Migrating AP's from a 4400 to a 2504.

[JohnNetEng]

I have a several Cisco 1252's connected to a 4400 running 7.0.235.0 in local

admin mode.

I need to migrate them to a 2504 running 7.2.110.0. Aside from the appropriate

WLAN's and AP groups..etc, do I need to upload individual AP firmware for these 1252's

to the new controller itself for support, or can I just point these to the 2504?

You can just point 1252s to your 2504 under AP High Availablilty section by configuring primary controller as your 2504.

No need to upload AP firmware individually. WLC(2504)will push the latest image to your APs once joined

adding to rasika ...

Make sure the WLC's are on the same mobility group and the mobility group is up.

The easiest way to do this is to just put both controllers into the same mobility group then define the 2nd WLC(2504)as the primary controller for the AP's.

Wireless>AP Details and the change the primary and secondary WLC name and IP.

If you want to move the AP to associate from one WLC to another, use the command on the WLC where the AP's are currently associated to:

config ap primary-base

I'm with Scott.

If you plan to MIGRATE from one WLC to another (and no longer use the older 4400) then you do not need to put the WLC in the same mobility group.

I recently migrated from a 4400 to a 5508.  I uploaded the configuration of the 4400 into the 5508 and worked very well.  No need to edit anything because the IP address both are the same.  Once I downloaded the config off the 4400 it was powered off.

Hi Sandeep,

This to work you do not want to have the same mobility group on your controller. Below from the 7.4 config guide

A single controller at a centralized location can act as a backup for access points when they lose connectivity with the primary controller in the local region. Centralized and regional controllers do not need to be in the same mobility group. You can specify a primary, secondary, and tertiary controller for specific access points in your network. Using the controller GUI or CLI, you can specify the IP addresses of the backup controllers, which allows the access points to fail over to controllers outside of the mobility group.

Thanks for correcting me, you guys are champ.

You actually don't need the WLC in the same mobility group. I though so to until I tested it out. You just need to change the high availability on the access point.

I actually had to migrate 200+ AP's this way not too long ago.
