Hi,
We're in the process of migrating our dovecot 1.x mail server to a
Dovecot 2.2.25 server. During the migration I'm moving from mbox storage
to mdbox.
I use the following method to do a one-way sync from our current mail
server to our new mail server (command executed on the new server):
doveadm -v -o imapc_host=oldserver \
-o imapc_user=$u \
-o imapc_master_user=$masteruser \
-o imapc_password="$masterpass" \
-o imapc_port=993 -o imapc_ssl=imaps \
-o ssl_client_ca_file=/etc/pki/tls/certs/ca-bundle.crt \
-o imapc_ssl_verify=yes \
-o mail_fsync=never \
-o mail_prefetch_count=20 \
backup -R -u $u imapc:
$u is replaced by the username I'm migrating.
The dsync command runs and exits with code 0 (all OK).
However, when I look at the subscriptions file on the new server, there
seem to be additional subscriptions that are not in the subscriptions
file on the old server:
7b0d681945d0fc5711560000ffff90ca
7c0d681945d0fc5711560000ffff90ca
7d0d681945d0fc5711560000ffff90ca
7e0d681945d0fc5711560000ffff90ca
7f0d681945d0fc5711560000ffff90ca
800d681945d0fc5711560000ffff90ca
Where do these come from? Is something wrong with the migration?
It also seems that subscriptions for IMAP folders that only contain
subfolders[1] are no longer present in the new subscriptions file:

Is this expected behaviour?

[1] On the old server a folder can only contain either messages or
subfolders, not both at the same time.
