This works also without problems. So thanks for your help because this solves my problem. Let me know if i should test something more.
Sorry, I either made a mistake in my test setup or i can't reproduce it, but adding imapc:/tmp/imapc-username instead of imapc: doesn't help. I have circumvented my problem by changing the quota values directly in the database in my migration process.
But there is the following difference between using imapc:/tmp/imapc-username and plain imapc: if i backup a single, on both servers empty mailbox with different guids from the non dovecot imap server to the dovecot imap server, then plain imapc: throws some errors but works, imapc:/tmp/imapc-username throws more errors and only deletes the mailbox on the destination.

If instead of a normal Mailbox the special mailbox INBOX is used there are still more errors and both ways don't work. I think because backup isn't able to delete the mailbox INBOX on the destination site.
So i'll make sure that when i migrate an account the mail destination is really empty.
