Unix 11 32bit to 64 bit Upgrade

[Neil Hand]

System has been previously upgraded from 10.20 to 11.00 32bit, Now want to upgrade to 64bit mode. Has failed twice,with corrupted filesystem. When swlist is done no O/P showing
HPUXEng32RT B.11.00 English HP-UX 32-bit,also
March 2001 general release patch bundle currently installed,and using Dec 2000 Update CD for upgrade,but using allow_downdate=true option when doing upgrade. Is this causing problem,also how much space do I need for upgrade?

Hello Neil,

Perhaps it's time to look at your problem from a different perspective. Wouldn't it be much easier just to reinstall the OS instead of upgrading? I've seen a lot of problems arising from failed upgrades. Normally, it takes far less time to reinstall.

Hi Neil:

I would urge you to take an Ignite recovery backup and do a cold-install of the 64-bit OS. This best guarantees a clean, error-free result.

Thanks for replying,may need to look at this option,but for the moment, would rather stick with the upgrade route,

Whenever we've done this we've always done a clean install and put the data back on...

(This also gives you a chance to clean up a lot of the rubbish you get from old releases etc.)

Back it up - make_tape_recovery vg00 (ignite)
and then do a clean install of 64 bit.

Far less hassle over and done in about an hour.
Then put you config files back - passwd -hosts- group -etc-etc.

Restore your data and then test.

If you do a search on the forum then the feeling is to do a fresh install rather than an upgrade.

Hi Neil,

what is your system model and firmware level ?.

I would also urge that you do a fresh install rather than try to upgrade the system. Doing an upgrade would, you'd have to deal with cleaning up all the 32-bit driver and replacing them with 64-bit once...not to mention all the patches that will probably need to be re-installed (remember most patches have both 32-bit and 64-bit pieces). Rather then try to deal with this mess, it would be much easier to re-install the OS on the machine.

Hi,

Looking at the document detailing the upgrade procedure, i would suggest like everybody else to go for a fresh install.
I have always done it that way and it is worth
the xtra effort , since it is one-time.
