Feels like homework but...

(assumes nagios versions are the same and using a source-installed  
nagios)
- Configure the webservers the same (The nagios documentation should  
help here).
- Install nagios on the new machine
- Install nagios plugins on the new machine (including any special  
ones you've installed or created)
- Install any nagios addons you use on the new machine
- Move dynamic data from current nagios to the new machine
		# stop nagios on current machine
		# tar up current etc and var directories
		# restart nagios
		# copy data tar file over to the new machine
		# log in to the new machine
		# extract the data to the new install of nagios
		# verify nagios configuration
		/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
		# [start nagios if all looks well].

If you're using NSCA or any other passive checks, you should know what  
to do there.
