Nagios Support Forum

I am migrating to a new server and performing a new install

Does this mean I have to configure everything all over again

Thanks for all your replies
I will look into all the suggestions
The issue is that we have Nagios Core and would like to upgrade this and not need to get Nagios Log which requires additional license

I have a task here we have a very old Nagios Core 3.2.3
we want to migrate to the latest Nagios core 4.x or even 5
on a virtual  Unix (redhat or Ubuntu)
This is going to be a new installation 
Is there any Migration tool to migrate all the files from the old to the new without any hiccup

hello
I want to know how Nagios Core can check if a log files is been updated or if its stops updating it should create an alert or sent a notification
