I am talking with a client about moving from CentOS 3.7 to CentOS 4.x and migrating their uw-imap to cyrus-imapd but in the process, would want to do a clean install. This is problematic in that if I want to preserve the IMAP flags for all the users INBOX and other mail folders, I would have to move them to another computer and then use something like imapsync (which I've used before) to copy the mail and all of the folders from the old IMAP server to the new one.
I haven't a clue where/how uw-imap stores these flags to even begin to presume that I can successfully move them (though I suppose I can rsync the /var/spool/mail and the users folders)...does anyone know where these flags are stored?

You can't rsync uw-imap folders to a cyrus install, because they use entirely different file formats. Cyrus uses a one-message-per-file directory hierarchy similar to a usenet news tree, whereas UW by default uses flat files. The ONLY thing you can do is imapsync them, unless cyrus provides some kind of import tool.
That said ... for writable flat-file folders, the flags are stored in each of the mail messages themselves, in X-Status and similar headers. The UIDVALIDITY and other folder-level values are stored in the fake message with subject "DO NOT REMOVE ..." that is inserted at the top of each folder.

---- OK - then if I copy the files/folders over to another server running uw-imapd, the flags are in the message headers of each email in each mbox file so I don't need to copy anything other than the mail itself and a similar version of uw-imap should be able to serve the status flags via imapsync which is what I was worried about.
