I would be most happy to be wrong. You'll find you are definitely right. You'll have to shut it down. You can make it a lot shorter by moving the 'start cyrus-imapd' before the 'remove the metapartition_files from partition-default' step. Cyrus won't mind about the spare files being there. But doing it on the fly - ouch. Definitely not designed for. It probably wouldn't be a massively hard problem to solve, but it's such a rare case that nobody much cares enough to make it work.
