Upgrade Cassandra version to 2.0

[Santosh Shet <sa...@vista-one-solutions.com>]

Dear All

The version of Cassandra is 1.2.3 in Dse 3.0 which is currently installed in my machine.  Now I want to upgrade Cassandra to latest version 2.0.

Do I have to upgrade DSE 3.0 to DSE 3.2( which is latest version available) but still it has Cassandra version 1.2.11 which I don't want.
Or Is it possible to only upgrade Cassandra in the existing DSE which is installed.

Could you please provide some inputs on this.

Thanks in advance,

Santosh

Are you in production? If so, read :

DSE is a patched version of Cassandra, the patches are the closed-source
value add by Datastax. You therefore cannot upgrade only the Cassandra part
of DSE, as you are unable to apply the same patches.
