Adding the dovecot.conf configuration from old and new servers:

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.
