Upgrading - Compatibility Elasticsearch 2.x, mappings

Elastic Stack Elasticsearch
1

Hi,

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?

Thanks,

Luca

ES 2.0 only support KB 4.2.

And yes, it will reject document with those fields.
