dsync connection issue
I'm trying to move from my exising server to a new site. In preparation for this I've set up the new server as per the first attachment.
I've added additional (temporary) setting to the new site as per these instructions
https://wiki2.dovecot.org/Migration/Dsync
but when I try to do a backup with the following command from the old to the new site
sudo doveadm -D -o imapc_user=user1@oldserver -o imapc_password=pw-oldserver backup -R -u user1@newserver imapc:
I get
Error: User initialization failed: imapc: Login to 'oldserver' failed: Disconnected from server
I can connect to both sites without any issues
openssl s_client -crlf -connect newserver:993
openssl s_client -crlf -connect oldserver:993
Not sure what I'm missing.
Have also included the config for the old site
Thanks,
Leo

Did you check logs on the old server?
Aki
The logs on the old server are as follows

Since both of your servers are running dovecot it would be probably better to use native doveadm protocol (over ssh pipe if required) to do the migration instead of using imapc.
something like:
doveadm backup -u user1@newserver -R ssh oldserver sudo /usr/bin/doveadm dsync-server -u user1@oldserver
allowing sudo and ssh login with keys.

Thanks for you suggestion, but I couldn't quite get it to work.
I ended up rsyncing the mail folders (there were only a few email accounts) a temporary folder on the new server and then used dsync to restore the mailfolders.
Thanks again for your help
