How to copy some of the data from one MongoDB to another

Question

I have an existing MongoDB dump and I would like to cherry pick some of the data to a clean DB.

Is dumping a single collection and restoring them (mongodump & mongorestore) the way to do this?

Answer 1

You can to this by using the --filter '<JSON>' option on mongorestore.

That's like the first argument of db.find().

If you just want to filter by collection --collection <collection>
