it depends on how you installed it, package vs tar ball etc , Datastax has good documentation i suggest reading it http://www.datastax.com/documentation/upgrade/doc/upgrade/cassandra/upgradeCassandraDetails.html
in either case at a high level Step 1: Stop node Step 2: Backup your config files Step 3: will be to replace new binaries Step 4: will be to run nodetool upgradesstables Again there are some gotchas so i recommend reading above documentation thoroughly before proceeding On Wed, Sep 17, 2014 at 8:04 AM, Yatong Zhang <bluefl...@gmail.com> wrote: > Well, how to upgrade from 2.0.x to 2.1?
