AIR-AP-3802I-B-K9 Lightweight to Mobility Express Firmware conversion

[gbwiersum]

I'm trying to convert my 3802I from capwap to Mobility-Express. The problem is, Mobility-express isn't listed as a valid ap-type in the installed firmware.

So when I try:

ap-type mobility-express tftp://192.168.1.3/D:\TFTP\AIR-AP3800-K9-ME-8-10-196-0.tar

obviously:

Is there a good workaround? Have I done something completely wrong?

Here's the guide I'm following

Thanks

  - You may need to do this via the console ; review this documentation too :

I am using the console.

When I try to get-request the file from my server, the command fails because ap-type only accepts "capwap" and "workgroup-bridge" as valid arguments.

 - Then it looks to me that it is running an image type that is not capable of doing this,

The AP must be running a very old version of software (before Mobility Express was supported).
Install the latest (AireOS compatible) CAPWAP image *before* trying to convert to Mobility Express.  It's best to do that anyway for a successful conversion.
