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

server. I was executing the command from production2 server only. It has the
