It was quite some time ago I last upgraded a Cyrus instance, but my upgrade script did the following: - Run the _old_ version of db_recover. Just shutting down Cyrus is not enough, without this step db_upgrade can fail. - Run the _new_ version of db_upgrade. - Run "db_checkpoint -1" to force the log to be rotated. I think it won't be hard to implement steps 2 & 3 inside Cyrus, and I don't remember those steps taking a significant amount of time, but I don't know how it would be possible to implement step 1. However if the BDB version change does not bring a change to the on-disk DB log format, then it may be possible to skip steps 1 & 3.
