Live Upgrade like new install?
pretzel
They have been very heavily patched over the past few years, probably
way more than necessary (i.e., almost every patch, as opposed to just
Recommended & Security). There are no problems, but I am thinking
that it might be time for a fresh install, to be followed by patching
with only R&S patches, plus any that are specifically needed.
But, I don't want to reinstall the other software. (I'm lazy.) If I
use Live Upgrade to create an upgraded boot environment from the
Solaris 10 05/09 media, will I have the equivalent of a newly built
system, based on Solaris 10 05/09, and with all the existing software
intact?
Thank you.

What you propose is a poor idea. "If it ain't broke, don't fix it!"
You are not being paid to "twiddle the knobs" and push the buttons! You
are being paid to keep your system(s) UP! ANY change has a risk attached.
Digital Equipment Corporation used to use a patch classification system.
Class 1 patches were to be applied by everyone, right now! Class 2
were to be applied at your "earliest convenience". Class three "when you
get around to it" and class four only if you experienced the problem the
patch was supposed to fix.
If a patch is a "security patch" do it as soon as you can. Ditto if it
fixes a problem you have. Otherwise, let someone else debug it.

Richard's advice is sound -- if it ain't broke, don't fix it.
Except if the machine is exposed to the Internet, be sure to
apply all security patches. The world is a dangerous place.
But, just FYI to answer your question, if you get fresh
installation media, then yes, it gives you the option to do
either an overwrite install which wipes everything, or an
upgrade install, which will overwrite the OS but leave
everything else alone.
But make backups of everything anyway, just in case.

But in fact, what he is proposing is to *stop* having a bunch of random
patches as he has at the moment, and to move to a principled,
recommended&security-patches-only configuration, which will be much
closer to configurations that have been tested by Sun.
So, um?

That is precisely my thinking.
It was our Sun VAR that suggested that we do a new install (to "wipe
out" the 2.000 or so patches that have been previously installed).
I was just wondering whether there was any difference between using
Live Upgrade (which I assume is equivalent to an upgrade install from
the actual media), and a clean install from a newly formatted disk
followed by installation of all the app s/w.
Thank you.

An LU is indeed pretty much equivalent to an upgrade install: the main
difference is that with LU you have a very quick backout (which is, of
course, a huge benefit), and the outage is much smaller. However, if
you are after a really clean install I would be tempted to do a fresh
install.
