[CentOS] Extending schema on Centos DS

I am running CentOS DS server (version 8.1.0) in a mixed master setup. I am looking for the best way to extend the schema without breaking replication?

I was successfully able to extend the schema on my two servers manually but replication broke after a restart of dirsrv.

What is the correct way to extend the schema on a MMR setup, I haven't been able to find much on the subject?

Thanks,

Chris
