Yep! "bisect the token ranges" if you want to be fancy about it.

I see what you are saying. So basically take whatever existing token I have
and divide it by 2, give or take a couple of tokens?

Yes, Cassandra partitioner is based on hash ring. Doubling number of nodes is
the best cluster exctending policy I've ever seen, because it's zero-overhead.
Hashring - you get MD5 max (2^128-1), divide it by number of nodes (partitions)
getting N points and then evenly distribute them across you
