OS upgrade from 11.11 to 11.23

[sen_ux]

Hi All,

I need to upgrade my HP-UX 11.11 to 11.23. Below are the details. Please suggest, how to proceed.

Model : 9000/800/rp3440#1
OS : HPUX11i-OE B.11.11.0612 HP-UX 11i Operating Environment Component
Existing Apps: Oracle 10gR2 , Appache, Tomcat etc.

Server has got 2 internal disks and are part of vg00. Oracle filesystems also reside on vg00 (Bad Design ).

Please help me plan for this upgrade and let me know if you need more info..

Thanks
Sen

Shalom Sen,

update-ux is very unreliable doing major OS upgrades.

Best bet is to do a cold install and then re-install all applications.

I'd also recommend 11.31 instead of 11.23

The end of life date on 11.11 and 11.23 is the same. You don't get much by the path you have chosen.

Due to your design concerns, I would take care of moving the oracle file systems out of vg00 before I started.

If we go for a cold install, how do we maintain the OS configuration that we have in 11.11 version like Kernel parameter configuration, network config, services and processes, security configuration????

correct me if i wrong, update-ux helps us to maintain these configuration when upgrading O.S from lower version to higher one?

VA.

As a sysadmin, you should know which files have this info and "port" that info to your new system, with the appropriate changes.

Hi,

Agree too, Update-ux keeps configuration of the previous os and should be helpful here,

- Please make sure have good ignite backup  before proceeding,

- create update-ux depot for 11.23 in a network depot that is reachable.

- test it, abnd install using update-ux.  It is pretty straight forward and works well.

Sample commands: example:

- Install update-ux software from NETWORK server depot:
[ Update-UX             B.11.23.0712.069 HP-UX Update-UX ]

:#  swinstall  -s  ServerA::/IDEPOT/depot_11.23  Update-UX  

-Run actual update-ux to update 11.11 to 11.23 

# update-ux -s ServerA:/IDEPOT/depot_11.23 HPUX11i-OE-MC T1335BC

[ Remember you can specify any additional bundle after the OE , in this example, vpar software after the OS OE mentioned]

- Monitor the logs, with the progress.

For direct going for 11.31 , you cant go 11.11 to 11.31,    you have to go through 11.11 --> 11.23 -->. 11.31  path., with update-ux install.

Good luck,
