"update from nios II/f to nios II/e" ?!!  

/f means "fast",  

/e means "economic" wich is offerd at no cost. 

 

See : http://www.altera.com/devices/processor/nios2/ni2-index.html

You will not see much of a difference if you are running simple programs like "hello world", LED blinking and stuff. 

Before you port, you may need to understand what your application is trying to do and what it needs. This is because Nios II/e only support a subset of Nios II/f features. Nios II/e does not support hardware multiply/divide (may result in poor multiply/divide performance), MMU (not able to run linux) and etc.
