Hi Timo,

I've tried to convert the Maildir from the first user:

convert-tool is going away. dsync is the new way to do conversion. For
example:

dsync -e 'dsync -r -O -o mail_location=maildir:~/Maildir'

This does a two-way sync between your primary storage and ~/Maildir. The
-r means that you want to keep ~/Maildir read-only. That's just in case
there are some bugs in dsync, because otherwise it does a two-way sync.

I suppose at some point I should make the command line also easier for
conversion purposes. :)

For the archive:
I'm using virtual users, without system access. So I had to add
'-u user' to both dsync commands. It was also necessary to set the
permissions of the auth-userdb socket to 0666. Because each user
has its own UID and GID per domain.

doveconf -n
…
service auth {
  unix_listener auth-userdb {
    mode = 438
  }
}
…

@Timo
dsync has written a few errors to the console:

dsync-src(user): Error: file_dotlock_open() failed with file /home/user/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index.log: No such file or directory
dsync-src(user): Error: Can't create mailbox INBOX: Internal error occurred. Refer to server log for more information. [2009-11-11 23:39:47]
dsync-src(user): Error: Trying to open a non-listed mailbox with guid=d32126213b2cfb4a145d0000ea7ee395

dsync-dest(user): Error: read() from proxy client failed: EOF
[after pressing the return key I had my propmt back.]

There were only a few 'Debug: …' messages logged at 2009-11-11 23:39:47

Where can I specify the path separator?
In the maildir  was a folder like:
        Maildir/.INBOX.Lists.Dovecot
In the mdbox is now this directory:
        mdbox/mailboxes/INBOX.Lists.Dovecot

I would have expected to find a structure like:
        mdbox/mailboxes/INBOX/Lists/Dovecot

Converting from one mailbox format to another one is now simple as never
before.
Assuming that the mail_location is set to mdbox:~/mdbox and before it
was maildir:~/Maildir:
execute:
        dsync convert maildir:~/Maildir

If you are root and want to covert the format of a mailbox from a
virtual user (w/o) system access, execute:
        dsync -u john.doe@... maildir:~/Maildir

Don't forget to update your sieve rules when switching to dbox or mdbox.
For example:
        fileinto "lists.dovecot";
becomes:
        fileinto "lists/dovecot";
