Nagios Support Forum

Hello

It appears possible to upgrade CentOS 6 to 7. Is this something that would break the Nagios XI installation? it would be nice if we knew this was supported.

Admittedly - to the best of my knowledge we're inexperienced in the matter.

I would probably suggest 'don't' do it and expect it to work. Our fullinstall does a lot of `if 6 elif 7`. The only thing I can vouch for today is that fullinstall on 7 works *pretty well*. We're still running into bugs here and there and the devs are quick to squish them. I would recommend backup/restore.

Doing the upgrade is trivial enough we can try on our test systems here for you if you'd like, however based upon my knowledge of the install script I'd fully expect there to be issues, probably many that I wouldn't come across since my test environment stands no chance of testing all of the functionality you're implementing.

Well, I was absolutely not planning on doing this anytime soon, but as CentOS 6.6 is eol November 30th, 2020, it would be nice if I could somehow do an upgrade to 7 in 2020.

If you can wait till then.... we'll probably have an upgrade path for you. Maybe by then you'll be running nagi-OS.

The biggest difference between the versions are the init system (systemd) and sql db (mariadb). Upgrading the system may have consequences for both of these, in the very least you will have to recompile all nagios XI bins related to the databases and you may need to mess about with the init scripts. A backup and restore is better (but still requires rebuilding ndo for the new mariadb libs).

Ok... Never mind. i'll come back to this in three years.. Please close
