Is it possible to do a rolling upgrade to a Win 2008 R2 (x64) SQL 2012 Multi-instance Cluster from Win 2003 R2 (x64) 2005 Multi-instance cluster? If possible, I would like to add a 2008 R2 node to the cluster, upgrade the SQL server to 2012 on the that passive
node, failover to the upgraded node, and evict the old ones. My goal here is to keep the current names of the SQL instances running in production.
