What to consider when upgrading ELK from 6.8.9 to latest stable version? I understand that I should be doing a rolling upgrade from 6.8.9 to 7.16.3 and from 7.16.3 to 8.x How can I reindex the existing indices? I also use custom input filters. Will I be able to use them on latest 8.x version? ---

The upgrade assistant in Kibana is a great place to start! > **[Upgrade Assistant | Kibana Guide \[6.8\] | Elastic](https://www.elastic.co/guide/en/kibana/6.8/upgrade-assistant.html)** ---
