 Description   

Verify that during the upgrade the commands with readConcern level:snapshot are rejected.

Summary:

  • Verify that snapshot read concern is rejected when the cluster is not fully upgraded and then allowed in FCV 3.6 and 4.0 once each binary has been upgraded.

Design:

  • Copy the existing jstests/multiversion/cluster_upgrade.js test, and add assertions on the behavior of snapshot reads at each stage.
