Hello guys , i am indexing **existing data** of mongodb to elasticsearch. using **mongoosastic** plugin by .synchronize() method which is taking lot of time.  
Are there any ways that i could index all **existing data(which contains around 1-2 millions documents)** from mongodb to elastic .Please help me out.
