You can also add a new DC with the desired number of nodes and
num_tokens on each node with auto bootstrap disabled, then rebuild the
new DC from the existing DC before decommission the existing DC. This
method only needs to copy data once, and can copy from/to multiple nodes
concurrently, therefore is significantly faster, at the cost of doubling
the number of nodes temporarily.

Hi.
Is there a newer/easier workflow to change num_tokens in an existing
cluster than add a new node to the cluster with the other num_tokens
value and decommission an old one, repeat and rinse through all nodes?
