Update zabbix from 3.4 to 5.0.1

[redelek]

Good morning,
I upgraded from 3.4 to 5.0.1 from Zabbix, everything went fine as per the instructions.

https://www.zabbix.com/documentation/current/manual/installation/upgrade/packages/rhel_centos

After updating, I get a message on the page

Database error
The frontend does not match Zabbix database. Current database version (mandatory / optional): 5000000/5000001. Required mandatory version: 3040000. Contact your system administrator.

The server logs show that the database has been updated. How can I solve this problem?

It's the web-based "frontend" that's complaining, which means you still have the 3.4 frontend installed. You also need to upgrade the Zabbix web interface to the same package versions.

Depending on which version of RHEL or CentOS you're on, there may be some special steps required, because of the updated PHP version requirements for the web interface. That's covered in the URL you referenced.

I did the update

yum upgrade zabbix-server-mysql zabbix-web-mysql zabbix-agent

but as you can see some packages remain old

zabbix-mysql-web-3.4.15-1.el7.noarch
zabbix-release-5.0-1.el7.noarch
zabbix-mysql-server-5.0.2-1.el7.x86_64
zabbix-get-5.0.2-1.el7.x86_64
zabbix-web-3.4.15-1.el7.noarch
zabbix-agent-5.0.2-1.el7.x86_64

If I run update zabbix-web
everything is up to date

I have successfully uninstalled zabbix-web and zabbix-web-mysql and installed new versions.
Everything works. Thank you for your help
