Moving away from DSE to apache cassandra is easy. If there are any keyspace with "EverywhereStrategy" strategies, change them to "NetworkTopologyStrategy" first.
particularly DSE system. Start in opensource mode and run sstable upgrade if needed.

What will be better way to do it. 1) I am thinking of introducing new datacenter with apache cassandra and replicating to that DC and after data replication remove DSE cassandra DC 2) Upgrading from current DSE version to later version of cassandra possibly 2.2 or 3.x Has anyone did it before any issues faced ?? Thanks Pranay.
