I'm try to convert some AP's from IOS to Lightweight using the Ugrade Tool version 3.4 but I get an error. I used a sniffer and I saw that the Upgrade Tools start a tftp copy of a "validate.txt" file from the AP to the PC where it is installed. I don't know what is this file and what it should contain. I don't find any document about it. Can some one tell me how create this file and where put it?
Thamk you in advance
