Hello all, I would like to upgrade my Cassandra cluster from 2.1.12 to 3.7.
I have read the following documentation: · http://docs.datastax.com/en/latest-upgrade/upgrade/cassandra/upgrdCassandra.html · https://github.com/apache/cassandra/blob/cassandra-3.7/NEWS.txt but still had some questions: · The upgrdCassandra.html page says : “Upgrade from Cassandra 2.1 versions later or equal to 2.1.9 directly to Cassandra 3.0.x”, and I am not sure if this includes 3.x, my question is: Can I upgrade directly to 3.7? · Can I run a heterogeneous cluster, with one DC running 2.1.12 and another DC running 3.7? Thanks, -Razi
