Question : Exchange 2007 SCC Cluster

Hi
We are running Exchange 2007 SP1
We have an Active Node and Passive Node for the Mailbox role in an SCC Cluster and two additional servers which each hold the Hub Transport and Client Access roles.
My question is, we need to shut the Exchange system down cleanly in order to relocate server rooms. I have never done this before and am unsure as to the correct order to shut the servers down. I have read that it's best to stop the Exchange services and also to pause the nodes and take the cluster group offline. Can anyone advise the correct order of events please

Thank you

Answer : Exchange 2007 SCC Cluster

although I don't have any 'official' documentation, we have a similar setup (except CCR cluster).  The few times we've had to shut down, here's the order we went in (with no problems):

1. shut down passive mailbox node
2. shut down active mailbox node
3. shut down hub/cas with witness share (not sure if this applies to SCC clusters)
4. shut down second hub/cas

We've never manually shutdown any servers first and all our server OS's are 2008.  Oh and we reversed the order when turning everything back on.
