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.
