Note that the below may have unintended consequences if using Counter
column families. It actually can be done with the cluster running,
below is the least tricky version of this process.

a) stop writing to your cluster
b) do a major compaction and then stop cluster
c) ensure globally unique filenames for all sstable files for all cfs
for all nodes
d) copy all sstables to all new nodes
e) start cluster, join new nodes, run cleanup compactions
