removing second data center from live cluster

My cluster is currently running with 2 data centers, dc1 and dc2.  I would
like to remove dc2 and all its nodes completely.  I am using local quorum
for read and right.  I figure that I need to change the replication factor
to {dc1:3, dc2:0} before running nodetool decommission on each node in
dc2.  Is that the right approach?  Is there anything I need to watch out
for?
