Hi Boying,

I'm not sure I fully understand your question here, so some clarification may 
be needed. However, if you are asking what steps need to be performed on the 
current datacenter or on the new datacenter:

Step 1 - Current DC
Step 2 - New DC
Step 3 - Depending on the snitch you may need to make changes on both the 
current and new DCs
Step 4 - Client config
Step 5 - Client config
Step 6 - New DC
Step 7 - New DC
Step 8 - New DC

Hi, all,

I read the document about how to adding a new data center to existing clusters 
posted at 
http://www.datastax.com/documentation/cassandra/2.0/cassandra/operations/ops_add_dc_to_cluster_t.html
But I have a question: Are all those steps executed only at the new adding 
cluster or on  existing clusters also? ( Step 7 is to be executed on the new 
cluster according to the document).

Thanks

Boying

 But I have a question: Are all those steps executed *only* at the new

 the new cluster according to the document).
