Rebuild (like bootstrap) only streams data from a single source replica per
range. IMO, therefore, the above process "should" end with a "repair all
nodes in both data centers with -pr" step. Otherwise, requests to the new
DC with LOCAL_X ConsistencyLevels or CL.ONE may violate consistency.

I have bcc:ed docs@datastax.com, in case they agree and want to modify the
above doc. :D
