migrating/cloning 2.2 > 2.3?

[Voytek Eymont]

I have 2.2 installation on Centos 7, and, I'm trying to setup a new
server, and, 'clone' existing setup: Dovecot/Postfix/Mysql

on new Centos 7 installed from RPM  2.3.4.1 (3c0b8769e)

I then copied/overwrote from old to new /etc/dovecot/*.conf (but not
conf.d files), created self certs in place of old server certs

and, started Dovecot

is that totally dumb, and, how should I do this, or ?

upon starting dovecot and, trying to access mailbox from K9 client I see
in the log [1]:

what's my best way forward with this ?

I also see this in postfix log:
