Using the Cluster Administration console, move the Exchange cluster to the next cluster node in the cluster:

       1. Stop the SPAMfighter service that is running on the active cluster node

       2. Open the Exchange Management Shell

       3. Move the Exchange Cluster instance to the next node by using the Move-ClusteredMailboxServer command

       Example:

       Move-ClusteredMailboxServer -Identity:My2k7Cluster -TargetMachine:Ex2k7Node2 -MoveComment:"SPAMfighter installation"

Note: Remember to move the Physical Disk resource in the Cluster Administration at the same time

Note: It is important that you use the Move-ClusterdMailboxServer command to move the cluster - as the Windows Cluster Administration isn't Exchange 2007 cluster aware and may corrupt your mailbox store database(s)
