dovecot - Sep 2020 - migrations from 2.2.36

Hi
I started migrations dovecot cluster from 2.2.36.4 (debian) to 2.3.8
(cetos8) .I read https://wiki2.dovecot.org/Upgrading/2.3

In 10-director.conf I must disable director_doveadm_port like:
#director_doveadm_port = 2424

and add:
.....
service doveadm {
? inet_listener {
??? port = 2424
? }
}

Is this correct ?



the rest of the contents of the file


service director {
? unix_listener login/director {
??? mode = 0666
? }
? fifo_listener login/proxy-notify {
??? mode = 0666
? }
? unix_listener director-userdb {
??? mode = 0600
? }
? inet_listener {
??? port = 9090
? }
}

service imap-login {
? executable = imap-login director
}

service pop3-login {
? executable = pop3-login director
}
?
# Enable director for LMTP proxying:
protocol lmtp {
? auth_socket_path = director-userdb
}
?
service managesieve-login {
??? executable = managesieve-login director
}
?
protocol doveadm {
??? auth_socket_path=director-userdb
}
