Are you currently using MongoDB as your database, but finding it difficult to manage and scale? It may be time to consider migrating to MongoDB Atlas, a fully-managed cloud database service that provides increased flexibility, scalability, and security. In this blog post, I will walk you through the steps and commands required for a successful MongoDB to Atlas Migration from local MongoDB to MongoDB Atlas.
Prerequisites
- MongoDB service is running on your local server
- Atlas cluster is created
- Network access is enabled in Atlas by whitelisting an IP address.
- MongoDB command line database tools installed
Atlas Migration Steps
1. Database dump from the local MongoDB server
To dump the data we need to use the mongodump command. See the example below:
mongodump --host localhost --port 27017 -u adminIn the above command, localhost is the host where the local MongoDB server is running. Port is used default for MongoDB. If you have a different port you can use that port. And admin is the MongoDB database user for your local server.
After executing the above command it will prompt for a password. Make sure to input the correct password for the user admin to dump successfully.
This step should export all the databases in the dump directory.
2. Restore to Atlas cluster
Now, you can use mongorestore command to restore the data from your local machine to the Atlas cluster.
The command is given below:
mongorestore --uri "mongodb+srv://your_cluster_username:your_cluster_password@your.atlas.mongodb.net"The above command will restore all the data to the Atlas cluster if the credentials and URL are correct.
Important
Make sure you change the correct values for your_cluster_username, your_cluster_password, and your.atlas.mongodb.net in the command above.
Conclusion
By following the steps given above you should be able to migrate data from your local machine to the Atlas cluster.
