similar to: Problems Converting from Cyrus to Dovecot (cyrus2dovecot)

Thank you for the reply. I did find imapsync whilst perusing Google. I will give it a shot, it sounds more realistic/reliable. I have a hoard of emails going back to 1999, so I want as few errors as possible :) On 11/7/15 3:31 PM, Philon wrote: > Hi there, > > I was in the same position, but for mutliple accounts.

Hello, Because it did not work ? In a similar situation, we where forced to use isync/mbsync in imap to imap mode because dsync did not work. It was reported here more than a year ago (May 2014). Time to time, I see the same report from other trying to use dsync to do a migration to dovecot. Dsync is a very appealing and elegant solution to this usage, but it does not always work in real

Hi, No, I tried fetching over imapc too exactly as you suggested. In my case it was not from cyrus, but from CriticalPath. isync was finally able to do the job, preserving flags and doing UIDs mapping. The most boring part was generating proper config file for thousands of accounts. A working imapc/dsync would have been better. Emmanuel. Le 26/11/2015 15:24, Sami Ketola a ?crit : > Hi,

Hi, With imapsync you will lose message UIDs which means that IMAP clients need to clear their local caches and redownload all messages. Why not use dovecot dsync over imapc instead? It tries to preserve UIDs and Flags. http://wiki2.dovecot.org/Migration Sami > On 07 Nov 2015, at 23:35, Forrest <those.lists at gmail.com> wrote: > > Thank you for the reply. I did find imapsync

Hi, I think you tried to read cyrus mails folders directly. I was talking about fething mails from cyrus over imapc connection.

v2.2.19 has many fixes related to dsync+imapc, which were found while migrating several million users from GMail. I'm not aware of any problems with it now. Also even before v2.2.19 dsync+imapc has been used to successfully do many large migrations. > On 26 Nov 2015, at 17:49, FUSTE Emmanuel <emmanuel.fuste at thalesgroup.com> wrote: > > Hi, > > No, I tried fetching

Hi there, I was in the same position, but for mutliple accounts. Still you might want to look at imapsync (https://github.com/imapsync/imapsync), isync and offlineimap. There are more alternatives listed at the imapsync homepage.

Hello, Using cyrus2dovecot (https://github.com/a-schild/cyrus2dovecot) I have migrated some test mailboxes from Cyrus (2.4.17) to Dovecot (2.2.9). The problem I'm having is that the seen status is in cyrus.index files, which cyrus2dovecot doesn't understand. Does anyone use cyrus2dovecot for migrations? If so, how do you deal with seen status when it is stored in the .index files?

Hi there, I have to migrate data out of a very old (debian 4) and buggy cyrus mailserver. About 40 Users with 200000 Messages each. Doveadm backup works quite well and gives me most of the mails. About every 100.000 Mail cannot be exported by cyrus. I do not want to bother about these errors. Maybe it is filesystem, maybe it is memory leak, or cyrus bug or whatever. My problem is that doveadm

Hello, list. I'm asking question not directly connected with dovecot. I'm planning a migration from cyrus-imapd to dovecot and i'm using cyrus2dovecot script (by Freie Universit?t Berlin) to convert mailboxes of users, but i'm wondering why size of mailbox in Maildir++ is so much bigger than mailbox in cyrus format after conversion: linux-a9qw:~/ # du -sh /mnt/imap/z/user/zinovik

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Anyone out there know of a tool that can convert a Cyrus MailDir format to Dovecot mbox? I have a user that I need to move over from a mail server running cyrus using MailDir format. At first I told him to setup second account with Thunderbird to our mail server and then use Thunderbird to move the messages over. But he has over 100K messages so

Hi: I have been using Dovecot for well over a year now and it has always worked with few problems. The mail setup is not simple... Postfix+MailScanner+ClamAV+Docvecot+MySql+postfix.admin... just to mention the major things. The system is CentOS 5.3 on VMware. The maildir is on an NFS share, index and control is local. About a month ago I thought I upgraded from 1.1.x to 1.2.x. by doing an

Hi, we are migrating from Cyrus 2.3.7 to Dovecot 2.2.13. We have ~7000 maildirs with ~500GB. Our goal is to do the migration without users have notice and with the shortest service downtime. The users use IMAP (with shared folders and ACL), POP3 and sieve filters. As a first choice, we tried the Dovecot's dsync tool. First tests were great, but we are not able to change the Cyrus auth

Dear all, Despite all the progress we are making in our attempt to make the migration as smooth and transparent for our users there are still some important unsolved issues. One thing that I can't figure out is how to preserve a user's flags that s/he has for mail in a shared mailbox. So far we tried 'doveadm backup -R' as well as the cyrus2dovecot script from here [1]. Both

Hello, So we've chosen to use dovecot as our imap mail server and replace our old cyrus server ! BUT : I would like to do a conversion of my imap accounts (and keep all theirs characteristics) from cyrus-imapd-2.2.12 in cyrus format to dovecot 1.1.3 in courrier format. I've tried those 3 tools : cyrus2courrier.1.5.ts cyrus2courier-1.3z4 imapsync (works well but very slow and should not

Hi, in our setup, we have a number of AD domains with an exisiting one-way trust between the local domain of the system (which I will call LOCALDOM in the following) and the domain containing the user accounts (which I will call TRUSTEDDOM in the following). The domain controllers run Windows Server 2012. Beginning with samba 4.4 we have an issue with authentication through pam_winbind on the

hi list, i'am doing a migration from cyrus ( 2.1.17 ) to dovecot ( 2.1.7). for mailbox migration i'am using this script : http://cyrus2dovecot.sw.fu-berlin.de/ To migrate a mailbox : /usr/local/sbin/cyrus2dovecot.pl -C /data/migration/spool/%h/user/%u -D /data/mail/foo.bar/%u at foo.bar -U /data/migration/flags/%h/%u.sub -S /data/migration/flags/%h/%u.seen test Directories

Damien, I was going down the path of public key authentication when I encountered problems. I've been discussing it off-line using the simple example of creating a key pair with no passphrase for an account on "myserver", then trying to connect to myserver using the "ssh -i id_dsa myserver" command. It's not working, so we're debugging now (see below). If you
