Moving data from Cyrus 2.3.7 (RHEL) to 2.3.16 (Invoca)

[Simpson, John R]

Greetings all,

	We have been running Cyrus 2.3.7, as packaged by Red Hat (cyrus-imapd-2.3.7-2.el5) for some time, and we're upgrading to 2.3.16 (cyrus-imapd-2.3.16-8, thanks Simon) to support replication.  We will be deploying new servers for 2.3.16, not upgrading the existing servers.  In the past, we have simply rsync'd /var/spool/imap and /var/lib/imap to the new servers, but this doesn't seem like a good idea when dealing with different versions and packagings.

	Which files, directories, and databases do I need to copy to the new servers?  Am I correct in assuming that we will need to recover the databases and mailboxes to make them compatible with the newer version?

	Thank you in advance.  I apologize if this is a basic question -- I don't have a lot of operational experience with Cyrus, and have not been able to find specific instructions in the documentation, wiki, or mailing list.  Links to anything I missed would also be appreciated.

Best regards,

John
