Depending on your setup, you may also need to check for changes to <br>
additional software (e.g. amavis)<br>

<br>
I'm not sure if you've set it up already because it's unclear from the <br>
configuration you posted but, you may wanna have a look at: <br>
<a href="https://wiki.dovecot.org/Replication" rel="noreferrer" target="_blank">https://wiki.dovecot.org/Replication</a><br>
<br>
I suggest using replication after you've upgraded since earlier versions <br>
of dovecot had a few issues.<br>
