+Synchronize Data From a Pre-8.0 Source Cluster to an 8.0 Destination Cluster 
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To migrate data from a 6.0 or 7.0 source cluster to an 8.0 destination 
+cluster: 
+
+- Use ``mongosync`` to migrate data from your source cluster to a 7.0 
+  destination cluster.
+- Upgrade the 7.0 destination cluster to 8.0.
+
+Synchronize Data Between Two 8.0 Clusters
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To migrate data between two 8.0 clusters:
+
+- Use :ref:`mongodump` to export data from the source cluster.
+- Use :ref:`mongorestore` to import the data into the destination cluster.
+
+For limitations on using ``mongodump`` and ``mongorestore``, see 
+:ref:`mongorestore-behavior-access-usage`.
+
+Alternatively, you can :ref:`downgrade your 8.0 source cluster <8.0-downgrade>` 
+to 7.0, migrate your data into a 7.0 destination cluster, and then upgrade the 
+destination cluster to 8.0.
