I have a new set of nodes and I'd like to migrate my entire cluster onto them without any downtime. I believe that I can launch the new cluster and have them join the ring and then use nodetool to decommission the old nodes one at a time. But, I'm wondering what is the safest way to update the seeds in the cassandra.yaml files? AFAICT, there is nothing particularly special about the choices of seeds? So, prior to starting decom, I was figuring I could update all the seeds to some subset of the new cluster. Is that reliable?
TIA, --nash
