Hi gurus,
Can I use Jumpstart method to upgrade the OS on a prod machine which
is currently running Solaris 2.6 ??

My Jumpstart server is currently loaded with Solaris 8 image.

If yes, how do I do it ??

Appreciate your advice. Thanks.

Regards,
Francis.

Yes, assuming you have a Jumpstart server.

It's all explained in the Installation docs...

I would recommend practising on a machine that isn't
your production server first, though!

Is there a reason you need to use jumpstart? Setting up and testing
out jumpstart takes some time. It pays off when you need to maintain
several machines and if need an ability to reinstall them or add new
machines quickly when necessary. If you have just one or a few boxes,
performing a normal upgrade is probably going to be a lot easier.

Certainly. You can even upgrade to Solaris 8 in the process. You want
to being running Solaris 8, right?

Or do you mean you need to be able to install both versions on your
jumpstart server? Use a separate tree for the different versions and
go through the same sort of set-up process to be able to have both
versions. The clients use bootparams, so bootparams will point into
the different versions.

The key word is production. In production repeatabilty, design and
disaster recovery are key. If you can reduce a server to jumpstart
installability you have acheived all 3 at the push of a button.

He already has one. It's a question of upgrading the server in
question vs being able to jumpstart either version.

In production repeatability, design and DR all beat easy. Your
statement is true, but it applies to non-production systems.

The key word is actually `upgrade', I think. It tends to be hard (and
generally futile) to do repeatable upgrades. In order to reinstall
the server this way you would presumably have to jumpstart solaris
2.6, customise it (probably in the jumpstart), *then* do a jumpstart
upgrade to 8. Yuck! Much better, I think, to get things set up so
you can take a cold machine and jumpstart it to 8 in one go including
any customisations. That's what we always try and do anyway -
sometimes we do upgrades on machines that are clones of production
ones but usually only to find out what customisations we've missed.

I agree completely about using JS as a way of getting repeatability &c
even for only a small number of machines, I just question the desire
to do an upgrade rather than an initial install.

Is there a way to combine Live Upgrade and JumpStart?

That way if something goes 'kapoch', you can go back to the old
version. (Of course, you'll test to make sure everything works just
fine...)

There probably is. Actually what I want (which there probably is a
way to do) is a `live initial install' program.

You could do this by having a begin script which copied the old system
partitions onto the disk-to-be-installed-on, editing some suitable
stuff, I guess, then getting jumpstart to ignore the old disk. I guess
the `editing some suitable things' bit is hard though, and what live
upgrade does (well, tries to do).

Live upgrade will work with Flash Archives, I do not know if it will
work with jumpstart off the top of my head. If you have a machine
running the same OS, you should be able to flash archive it, seperate
out the configurations you don't want, and then use it on the upgrade.
It's not really what you're asking for, but it IS another opption if
you want to use Live Upgrade, and it turns out jumpstart won't work.
