I first upgraded the LDAP master. I tried various techniques, since I can't use db_upgrade directly. But the new 2.4.21 is happy to sync against the old 2.3.41, so I think I will simply run it in parallel until I am sure it has caught up. (You guys have a clever way to test and know when LDAP syncrepl has caught up?)
You should use the supported tools to migrate your database -- slapcat the master, then slapadd that to the replica... Same with rebuilding the master. That is the only officially supported upgrade path from 2.3 -> 2.4.
