I'm currently using Kibana 3, and would like to upgrade to Kibana 4. However, I would like to keep Kibana 3 around until I have my dashboards in Kibana 4 configured. Can the two be run side-by-side without interfering with one another? 

I know that Kibana stores its settings in the attached Elasticsearch database, so I am worried that Kibana 4 might overwrite settings in my Kibana 3 instance.
