Upgrading 10.20 to 11i

[Bryan_6]

I've heard that upgrading is usually not the path sys-admins would take (including myself)... But I was curious if anyone has successfully upgraded (not cold install) a 10.20 box to 11i. If so, how did it go? Any gotchas?

I know I'm not answering your question but just want to point out that ..

will help you decide (cold install vs update). Most people would recommend a cold install.

I have never had a smooth upgrade so for production servers i have to say that a cold install is the best way to go.

Hi,

See this check list for upgradation/cold install (10.20 TO 11.x):

Bryan,

Unless you have a 10.20 that is very clean, upgrading to 11.x is unwise, and even with a clean 10.20 system, "upgrading" isn't guaranteed. The horror stories are plenty. If you have a few dozen hours to waste, then you can attempt the "upgrade", but if you want to save yourself a lot of time, do a cold install. A cold install ensures that your system doesn't have any dangling 10.20 gotcha's. You can do a cold install in less than two hours, whereas an "upgrade" could easily cost you a day or two. I have been found that cold installs are better and faster, and this is something I have held on to since the mid 80's.

Thanks for the input all. I share the same feelings, but thought it would be interesting to ask to group.

Bryan,

Definitely go cold-install.

Biggest headache I had was LV size requirements. Most older 10.2 0s don't have large enough / /usr or /var LVs & it's a pain expanding them IF you have enough space left in vg00.

I concur with Harry.
I had done it once on a system where I loaded 10.2 fresh and then upgraded 11.0 (was given the OS soon after the install and didn't know any better) It's a nightmare if your system has actually seen work. I only cold install now.
Good luck,
Kel

Hi,

This subject comes up periodically and I answer
the question in the same way. If you can do a
cold install. I've tried to do this at least 20
times and always get the same result ... failure.
There a few headaches with this:

firmware
vg00 not being large enough
kernel building during the installation

my 2 cents worth

Michael, I wish HP would just remove the option. It's ignorant for HP to have this kind of false hope for people that don't know better. It's like Smith & Wessen having a gun where the bullet comes out the wrong side of the barrel (back at ya).

Michael, I match your 2cents, and raise you 2 more cents!

Hi Harry,

Totally agree...

It's like the ole west... everyday there's a hangin and a shootin' and in the saloon there's gamblin' even if it's raising ya 4 cents it don't get ya very far!

Cheers
Michael
