How to change the RF and repair

 Just want to verify with group that what i am doing wrt RF is correct.

1. Nodes were running with RF=2
2. Stopped all the nodes, changed the RF to 4
3. Started all the nodes, verify the cluster ring using nodetool, all the
nodes are part of cluster
4. Ran nodetool repair on all the nodes
5. Ran nodetool tpstats on all the nodes to verify AE-SERVICE-STAGE is
completed and made sure that AE-SERVICE-STAGE is not active
6. Ran nodetool streams on all the nodes, made sure that streams are not
active

Can someone please correct me, if any of the above steps are wrong.

you need to do 4-6 one node at a time in 0.6.  (you can do it on all
at once in 0.7)
