Legacy Migration

If your source replica set is running a MongoDB version 4.4 or 5.0 and you are migrating to a destination replica set running MongoDB 6.0, you can the legacy live migration options described in this section to migrate to destination clusters in Atlas.

For legacy migration, you use the Atlas UI to either pull a MongoDB replica set into an Atlas replica set, or push data from a source replica set monitored in Cloud Manager to a destination in Atlas.

To live migrate a source sharded cluster, live migrate it to Atlas using this live migration procedure.

If you must use legacy live migration (push) to migrate a source sharded cluster, upgrade it to MongoDB 6.0 or later, and then migrate it to Atlas using this live migration (push) procedure.

You can also use self-managed tools to migrate manually, load files, and seed or import data.
