Per Cisco Documentation :

The APs that support this migration are:

· All 1121 access points

· All 1130AG access points

· All 1240AG access points

· All 1250 series access points

For all IOS-based 1200 series modular access point (1200/1220 Cisco IOS Software Upgrade, 1210

and 1230 AP) platforms, it depends on the radio:

¨ if 802.11G, MP21G and MP31G are supported

if 802.11A, RM21A and RM22A are supported

The 1200 series access points can be upgraded with any combination of supported radios: G

only, A only, or both G and A. For an access point that contains dual radios, if one of the two

radios is an LWAPP-supported radio, the upgrade tool still performs the upgrade. The tool

adds a warning message to the detailed log that indicates which radio is unsupported.



· All 1310 AG access points

Cisco C3201 Wireless Mobile Interface Card (WMIC)

Note: The second-generation 802.11a radios contain two part numbers.


Access points must run Cisco IOS Release 12.3(7)JA or later before you can perform the upgrade.

So I am thinking your answer is yes it can be done.

You must use the Cisco Upgrade tool and current IOS must be at 12.3(7)JA or better.

I know the 1230AG can be done as I have done several.

I know the 1200AG cannot be done as I have tried several.

Not sure on the mesh issue - Anyone else know the answer to that.

Hope this helps.....

Sorry...that should read 1220A cannot be done.

I have also done several 1232AG.

Depends on your firmware.
