I'm using Elastic Stack in version 6.3 (Elasticsearch - Logstash - Kibana - Beats) and I plan to upgrade to 7.2.
I followed the webinar presenting the best practices to upgrade Elastic Stack. I think I will execute this process :
Upgrade Elasticsearch and Kibana from 6.3 to 6.8 in order to use Upgrade Assistant.
Upgrade Elasticsearch and Kibana from 6.8 to 7.2.
Upgrade Logstash and Beats from 6.3 to 7.2.
I have two questions :
Do you think that my process is correct?
Within the Logstash documentation I read that it was required to upgrade Logstash from 6.3 to 6.7 before upgrade to 7.2 because the
_typesetting changed from
_doc. I don't understand why is this step mandatory, could you explain me?
Thanks in advance for your help.
