I would like to upgrade my Matomo host, from Ubuntu 14.04 to 18.04. Will I break Matomo if I attempt a standard distribution upgrade? How should I answer the questions about using default or existing configuration files that are asked during the upgrade (like for php, etc.)?
I originally installed as Piwik, then updated to Matomo. If I rebuild Matomo from the ground up on Ubuntu 18.04, I’m afraid I will need to change the info that gets attached to every web page which enables analytics collection (since it now would mention Matomo rather than Piwik) which I don’t know how to do, as I’m not really a web developer. We’re a non-profit and don’t currently have a developer available.
