You can start with a single cyrus server and turn it into cyrus murder 
easily later.  We just did that "migration" a week ago here, and it was 
totally painless.  As with everything, I'd suggest doing it in a test 
environment first.

Basically, all we did was bring up an empty murder master and 2 frontends, 
then we reconfigured the backend server to use murder and restarted it. 
Poof!  :)
