HA WLC Pair

[helpdesk helpdesk]

We purchased a pair of  WLCs with a layer 2 link between the 2. As it has turned out this link won't be

available anytime soon. The problem we have is the primary site has the HA WLC installed with no

intrinsic AP = 0 support, and the WLC with the 500 licenses is in the secondary. Is there any magic

that can be worked to swap the license over remotely so we don't have to physically swap the hardware

over ?

No, in fact I'm about to do a blog post on this subject ..

Here is a recent TAC case I opened ..

Regarding your questions:

Problem Details: I have a question specific to the 5508 and WISM HA SKU part number.

AIR-CT5508-HA-K9  - If purchased can it be converted back to a licensable WLC. In other words, can i make this a regular WLC.

Can I convert an HA SKU to a primary by adding licenses?

No. This migration is not supported. The exception is if someone converted a controller with licenses to HA in the first place and now intends to revert back. The WLC retain the licenses.

If I have a licensable WLC today. What minimum license requirement is needed to turn a WLC into HA ?

The controller needs to have at least 50 access point licenses in order to be able to convert the controller to the standby controller for the wireless LAN.

For this case to convert a  WLC standalone to a WLC in HA, anyone know what is the process that has to be done?

thanks

No, till this point of time this is not feasible that we can swap the license over remotely so we don't have to physically swap the hardware over.

This migration is not possible.
