Hi,
I have tried the same way as per your suggestion. But it's throwing the below 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 161.2.11.119:143 (local 161.2.12.152:45992) dsync(kishore@test.ba.com): Warning: imapc(production1.baplc.com:143): connect(161.2.11.119, 143) timed out after 30 seconds - reconnecting (delay 0 ms) dsync(kishore@test.ba.com): Info: imapc(production1.baplc.com:143): Connected to 161.2.11.119:143 (local 161.2.12.152:46014) dsync(kishore@test.ba.com): Error: imapc(production1.baplc.com:143): connect(161.2.11.119, 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. I have also copied the dovecot.conf from both the servers below.
========================================= 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 =

===================================
Please suggest me.

Hi!
Kishore, you got the command wrong..
doveadm backup -R -u username-goes-here imapc:for this to work, you need to configure following things:
imapc_host = old-host-name imapc_password = master-password imapc_master_user = master-user-name
and on the old host you need
passdb { args = /etc/dovecot/passwd.masterusers driver = passwd-file master = yes pass = yes }
This should let you pull the mails from the old host to your new host over IMAP.
You should probably also look at

Hey Kishore…
I believe this is the thread I mentioned earlier. It is quite long and spans a monthly barrier (Feb\Mar 2012) so if you use the “Next\Previous message” links, you need to be sure to pick up the thread in each monthly archive. I have provided links to the first post of the thread in each archive here:
https://dovecot.org/list/dovecot/2012-February/133718.html https://dovecot.org/list/dovecot/2012-March/134110.html
Also, mention of a working syntax for the remote side command can be found in this post:
https://dovecot.org/list/dovecot/2012-February/081425.html
I’m sure one of the Dovecot devs will chime in at some point but in the meantime, hopefully the above will offer some relief…

I seem to recall a post a while back where, due to the age of the remote end, the remote side command had to be entered in the command executed on the local side.
Do you have dsync on the 2.0.9 machine?

This is what my understanding. May be I am also wrong here.
Backup option is there in my new server, production2.
When I use the command with -R option from new server, it is connecting to old server, Production1 and giving the output of the doveadm backup command in old server to get the data. If you see the command and error I posted, it shows the same.
Sorry just incase if I am wrong.
Kishore
Well that option set still doesn’t look correct…
Here is the doveadm option set from my 2.2.2 server which is several weeks\months before 2.2.36…

Though I am executing from production2, I am seeing the below error. Is it becasue production1 server doesn't have that option? Please let me know, if it is confusing. the “doveadm backup” command shows it to be a “production" server… then per Kishore’s earlier posts, the machine where this is being attempted is running 2.0.9…not 2.2.36
