Any reason you don't go all the way to 11.31 by cold install?

Hello Prajul, 

To upgrade 11.11 to 11.23  you have to decide what method of upgrade you are planning for,  update-ux or Cold Install Method. 


Depending on your system need and downtime planning, you can choose either methods.

- For cold install you have to freshly install all other application , 3rd party software, binaries etc. Also you have to create users, groups, configuration files , settings .


- For update-ux install , you have to less touch on the configuraion and software installation part & can be safe, if having less downtime window. 


- Also you need to check pre-reqisites & compatibility options for all the componenets attached to the server, along with server firmware compatibility & support matrix. Check Storage support matrix. To check vg00 filesystem free space if using update-ux . 



check out the below document: in gogle for upgrade tasks, :  
 - HP-UX 11i v3 Installation and Update Guide   

- update-ux(1M)  


- Also make sure all the backups are in place before starting: 


A: Ignite Tape Backup / Ignite Net backup.

B: Configuration Files Backup.

C: tar backup of important vg00 FS ( Like /etc /opt /home ..) 

D: if database running: have cold backup of database.

F; All OS nonVG00 & Fs backup. 


- if you describe your scenario ,  more info can be provided.
