Hi, I have a quick question about migrating a cluster.

We have a cassandra cluster with 10 nodes that we'd like to move to a new DC and what I was hoping to do is just copy the SSTables for each node to a corresponding node in the new DC (the new cluster will also have 10 nodes).  Is there any reason that a straight file copy like this wouldn't work?  Do any system tables need to be moved as well or is there anything else that needs to be done?
