Use nodetool move and change the tokens one at a time to the values suggested by Tomas.
for background http://www.datastax.com/docs/1.1/references/nodetool#nodetool-move Each move will take some time, you will see the node state change from UP to MOVING in the output from nodetool ring. When it's back to UP the move is done. *Note:* before making the change you should increase your RF to 3 and run a repair with nodetool (using the -pr option). This will make sure your data is fully distributed to all nodes. You should also make your code use the QUOURM CL . Hope that helps.
