Thanks man!!!
Hi,
This works fine, but my requirement is to get the indexes for all the existing databases from above script i have to manually type the database name and it is hard if there are multiple databases.
It would be great if i get indexes of all the databases along with use database; so that i copy the same on other server to create schema and indexes.
Thanks.

Hi,
Thanks for the script. I have tried using it, come across some issue that collation settings shows as [object ]. Please update..
db.Collection_Collation.ensureIndex({ "_id": 1},{name: "id",collation: [object BSON]})
db.Collection_Collation.ensureInde({ "_fts": "text", "_ftsx": 1},{name: "FullTextSearch",weights: [object BSON],default_language: "english",language_override: "language",textIndexVersion: 3})
