cvt_cyrusdb  is used to convert a cyrusdb file between different database backends.  Note that you should
       not attempt to use the same file for input and output.

       Running without any options will list the available database backends.

       cvt_cyrusdb reads its configuration options out of the imapd.conf(5) file unless specified  otherwise  by
       -C.

       NOTE:
          Note  that  the file locations are NOT read out of the configuration file, and must be supplied on the
          command line.
