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?

Re: [RELEASE] Apache Cassandra 2.1.0
When I upgraded I went from scripts to create tables and load data then tested on a clean server (no previous install of Cassandra). So far things are running well for me. I discovered else Cassandra will look for previous installs and if you do not follow the Cassandra's team recommendation you will run into issues. But not everyone can start with a clean install due to too big schema or other complications. Good Luck though. -Tony On Wednesday, September 17, 2014 12:34 PM, olek.stas...@gmail.com olek.stas...@gmail.com wrote: When I upgraded my system from 1.2.x to 2.0.x there were simple hint: never upgrade before target release does not have at least 5 on third place. versions before x.x.5 are unstable and aren't ready for production use.
