In practice, cyrus upgraded databases perfectly from even such an old install, and I simply copied via rsync the spools and databases and the seen files and had zero issues other than a corrupted tls database that I simply deleted and moved on. When you copy the databases and seen files to the new server, it doesn't work correctly? I am surprised by this.
