I'm trying to migrate an old Cyrus 2.5 server to Dovecot 2.3.19 using
doveadm backup -R, which works for all folders but the INBOX itself,
which always stays empty.
The Cyrus side uses altnamespace:no and unixhierarchysep:no, it's used
as imapc: remote in doveadm backup -R with imapc_list_prefix=INBOX
Dovecot uses the following namespace to migrate into:
namespace inboxes {
inbox = yes
location =
mailbox Sent {
auto = subscribe
special_use = \Sent
}
### some more folders omitted ###
prefix = INBOX/
separator = /
subscriptions = no
}
Hi!
When syncing mailboxes from other server, you should use migration config file,
which has **no** auto=subscribe or auto=create folders, as these can mess up
with synchronization.
Please see https://doc.dovecot.org/admin_manual/migrating_mailboxes/ for more
details.
Does a migration config file specified with doveadm -c <file> add to and
overwrite the existing Dovecot configuration for the time the command
runs, like the -o options, or do I need to start a separate server with
a full configuration to e.g. have my authentication and mailbox location
available?
Ralf
It does not add/replace/overwrite configuration, you provide a fresh config
file which is used *instead of* the default dovecot.conf.
You don't need to run a separate instance necessarely, although in some larger
migrations this has been used as well.
I created now a separate instance with a modified configuration file
with no auto=subscribe (or create), no replication and an empty storage.
doveadm config -n is attached.
Unfortunately the result is identical to my previous tries:
doveadm -o namespace/subs/location=mbox:/var/dovecot/subs -o
imapc_user='someuser' -o imapc_password='secret' -D backup -n INBOX/ -R
-u someuser@somedomain imapc: 2>&1 | tee /tmp/doveadm-backup.log
Nov 03 09:06:35 dsync(someuser@somedomain): Warning: Mailbox changes
caused a desync. You may want to run dsync again: Remote lost mailbox
GUID c92f64f79f0d1ed01e6d5b314f04886c (maybe it was just deleted?)
doveadm mailbox status -u someuser@somedomain all INBOX

highestmodseq=1 vsize=0 guid=c92f64f79f0d1ed01e6d5b314f04886c

Any ideas what else to try or how to debug that further?
I can send you the full log to your personal address, if that helps ...
Ralf
You should rm -rf the target folder first. Can you attach `doveadm -D backup`
logs? Check that it won't contain passwords.
The mailbox directory did NOT exist before, therefore no need to rm -rf it.
I send the logs to your private address only, I feel not comfortable to
post them on the list.
