I think I have a working dovecot installation, and the time has come to migrate my users. There are only 4 of us, so it can be done manually per user.

I looked at this page in the wiki

http://wiki2.dovecot.org/Migration/Dsync

but I am totally confused.

1st off, it uses doveadm, but with commands parameters that dont match my doveadm's man page. In fact they look more like dsync parameters. Is there an error, or am I totally misunderstanding

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.

2nd - if I assume its a dsync set of parameters, the imapc: at the end is a specification of location2. However, again my man page doesn't give any explanation of this. I am wondering, is this an example of an proxy 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.

3rd - where do the imapc_* parameters go in the configuration I can't find any reference to them in the wiki

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...
