Step-by-Step Guide: Migrating Data Between MongoDB Atlas Accounts Easily

Introduction

Migrating a MongoDB database between different hosts can be necessary for several reasons, such as moving your local database to a remote server, creating backup copies, or even pulling production data for local testing and development.

Thankfully, MongoDB offers an effortless way to handle this through mongodump and mongorestore, a powerful tool that simplifies the migration process.

Whether you're switching between MongoDB Atlas accounts or moving from a local to a cloud database, this guide will show you how to migrate your data seamlessly in just a few steps.

Step 3: Dump Data to a Directory

mongodump --uri "SOURCE-CONNECTION-STRING-URI"

• 'SOURCE-CONNECTION-STRING-URI' is URL you are using to connect your app to MongoDB -- either local something like mongodb://127.0.0.1/someDatabase or can be remote server like mongodb+srv://yourapp:<password>@cluster0.xyz123.mongodb.net/someDatabase

• The command will save a dump of your entire database into a folder and in the directory where the command was run.

Step 4: Restore Data from Directory

mongorestore --uri "DESTINATION-CONNECTION-STRING-URI"

• Run the above command in the same folder where the dump was created and that's it.
