Hi Gerard, You should probably add a new datacenter following this procedure : http://docs.datastax.com/en/cassandra/2.1/cassandra/operations/ops_add_dc_to_cluster_t.html
You will just have to make sure to configure all the nodes of the new nodes to use mnt + mnt2 instead of mnt + mnt2 + mnt3. Make sure to have enough space (disks / nodes) to handle your whole set of data in the keyspace you want to load and it should be ok. I think that this is the easiest approach, you don't need to care about SSTable at all, Cassandra does it for you.
