I am currently running version 3.1.1 of Grafana and everything works very well.
I would like to upgrade to the latest version with minimum downtime. But I am worried that I will miss something up along the way.
What do I have to keep in mind when upgrading directly to latest version? and what files/configurations do I have to backup in case I needed to revert back ?
Also, is it enough to just run
$ sudo yum install https://grafanarel.s3.amazonaws.com/builds/grafana-4.1.2-1486989747.x86_64.rpm in order to update the existing package ?
