[Dovecot] migration from IMAP/POP3 courier server to a remote dovecot server
Dear all i'm planning a transparent migration from a courier server that provides both IMAP and POP3 access to users to a remote dovecot server with both IMAP and POP3 access. I have to migrate about 2500 users for 250 GB of space. I'm using dovecot 2.2.5.4 on debian6 squeeze. To make a transparent migration i have to maintain old IMAP UIDs and POP3 UIDs, so i've read http://wiki2.dovecot.org/Migration and http://wiki2.dovecot.org/Migration/Courier and http://wiki2.dovecot.org/Migration/Dsync And decided that probably the best tool to use is Dsync, as the courier-dovecot-migrate.plhttp://www.dovecot.org/tools/courier-dovecot-migrate.pl script works only locally. I've tested the dsync following instructions reported above but after the migration of one test-account the client re-download messages. If i want to keep both IMAP UIDs and POP3 UIDs i have to sync both imapc and pop3c with two commands? doveadm -o imapc_user=foo -o pop3c_user=foo -o imapc_password=bar -o pop3c_password=bar backup -R -u user@domain imapc: doveadm -o imapc_user=foo -o pop3c_user=foo -o imapc_password=bar -o pop3c_password=bar backup -R -u user@domain pop3c: Or imapc is enough? Do you have any suggestion? Thanks -- /*/ nik600 http://www.kumbe.it

to give some more information, i've set pop3_uidl_format = UID%u-%v on the courier-side i get this UIDL answer: UIDL +OK 1 1378040847.Vfe11I12801312M172099.myserver.cloud923 2 UID2-1378040947 3 UID3-1378040947 4 UID4-1378040947 5 UID5-1378040947 on the dovecot-side i get this UIDL answer: UIDL +OK 1 UID1-1378127599 2 UID2-1378127599 3 UID3-1378127599 4 UID4-1378127599 5 UID5-1378127599 2013/9/2 nik600 nik...@gmail.com Dear all i'm planning a transparent migration from a courier server that provides both IMAP and POP3 access to users to a remote dovecot server with both IMAP and POP3 access.

Re: [Dovecot] migration from IMAP/POP3 courier server to a remote dovecot server
Ok, it seems i found the problem, i was missing the plugin declaration into
dovecot.conf
imapc_host = mail.foo.com
imapc_features = rfc822.size
pop3c_host = mail.foo.com
namespace {
separator = /
inbox = yes
}
protocol doveadm {
mail_plugins = $mail_plugins pop3_migration
}
disable_plaintext_auth = no
pop3_uidl_format = UID%u-%v
And then using command:
*doveadm -o imapc_user=foo -o pop3c_user=foo -o imapc_password=bar -o
pop3c_password=bar backup -R -u user at domain
http://dovecot.org/cgi-bin/mailman/listinfo/dovecot pop3c:*
The only doubt i have is how to sync both imap and pop3, i've seen
that if i made a pop3c sync ath then impac sync gives an error, and if
execute imapc and then pop3c it gives an error too.

Dear all
i'm planning a transparent migration from a courier server that provides
both IMAP and POP3 access to users to a remote dovecot server with both
IMAP and POP3 access.
I have to migrate about 2500 users for 250 GB of space.
I'm using dovecot 2.2.5.4 on debian6 squeeze.
To make a transparent migration i have to maintain old IMAP UIDs and POP3
UIDs, so i've read
http://wiki2.dovecot.org/Migration
and
http://wiki2.dovecot.org/Migration/Courier
and
http://wiki2.dovecot.org/Migration/Dsync
And decided that probably the best tool to use is Dsync, as the
courier-dovecot-migrate.plhttp://www.dovecot.org/tools/courier-dovecot-migrate.pl
script
works only locally.
I've tested the dsync following instructions reported above but after the
migration of one test-account the client re-download messages.
If i want to keep both IMAP UIDs and POP3 UIDs i have to sync both imapc
and pop3c with two commands?
doveadm -o imapc_user=foo -o pop3c_user=foo -o imapc_password=bar -o
pop3c_password=bar backup -R -u user@domain imapc:
doveadm -o imapc_user=foo -o pop3c_user=foo -o imapc_password=bar -o
pop3c_password=bar backup -R -u user@domain pop3c:
Or imapc is enough?
Do you have any suggestion?
Thanks
