I think your OS now is windows 2003, right?<br />
in my openion &nbsp;the best way to do that and take your time for testing the new environmnet, is to build new cluster servers but as Hyper-V VM on any machine, after completeing the conversion if its is possible uninstall sql-server 2005 and upgrade the to windows 2008 R2 with hyper-v role, move the VM machines to them, <br />
there are many helpful deployment scenarios that can take benifit of Hyper-V, just google it.<br />

But i do not want to work on H-v VM. I have two existing boxex DL580G6 4 Quad 2.93 GHz processors with 128 GB of RAM. I have already evicted the Passive node.

 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We currently have a SQL 2005 active/passive cluster We currently have a SQL 2005 active/passive cluster running on two physical boxes with Windows Server 2003. We'd like to upgrade to SQL 2008 R2 with Windows server &nbsp;2008 R2 Any potential pitfalls we should be aware of, any precautions we might take ahead of time? We have the option of starting clean , but that has issues also as we will be using the same cluster names, and I'd overall prefer to upgrade the existing cluster if we aren't courting disaster. I would like to know the best possible steps to finish the task.Thanks.
