Migrating NBU environment from Solaris to Linux
Updated: 25 May 2010 | 6 comments
This issue has been solved. See solution.
Our "gifted" IT top-managers are about to launch the process of migration of some of our IT systems from Solaris to Linux in order to reduce the TCO. It sound silly to me but there is nothing I can do about it. So my questions is if anybody of you out there have expirienced such a pain and what are major issues of such a migration in terms of NetBackup environment. Currently we are running NBU 6.0 MP6.

I haven't done the move myself, but I hear that moving from Solaris to Linux shouldn't be an issue if you keep the servername and all that the same.
The problem starts when you start changing server names as the catalog is dependant on that information.
If you do decide to move servers, run the consistancy check on the DB before hand.
In theory, it is from one UNIX-like OS to another so hopefully there should not be major issues. The one I could think of is "endianness" (i. e. byte order compatibility issue in integer numbers with different CPU types) - not sure if you would run into this or not.
However, Tech Support does not help with cross-platform migration issues - this can only be done by consulting:

Well, thank you very much for this weblink.
Make sure the distro your going to is fully supported for the options you want.

I was inches away from making my new master RHEL5 until i saw that there was some options we needed that were not supported/compatible.
Out of curiousity, what distro are you going to?
Let us know how it goes. The endian conversion is something that might need to be done on the database files.
Matt S - what version of NB are you on? We were looking at migrating from Windows 2003 to RHES 5.2 eventually and I'm curious what is not supported for 5.2 master.
Well, in our case, we want to utilize BMR.
If you go look thru all of the compatibility docs found here you'll see what im talking about. Just a few options that havent been certified for RHEL5 yet.
Just a few small things i know but i also dont like going to the latest and greatest if the previous OS version works fine. I tend to find upgrading to new stuff starting a chain reaction of updates to other software/hardware that usually ends in a mess. Plus I just dont gain any significant benefits from version 5.
ALTHOUGH, if we ever completley move away from tape ,which may be this year, i would like to look into ext4.
Would you like to reply?
