This isn't necessarily a concern for this list, but a few days ago I upgraded a site from cyrus 2.1.16 to cyrus 2.3.16 by using imapsync to transfer mail from the old server to the new one. This worked great (i.e. all metadata seems to have been preserved), however the old server was still collecting mail for the few hours it took to imapsync all the users (note that this is very slows and probably not appropriate for larger sites). My plan was to swap the servers and then do a final imapsync from the old IMAP server to the new one. For some reason, for some users the additional set of new messages is copied to the new server, and others they aren't. I couldn't figure out what the difference is, and don't want to spend too much more time on this because of the small number of messages in play, so I need some way to transfer a couple of dozen messages "by hand". In general, though imapsync seems to be a great way to "clean up" cyrus folders when switching servers. Had I known I would have sync problem later, I would have just taken the old server off line before syncing the messages. Before someone suggests that I should have just copied /var/lib/cyrus and the messages over to the new server, I didn't trust this because I couldn't get anyone to confirm the database files I had on the old 2.1.16 server -- the filenames were mostly not the same as this set: annotation_db duplicate_db mboxlist_db ptscache_db quota_db seenstate_db tlscache_db and the old server experienced a couple of devastating crashes which required me to cyrreconstruct all the user.user mailboxes a couple of times. It seemed pretty clear that the db files on the old server were a mess, and upgrading from anywhere from libdb2 to libdb4.3 to libdb4.8 seemed sketchy as well. The old server is such an old debian system that apt-cache depends doesn't seem to work any more because the package servers have changed. (Yeah, I could probably find the source packages somewhere, but then there are a lot of things I could do given infinite time.) ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
