Nagios v4 Upgrade Considerations
================================
This applies if you are upgrading from Nagios v2 or v3.
The Nagios v2 or v3 nagios.cfg is will not pass a Nagios v4 syntax check without modification. Also note that Nagios Core v4 has more strict host/service definition requirements.
The following attributes from Nagios v2 or v3 are incompatible with Nagios v4 and will generate an error.
use_embedded_perl_implicitly
sleep_time
p1_file
external_command_buffer_slots
enable_embedded_perl
command_check_interval
In order to force a Nagios v2 or v3 nagios.cfg file to run with Nagios v4 simply commment out these nagios.cfg lines.
The included script UpgradeToVersion4.sh will do this automatically for the file
/etc/nagios/nagios.cfg (the standard location for the nagios.cfg file)
This is a work-around and you should consider implementing the new nagios.cfg file.
