controller, whether the network has a single master controller or a cluster of master controllers, and whether or
not the controller has a backup.
The following sections describe the steps to replace an existing controller. To add a new local controller to a network,
or to permanently remove a local controller without replacing it, see Viewing and Managing the Master or Local

Use the procedures in this section to replace a master or local controller in a network environment with a single
master controller.
Replacing a Local Controller
