I have a nagios item which is a switch that I have changed the IP on in 
hosts.cfg but the old host keeps getting pinged insted.

Is hosts.cfg the correct file to edit to update an item when the IP has 
changed.

Also Nagios is installed on Red Hat and I would like to migrate it to 
Debian, I have tried to copy the required files but the versions in Nagios 
are too different to accept the nagios.cfg file, what would be the best way 
to migrate a Nagios install from Red Hat to Debian?
