+# Live traffic migration
+
+Live traffic migration intercepts HTTP requests to a source cluster and stores them in a durable stream before forwarding them to the source cluster. The stored requests are then duplicated and replayed to the target cluster. This process synchronizes the source and target clusters while highlighting behavioral and performance differences between them. Kafka is used to manage the data flow and reconstruct HTTP requests. You can monitor the replication process through CloudWatch metrics and the [migration console]({{site.url}}{{site.baseurl}}/migration-console/), which provides results in JSON format for analysis.

 # Assessing your cluster for migration
 
-
 The goal of the Migration Assistant is to streamline the process of migrating from one location or version of Elasticsearch/OpenSearch to another. However, completing a migration sometimes requires resolving client compatibility issues before they can communicate directly with the target cluster.
