Auto Increment id for collection - Mongo

i want to add a id auto increment in Mongo like MySQL does.

I use the Mongoose Auto Increment Library and this works fine.

My problem is that I was not able to place that ID in the documents already created after implementing the library

In this I created a Query to made this before add that library

db.clients.updateMany({},{$set:{id:0}})

This add the 'id' field in all documents whit 0 as value.

Now I want to add the correct id to all documents, but this query add the same id to all documents.

for(var i=0; i<db.clients.count(); i++){
    db.clients.update({},{$set:{id:i}})
}

Someone have any idea what I can do?

I appreciate any response!
