title: Neo4j Casual Clustering benfits over High-Availability Clustering
body: <p>We are in the process of migrating HA cluster to Causal Clustering.</p>
  
  <p><strong>Is there any real advantage of migrating from HA Clustering to Causal Clustering?</strong></p>
  
  <p>Currently using REST End points only.</p>
  
  <p><strong>Is it possible to have causal clustering with just two Neo4j instances?</strong> </p>
  
  <p>Thanks.   </p>
