Optimizing Indices

Elastic Stack Elasticsearch
1

I'm trying to do some index optimization by reducing the amount of replicas after an index really shouldn't be written to anymore. Following this link.
https://www.elastic.co/guide/en/elasticsearch/guide/current/retiring-data.html

my curl statement looks like below, going after a distinct index called "logstash-syslog-2016.09.20"

I execute the following statement:

curl -XPOST 'rfdesmstr:9200/logstash-syslog-2016.09.20/_settings' -d '{ "number_of_replicas": 0 }'

I get this in return

{"error":{"root_cause":[{"type":"invalid_type_name_exception","reason":"Document mapping type name can't start with ''"}],"type":"invalid_type_name_exception","reason":"Document mapping type name can't start with ''"},"status":400}

Tried with sense as well and get the same result. Any ideas as to what I'm doing wrong?
Thanks!

curl -XPUT localhost:9200/INDEXNAME/_settings -d '{ "index" : { "number_of_replicas" : 0 } }'

If it will be something you do regularly, Curator has a Replicas action, as well as forceMerge and many others.
