There is a diagram in the bottom of the following article, and there are 5 nodes hybrid environment which combined by Failover Cluster Instances and AlwaysOn Availability Groups
So my question is if all of the 5 nodes must be in the same windows cluster?
Can we create two windows cluster for them? such as two in one windows cluster, and three in another Windows cluster, is it possible?
If it is possible, may I know can we move the primary replica between two window clusters?
