It shouldn't. Part of the migration is to remove any existing dovecot mailbox for the user. It does this by deleting the entire user's directory.
I just downloaded the file and checked. Oops, looks like I grabbed the post dsync mirror file. I've uploaded the correct file (pre dsync mirror). Downloaded it and confirmed I'm getting the following error on dsync mirror. dsync(webmail): Error: Sync failed for mbox file /var/opt/migrate/users/webmail/inbox: seq=4482 uid=4482 uid_broken=0 originally needed 10 bytes, now needs 12 bytes -- Michael Smith -----Original Message----- From: Timo Sirainen [mailto:t...@iki.fi] Sent: Tuesday, April 09, 2013 4:05 PM To: Michael Smith Cc: 'dovecot@dovecot.org' Subject: Re: [Dovecot] Sync errors trying to sync old mbox inboxes to dovecot On 9.4.2013, at 1.41, Michael Smith <msm...@giganews.com> wrote: > I tried importing the anonymized file, and there were no errors.

Maybe the problem requires something specific in the index files also?
