Legacy Migration

If your source and destination clusters are running a version before MongoDB 6.0.13, you can use legacy migration options described in this section. For legacy migration, you use the Atlas UI to either pull a MongoDB replica set or sharded cluster into an Atlas replica set or sharded cluster using the Atlas UI, or push data from a source replica set or sharded cluster monitored in Cloud Manager to a destination replica set or sharded cluster in Atlas. You can also use self-managed tools to migrate manually, load files, and seed or import data.
