The following approach covers move MongoDB documents from one collection to another. With the help of mongoose, we will move a MongoDB document from one collection to another. Make sure that in the schema of both the collections all the fields are the same.
Install mongoose:
Step 1: You can visit the link Install mongoose to install the mongoose module. You can install this package by using this command.
npm install mongoose
Step 2: Now you can import the mongoose module in your file using:
const mongoose = require('mongoose');Database: We already have documents in our Source and Destination collection before moving as shown below:
Source Collection before moving: Our source collection before the movement will look like this.
Source collection before moving
Destination Collection before moving: Our destination collection before the movement will look like this.
Destination collection before moving
Implementation:
Create a folder in which you can add two files model.js and index.js which are shown below:
- model.js: It contains schemas for the source collection and destination collection and exports models of both the schemas.
- index.js: It contains code for moving a document from the source schema to destination schema.
Run index.js using the command:
node index.js
Output:
Output in the console after executing index.js
Source Collection after moving: Our source collection after the movement will look like this.

Destination Collection after moving: Our destination collection after the movement will look like this.
