Of course Berkely DB cannot upgrade the MDB database; I was talking

I did not misunderstand you. I meant that Berkeley-DB could not do
automagic upgrades of its files in case the application-specific format
changes.
IIRC in former times with back-bdb and back-hdb there was also sometimes
the need to reload BDB files because the slapd-specific layout changed.
Admittedly I never had or needed those. I only noticed changes of hash
functions, and those did not need manual intervention.
Don't confuse the underlying database software (LMDB) with the databse
backend (slapd-mdb).
The slapd-mdb database backend had a format change that requires a reload.
This is, as Michael already noted, no different than when the slapd-bdb or
slapd-hdb backends (which made use of BerkeleyDB) had format changes.
Those type of format changes always require a reload regardless of the
underlying database software being used.
