Clustering (2 nodes) has caused me more problems than it's fixed in the last months. So now I want to rip it out - just go with a single Exchange server. Can someone give some advice on the best way to move to single server after having been clustered? We're in a multi blade Cisco UCS VMWare environment. So at the OS/machine level there is redundancy and capacity out the yin yang. I know we have some considerations such as the Offline Address Book which will need to be approached differently in non-clustered mode. Thoughts, experiences, reference URLs all appreciated.
