Yes, it's possible to migrate the AMT computer list you add through the application. I have downloaded the application and install it and then checked its features. As you can see in the image below, you have the possibility to save the added information. Go to File > Save Intel AMT Computers. The format will be XML and the file you save needs to be transferred using various means to the other computer. Instead of File > Save, use File > Load and browse to file.
