you can either use get_range_slices to scan through all your rows and batch_mutate them into the 2nd cluster, or you can start a test cluster with the same number of nodes as the live one and just scp everything over, 1 to 1.
it's possible but highly error-prone to manually slice and dice data files (raw or as json).
