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 }
