This procedure shows how to install a new version of Datastax Enterprise using the Advanced Package Tool, apt-get.
Please be sure to backup your configuration files before starting this process as apt-get overwrites any modifications you have made to them.
If you were previously using a version of Datastax Community, add the DataStax repository to the /etc/apt/sources.list using your username and password:
deb http://<username>:<password>@debian.datastax.com/enterprise stable main
Get the <username> and <password> from your DataStax registration confirmation email. If you don’t have the email, register on the DataStax web site.
Upgrade the node:
sudo apt-get update sudo apt-get install dse-full
If the prompt appears informing you of the disk space to be used, type Y to continue.
