Cassandra: decommissioning seed node

Cassandra's conceptual questions: I have a 5 node cluster. Now that all nodes are loaded, a list of seed nodes that each node knows about matter? If I plan to decommission the seed of a node, do I need to update the configurations of other nodes and remove the IP address from the list of nodes from the list of seeds of the node, or does it not matter since all the nodes are fully joined?

If you disconnect the seed of a node on the boot and work ring, the cluster will continue to work as each node is already taken. However, the correct procedure before decommissioning a node seed is to select an existing node as a new seed by adding its IP address to other nodes cassandra.yaml; removing from all cassandra.yaml the old seed address.
