xSky_watcher I was wondering whether or not it is possible to upgrade my 32GB SD card that is currently in use for my AsiAirPro to a 128 GB SD card.
Tim,
You can use a larger microSD card, but unless you know your way about Raspbian, there is no way for you to expand the partitions to anything larger than what is already there. I.e., if you start with 20 GB of free storage space, you will still only have 20 GB of free storage even if you use a 128 GB microSD card.
In any case, it is better (for the sake of the microSD connector in the ASIAIR) to extract and insert the microSD card as little as possible, and use USB storage instead (either USB flash sticks, or USB solid state drives), if you are looking for removable media.
