title: Changing Snitch on live cluster in datastax 4.5
body: <p>I have 8 nodes in one region and now i want to add new node in other region.Presently i m using ec2snitch  ,after adding node to new region i need to change snitchs of all nodes to ec2 multiregion snitch.</p>
  
  <p>Now my question is, does this change will impact my current running cluster? and what would be the best practice for doing this .</p>
  
  <p>Thanks</p>
