[Sunit Shukla]

Hi Guys !

Does anybody has the procedure to upgrade hp-ux 10.20 to 11.0 for couple of machines connected in network. Your suggestion will be highly appreciated. Thanks.

A cold install is generally recommended. Use vgexport -p -s -m mapname to make map files of your non-vg00 volume groups, save off config files, etc., do the cold install, vgimport, restore configs.

It's strongly recommended that you use a cold install instead of an upgrade. But to answer your question, this guide will be useful (TKB# KBAN00000716):

Hi Sunit,

I second Pete though you can use "swgettools" to upgrade 10.20 to 11.0. It is tedious. I would suggest you to plan well.

1. Note down all the softwares and make sure you have depots for each of them for 11.0
2. Take a configuration snapshot of 10.20 and save it on another system. This includes but not limited to map files with different options of vgexport, fstab, passwd, group, netconf, hosts, resolv.conf, cronjobs, system, swapinfo, lvmtab, bdf, ioscan, lanscan, services, swlist etc., and others that you can think of.
3. Take an ignite image.
4. If possible install 11.00 on a different set of disks.

Why wouldn't you consider going to 11i directly?.

Unless you have exactly 1 LAN card (the built-in one) and no special networking software like ATM, ISDN, X.25, etc, don't even consider an upgrade. Backup your data files and whatever else will run without change on 11.0 (you'll need new versions of many applications to run on 11.0). Then cold-install 11.0, add *all* the HWe and QPK patches from your SupportPlus CD (or download it from www.software.hp.com) and then add you applications and data files.

We have done a 10.20 to 11.00 with a cold install, I've only done it once and it seemed quite scary at the time. It was a while ago now.

I'm just replying to let you know it can be done, even by me (well with help).

There was a good deal of vgexporting and copying data (using cpio -pdmu I seem to remember) from one server to another.

Good Luck.

I also seem to remember there's a little book on it. Part Number 5971-0642 which probably comes with the OS disks.
