[Dovecot] dsync not copying all mail

Hi,

I'm still trying to migrate from Dovecot 1.2.16 to 2.0.7 on FreeBSD. Previous attempts have failed with mails not being visible after the upgrade. Version 1.2.16 was migrated from maildir to dbox about a year ago via the convert-plugin. After previous attempts to "clean" the hybrid maildir-dbox situation I used imapsync to copy all mails from the old account to a new account. I would assume in this case I get a clean dbox-mailmap. I tried to run dsync on this new map but noticed a lot of mails are not syncing:

[vmail@mail ~]$ find /vmail2/new/bunbun.be/nick | wc -l 5329 [vmail@mail ~]$ find /vmail2/old/bunbun.be/nick | wc -l 6134

Any ideas? N.
