if I have multiple slapd servers running 2.4 can I update my master server to 2.5 with the new format and will the 2.4 mirrors be able to handle the new format or is it an all or nothing upgrade of all servers at once?

I would also backport:

commit dffa47ed752fd840e7a7cc0d1b95e4474f2de95b
Author: Howard Chu <hyc@openldap.org>
Date:   Fri Aug 6 22:13:47 2021 +0100

    ITS#9611 bconfig: canonicalize structuralObjectclass

until 2.5.7 is available, as that is also for 2.4 to 2.5 upgrade
compatibility.  It affects the dyngroup, dynlist, and memberof overlays.
