I copied the pipeline from our old stack (7.17) and pasted it to our new ELK stack (8.6).
I copied the mapping of one of my indices in the old stack and created a new index in my new kibana with that mapping.
In my new kibana, I went to index management and I saw the number of documents increasing under my index. I created a data view ( index pattern), went to discover, and selected my new data view to find out is empty.
What I am doing wrong?
