Re: Solaris 10 upgrade question

We have purchased a Sun 2540 storage server which will be attached to
a Sun Fire V440 which is running out of room on several filesystems. The
440 is running Solaris 10 1/06. The release notes for the 2540 indicate that
Solaris 10 Upgrade 3 is needed, which I believe is the 11/06 release.

Probably a minimum requirement. Use update 4. Update 5 will soon be
released

Although we have had Sun machines in our shop for over 12 years, I have
never actually upgraded Solaris. All of my installs have been clean. So
I'm wondering what I have to look forward to. If upgrade 3 is required then
I should probably go ahead and download the latest Solaris 10, which is
8/07? I have read about Live Upgrade but that appears to need a spare disk
partition, which I don't have.

A minimum of one partition and large enough for the lot.

What can I expect if I just download the latest Solaris 10 and install it
on top of my existing Solaris 10? For example, will settings in /etc be
preserved? There are no zones involved. I will of course have a good backup
of /, /usr, and /var before starting. Thanks for any advice...

/usr should not be standalone ; /

You must have funding or budget problems.. You have the $$ for a FC/AL
array
and presumeably the HBA(s) but no $$ for another internal disk for
live_upgrade. Yuk.

What you really need is a test box that is capable of running Sol 10
u4. Then you can
answer such questions yourself. That aside you can generally safely
proceed through
the upgrade proceedure up to the point where you see a "This system
is upgradeable"
message. Not an exact quote but close enough. Prepare for downtime.
Possibly hours of it.
