You can migrate cluster resources to different servers in your cluster without waiting for a failure to occur. You might want to migrate resources to lessen the load on a specific server, to free up a server so it can be brought down for scheduled maintenance, or to increase the performance of the resource or application by putting it on a faster machine.
Migrating resources lets you balance the load and evenly distribute applications among the servers in your cluster.
