SENTINEL mailserver on ROCKY 9?

Has anyone installed this combination yet?

On my CentOS7 server I was using postfix/dovecot but it started giving me grief so I nuked it and installed SENTINEL instead (its a bit quirky but installed very smoothly). I’m migrating mails and webs over to a new ROCKY server in the next couple weeks, and just wondered if anyone had any “SENTINEL on ROCKY” success or horror stories…
