Migrating from 2.2 on one server to 2.3 on another
Hi all, I need to migrate a cyrus-imap setup from an older server running version 2.2.12 to a new server running 2.3.8. I've dug through the Cyrus wiki, the install-upgrade.html file, and other resources but I'm still running into a bit of a problem. I copied the entire /var/spool/imap directory over to the new server then tried running the reconstruct script. It re-created all the mailboxes, and I can see them properly in cyradm, but when I connect with Thunderbird only the top-level mailboxes show up. The child mailboxes don't appear, and all the users mail has been dumped into the top level inbox. What's the right way to migrate all the mail settings, preserving the tree structure of each mailbox?

Recommend how to move 31GB of mail to a new server
I'm preparing a new iMAP server and have 31GB of user mail on the current server to move. I'm looking for suggestions on doing the move with the minimum of down time as possible. Thank you for your suggestions, Jose ...

Did you use the -r switch with reconstruct. It recursively reconstructs sub-mailboxes. Jose ...

My strategy was to convert the old server into a unified murder and configure the new server as a standard murder node. I was then able to use the XFER function of Cyrus IMAP to move mailboxes transparently from the old server to the new one. There was no downtime other than for occasional reboots. The migration took a couple of weeks. To begin, I had to upgrade the old server to cyrus-imapd-2.3.8. I recommend great caution if you follow this example. I tested all of my procedures on a pair of test servers before using them on the production servers, finding a few bugs and other pitfalls along the way. For only 30 gigabytes, you might be better off just copying the files over, with IMAP down. It could only take a few hours. You can copy a sample from the live system to get an idea of the timing. -- -Gary Mills--Unix Support--U of M Academic Computing and Networking- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html

But unfortunately rsync will still have to scan each file to determine what has changed, and that can chew up a lot of time.

Yes, but hopefully less time that copying the files :) By default it will compare mtime and size and skip files which match. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au The nice thing about standards is that there are so many of them to choose from. -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C pgpdSHrdhwA3p.pgp Description: PGP signature Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
