Change of address and N 400 application of naturalization?

Ok this the situation: My N400 for naturalization is in its last stages, im waiting on my interview, which could be any time. My locaton is orlando FL, I have to move to Miami FL to attend school in 3 weeks, I will be leaving my current appartment and will be renting one in Miami. What is the best way to avoid complications, should I change to my friend's adreess which is here in orlando and make miami as temporary or mailing address??? Will it work? Because I think if i change address to miami it will delay the preocess as they will have to send my file to miami..

If yes then also should i change address on my driver's lisence to my friend's, or can i change it to miami.
