==Updating from 2.12 to 3.05==
I was able to successfully update a simple Nagios installation using the following commands:
<nowiki># save the existing nagios config
cd /etc
tar -cvf nagios.tar nagios/*
# remove nagios 2.12 and install nagios 3.05
rpm --nodeps -e nagios
yum --enablerepo=dag install nagios
# restore the nagios 2.12 config folder
cd /etc
mv nagios nagios.org
tar xvf nagios.tar
# comment out the only nagios 2.12 directive that nagios 3.05 complained about
cd /etc/nagios
mv nagios.cfg nagios.cfg.org
sed s/"check_result_buffer_slots"/"# check_result_buffer_slots"/ nagios.cfg.org > nagios.cfg
# restart nagios and nagiosgrapher
service nagiosgrapher restart
service nagios restart</nowiki>
