MongoDB provides several ways of importing data to your Atlas cluster.
Before migrating data to your Atlas cluster, see:
Live migration keeps your cluster in sync with the remote source until you cut your applications over to Atlas. Please note:
You cannot live migrate to/from a free tier or shared cluster. Consider modifying your cluster to scale up to an M10+ instance.
You cannot live migrate to a MongoDB Atlas version 4.2 cluster. Consider creating a version 4.0 cluster and upgrading to version 4.2 after the migration.
See the Atlas Migration Readiness Checklist article before running a live migration.

For alternative ways of migrating data to your Atlas cluster, see:
