Hello,
I'm trying to basically follow the instructions here Dec 15th, 2017: [EN][Elasticsearch] Going from multiple types to one type with the Reindex API except that I'm using "_doc" instead of "doc" as that seems to be preferred now. I'm using a template with dynamic mapping for both the source and dest indices. When I run the reindex I get an error like "Field [field] misses required parameter [scaling_factor]". "scaling_factor" is required for both 5.x and 6.x indices so I don't know how the docs could be in the 5.x index or how only a couple of the nearly 1000 documents processed could have an error.
Any thoughts?
