<p>Hello, my name is Filipe</p>
<p>I'm migrating an email server to another new server. Accounts
have their storage configured as mdbox and their index being saved
in another storage device. I want to migrate all messages to the
new server with a new storage mode, sdbox.<br>
<br>
The new server will have storage settings set to sdbox for email
accounts:<br>
<br>
In dovecot's doc it says mdbox mode is the only one that supports
index storage on another device.</p>
<p><a class="moz-txt-link-freetext" href="https://doc.dovecot.org/admin_manual/mailbox_formats/dbox/#layout">https://doc.dovecot.org/admin_manual/mailbox_formats/dbox/#layout</a><br>
</p>
<p><i>"Index files can be stored in a different location by using
the INDEX parameter in the mail location specification. If the
INDEX parameter is specified, it will override the root mail
location for index files and the "map index" file (mdbox only).
"</i><br>
<br>
Even with this warning I performed the migration of some accounts
as a test.<br>
<br>
running the commands from server A to server B.<br>
<br>
"Server A" conf:<br>
dovecot version: 2.2.33.2<br>
<i>mail_location:
mdbox:/var/spool/imap/test=x.com:INDEX=/var/lib/imap/user/test=x.com</i><br>
<br>
"Server B" conf:<br>
dovecot version: 2.3.7.2<br>
<i>mail_location:
sdbox:/var/spool/imap/test=x.com:INDEX=/var/lib/imap/user/test=x.com</i><br>
<br>
command executed on server A to <span class="kgnlhe FwR7Pc"
data-term-type="tl" role="button" tabindex="0" data-sl="en"
data-tl="pt" dir="ltr">execute</span> message migration:</p>
<p><i>root@serverA: ~# doveadm sync -u test=x.com ssh root@<b>serverB</b>
doveadm dsync-server -u test=x.com</i><br>
<br>
In the end, the message migration was successful and the access to
the email account worked normally on server B.<br>
<br>
The question is whether dovecot has this support to move the index
when I use the sdbox?<br>
<br>
<br>
Thank you for your help<br>
