Migration from one server to 2 new servers
Hi,
But there is no "doveadm backup" option in dovecot 2.0.9 version.
[root at production ~]# doveadm -backup
doveadm: invalid option -- 'b'
[root at production ~]# dovecot --version
2.0.9
Copy the contents by using "scp", will that work?
Thanks,
Kishore Potnuru

Migration from one server to 2 new servers
I tried this command also. It didn't work. It shows syntax again. Please
see the supported commands in dovecot 2.0.9 version. This doesn't support
replication also as per syntax, if i am not wrong. Please suggest me.
[root at production ~]# doveadm backup -u kishore at test.org.com
remote:vmail at production2.test.org.com
usage: doveadm [-Dv] [-f <formatter>] <command>

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?

2.2.2

Migration from one server to 2 new servers
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?

Migration from one server to 2 new servers
Fair enough but the command snippet I posted was taken directly from your earlier post dated Mon Jul 27 23:11:06 EEST 2020 and it does say ?production1??I just double-checked as well...
FWIW?the server order in the command you just pasted is the exact reverse from the Jul 27th post I mentioned above?
Here you appear to be exec?ing the command on prod2 and trying to pull from the remote of prod

Migration from one server to 2 new servers
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

Migration from one server to 2 new servers
Not sure if this matters but the prompt when attempting the ?doveadm backup? command shows it to be a ?production" server?
[root at production1 <https://dovecot.org/mailman/listinfo/dovecot> test.org.com]# doveadm backup -R -u kishore at test.org.com <https://dovecot.org/mailman/listinfo/dovecot>

Migration from one server to 2 new servers
No, but there is backup option on the new server. That's why the -R, which means "backup to here".

Migration from one server to 2 new servers
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:

Migration from one server to 2 new servers
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.

Oh, I am extremely sorry. I was confused when typing the issue. Please help
me in fixing the issue. Production1 is my old server. Production2 is my new
server. Typing here correctly. Ignore all previous one's.
The new version is:

[root at production2 ~]# dovecot --version
2.2.36 (1f10bfa63)
The old version is :

Dovecot HA/Resilience
Thank you Aki for the reply.
But I cannot disturb the version at present as it is a live server and
thousands of emails will circulate every hour.
Could you please suggest me how to create HA/resilience for the existing
environment. I have another server ready with the similar configuration.
Please provide any steps/link for me to proceed on this? It will be a great
help to me.
Thanks,
Kishore

Migration from one server to 2 new servers
I am executing the command from the new server. I was executing the command
from production2 server only. It has the backup option, but whereas
production1 doesn't have it. 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.

Urgent - Help needed
I am using pop3/imap, see the below file. We can't verify any logs? This is
working fine from last one year. as part of testing we just stopped the
services for 20minutes and restarted the dovecot and postfix server using
"service <dovecot/postfix> stop/start". No issues so far...
I would like know, if the application is reading the emails from the
server, do we have any log

Fwd: Load balancer for dovecot servers - Not able to send emails
Hi All,
I need your help on one of the issue in Dovecot.
I have the dovecot version 2.0.9 installed on RHEL linux 6.10 version. It's
a single/standalone Live server.
Now I have created another server with the same configuration for the
resilince purpose. I also tested and I am able to send the emails to both
of the dovecot servers separately/individually. They are working fine.
Now I have
