I currently have this installed: Server version: 5.5.43-0ubuntu0.14.04.1-log (Ubuntu)
I would like to update to the latest stable MySQL release. Could someone point me to a good tutorial or write the command I need to execute in the shell?
Also is there any important thing I should know about before I do this upgrade? I have several sites on this server and I don't want their databases getting corrupted by accident during the upgrade.
