resynchronizing partial replica after ACL change

Hi,

I'm running a couple of partial replicas, where the replicated content is narrowed by provider ACLs. All is fine. Now, I need to extend the replicas with a new attribute, so I extend the ACL to allow reading of this attribute as well. How can I get the replicas synchronize this new attribute without downtime? Is forcing a full reload by slapd -c rid=1 a good solution? Does that incur the slapd restart downtime only, or would the replica database be in a crippled state until the full resync finishes?
