Description

On https://docs.opsmanager.mongodb.com/v4.0/tutorial/add-existing-mongodb-processes/ documentation, under "Prerequisites" we should have some notes for importing a PSA replica set into Ops Manager 4.0.x and 4.2.x.

The keyfile contents for the PSA replica set been imported into Ops Manager must match the existing keyfile been managed in the target project. Otherwise, the import process will fail for the Arbiter node due to authentication failure.
