Hi All, I'm planning to upgrade my ELK stack in production from 5.4. to 6.6. I need your help for best practice and action items to achieve this goal. Below are the details - **ES (5.4.3)** - 20 nodes cluster, Data size = 16 TB approx **Logstash (2.2.4)** **Kibana (5.4.3)** **Logstash-forwarder (0.4.0)** I'll upgrade to 5.6 first then to 6. Also I would use filebeat in place of logstash-forwarder. Could you please help to share the steps what I need to do first? Thanks in Advance. ---

Was the [upgrade documentation](https://www.elastic.co/guide/en/elastic-stack/6.0/upgrading-elastic-stack.html) insufficient for your needs? ---
