Replication failed 3.0.5 -> 3.0.13

[Olaf Frączyk]

Hi,

I'm running 3.0.5.

I want to migrate to a new machine. I set up cyrus-imapd 3.0.13.

The replication started but it didn't transfer all mails.

The store isn't big 44GB, transferred was about 24 GB.

In the logs I see:

/var/lib/imap/sync/log-run failed: Bad protocol

I also executed thereafter sync client manually:

/usr/local/cyrus-3.0.5/sbin/sync_client -r

but nothing changed, in the log appeared:

Apr 20 15:37:23 ifs sync_client[27304]: Reprocessing sync log file 
/var/lib/imap/sync/log-run

The directory /var/lib/imap/sync/ on master is empty.

The directory /var/spool/imap/sync. on replica is also empty

What can I try to get it woring? Is there a serious problem with 
replication in 3.0.5? I wanted to avoid upgrade on the old machine.

Best regrads,
