dsync unstable? (other strange detail)

[Heiko Schlittermann]

Hi,

I'm trying to migrate from Cyrus (remote side) to Dovecot 2.2.24 (local).
On the local side the destinations folders, and indexes are empty.

The command I'm using is

doveadm \
        -o mail_plugins= \
        -o imapc_master_user=<cyrus-user> \
        -o imapc_password=<cyrus-password> \
        -o imapc_host=<cyrus-ip> \
        \
        -o imapc_ssl_verify=no \
        -o imapc_ssl=imaps \
        -o imapc_port=993 \
        backup -f -u "heiko" -R imapc: \
        || {
                rc=$?
                echo "EXIT: $rc" >&2
                exit $rc
        }

On successive runs of the above command I get:

    dsync(heiko): Warning: Deleting mailbox 'Serververwaltung.Mailinglisten Anforderung': UID=16 GUID= is missing locally
    EXIT: 75
    dsync(heiko): Warning: Deleting mailbox 'Serververwaltung.Mailman': UID=2 GUID= is missing locally
    EXIT: 75
    dsync(heiko): Warning: Deleting mailbox 'Serververwaltung.Servermeldungen': UID=514 GUID= is missing locally
    EXIT: 75
    dsync(heiko): Warning: Deleting mailbox 'Serververwaltung.Servermeldungen.AIDE': UID=188292 GUID= is missing locally
    EXIT: 75 
    dsync(heiko): Warning: Deleting mailbox 'Serververwaltung.Servermeldungen.AIDE.AIDE - 2012': UID=9343 GUID= is missing locally
    EXIT: 75

Any idea where to look next? Is 'doveadm backup' the wrong tool for such
migration? (I'd say with about 2.2.9 I had similar problems, but at
least it didn't stop at every subfolder.)

    Best regards from Dresden/Germany
