mbox 2 Maildir

Hi,

I am experimenting with the migration.
I unset mail_location, thus it is empty and dovecot performs automatic 
mailbox detection. Therefore I do not need per-user set of mail 
location. I login as a testuser and do:
doveadm sync maildir:~/Maildir

It seems for me that in this situation the new Maildir becomes the 
active mail delivery location at the time of the creation(?) or 
completing the sync(?).

So if I want to rerun to avoid loosing new messages:
doveadm sync maildir:~/Maildir
I got an error that I can not sync to itself.

I guess this would not be a problem and would be rather simply. However, 
if I issue a revers sync to be sure not loosing new messages:
doveadm sync -R mail/
doveadm(hegedus): Fatal: execvp(mail/) failed: Permission denied
dsync-local(hegedus): Error: read(remote) failed: EOF (version not received)

(I tried to set a+x on my old mbox 'mail' directory and its contents)

I would appreciate any suggestion.
Thanks,
Tamas
