Nagios Core Config Migration

[Pponze]

We're running Nagios Core v3.2.0 on a stand alone desktop which is working great. Now we're tasked to make a new Nagios Core server running as a VM. I downloaded the latest OVA 5.2.9-64bit. Can we migrate the configuration from the old to the latest version? Any known issues?

Thanks,

Paolo

The OVA that you downloaded is for Nagios XI, are you looking for XI or for Core? There are no pre-built images for Nagios Core unless you purchase it:

Here is the manual installation guide for Nagios Core:

If you are looking to move to XI, here is the Core migration guide:

Thanks for pointing that out, ssax. We're staying with Core and want to migrate to a new vm with Core 4.1.1. Any issues migrating the configuration files to a server on a different IP subnet? Thinking about building the new VM at a different site.

Will Core run on Ubuntu 15.10?

It sure will. Take a look at this guide - https://support.nagios.com/kb/article.php?id=97

Thanks. Ended up installing it on CentOS instead and have Core 4.1.1 running. Now I'm just looking for the config migration steps from 3.2.1 -> 4.1.1.

You should be able to copy them straight across and run a verify.

Code: Select all

/usr/local/nagios/bin/nagios -vvv /usr/local/nagios/etc/nagios.cfg

If the verify fails go and fix what it's complaining about.
