I have some Krisflyer miles that are going to expire soon. I see from SingaporeAir website that I can transfer them to many partner frequent flyer programmes, including Aeroplan.

My questions are:
1) Let's say I have 40k Krisflyer miles, would they become 40K Aeroplan miles
2) Would they expire at the same time of my current Krisflyer miles or would they get extended?
