Steps to replace a node with a new node, such as when updating to newer hardware or performing proactive maintenance.

Warning: Only add new nodes to the cluster. A new node is a system in which the DataStax Distribution of Apache Cassandra™ (DDAC) has never started. The node must have absolutely NO PREVIOUS DATA in the data directory, saved_caches, commitlog, and hints. Adding nodes previously used for testing or that have been removed from another cluster, merges the older data into the cluster and may cause data loss or corruption.
