Minimally Disruptive Migration Procedure

When migrating Windows Server 2012 clusters, maintenance mode must be set on the cluster
disks to clear SCSI reservations on these disks. Because the quorum disk cannot be set in
maintenance mode, it should be set offline to clear the SCSI reservations. Then, all of the cluster
nodes should be shut down.
When migrating all other Windows clusters (refer to the support matrix for the supported releases),
simply shut down all of the cluster nodes. Doing this releases all of the SCSI reservations on the
cluster disks, including quorum disks.
