[Dovecot] Transparent Migration from cyrus to dovecot

[Ed W]

Make use of the proxy feature.  You can add a "server" entry into your 
userdb, that way you can literally move users over one by one and flip 
their server location.  You can easily test individual users and move 
them over individually.

Works brilliantly
