Problems Converting from Cyrus to Dovecot (cyrus2dovecot)
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

Problems Converting from Cyrus to Dovecot (cyrus2dovecot)
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,

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.

Complete migration from Cyrus on remote server
Hi All! I am working on a complete migration from an old solaris machine running Cyrus IMAP v2.3.14 and wish to migrate all users to a new ubuntu vm running Dovecot 2.0.19. What I have so far is a fully functional dovecot installation with LDAP / Dovecot SASL auth using Maildir++. My plan is to use Perdition IMAP proxy on a third host and migrate users a few at a time (see attached picture of

Recommended tool for migrating IMAP servers

Well, I've read the dsync documentation, but this warning has me a little worried: "Make sure destination is exactly as source, deleting/reverting any changes in destination if necessary" So I followed

fts crash
I've completed my mailbox rebuild - theoretically I should be free of corruption. I used dsync to export from mdbox to maildir (so should be clean) then used a virtual machine with Dovecot to import back to mdbox in another location. So...theoretically I should be free of all corruption now... Running an fts update - "doveadm search text -u user at domain.com xyzzyx" works on

Regenerating mdbox/sis
It's apparent I have some level of corruption in my mailboxes - something to do with the combination of mdbox, sis, and zlib. I should note that I know I have a mix of compressed and raw messages - if that makes any difference in identifying the problems. I think I need to somehow regenerate the mailboxes with issues. Is there a suggestion for how to accomplish this? Should I perhaps use

IMAP Migration Tools
Hi, I am looking for tools to migrate Mails from one IMAP-Server to another. Until now I have always used imapsync, but it seems very slow. Even over a 2x10GB/s connection I only get speeds of about 600KiB/s, because the programm always pauses betweeen every single mail. Does anyone here have a suggestion for an alternative? Thanks in advance Julian

MDBOX DSYNC error: Broken physical size in mailbox
Hi All, I currently have a small Dovecot server (Server A) and I've installed a second dovecot mailbox server (server B) and am trying to sync mailboxes from Server A to Server B. Both servers sit behind two dovecot directors on separate hosts and have identical config files (doveconf -n output below). Mailboxes on Server A are on an NFS mount.

dsync not copying all mail
Hi, I'm still trying to migrate from Dovecot 1.2.16 to 2.0.7 on FreeBSD. Previous attempts have failed with mails not being visible after the upgrade. Version 1.2.16 was migrated from maildir to dbox about a year ago via the convert-plugin. After previous attempts to "clean" the hybrid maildir-dbox situation I used imapsync to copy all mails from the old account to a new

UIDL and message migration
Hello, I'm in the process of migrating accounts between two dovecot servers. An old server running ancient 1.0.15 and a new server running 1.2.15. Account migration is going to be gradual and so i would like to use imapsync to move messages and subscriptions from one server to the other. The only problem so far is with POP users. After doing an account migration with imapsync, and
