I guess it depends on the experience one has. This is a common process to
bring up, move, build full prod copies, etc.
What is outlined is pretty much exactly what I have done 20-50 times (too
many to remember).
FYI, some of this should be done with nodes DOWN.

cluster.
What if I also changed the cluster name in the Cassandra.yaml before restarting?
Is the data bound to the cluster name?

Subject: Re: Disconnecting two data centers
it's a bit tricky and I don't advise it, but the typical pattern is (say
you have DC1 and DC2):
1. partition the data centers from one another..kill the routing however
you can (firewall, etc)
2. while partitioned log onto DC1 alter schema so that DC2 is not
replicating), repeat for other.
2a. If
I’m running C* 2.1.13 and I have two rings that are replicating data from our
data center to one in AWS.
We would like to keep both of them for a while but we have a need to disconnect
them. How can this be done?
