The bootloader is actually part of the main image and will automatically be upgraded if needed. A lot of people refer to the ER image as the bootloader which is a seperate file. If you are upgrading the main image and the ER image you will want to load each image seperately and reboot between each load.
As far as failover, if its just for a controller reboot you could put the controllers in different mobility groups. They shouldn't failover then. Otherwise you would need to look at an ACL or AP authorization to keep them AP's from joining a different controller.
Specific to the AP failover. Why dont you deploy AP FALLBACK? When a controller falls offline for
any reason the APs join other controllers. HOWEVER when the controller comes online they will fallback to the controllers
you want with NO intervention from you.
When an access point’s primary controller comes back online, the access point disassociates from the backup controller and reconnects to its primary controller. The access point falls back to its primary controller and not to any secondary controller for which it is configured. For example, if an access point is configured with primary, secondary, and tertiary controllers, it fails over to the tertiary controller when the primary and secondary controllers become unresponsive and waits for the primary controller to come back online so that it can fall back to the primary controller. The access point does not fall back from the tertiary controller to the secondary controller if the secondary controller comes back online; it stays connected to the tertiary controller until the primary controller comes back up.
