I would like to update my elasticserach to the latest version, but have a few questions.
Can I still use Kibana 3.x (we use 3 and 4 in parallel at the moment, but more 3)
or do I HAVE to use Kibana 4?
I also currently have some mapping issues to take care of. What would happen if I delete all indices with issues, start ES 2.0 and then try to index fields with dots in the name? Will ES just refuse to index them?
