Downgrade Kibana 6.4.1.1 -> 6.4.0.1

[KindTomato (Tomato)]

Hey, I had an issue with creating new Indexes on Kibana 6.4.0.1 - on Dev environemnt i upgraded logstash and elasticsearch to 6.4.1.1 (kibana stayed 6.4.0.1) and it worked - so I did the same on prod - but unfourtantely upgraded Kibana aswell to 6.4.1.1 - now I have to downgrade it to 6.4.0.1; is it possible and if yes then how ?

There's no 6.4.1.1 or 6.4.0.1, only 6.4.0 and 6.4.1. Can you clarify which versions you mean?

Hey, well the version are same but without the .1 at the end ( 6.4.1 and 6.4.0 );

however the issue is already resolved - it was related to default index on kibana was empty and in read-only mode;

steps i took:
On Kibana-> Dev Tools ran:
PUT /.kibana/_settings

{

"index.blocks.read_only_allow_delete": null

}

then on server ran curl to get kibana setings:
curl -XGET http://localhost:9200/.kibana/doc/_search?q=type:config

and in there I found UUID for the default index

which I have putted with curl post:
curl -X POST -H "Content-Type: application/json" -H "kbn-xsrf: true" -d '{"value":""}' http://localhost:5601/api/kibana/settings/defaultIndex
