I’m not really keen on upgrading a major distro version unless there is a _really_ compelling reason to do so, especially as we have driver dependencies to Mellanox IB, Lustre, Tesla and Xeon Phi as well as a lot of ISV codes. However, it would be nice to hear what the current pain/benefit ratio of such an upgrade is.
