I have CISCO prime 2.0 and CISCO WLC 5508 HA SSO pair.
I would like to upgrade the software code for the WLC HA pair.
Can I do through the CISCO prime ......
As per the link :http://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/7-5/High_Availability_DG.html#pgfId-43571
1. After the WLCs are configured in the HA setup, the Standby WLC cannot be upgraded directly from the TFTP/FTP server.
Prime do the upgrade through FTP server , so will it be ok if we do the upgrade through it, for HA WLC.
Please check this link to upgrade wLC software in HA setup.
Once the Primary WLC complete the upgrade , it will transfer the entire image to the Standby WLC via the Redundant Port.
