ImapMigration

This section lists various tools that may be useful for converting or copying Cyrus IMAP folders to Dovecot. Most have some issues with preserving either “read” or “replied-to” status, there may be other quirks.

Aside from the read / unread status of messages, imapsync makes this ridiculously easy. For Debian and Ubuntu, imapsync is available from the software repository, so installation should be as simple as:

apt-get install imapsync

Source code is available from http://www.linux-france.org/prj/imapsync/

• http://www.majid.info/mylos/weblog/2006/03/08-1.html cyrus2maildir.py looks promising
• http://madness.at/projects/ cyrus2courier old, has some flaws
• http://trukenmueller.de/cyrus2dovecot cyrus2dovecot also works when the cyrus server is offline and/or broken
• http://bendiken.net/2005/11/03/courier-imap-to-dovecot-migration-script for Courier, I need cyrus
• http://batleth.sapienti-sat.org/projects/mb2md/ wrong format, would be multi-step process

• http://www.linux-france.org/prj/imapsync/ think I have used this before
• http://barnson.org/node/81 article, a bit dated, possibly useful
• https://webware.cc.umanitoba.ca/imapcp.cgi web-based, not secure for private data
• http://hein.roehrig.name/iicopy/ needs c-client, could be pain
• http://directory.fsf.org/all/MailboxCopy.html maybe

This script needs to be run on the Cyrus server, as it looks at imapd.conf for settings. It requires Python 2.4. It looks like Cyrus 2.1.3 is the version on this server, and the script can’t parse the skiplist format.
