I would say add your 3 servers to the 3 tokens where you want them, let's say :

{
    "0": {
        "0": 0,
        "1": 56713727820156410577229101238628035242,
        "2": 113427455640312821154458202477256070485
    }
}

or these token -1 or +1 if you already have these token used. And then just decommission x1Large nodes. You should be good to go.

Hi,

What is the best pratice to move from a cluster of 7 nodes (m1.xlarge) to 3 nodes (hi1.4xlarge).

Thanks,
