Adding the dovecot.conf configuration from old and new servers:
========================================= My old server dovecot.conf (production1):
disable_plaintext_auth = no
listen = * log_path = /var/log/dovecot.log mail_location = maildir:/z1dev/mail/virtual/%d/%n/Maildir/ passdb { args = /etc/dovecot/passwd driver = passwd-file master = yes pass = yes } pop3_uidl_format = %g protocols = pop3 imap ssl = yes ssl_cert =
userdb { args = uid=vmail gid=vmail home=/z1dev/mail/virtual/%d/%n driver = static } mail_debug = no verbose_ssl = no
========================================= My New server dovecot.conf(production2):
disable_plaintext_auth = no
listen = * log_path = /var/log/dovecot.log
mail_location = maildir:/z1devenv/mail/virtual/%d/%n/Maildir/
passdb { args = /etc/dovecot/passwd driver = passwd-file }
pop3_uidl_format = %g protocols = pop3 imap
ssl = yes ssl_cert =
userdb { args = uid=vmail gid=vmail home=/z1devenv/mail/virtual/%d/%n driver = static }
mail_debug = yes verbose_ssl = no
# Enable the replication plugin globally mail_plugins = $mail_plugins notify replication
service replicator { process_min_avail = 1 }
dsync_remote_cmd = ssh -l%{login} %{host} doveadm dsync-server -u%u plugin { mail_replica = remote:vmail@production3.baplc.com }
service aggregator { fifo_listener replication-notify-fifo { user = vmail } unix_listener replication-notify { user = vmail } }
service replicator { unix_listener replicator-doveadm { mode = 0600 user = vmail } }
replication_max_conns = 10
imapc_host = production1.baplc.com imapc_password = vmail imapc_master_user = vmail imapc_user = %u
===================================

Not sure if this is the issue but the error says no password database is cfg’d…is that truly the case?
Maybe post a redacted config for the community to review…

Hi Aki & Dovecot team,
Just continuing with the previous discussion "Migration from one server to 2 new servers".
Hi,
I have tried the same way as per your suggestion. But it's throwing an error.
[root@production2 log]# doveadm backup -a All -R -u kishore@test.ba.com imapc: dsync(kishore@test.ba.com): Info: imapc(production1.baplc.com:143): Connected to xxx.xxx.xxx.xxx:143 (local yyy.yyy.yyy.yyy:45992) dsync(kishore@test.ba.com): Warning: imapc(production1.baplc.com:143): connect(xxx.xxx.xxx.xxx, 143) timed out after 30 seconds - reconnecting (delay 0 ms) dsync(kishore@test.ba.com): Info: imapc(production1.baplc.com:143): Connected to xxx.xxx.xxx.xxx:143 (local yyy.yyy.yyy.yyy:46014) dsync(kishore@test.ba.com): Error: imapc(production1.baplc.com:143): connect(xxx.xxx.xxx.xxx, 143) timed out after 30 seconds - disconnecting dsync(kishore@test.ba.com): Error: User initialization failed: imapc: Login to production1.baplc.com failed: Disconnected from server [root@production2 log]#
I looked into the production1 (old server) logs. I see the below error.
=============== Jul 28 11:14:23 auth: Fatal: Master passdb can't have pass=yes if there are no passdbs Jul 28 11:14:23 master: Error: service(auth): command startup failed, throttling
after the above error, I have commented "pass=yes" in production1 (old server) server, then I see the below error.
================ Jul 28 11:17:10 auth: Fatal: No passdbs specified in configuration file. PLAIN mechanism needs one Jul 28 11:17:10 master: Error: service(auth): command startup failed, throttling
Please suggest me on fixing the issue.
