Upgrading from 3.4.8 to 4.4.4 failed due to missing db table

[dumkaz]

Hi

I am upgrading zabbix-server from version 3.4.8 to version 4.4.4 via compiling binaries from the source. I am dumping database from production zabbix setup, then i install the same zabbix version
on stage, and restore the database.
Finally i start upgrading process
Zabbix-4.4.4 configured and compiled successfully, but when starting new 4.4.4 binary i get the following error message from zabbix_server.log

Searching in google how to modify db schema/add table did not bring any reasonable results about this specific table.
Please advise

I have found the issue: I used database dump that did not include many tables in it. Have to fix my mysqldump script
