Upgrade OS to 64bit

[Veron_Le]

Hi all,

My customer are using HP-UX 32bit running on K-Class. Are there anyway to upgrade to 64bit?

Thanks for your help,
Trung

It depends upon the model; It needs to be at least a KX50 or above. A few of the K-boxs used the 32-bit PA-7200 processor (e.g. K220) but most used the 64-bit PA-8000. Those K-boxes which have a 64-bit processor can run 64-bit 11.x.

Run this command:
getconf HW_CPU_SUPPORT_BITS

If it reports 32/64 then your K-box can run either. Many K-boxes require a firmware upgrade before doinhg the OS upgrade.

Hi all,

Thanks for your info.
Do we need uninstall all 32bit Apps before upgrading? Or Can we uninstall them after upgrading?

Thanks,

Hi all,

Do I need uninstall MirrorDisk? Is it applicable for 64-bit?

You do not need to remove any application software, including Mirror/UX as part of the upgrade process.

See Procedure to Convert between 32-bit and 64-bit OS http://www.docs.hp.com/hpux/onlinedocs/B3782-90728/00/00/52-con.html

Step 4: /usr/sbin/swinstall \
-x logdetail=true \
-x autoreboot=true \
-x match_target=true \
-x reinstall=true -x reinstall_files=true \
-x os_name=HP-UX:64 -x os_release=B.11.00 \
-s /SD_CDROM

See all steps on this page. This is Step 4 which is done after the Operating System has been converted to 64 bit.

Hi

A list of K servers, which can run 64 bit:

Re upgrade: IMHO, installing from scratch is much better. Don't make trouble for yourself by such an upgrade.

Good luck.
