You can upgrade your Elasticsearch version from 0.90.x to 1.x in the following way
Cluster restart upgrade process
Before upgrading Elasticsearch, it is a good idea to consult the breaking changes docs.
As per Elasticsearch Documentation before performing an upgrade, it’s a good idea to back up the data on your system.
