@mtripodi, Good idea, let me know how it goes. After you copy the folder over to the new server run the following command:
Code: Select all
service nagios restart

Then run the following command to check for any errors:
Code: Select all
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Ok thanks, I was able to successfully copy all my folders containing existing config files into the location: /usr/local/nagios/etc/objects/

I noticed we also have a bunch of plugins which are likely associated with service checks we have setup. Located in:
/usr/lib/nagios/plugins/ and /usr/local/lib/nagios-plugins/ .

Should I be copying all these plugins over as well? If so, to which directory on the new Nagios server?

@mtripodi, Hmm. Did you install any special plugins or are these just the standard core plugins? Try to import the checks without plugins fist and see if they start erroring out. Then please upload the failing service checks definitions here.
