Howdy all- We're prepping for updating from 2.2.13->2.4.12 and I'm attempting to figure out some of the database differences between the two to make sure things go smoothly. We've already uncovered several issues in our testing that I've not been able solve searching through the list archives: 1) Seen state updates 2) the purpose of /var/lib/cyrus/db First, if I understand correctly, seen flags are now incorporated into the cyrus.index file in 2.4.x. What I can't figure out is if there is any way to manually trigger the reindexing of a single mailbox cyrus.index file. A reconstruct doesn't appear to do it (just using the -r flag). When we do the cutover over, we've a tight deadline, and what I'd like to do is reindex only the hot mailboxes, and then queue the remaining ones for later. I don't think my users will tolerate loosing all their Seen states, so I want to make sure we're preserving it while reducing the re-indexing impact so that the server is still responsive. Is it possible to trigger a reindex manually of a single mailbox? How are others dealing with this? Second, I don't understand the purpose of the /var/lib/cyrus/db in 2.4.12, it complained when the directory wasn't there, and I'm sure what it's storing now that it is. Everything on our 2.4.12 install is either skiplist or flat (sub), so what is that /db for?
