[Dovecot] problem migrating from maildir to dbox
Hello, we want to migrate Mail folders from Maildir to dbox without downtime. We change the mail_location to dbox in 10-mail.conf and restart dovecot. After that we use dsync -u user mirror maildir:~/Maildir. The problem is that if INBOX exists the dsync create a new folder with name like b5893c0a93ff694e551200002dfa3112 Can I migrate to the existing INBOX? or How can I merge the 2 INBOX folders? Thanks for your help! Regards,

My transition from maildir to mdbox occurred so: /Maildir - an old place of mail /Mailbox - new
mail_location=%h # set home for all users maildir:/Maildir/user_name
script:
for i in echo "select name from user|$sql
do
res=$(dsync -u $i backup mdbox:/Mailbox/$i)
if [ $res -eq 0 ];then
echo "update user set home=\"mdbox:/Mailbox/$i\" where
name=$i"|$sql
echo "$i migrated" >> $log
fi
done

Have you created the dbox directory before running dsync? And opened it with some tool? I tried with your config and it worked fine.
The reason why these duplicate INBOXes happen is when INBOX exists both in source and in destination when dsync is run. Typically this means that you've created the destination INBOX already by e.g. logging in or delivering a mail there or something..
While the dovecot is running with the new mail_location to dbox, I try to migrate the maildir content. This is the reason because INBOX already exists.

You changed the mail_location globally to dbox? You should instead do it one user at a time, like explained in http://wiki2.dovecot.org/Tools/Dsync (with initial dsync done before user's mail_location is ever changed).
Otherwise you'll get these duplicate INBOXes and you'll need to somehow manually figure out how to merge them. There are "doveadm move" and "doveadm mailbox delete" commands for example.
