dovecot - Feb 2013 - dsync: Invalid server handshake

Hi list,

I recently tried to backup mailboxes from an older server machine to
a new one in order to move the service to the new machine.
Both machines are in the same LAN, I used this command:

dsync -R -u username backup ssh -i .ssh/id_rsa username at 192.168.1.11
/opt/local/bin/dsync

and I get this error:

dsync-local(dz): Error: Invalid server handshake: dsync-server	 2
dsync-remote(dz): Error: Invalid client handshake: dsync-client 1

# lokal machine: dovecot 2.0.19apple1 running on Mac OS X 10.8.2 Server
using standard Apple-Dovecot-Configuration

# remote machine: 2.1.12 running on Mac OS X 10.4 using PAM authentication


I cant seem to find any documentation to this error, nor do I find any dsync
entries
in the logs of both machines. Does anyone have a hint?


Thank you,

Dusan

You are using different minor-versions of Dovecot; v2.0 v/s v2.1.
Dovecot v2.0 uses dsync 'version 1', and v2.1 uses dsync 'version
2'.

If there aren't to much big mailboxes, I would stop imap/pop3 on the old
server, move the mailboxes to the new server and start iamp/pop3 on the
new server.
Or you have to update Dovecot to version 2.1 on the older server. Then
you should be able to dsync between both servers.
