I have a tough decision to make. I have an Exchange 2000 cluster built by some consultants. It sucks. I want to rebuild it with out buying new hardware and not noticed by the users. What is the best way. I've thought of unstalling cluster services rebuilding one, moving the mailboxes then rebuilding the other and then re-cluster. or evict one node. Rebuild it. Rejoin the cluster, evict the other node, then rebuild it. Any ideas?
