Hi all,

What is the best way to upgrade SQL Server 2008 R2 with the latest CU on a 4 node failover clustering?

Let's say i have active/active 4 node cluster and each node has 1 instance running on it.

One more question for sql 2005:

Is it possible to upgrade sql 2005 from SP3 CU8 to SP4 CU3 directly without installing SP4 first?

1. pick up any node to start with if all 4 nodes are active, otherwise start with passive node. Then you can failover instance to upgraded node and upgrade rest nodes.
2. have to apply sql2k5 sp4 first.
