I recently walked into an environment of an Exchange 2007 mailbox cluster that has a node that has been dead for some time. This domain is being migrated away from and the shot callers have no interest in reviving the long-since dead node, or adding another. Since there's no way to convert an Exchange 2007 cluster to a non-cluster, is there any danger in simply evicting the other node and leaving only one node in the cluster? Preferably let me know if you're *certain* of the outcome.
If it matters, the OS is Windows 2008 R1 SP2.
The only reason evicting it even matters is that in preparation for the migration it needs to have it's service pack and rollup done (it's only SP2), and that can't occur with a dead node in the cluster (even with Stop-CMS & Cluster Group /offline).
