Upgrade Zabbix from version 3.0 to 3.2

[aadesh]

Hello, I am trying to upgrade the Zabbix version 3.0 to 3.2 but after upgrading it it shows that error " The frontend does not match Zabbix database. Current database version (mandatory/optional): 3000000/3000000. Required mandatory version: 3020000. Contact your system administrator." when I was tried to access the dashboard.

I also tried to install a new Zabbix server 3.2 and restored the mysql database of Zabbix server 3.0 but it still showing the same error. I checked the logs to see the database up gradation process, It will failed after 7%.

Thank you

If you are using systemd, it may take time to upgrade the database and processing may be interrupted.

If you have a database backup at 3.0, please recover the database from its backup.
And do not use systemctl when starting Zabbix 3.2's Zabbix server for the first time.
