I think the RAC placement of these 12 nodes will become important. As the
12 nodes are placed in SimpleSnitch, which is not RAC aware, it would be
good to retain them in single RAC in the property file snitch also
initially. node repair is a safe option. If you need to change the RAC
placement, my

"As long as you correctly configure the new snitch so that the replica sets
do not change, no, you do not need to repair."
Is the following correct:
The replica sets do not change if you modify the snitch from SimpleSnitch
to NetworkTopologyStrategy and the topology file puts all nodes in the sam

As long as
What I understand is that SimpleStrategy determines the endpoints for
replica's by traversing the ring clock-wise.
NetworkTopologyStrategy determines the replica's by traversing the ring
clock-wise and taking into account the racks and DC locations.
Since the file used by PropertyFileSnitch puts
Yes, you must run a full repair for the reasons stated in the yaml file.

Hi all,
I want to add a data-center to an existing single data-center cluster.
First I have to make the existing cluster multi data-center compatible.
The existing cluster is a 12 node cluster with:
- Replication factor = 3
- Placement strategy = SimpleStrategy
- Endpoint snitch = SimpleSnitch
