hi guys

I have built a dev platform that I now want to expand out to multi node.

Can I expand the cluster (rings).

current rings are

account.builder, build version 14
262144 partitions, 1.000000 replicas, 1 regions, 1 zones, 4 devices, 0.77 balance
The minimum number of hours before a partition can be reassigned is 1
Devices:    id  region  zone      ip address  port      name weight partitions balance meta
             0     1     1       127.0.0.1  6002      sdb1   1.00         65   -0.77
             1     1     1       127.0.0.1  6002      sdc1   1.00         66    0.76
             2     1     1       127.0.0.1  6002      sdd1 2000.00     131006   -0.00
             3     1     1       127.0.0.1  6002      sde1 2000.00     131007    0.00

would like to do

 account.builder, build version 12
262144 partitions, 3.000000 replicas, 1 regions, 3 zones, 12 devices, 0.00 balance
The minimum number of hours before a partition can be reassigned is 1
