Indeed that's a problem. Dsync as a separate command has been deprecated 
and now dsync is a symbolic link to doveadm. The currently correct way 
to invoke dsync commands is as is described on this wiki page, but the 
man pages were not updated to reflect this.

imapc is a dovecot storage backend, which acts as an IMAP client. 
Migration is implemented as a reverse backup from location2. imapc can 
be used as a sort of proxy but in this case it is literally used as a 
storage engine, when reading from location2 and writing to your new mailbox.

I've expressed my opinion before that the wiki's structure seems rather, 
ehm, circular. Every page seems to assume you already know absolutely 
everything except for the details provided by that page. It would be 
helpful if every topic had a proper introduction, explaining what every 
thing is, why it exists, and under what circumstances it could help you 
solve what problem. The last discussion of this did not end with a call 
to action.

local.conf is fine (should be included from dovecot.conf), or otherwise 
just dovecot.conf. You can also just specify a series of '-o imapc_*' on 
the command line, you say you only have 4 users...
