Running version 2.4.28.
Do not move to multi-master until you upgrade to a current OpenLDAP 
release.  I also strongly advise using delta-syncrepl based MMR.
What's the best way to change from provider / consumer to n-way master?
Down time is an option.



Can the current replication be stopped, reconfigured and then started
again?
You can do it with zero downtime.

<https://github.com/Zimbra-Community/zimbra-sources/blob/master/main/ZimbraServer/src/libexec/zmldappromote-replica-mmr> is a script I wrote to promote Zimbra replicas to be part of a MMR node. You would of course have to adapt it to your environment.
