+
+A: IPFIX flow monitoring requires the Linux kernel module from Open

+
+Q: Should userspace or kernel be upgraded first to minimize downtime?
+
+ In general, the Open vSwitch userspace should be used with the
+ kernel version included in the same release or with the version
+ from upstream Linux. However, when upgrading between two releases
+ of Open vSwitch it is best to migrate userspace first to reduce
+ the possibility of incompatibilities.
