Deployment Architecture

After setting replication factor to 2 at the global level, can I turn it off for some indexers?

Path Finder

After setting repFactor = 2 at the default level and running with that for awhile, can I now go in on a per indexer basis and set repFactor = 0 on some indexers so that only a few are replicating at a time and I can phase in index replication?

No. The repFactor setting must be the same across all peers in the cluster. All cluster peer nodes must set repfactor=auto for all clustered indexes.

Replication factor two means the cluster maintains 2 copies of all raw data, not that all indexers maintain a copy of data separately. Any specific reason you want to have some indexers not take part in replication (or not be part of cluster if they are not replicating)?
