It means that, when upgrading OpenLDAP, the previous configuration may not be compatible with the new OpenLDAP version.

False. Additions to the schema are always forward-compatible. Where we have renamed objectclasses,
we have kept the old name as an alias. So old configs will continue to work.

Hello Howard,

thanks a lot for this confirmation.

What would be the best practice to update the cn=schema,cn=config entry after an upgrade? It seems this schema is only available when we migrate slapd.conf to cn=config.

Maybe it could be interesting to provide an upgrage LDIF file that we could use to modify existing configuration?
