I made a mistake by trying to upgrade my elasticsearch version from 6.3.2 to 7.2.0. I launched my container with the new version but I realized that kibana does not work anymore. So I decided to downgrade elasticsearch to 6.3.2 to get a quick fix but it still not working. I got the following error…

Unwanted Upgrade ElasticSearch version

You can't downgrade, it is forbidden from 6.8
Maybe you should return to 7.2 and fix kibana?

Mistakenly upgraded without reindex or assistant. Now I cannot fix it
