My company is a ReadonlyREST Enterprise subscriber.
From what I saw in the documentation there have been some major changes in ROR from v7.8 onwards.
I want to ask for the procedure on how to upgrade from v7.8 to v7.12 for Elasticsearch & Kibana.
We have 1 production cluster running v7.8 on CentOS 7. I want to upgrade it to v7.12, but I am afraid of encountering some unexpected error during the upgrade. We are using the Kibana App for the ROR configuration.
What is the recommended approach for upgrading ?
