Our company looked at a number of different aspects of moving from CR to RS
(some 13 values in all).
One consideration was the ease of use/learning curve for RS over CR.
another was cost of licensing in the enterprise environment and of
maintenance.
RS came out a clear winner, even though we had (somewhat limited) experience
of using CR in VS, the learning curve to catch up knowledge in RS to that
currently in CR was a matter of days.
