Hello,
I have two separate Windows Failover Clusters running on my current class C subnet and we have finally ran out of IP address space and need to move to a subnetted class A. My question is how exactly to proceed with changing each of the nodes, as well as re-adding the iSCSI storage disk (as the SAN's IP will also be changing to the new class A subnet) to each of the nodes. Here is the planned change:
Current IP subnet that all WFC nodes and services live on - 192.168.2.X
New IP subnet that all WFC nodes and services will live on - 10.10.1.X
I have read a bit of information about the steps required to perform, but as I will be changing EVERYTHING on my network, including the domain controllers, SANs, etc, etc, - what is the order of steps I need to follow? I would assume that I need to change the cluster's IP information first before changing our domain controllers, as it will need to verify the permission to even make the changes. Am I correct in thinking this way? If anybody has any good information about this or steps to follow, I would appreciate it very much.
Thank you all,
