You can modify a deployment's configuration and topology, including its MongoDB versions, storage engines, and numbers of hosts or shards. You can make modifications at all levels of a deployment's topology from a top-level sharded cluster or replica set to lower levels, such as a replica set within a sharded cluster, or an individual process within a replica set. You can also modify standalone processes.

您无法更改副本集或分片集群的单个成员。 您只能更改整个集或集群。
If a setting isn't available for a MongoDB resource, you can make changes using only the Ops Manager or Cloud Manager application.
