# Migration tools and high-level migration steps
<a name="tools-steps"></a>

After you deploy MongoDB Atlas on AWS, you can use the following tools to migrate data from the source (a public cloud, your data center, or a third-party DBaaS provider) to MongoDB Atlas on AWS, with minimal impact on your applications. There are three basic steps for the simplified data migration process:

1. Deploy your new cluster.

1. Live migrate the data.

1. Cut over in seconds when ready.

You can use the following migration tools for the second step:
+ [Atlas Live Migration Service](live-migration.md)
+ [MongoDB Relational Migrator](relational-migrator.md)

## Choosing the right tool for your migration

If you are already running MongoDB instances in your source environment, we recommend that you use the Altas Live Migration Service for minimal impact to your applications. If you want to migrate a relational database workload to MongoDB, use the MongoDB Relational Migrator.
