Upgrading 5508s in High Availabity Mode

[alalli]

Good Day

I was hoping to find out if it is OK to upgrade 5508 Wireless Controllers in High Availabity mode when the normally secondary unit is ACTIVE and the primary unit is in HOT STANDBY mode.

The documentation says to push the upgrade to the ACTIVE unit but does not mention if that must be the primary unit.

Thanks in advance for any input

Yes.  The upgrade can be done on the active controller and the firmware will be automatically pushed down to the secondary controller.

• All download file types (such as image, configuration etc..) are downloaded in the Active WLC first and then pushed automatically to Standby WLC.
• Direct upload and download configuration is not possible in Standby WLC.
