I have some data being ingested via Logstash where a specific date field is stored as below in ES: "MyDate": "2018-01-17T10:11:59.982Z I would like to store this date in ES , as a date field in format as follows: "MyDate": "2018/01/17 10:11:59.982" Is it possible to do this, in a away that it will be recognized as a date field? ---

You can format that field accordingly in Logstash and define a [custom date format](https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-date-format.html) for that field in ElasticSearch. ---
