How do you rename a MongoDB database?

Question

There\'s a typo in my MongoDB database name and I\'m looking to rename the database.

I can copy and delete like so...

db.copyDatabase(\'old_name\', \

In the case you put all your data in the admin database (you shouldn't), you'll notice db.copyDatabase() won't work because your user requires a lot of privileges you probably don't want to give it. Here is a script to copy the database manually:

use old_db
db.getCollectionNames().forEach(function(collName) {
    db[collName].find().forEach(function(d){
        db.getSiblingDB('new_db')[collName].insert(d); 
    }) 
});
