Upgrading from 4.1.1 to 5.3.2

Hi, I installed Grafana 4.1.1 on an RPi a long time ago and it is a great piece of s/w and is working well. However I see that it is now on 5.3.2 and I feel I should upgrade as no doubt there are lots of new goodies for me to play with. I had a look through some of the release notes but it isn’t clear to me whether I can just install 5.3.2 over the top of 4.1.1 and expect my existing dashboards to keep going or whether there have been some breaking changes (as might be inferred from the change from 4.x to 5.x).
Could someone point me in the right direction please?

It’s ok, I found http://docs.grafana.org/installation/upgrading/ so I am good to go now I think.
