Subject Re: [RELEASE] Apache Cassandra 2.1.0
Date Wed, 17 Sep 2014 20:37:11 GMT
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.

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. I don't know if it's still true, but be careful ;)
