Upgrade 3.0 to 4.4

[klarter]

The modules have changed! Is zabbix-web-mysql somehow equivalent to phpfrontend?
Could someone map out the upgrade process for me?

Yes, the fronted is dependant to the database you're using, so, try to follow this guide lines:

• Base: https://www.zabbix.com/documentation...lation/upgrade
  • Centos: https://www.zabbix.com/documentation...es/rhel_centos
  • Debian: https://www.zabbix.com/documentation.../debian_ubuntu

That is what I did, thanks. When I try to start the zabbix-server I get an error "zabbix-server.service: Failed at step EXEC spawning /usr/sbin/zabbix_server. No such file"
I do have a file "/usr/sbin/zabbix_server_mysql" and an empty file "/usr.sbin/zabbix_server"

I now have the server starting but the database upgrade fails:
[Z3005] query failed: [1091] Can't DROP FOREIGN KEY "c_sessions_1
