Unlike most manuals, this book is meant to be read from start
to finish.
This does not mean you have to read every word and do every
task, but it does mean you should go through each chapter of the
book in order, understand each topic and decide whether that topic
requires action on your part for the system or systems you need
to upgrade.
If you do this, and you do the necessary preparation, your
upgrade should be smooth and trouble-free.
Start the tasks in this manual after you have read the "I/O
Convergence" section of the Release Notes for HP-UX 10.10.
If you have not already retrieved the Release Notes
from the "HP-UX Upgrade Tools" tape or CD, you can find instructions
for doing so under “Locating and Loading Tools and Documentation”
in Chapter 4 of this manual.
