Just the upgrade should copy the seen data in - but note it needs to be done with the NEW code, you won't get a reindexing just by reconstructing with the old reconstruct. > 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.

The mailbox will be reindexed at the moment when it first gets opened. The rest will be re-indexed by cyr_expire when it runs regularly, if nothing touches them before then. > Is it possible to trigger a reindex manually of a single mailbox?
