I am currently going through the Elasticsearch deprecation logs to check what we may need to resolve prior to upgrading our ELK Stack from v6.0.0 where I have found the following but have no clue how to resolve.
[o.e.d.a.a.i.t.p.PutIndexTemplateRequest] Deprecated field [template] used, replaced by [index_patterns]
Deprecated field [inline] used, expected [source] instead
[_default_] mapping is deprecated since it is not useful anymore now that indexes cannot have more than one type
Fielddata access on the _uid field is deprecated, use _id instead
Looking at the fields _id is currently being used.
Index_patterns is displayed when doing GET _template
Inline is also not being used
We have not set a custom template in logstash it uses its default.
Can anyone shed any light?
