Inspiron 15Z network (wifi) card replacement

I was disappointed to find out my wifi card in my 15Z was not dual band.   I am thinking about replacing it so I can use tehe 5ghz band.   I am thinking about replacing it with a Intel® Centrino® Advanced-N 6235.   Does anyone know if this is swappable with the Intel® Centrino® Wireless-N 2230 that is already installed?  Anyone know how difficult it is to swap out?

Thanks
