This procedure shows how to install a new version of the DataStax Enterprise binary tarball to replace an existing installation.

Before performing the installation, be sure to back up your configuration files for future reference.

Upgrading a node and migrating the data

  1. Download the DataStax Enterprise tarball using your username and password:

    $ curl -OL http://<username>:<password>@downloads.datastax.com/enterprise/dse.tar.gz
    

    Get the <username> and <password> from your DataStax registration confirmation email. If you don’t have the email, register on the DataStax web site.

  2. Create a directory for the new installation and move it to that directory.

  3. Unpack the DataStax Enterprise 3.1 tarball:

    tar –xzvf <dse-3.1 tarball name>
    
  4. If you customized the location of the data in the old installation, create a symbolic link to the old data directory:

    cd <new install location>
    ln -s <old data directory> <new install location>/<new data directory>
