Let me know if you find a nice solution to migrate mailboxes per user, without downtime. I tried the use of the adviced userdb and using the override of the maillocation. But that doesn’t work with my mbox inbox.
I wanted to migrate then per user to an new server environment but still did not find a definitive guide on how to do this.

Hello,
I've got a Postfix/Dovecot server setup. Currently Dovecot is version 2.3.6, and it's using Maildir storage. The mailbox is:
mail_home = /home/vmail/mailboxes/%d/%n mail_location = maildir:~/mail:LAYOUT=fs
I'm wanting to convert from Maildir to sdbox. I looked at:
https://wiki2.dovecot.org/MailboxFormat
I was initially thinking mdbox but that's multiple messages per file, which I do not believe is what I want. Am I correct that in the sdbox format if a single message file is corrupted only that message is corrupt and not the rest of the messages as would be the case in a mdbox setup?
On the page:
https://wiki2.dovecot.org/Migration/MailFormat " maildir -> sdbox migration. Set mail_location=sdbox:~/sdbox and run dsync -u username mirror maildir:~/Maildir "
If I set mail_location=sdbox:~/sdbox will that put the user mailboxes in mail_home/sdbox?
So it would be:
/home/vmail/mailboxes/example.com/username/sdbox
I am needing to do this migration, but am paranoid about loosing mail or corrupting mailboxes. All of my users are virtual users and they are stored in a mysql database.
Thanks. Dave.
