Hi,
I have some strange things and at the end I am not sure if the migration
is (will be) OK.
I have a testuser for testing the mbox 2 Maildir migration. It did not
received new email during the following steps:
sudo -u testuser doveadm sync maildir:/home/testuser/Maildir
dsync(testuser): Warning: Mailbox changes caused a desync. You may want
to run dsync again: Remote lost mailbox GUID
4ca2fa0b9bb536564a470000e1afe915 (maybe it was just deleted?)
doveadm kick testuser
#sudo -u testuser doveadm sync maildir:/home/testuser/Maildir
##dsync(testuser): Error: Both source and destination mail_location
points to same directory: /home/testuser/Maildir
sudo -u testuser doveadm sync -R mbox:/home/testuser/mail
dsync(testuser): Error: Can't sync mailbox Public folders: Mailbox isn't
selectable
If I check the folders and mails in Thunderbird, everything seems OK
('Public folders' seems to be synced, too). However,
du -hsc ./*
320M ./mail
157M ./Maildir
I did not find anything that seem to be useful in order to get at a
conclusion.
Thanks for your help and suggestions,
Tamas

Hi,
I am experimenting with the migration.
I unset mail_location, thus it is empty and dovecot performs automatic
mailbox detection. Therefore I do not need per-user set of mail
location. I login as a testuser and do:
doveadm sync maildir:~/Maildir
It seems for me that in this situation the new Maildir becomes the
active mail delivery location at the time of the creation(?) or
completing the sync(?).
So if I want to rerun to avoid loosing new messages:
doveadm sync maildir:~/Maildir
I got an error that I can not sync to itself.
I guess this would not be a problem and would be rather simply.
However, if I issue a revers sync to be sure not loosing new messages:
doveadm sync -R mail/
doveadm(hegedus): Fatal: execvp(mail/) failed: Permission denied
dsync-local(hegedus): Error: read(remote) failed: EOF (version not
received)
(I tried to set a+x on my old mbox 'mail' directory and its contents)
I would appreciate any suggestion.
Thanks,
Tamas

Hi,
Tamas Hegedus, 29.01.19:
* Configuration uses mail_location = mbox:~/mails
* setup per-user mail location and do for each user individually in
a serial manner:
-- doveadm sync maildir:~/Maildir; mbox is synced to Maildir, long
running time
-- doveadm sync maildir:~/Maildir; rerun to do it for new messages
(fast)
-- add USER to userdb and set extra field to maildir:~/Maildir
users not present in the userdb should default to dovcot default;
conditionally optional: doveadm auth cache flush
IMHO there is no need to create or change special userdb entries. See
https://wiki.dovecot.org/MailLocation:
"By default the mail_location setting is empty, which means that
Dovecot attempts to locate automatically where your mails are."
Regards,
Christian
