Re: from 11.11 to 11.23
You are correct in that a "cold install" is like a new OS installation. You are essentially wiping out whatever was on the disk and installing the OS as new.
>>Please share the steps to upgrade the OS versions in HP-unix
Have a look at the 11.23 documentation for upgrading the OS.
http://docs.hp.com/en/oshpux11iv2oe.html#Installing%20and%20Updating
The lastest installation and update manual is:

Re: from 11.11 to 11.23
The prefered method is to cold/new install the OS, add patches, cold/new install the application and mirgrate your data from the old system to the new. ( plus this method has the advantage of leaving the old environment around as a fall back incase of emergency)
Most application vendors (depends on application) do not recommend upgrades either as it typically would require an upgrade of the application software but the application is now in limbo due to the OS upgrade. but certainly check with their support as well.

Re: from 11.11 to 11.23
A cold install is a lot of work anyway, certainly if you have a lot of customizations (like we have). You will have to reconfigure everything again from scratch. Probably a few configuration files can b erestored from backup.
If you have to upgrade multiple systems (like we had), you could cold install the first one (it may take days to complete all site-specific post install configurations), and use an Ignite backup to install the other systems (takes a few hours). That saves you a lot of manual configuration work on all systems, and makes the one-time cold install with manual configuration worth te effort.
If you have only one system to upgrade, why not try update-ux as first option. If it works, fine, you saved yourself a lot of work. If it doesn't, you can still switch to cold install.
And beside the fact that many of my forum members say that upgrading is error prone and not recommended, I heard that update-ux has improved a lot lately and is not so bad anymore as in the past.
At the other hand, when you choose to cold install, you may as well go to 11.31 in one go. 11.23 is nearing it's end-of-life, just as 11.11 is. The lifetime of 11.31 is a lot longer.

Re: from 11.11 to 11.23
U can upgrade from 11.11 to 11.23 which is straight forward procedure but u should take all kinds of backup before this activity as precaution. After upgrading , all file system as well as evrything should be same as well.
