I need to run a mail-migration from a Dovecot with mail_attachment_dir / single instance storage enabled.

As mailboxes and mail_attachment_dir are rsynced I would normally run a

doveadm backup -u <user> -R -d dbox:<path to rsynced mailbox>/dbox

I tried it now with:

    doveadm -o mail_attachment_dir=<attachment-dir> backup -u <user> -R -d dbox:<path to rsynced mailbox>

Thought I'm unsure if doveadm use the option now for just the source (reverse destination) or also for -u / destination, which would be wrong for us?

How can I tell it the mail_attachment_dir the rsynced source / (reverse) destination uses?

Or do I have to start a Dovecot process and use imapc for the migration?
