How can i change regulatory domain C to A of access point

Recently my office got an access point - (AIR-CAP2602E-C-K9)  which is not synchronizing with controller (AIR-CT2504-5-K9 )as it is in domain A , all other AP also in domain A. Now can i change the domain of access point or what is the possible solution to add new AP with controller ? is it possible to run both domain (A, C)  at the same time with one controller ?

Unfortunately you can not

Unfortunately you can not change the domain on the AP. 

They are built that way from the factory. 

We purchased some in the wrong region as well and are unable to use the 5GhZ band.


You will have to enable that region on your controller to accept capwap join requests. Yes you can run both. 

Migrating Access Points from

Migrating Access Points from the -J Regulatory Domain to the -U Regulatory Domain

The Japanese government has changed its 5-GHz radio spectrum regulations. These regulations allow a field upgrade of 802.11a 5-GHz radios. Japan allows three frequency sets:

J52 = 34 (5170 MHz), 38 (5190 MHz), 42 (5210 MHz), 46 (5230 MHz)

W52 = 36 (5180 MHz), 40 (5200 MHz), 44 (5220 MHz), 48 (5240 MHz)

W53 = 52 (5260 MHz), 56 (5280 MHz), 60 (5300 MHz), 64 (5320 MHz)

Cisco has organized these frequency sets into the following regulatory domains:

-J regulatory domain = J52

-P regulatory domain = W52 + W53

-U regulatory domain = W52

Regulatory domains are used by Cisco to organize the legal frequencies of the world into logical groups. For example, most of the European countries are included in the -E regulatory domain. Cisco access points are configured for a specific regulatory domain at the factory and, with the exception of this migration process, never change. The regulatory domain is assigned per radio, so an access point's 802.11a and 802.11b/g radios may be assigned to different domains.
