Abstract:
A method for upgrading a set of controller nodes in a controller cluster that manages a plurality of forwarding elements in a way that minimizes dataplane outages. The method of some embodiments upgrades the control applications of a subset of the controller nodes before upgrading a decisive controller node. Once the decisive controller node is upgraded, the method switches the controller cluster to use a new version of the control applications.

Claim (Index 23):
The method of  claim 22 , further comprising reassigning management of the forwarding elements from the second subset of controller nodes executing the older controller state to the upgraded first subset of controller nodes by configuring the forwarding elements to use the second set of tables to direct forwarding behavior instead of the first set of tables.
