I looked some upgrade documentations and am a little puzzled.
According tohttps://github.com/apache/cassandra/blob/cassandra-2.1/NEWS.txt, “Rolling upgrades from anything pre-2.0.7 is not supported”. It means we should upgrade to 2.0.7 or later first? Can we rolling upgrade to 2.0.7? Do we need upgradestables after that? It seems nothing specific to note upgrading between 2.0.6 and 2.0.7 in NEWS.txt Any advice will be kindly appreciated
