You should run a nodetool repair after you copy the data over.  You could also use the sstable loader, which would stream the data to the proper node.

We are planning to move data from a 2 node cluster to a 3 node cluster. We are planning to copy the data from the two nodes (snapshot) to the new 2 nodes and hoping that Cassandra will sync it to the third node. Will this work ? are there any other commands to run after we are done migrating, like nodetool repair.

Thanks all.
