+=== Special Note
+
+* During a rebalance upgrade from 6.x (or any earlier version) to 7.x, in mixed mode (where you are communicating with Couchbase Server whilst some but not all nodes are upgraded), there is a known issue where data may be written to the wrong location.  
+The solution is to either upgrade to `3.2.9` or greater, or to pause application processing so there are no writes until you have upgraded all nodes.  
+If you encounter a similar situation during migration and need help with mitigation, please contact our support team.
+
