Hi All,

Is it possible to retain the data from previous version of elasticsearch when I am upgrading to latest version.  
I was starting to work with GRAPH which gives me error for the older version of elasticsearch.  
My current version -elasticsearch 2.1.0

Regards,  
Prateek Divya

Yes, you can upgrade without data loss.  
See [https://www.elastic.co/guide/en/elasticsearch/guide/current/\_rolling\_restarts.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/_rolling_restarts.html)
