So I have FSX Deluxe, is it possible to just upgrade to Acceleration instead of getting rid of FSX deluxe and buying Acceleration?

you have to buy Acceleration in order to get Acceleration.
Acceleration is just an expansion pack, not a different game.

Final answer is yes, you can upgrade, because Acceleration installs on top of FSX Deluxe.
BUT it is usually recommended to install Acceleration on top of a very fresh, addon-free FSX, just for stability issues.
