Sorry if this is repetitive, but I did a search and came up empty.

I've been programming the small Prontos for a long time and just got my first iPronto. Can I simply copy and paste the IR codes from my pcfs into my new icf? If so, are there any limitations? Any potential problems I should be aware of? Am I better off learning the codes anew? It may be more efficient to learn rather than paste, but in a case of contaminated learning, it would be nice to know that I have another option.
