Hi all,
Our current Zabbix deployment is running Ubuntu 14.04 LTS and Zabbix 3.4.14, we're looking to upgrade to Ubuntu 18.04 LTS and Zabbix 4.0.x.
Here is our "Status of Zabbix", as you'll see it's quite busy:
As part of the upgrade we are going to split the MySQL DB (80GB) out to a dedicated VM, with the Zabbix Server and Dashboard/Apache on another VM. This will simplify our DR in the future.
My question is: Are there any clever strategies for upgrading the Zabbix database from v3 to v4 that don't involve hours of downtime and loss of data/alerting while the database upgrades?
We rely heavily on Zabbix the downtime would be painful.
Thanks,
S
