Installing HP-UX 11.0 and Updating HP-UX 10.x to 11.0 HP 9000 Computers Edition 1

Updating an Existing Operating System and Software
Updating HP-UX Software
Example of Update Path 11.0 64-bit (K460 System). For
example, suppose you are running HP-UX 10.20 on a K460 system
(PA8000, which does support 64-bits), and you want to update to HP-UX
11.0 64-bit. You would perform the following steps:
1. Upgrade firmware on K460 (if not already compatible).
2. Update HP-UX 10.20 directly to HP-UX 11.0 64-bit version.
Transitioning Between Versions
Once HP-UX 11.0 is running on your system, you can transition between
the 32-bit and 64-bit versions of the operating system. If you are
updating from HP-UX 11.0 32-bit to HP-UX 11.0 64-bit, the transition
should be straightforward. However, before switching from HP-UX 11.0
64-bit to HP-UX 11.0 32-bit, you will need to ensure that all applications
can accommodate the change. If any 64-bit applications have written
binary data files (for example, 64-bit ELF executables), there may
compatibility issues when you switch back to the 32-bit version of the
operating system.
NOTE If you transition between 32-->64 bits or 64-->32 bits, you will need to do
the swgettools process. See “Updating SD-UX Before
Installing/Updating Software”in this chapter.
See the HP-UX 11.0 Release Notes and the Application Interoperability
White Paper for more information.
