Hi,
I have been trying to upgrade the ELasticsearch version from 7.1.1 to 7.8.0 and unfortunately it has broke our Kibana. I had a good reference on breaking changes and new upgrades for each version with the help of documentation in Elastic.co website for each version.
I am interested to know whether we have any detailed documentation on the changes to be made in configurations and other .yml files to have successful upgrade. I suppose this help a lot of developers around the globe to save enough amount of time.
Thanks
