Nagios Support Forum

Hi ,

I an using Nagios Core 4.0.8, and I am having around 6000 machines monitoring on this server. Without any impact how I will upgrade to the latest one?

I have some customisation on command.cfg file, contact.cfg and contactgroup.cfg etc...


Will it overwrite any existing files ?

Hi,

The upgrade process will not overwrite the configs, but be sure to back up everything up before upgrading.

How did you install Nagios Core? If it was from source, I would recommend following the guide below
