dovecot - Feb 2012 - Failing: doveadm sync <--remote host--> dsync mirror

Hi --

I'm used to dsync my two mailservers running 2.0.16. 


Today, I did upgrade one server to 2.1, and doveadm sync is throwing to
following error:

mail> doveadm sync -f -u test ssh vmail at remote-host.tld dsync -v -f -u
test
doveadm(test): Fatal: All your namespaces have a location setting. It should be
empty (default mail_location) in the namespace to be converted.


Same error with old running command:

vmail> dsync -v -f -u test mirror ssh vmail at remote-host.tld dsync -v -f -u
test
doveadm(test): Fatal: All your namespaces have a location setting. It should be
empty (default mail_location) in the namespace to be converted.


Here's an excerpt of my doveconf -n:

mail> doveconf -n
mail_home = /var/mail/homedirs/%n
mail_location = mdbox:/var/mail/maildirs/%n
passdb {
  args = /usr/local/etc/dovecot/dovecot-sql.conf
  driver = sql
}
userdb {
  driver = prefetch
}
userdb {
  args = /usr/local/etc/dovecot/dovecot-sql.conf
  driver = sql
}


Reverted back for the time being (production servers) until I do understand the
issue.
Searching Google with "Fatal: All your namespaces have a location
setting." only shows closed bugs back in 2010.

Do I have to upgrade both servers to get syncing running?
Any hint, help is highly appreciated.

Thanks, 
Michael

JFTR: 

1) Upgrading both servers ends up in identical error messages.
2) After some investigation I came across a hidden upgrade info in [1],
   but 'doveadm dsync-server' doesn't run either :-(

I'm stuck, thus I did upgrade to 2.0.18 instead ...

Michael

I can confirm, that you fixed that issue successfully.

Thanks and regards,
