They've said the upgrade won't work unless all of your flight sectors are in the same class. Mine is PEY from YVR to HKG, and then Y(B fare) from HKG to KUL
Maybe next time you would consider booking J for the intra-asia sector to get around this issue. I booked something similar ages ago ex-LAX when CX had special double (or triple?) miles to promote PEY when it was first introduced so instead of J, it made more sense to book PEY and use AM to upgrade (as I was able to get it confirmed when booking). Back then, fare difference (for J instead of Y for SE Asia destinations) was USD 50 one-way because CX pairs long-haul PEY with B (or H) bucket. I suspect you still have to call because CX website probably still automatically pair PEY with Y instead of J.
