Hi, wifi75!

I just tested upgrade from 3.0.16 to 3.4.8 on CentOS 7.4 with MySQL as the database engine and SELinux enabled.

Take a look on these notes:

https://github.com/catonrug/zabbix-scripts/blob/master/upgrade-from-3.0-to-3.4-centos7-simplified.sh

Keep us informed how it goes
and remember to backup database or operating system by itself.
