Yes, this is the way we plan to migrate the mailboxes.

We are not planning on multiple runs of doveadm backup.  The question is
what to do with LMTP _while_ the doveadm backup migration is happening?

At the time when mailbox X get's migrated, the settings used for the
proxy will be removed, so user X cannot access the mailbox on the old
server anymore.  Given the size of some of the mailboxes chances are
quite high that there will be delivery attempts _during_ the migration
process.  That's what I am thinking about.

Cheers,
