We're planning to upgrade zabbix2.2 to 4.0.
The procedures is as follows;
1, upgrading zabbix 3.4 to 4.0 with RPM packages
2, then import zabbix configurations from 2.2 to 4.0(upgraded from 3.4, in procedure 1)
When importing and exporting zabbix configurations from 2.2 to 4.0 in this way, is there any important notice and guides?
and do you have any similar case?
