HPUX upgrade

[bagek]

Hi, thanks for all the great responces. If update up is not the best way then what is?

[Dan Bolton]

A "Cold-Install" is the recommended method.

A Cold-Install follows these basic steps:
1) Back up all config files you want to restore (/etc, /etc/opt, etc.)
2) Make a recovery image (in case of problems)
3) Verify you have media and codewords for your apps
4) Do a fresh install of the new OS version
5) Restore the desired config files
6) Re-install your apps

See the HP-UX 11i v2 Installation and Update Guide for complete details.

You should probably do a cold install and go to 11.31 if your hardware will support it.
After you've done your basic prep work (create an ignite tape, comlete backup, etc), pull the old drives out and upgrade them if possible to larger drives. Keep track of the order of the drives that you've pulled. If you have any issues you can not resolve or need to be back on-line quick, simply reinstall the old drives and reboot.
If everything goes well, restore your data, apps, and scripts from backups.

Good Luck.

Bagek,

Unless there are specific reasons to *NOT* go to 11.31, I would certainly do that.

But ... what hardware do you have exaclty ? Except for the 2 mirrored 36GB disks, is there more available on a SAN or external storage unit ?

How much memory do you have ?

And ... depending on what applications you are running, and what you currently pay for support, you may be better of with new hardware ...
