UNIX for Dummies Questions & Answers

Hello,

First of all I don't know much about the different between sun or Solaris

This is my scenario

We have 6 WS and server running DNS, Oracle DB and Apache server. I type uname -a -- the result is
"SunOS omjs06 5.6 Generic_105181-13 sun4u sparc SUNW,Ultra-2"

I guess now we are using Solaris 2.6 anyway I just want to know if I want to upgrade our entire machines to Solaris 8.

1. How I can do that since I never done upgrade before.
2. How I can make sure that the upgrade will not affect the current setup. In windows2000 there's a utility to check the upgrade and compatibility of the software is there's such thing in UNIX

Thanks in Advance

I have been told that the solairs 8cd offers upgrade and cold install, I have also been informed that the CD offers 5.6 to 8 upgrade.
