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
This means that on Dovecot side there are messages after UID=16, but either:
a) UID=16 was expunged from Dovecot side or
b) UID=16 suddenly appeared on Cyrus side even though it wasn't there earlier. This isn't allowed by IMAP standard.
Dovecot can't insert UIDs, so it'll delete the folder and re-sync everything on the next run.
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.)
If you allow local access already that can do modification, use doveadm sync -1 after that.
