Hello @Sankar,

Here are the instructions for upgrading Nagios Core. You'll want to make appropriate backups of your configurations and/or take a VM snapshot so you can roll back easily.

Hello Sankar,

I'm not familiar with that directory structure. Typically, everything will be found in the /usr/local/nagios folder. If you just want to backup the object configurations, those are found in /usr/local/nagios/etc folder.
