I'm currently mantain ELK platform all working ES2.4.1  
in fact , kibana 4.6 is using a ES2.4.1 Tribe connected to several clusters all in ES2.4.1.  
I think add a ES6x cross cluster search connected to the same clusters ES2.4.1 and then a new kibana instance connected to this new ES6 cross cluster search.  
Do you know if ES6x cross cluster is fully compatible to connect ES2.4.1???  
Could I use kibana6.x connected to ES6x cross cluster??

Thanks

As per [the documentation](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/modules-cross-cluster-search.html) Cross Cluster Search requires Elasticsearch 5.5 or later, so version 2.4.1 will not work.
