We have an existing Kibana 3 installation in production with a lot of data being gathered. I would like to install Kibana 4 to take advantage of some new features, but I don't want to break what we already have and I don't want to upgrade until all the people involved are ready. Can I install Kibana 4 and have both it and Kibana 3 running simultaneously on the same server? Or do I need to set up a new test box for this?
Thanks.
