Hi,
In my ELK setup, I am getting mapping conflict. I had change my index name from unix-* to logstash-* . I have about 3 TB of data in my setup and I can't loss them. So I did not delete the old index, this gave me an error of
courier fetch: shards failed
So I rename my index to the original name and it is working fine now.
How can I remove the mapping conflict without deleting my old index ?
