tip

Vibra stores its information in non-relational, document- and collection-oriented databases. It has deployed its databases in MongoDB in the cloud, in a service known as Atlas.

🚀 Step-by-Step Guide: Migrating MongoDB from Local to Atlas

One of the most repetitive processes is migrating relational and non-relational databases from our on-premises environment to a cloud environment. This short post explains how to configure Atlas, create a backup, and restore a database in a basic migration process.

1️⃣ Prepare MongoDB Atlas​

✅ Create a Cluster: If you haven't already, head over to MongoDB Atlas and set up a free cluster (M0). Follow this guide for detailed instructions. ✅ User Configuration: Set up a user with read/write permissions (e.g., migrator). ✅ Network Access: Add your current IP (or use 0.0.0.0/0 temporarily) in Network Access.

Get the Atlas Connection String:

✅ Navigate to your cluster in https://cloud.mongodb.com/ and click "Connect".

✅ Choose "Connect your application".

✅ Copy the Connection String (e.g., mongodb+srv://user:password@clusterxxx.mongodb.net/).

MongoDB on MongoDB Atlas (Free)

tip

MongoDB Atlas is a cloud service that allows you to deploy, manage, and scale MongoDB databases without having to manually configure servers. It's ideal for beginners because it offers a free tier with sufficient resources for small or test projects.

📌 MongoDB Atlas

✅ Free to start: 512 MB of storage (enough for development).

✅ Managed: You don't need to install MongoDB on your computer.

✅ Scalable: You can upgrade as your application grows.

✅ Secure: Includes authentication, encryption, and automatic backups.

✅ Global: You can choose your server region for best performance.

2️⃣ Export Local Data with mongodump​

✅ Backup Data Locally: run the following command:

  mongodump --host localhost --port 27017 --db vibra-db --out C://Users/USER/Personal/mongodb_backups_vibra_2025

✅ Restore Data to Cloud: run the following command:

  mongorestore --uri="mongodb+srv://username:Password@cluster0xxx.xxxx.mongodb.net/" C://Users/USER/Personal/mongodb_backups_vibra_2025/
