Hey All, Recently I've tried to upgrade (hw upgrade) one of the nodes in my cassandra cluster from ec2-small to ec2-large.
However, there were problems and since the IP of the new instance was different from the previous instance. The other nodes didnot recognize it in the ring. So what should be the best practice for a complete hardware change of one node in the cluster while keeping the data that it has. Regards, Utku
