My client bought a vWLC in "small" version but today needs a "large" version as he must deal with more than 200 APs.
We have installed a new VM in version 8.2.170 (his small is in 8.2.151) and had no problem adding the configuration or migrating AP1600 or AP1700.
As for his AP 1852 and 1832, they cannot join the new WLC because of failed/expired certificate.
My colleague told me he had the same problem and had to erase the AP's config before the AP accepted to associate to the new controller.
The problem here is that the client has more than 100 18xx APs and it would be terribly complex to erase the config and modify the primary controller.
Does anyone know a way to force the APs to accept the "large"vWLC's certificate ?
Thank you for your help
