I went through this last night here is the notes I wrote as i went through it I hope this helps I welcome feedback on the procedure I wrote as I will try to make more formal documentation from it for you all to use on CCO
The below is not official documentation but simply my notes from when I had to work this out myself last night. I have tested it and it works.
This is the instructions to convert the AP and keep the current configuration.
Remember this util only works for AP1200's it will NOT convert AP350's
If you want to default the config to factory and upgrade then simply install the helper image as you would upgrade firmware normally.
Before you start make sure the AP has SNMP set up correctly and you know the username (community string) and password. Also upgrade to the latest VxWorks firmware 12.02T1 It will not work with 12.01T !!! But does with 11.54
Make sure the SNMP username has rights to all including firmware.
1. Download Aironet-AP-Cisco-IOS-Conversion-Tool-v1.exe and AP1200-Cisco-IOS-Upgrade-Image-v1.img Yes you need both even though the description doest look like you do.
Here is the link to this software

2. Install the conversion tool
3. Add task
4. Under source configuration select "from" as device in device information put in the IP address of the AP and admin name which will be the SNMP username (community string)
5. Under Target configuration select "to" as device, helper image will be the location of AP1200-Cisco-IOS-Upgrade-Image-v1.img on your PC's hard disk, enable password will be the password you set for the SNMP user, IP address of the device (same as in step 4) admin name will be the SNMP username (same as step 4)
6. Interface for communicating with target access point should be filled in by default but if not it is your PC's IP address.
7. click next
8. select yes to the warning that this is a one way process
9. Get security config
10. When it has downloaded the security config click on each line of config it has downloaded and set the password to what was configured on the AP for these fields
11. Click finish
12. Highlight the task you have just selected
13. Click start task, it is all done for you from here on, but it encounters an error there is a log to give you more information on what went wrong.
