How to Force LWAPS to Join Secondary Controller

[JASON SIMMONS]

I have an assortment of 1230, 1240, and 1250 AP's converted from autonomous to LWAP mode.  The switch that my primary 5508 WLC is connected to is being retired and I need to move the WLC to a different switch.  What is the best way to force all of the LWAPs to join the secondary5508  WLC prior to taking the primary controller offline?

Go to the primary controller > Wireless > Access Points > Global Configuration

Enter the Secondary WLC details as Back-up Primary Controller IP Address and Back-up Primary Controller name.  Don't save the config.

Go to your secondary controller and do the same process.

When the switch replacement is complete, just revert the changes.

Please don't forget to rate useful posts.  Thanks.

I would build a script for each AP in this format:

config ap primary-base

Then, copy your script, SSH to your primary controller, and paste your script to it. That will push your APs to the secondary controller. After you do your switch migration, run the same script, changing the secondary controller name and IP to the primary.

If you have WCS you could build a lightweight AP template then schedule all the APs to move at once during down time.
