copy/clone mongoose document from 1 identical schemas

Question

Is it possible to copy the content of a document to another one with mongoose?

Ex:

we have 2 schemas, 1 videoSchema and 1 videocloneSchema:

var videoSchema = new mongoose.Schema({
    videourl: String
});

var videocloneSchema = new mongoose.Schema({
    videourl: String
});

How would I go about copying the contents of videoclone onto video? _id is not important, only thing important in the schema is the videourl
