BA created your WT+ booking and sold you a WT+ ticket for that booking. What Asiamiles has done is created a CW (Club World) booking for you and they will take the BA ticket as a form of currency, plus the miles you are spending to "upgrade" it to a business class ticket. Becasue the original WT+ booking was created by BA only they can cancel it. In the mean time, Asiamiles has already booked you a CW seat and has your ticket number so all you have to do is tell BA you want to cancel your WT+ booking but you don't want to refund the ticket (because Asiamiles is taking that ticket and changing it to a CW ticket).
One very important point to note: When using miles to upgrade on BA, no matter if the original tix is flexible or not, once upgraded you can not change the date of travel. At least that was the case 12 months ago when I fell victim to a change in policy. [One the other hand, if you were using miles to upgrade on CX as long as your underlying economy tix is flexible you could change the travel date].
Hope some of this makes sense!
Different CSOs would have different answers regarding to rebooking a BA reward. I did change the travel dates twice successfully in 2007 on a U(W) ticket without paying any surcharges. However they said I have to do it at least 10 days before departure (which I doubt),but anyways rebooking should be ok.
I never called to BA to cancel my W+ booking as the system should update and merge them automatically (from BA ticket (125) to CX reward (160). The only problem of BA upgrade reward is crediting miles. I never get them posted without sending miles claim forms to MPC.
