And upgrading from 0.21.0 to 0.21.0 (no upgrade and should succeed):

> Test suite for verifying compatibility between Mesos components
> ---------------------------------------------------------------
>
> Key: MESOS-2372
> URL: https://issues.apache.org/jira/browse/MESOS-2372
> Project: Mesos
> Issue Type: Epic
> Reporter: Vinod Kone
> Assignee: Niklas Quarfot Nielsen
>
> While our current unit/integration test suite catches functional bugs, it
> doesn't catch compatibility bugs (e.g, MESOS-2371). This is really crucial to
> provide operators the ability to do seamless upgrades on live clusters.
> We should have a test suite / framework (ideally running on CI vetting each
> review on RB) that tests upgrade paths between master, slave, scheduler and
> executor.
