All, One of the concerns raised with regards to volume migration was the lack of tempest testing for the functionality. Since they I have had some interest indicated in helping this effort. So, to get things started I have created an etherpad to track development of such test cases and to share thoughts/plans for such work: [1] Please let me know if you have any questions with regards to this. Thanks to anyone who is interested/able to help with this effort! Jay [1] https://etherpad.openstack.org/p/replication-tempest-test-dev-planning
