What is the current OLC way to replace the nis schema with the rfc2307bis schema?

There are hacks published, but I couldn't find a document that takes advantage of OLC, removes the nis schema, and installs the rfc2307bis schema. It feels like something that I would do often enough that I would want to be able to do it one ldapmodify operation.

There is a problem. There wasn't delete support in OLC 2.4 2012 in http ://www.openldap.org/lists/openldap-technical/201204/msg00245.html.

OLC does support delete in 2.5 as of 2013 https://www.slideshare.net/ld apcon/whats-new-in-openldap.

Since that has been established, what is the least hacky way to replace the nis schema with the rfc2307bis schema in 2.4?
