"Replication strategy may not be changed without wiping your data and starting over."
To start with I want to have all my nodes in a single DC. But over a time of period, nodes will be placed in multiple DCs. In that is it safe to start using "RackAwareStrategy" even if nodes are in a single DC? So, that when I start using multiple DCs, data wiping won't be required.

into the data directory on the target node, but I'm not sure why you
would want to do that.
I wrote http://wiki.apache.org/cassandra/Operations to answer the
other questions in more detail. :)
