Data Sync Between Stage Env and Prod Env --Sharding Cluster (4.2v)

Hi All,

We have a MongoDB community sharding cluster ((4.2-prod env) that has 1 mongos, 1 conf ( 3 nodes as a replica set), and 2 shards( each of them has 3 nodes as a replicaset). We want to install stage env for prod env. We’ll also install the same arch in stage env, but we are searching for a solution about how we can feed stage env from prod env.

Is Is there any recommendation? Is there a solution for sharding cluster stage env? There could also be a bash method that doesn’t affect prod environments much.
