I was talking to my boss, and he's thinking of doing something in a couple months I've never done before. So I thought I'd get a heads up, and start asking now ...
We have a Win2012 R2 cluster, it runs 2 roles - a SQL 2012 instance (call it SQL1) and a file server instance (called it FILE1). We have another separate Win2012 cluster running a separate SQL 2012 instance (call it SQL2). He wants to move both SQL1 and FILE1 over to the other Win2012 cluster, so that we are left with only 1 cluster, running 2 SQL instances and 1 file server role. Using the same names and IP addresses. What I'm unsure about is the AD aspects. I've read how to uninstall a SQL 2012 clustered instance; seems straight forward enough. BUT ... does that also uninstall the AD account that the cluster creates? If not, do I need to remove anything from AD myself? (I'm assuming I need to create a new SQL instance on the other cluster, re-using the same name and IP addresses. I know that process creates new AD entries, but does it use existing entries if it finds any? Or is that a Bad Thing to do?). Or is there a better or cleaner way to move clustered roles and instances like this, from one cluster to another?
