add sortvals after database loaded?

Environment: slapd: openldap-ltb-2.4.42-1.el6.x86_64 config: slapd.conf (file) database: mdb After a database has been loaded, can the sortvals option be added/changed without having to dump and reload the database? The slapd.conf (and slapd-config) man page doesn't mention any need for a reload, but wanted to verify. -Phil
