The canonical source for Apache Cassandra upgrade documentation is
NEWS.txt. Here's the cassandra-2.2 branch NEWS.txt file - read all
entries since your current release:
https://github.com/apache/cassandra/blob/cassandra-2.2/NEWS.txt
The typical Cassandra upgrade path is through the latest of each major
release, so from 2.0.latest -> 2.1.latest -> 2.2.latest. However, you
may be able to go from your 2.0.14 to 2.1.latest - read NEWS.txt to see
if that is the case, and test your upgrades in your staging env!
