Upgrading SFWHA v5.1GA to SFWHA v5.1 SP1
Currently I have a 6 node cluster (5 active, 1 passive) running SQL 2003. I would like to perform a rolling upgrade of all the nodes clusters from SFWHA v5.1 GA to SFWHA v5.1 SP1 without taking any downtime on any of the active cluster nodes.
My question is can a rolling upgrade be done when upgrading from SFWHA v5.1 GA to SFWHA v5.1 SP1? Do I have to completely shut down the entire cluster? Or can I upgrade the passive node first, then failover one of the active nodes to the passive node and then upgrade that node (original active node).
