Hi all,
I need to know the following if it is possible or not

I have a SQL 2K8 R2 cluster running, A/P with OS w2K8 -64bit

I have two questions:

1. Can I build SQL 2012 on it and migrate 2k8 to it and then get rid of 2k8

2. It is possible to run another Instance from the cluster(without effecting current prod environment) ?
What are the steps ?, anything special I need to consider ? any performance issues with #2


Which one is better approach ?

Please let me know, thanks

Data on installing SQL Server on a cluster is here: http://technet.microsoft.com/en-us/library/hh231721(v=SQL.110).aspx

Honestly, setting up clusters in Windows Server and SQL Server is specialized knowledge. I recommend getting someone to do it for you, who has experience in doing it. Watch what they do, learn from it, but don't try to set it up yourself unless the cluster is just for testing purposes and can be rebuilt multiple times if it doesn't go right.

The answer to both these questions is a question itself, "what capacity do the nodes have to support a second clustered instance of SQL Server"?

More to the point,do you even intend to cluster the 2012 instance or install it standalone
(maybe for use with AlwaysOn groups )?

Extra storage, extra IP addresses, extra resource consumption on the node(s).
