system prior to updating to
11i. Any 10.x applications left on the system after the update may not be
supportable if they required those patches. After migrating your system,
see instructions for each remaining application to update it to 11i.
Installing or updating to HP-UX 11i will install a minimum set of default
networking drivers that apply to the system (see the top part of the table
at the end of Chapter 2). You may need to select or specify other available
networking drivers to enable other cards on your system. This can easily
be done during the install or update by following the instructions in
Chapter 2.
If you plan to update Netscape Directory Server (NDS) along with
HP-UX 11i, see Chapter 2 for details. The update-ux command does not
replace NDS with a new version by default.
If the Distributed File System (DFS) is installed and in use on your
HP-UX 10.20 system to manage large numbers of files, update-ux will
remove it and associated data during the update to 11i. If you need to
continue using DFS, do not update to HP-UX 11.x or 11i.
If you system already is running any version of the Apache Web Server,
installing or updating to an HP-UX 11i Operating Environment will not
install the version of Apache included with the 11i OE. If you wish to
install the version of Apache provided with HP-UX 11i, you should
