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.

Planning to move from DSE to open source cassandra.

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.
