    Description

      Write a "recovery" method on the MigrationManager for the case where it steps down (with a bunch of migrations going on) and then starts up again on a another primary. In this case the new MigrationManager will have to "inherit" the active migrations and wait for them to complete before doing another round.

      *Write a JS test to test this, including querying the config.migrations collection at points to check it is correct.
