Basically it's all variations of alter keyspace command, depends on your
actual starting point.
ALTER KEYSPACE mykespace WITH replication = { 'class' :
'NetworkTopologyStrategy', 'replication_factor': '3', '' : 3,
: 4};
The best is to play a bit with multi DC setup with docker images and repeat
Dor Laor,
I like your approach. If I restrict the replication factor of a keyspace to
on premise data center and another to azure and attempt to split the
cluster?
Do you have some documentation I can refer to ?

I encourage you to try all of these in a lab/non-prod environment before
you do this in production. And take backups. This is risky and you should
think about what you're doing before you do it.
The most practical way to do this with no downtime is to spin up a new
cluster in Azure and either do
Not sure I understand correctly but if you have one cluster with 2 separate
datacenters
you can define keyspace A to be on premise with a single DC and keyspace B
only on Azure.

We currently have 2 databases (A and B ) on a 6 node cluster.
3 nodes are on premise and 3 in azure. I want database A to live on
onpremise cluster and I want Database B to stay in the Azure. I want to
then split the cluster into 2 clusters one onpremise (3 node ) having
Database A and
