How to migrate a mongodb replica set from one kubernetes cluster to another using replication

My goal is migrating data via replication from one mongodb replica set to another mongodb replicaset.

I am attempting to migrate data from replicaset a (on kubernetes cluster a) to replicaset b (on kubernetes cluster b)

See my attempt below:

bitnami/mongodb helm chart https://github.com/bitnami/charts/tree/master/bitnami/mongodb

global:
  namespaceOverride: mongodb
architecture: replicaset
auth:
  rootPassword: "<redacted>"
  replicaSetKey: "samevalue"
replicaCount: 1
serviceAccount:
  create: true
rbac:
  create: true
persistence:
  storageClass: "mongodb"
  size: 250Gi
externalAccess:
  enabled: true
  autoDiscovery:
    enabled: true

Steps

1. Create replicaset A on kubernetes cluster A
2. Create replicaset B on kubernetes cluster B
3. Add a member from replicaset B to replicaset A using the command

rs.add( { host: "<host>:27017", priority: 0, votes: 0 } )

member fails to join

rs0 [direct: primary] admin> rs.status()
