I am currently working on moving physical zabbix server 4.2 version(that is running on Centos 7) to a Zabbix 6.2 ( that is running on a Ubuntu 20.04 (focal)). The 4.2 version is using mariadb and the 6.2 version is using mysql. The size of the old server is above 2 GB. Can someone help with the steps...
