      Hi,
I'm trying to migrate IMAP mails from dovecot 1.1.20apple0.5 (osx) to
dovecot 2.2.33.2 (ubuntu). I'm using "doveadm backup" to migrate my data.
It works fine for all subfolders, but the root INBOX stay empty on the new
server. I suspect a problem related with hierarchy separator ("." on
previous server, "/" on new) or with the namespace prefix (set to "INBOX/"
on new server). Any hint?
Thanks.
show there is no messages in INBOX
# doveadm mailbox status -u (myuser) all INBOX
INBOX messages=0 recent=0 uidnext=1 uidvalidity=1553630060 unseen=0
highestmodseq=1 vsize=0 guid=d54cd42849739b5cb5790000ed87e144
firstsaved=18446744073709551615
show there is messages in subdirectory
# doveadm mailbox status -u (myuser) all INBOX/Sent
INBOX/Sent messages=253 recent=0 uidnext=8721 uidvalidity=1263328366

guid=bfb2e03fdce327671e82bf173b1ccb8b firstsaved=1553634631
The command I'm runnning on the new server to migrate data:
# doveadm -o mail_fsync=never backup -R -u (myuser) imapc:
# My config on the new server:
