I have run DSE and Apache Cassandra in the same cluster while migrating to DSE. The versions of Cassandra were the same. It was relatively brief -- just during the upgrade process -- but they run just fine together. My experience was in the Cassandra 1.1 and 2.0 time frame, but I would expect it to be similar now. Exceptions, of course, would be the DSE additional tools like SOLR, Spark, OpsCenter, Graph, DSE Authentication, etc. Sean Durity lord of the (C*) rings (Staff Systems Engineer – Cassandra) MTC 2250 #cassandra - for the latest news and updates
