I'm thinking of upgrading my HP C3000 PA-RISC machine to 11i from 11.
Are there any 'gotchas' to be aware of. I know for Solaris I've never
upgraded and always done a fresh install to avoid any old baggage left
around, but I'm tempted to just do an upgrade.

The machine is only a home computer with very little on it, so in
principle backing up to tape and restoring data would not be that much
of a hassle, but if an upgrade is even less, I'll take that route.

There are no node-locked packages of any form on it - just free stuff.

We have upgraded our PR7400 from 11 to 11i. Our only gothcas were problems
with tape backup performance using an IBM tape driver. Other than that it
has been working fine.

I am in the process of designing a 11-> 11i migration, best bet so far,
get a new disk and install 11i on that clean. That way you can go back
and forth if needed. The real gotcha is that you need to make sure all
your apps will work, aint there yet :-(

11.00 to 11.11 was the smoothest update ever. However I'd recommend to
read the installation and upgrading guide, backup your system
(make_recovery), and build a installation depot with current
applications, OE, and patches. For huge machines, every reboot saved
is worth an extra coffee break.

Ulrich

Thanks for that. The machine has very little on it - gcc, acrobat reader
and a few freebies in /usr/local. That is about it. I'm still hunting
for an HP C compiler.

From what you and others say it is no big deal, so I'll do an upgrade.

The clean disk idea is nice, but I don't have such a disk. It's a home
machine, which rarely gets used apart from checking portability of
software, so I don't tend to want to spend too much money on it. As long
as gcc works that is all I really care about. If that don't work I'm up
the creak without a paddle, but there is nothing else on it that I can
not do without.


One might well argue there is no point in me upgrading. That is probably
a very valid point, but given I got the CDs it seems worth doing.

Upgrade itself is really easy. But to start the upgrade you need to have
enough free space in the file systems / /stand /usr /opt /var and /tmp. So
if you have separate file systems and /stand is too small you have some
extra work.

When filesystems like /stand weer too small, we used
make_tape_recovery to backup the system, the boot that tape to
interactively restore with larger filesystem sizes. It's more
fool-proof than messing with single-user yourself BTW...
