Hello everbody,

I'm a proud user of Dovecot 2.2.9 on Ubuntu 14.04 LTS. I currently migrate all my Linux services to a new Debian 8 Jessie Server. On this server I installed and configured Dovecot 2.2.24.

Now I search a way to migrate the two IMAP users I have on this server preserving all timestamps, folders and flags. Yes, only two ;-) I read the following two articles: http://wiki2.dovecot.org/Tools/Doveadm/Sync http://wiki2.dovecot.org/Migration/Dsync

But I must say, that either these articles are not so good, or I act quite dumb. I understand that I have to use "doveadm backup" against my old server to make a one sync with all properties of each mail. What I miss are proper examples and that there are so many options, I could set. But what confuses me most is the the configuration file in (http://wiki2.dovecot.org/Migration/Dsync) which I don't know how to reference? Am I using the wrong guides, are the article someway misleading or is there anything else I'm overlooking?

Thank you so much!

Hi!

here's a quick guide for easy sync:

Make sure your config is up to date.

# first round doveadm -o imapc_hostname=hostname -o imapc_password=password -o imapc_username=username backup -u local-username imapc:

if you want to use master password, use imapc_username *and* imapc_master_username.

# second round doveadm -o imapc_hostname=hostname -o imapc_password=password -o imapc_username=username sync -1 -u local-username imapc:

This all assumes that

doveadm user local-username

produces valid results
