I am also migration away from mbox to in my case mdbox. I am not fully aware of something that allows you to do this without downtime.
To try to do as much as possible online, I have created an archive namespace and am moving the larger >5GB mbox files with old emails to that. So when the time is there to do convert active mailboxes, I have less to convert. Maybe this is helpful.

Hi,
I am not an professional system admin, but I am running a small debian mail server for many years. It is time to migrate from mbox to Maildir. There is a nice and clean description for doing this without service downtime at https://wiki.dovecot.org/Tools/Doveadm/Sync I have to set per-user config for mailbox type using userdb extra fields.
However, I miss some information and I can not find useful info by google.
The main question: dovecot will know that for some users the mailbox format is still mbox, but others already have Maildir. I do not see any hint that I should setup postfix/procmail for handling the delivery per-user basis. But I think I have to set this, too.
I have not learned much about userdb and it seems that dovecot was written for and used by experts. I mean that the docs/wiki is not enough for me: from the wiki page of userdb it will be for me difficult to setup one. Can you suggest some docs for dummies?
Thanks for your help, Tamas
