Whether you use two versions or not, I suggest not automatically
converting the config file to the config directory. It can play
havoc with any configuration management that may be in place.

My suggestion would be runtime log messages that say "no config,
see /etc/dovecot.d/README" where one could find instructions to
convert dovecot.conf to doveconf.d files.

The problem with a MESSAGE warning (not to say it shouldn't be
used), is it could easily go un-noticed.
