Hi Jason,
I totally agree with Cody Green. Your best best is going to be an SCF File for upgrades of different hardware types (just make sure that when using this method that the 6400 and 3900 are on the exact same OS Version and HF). I have used that method successfully with upgrades from 6400's to 8950's, but the same methodology will hold true when going to 3900's (which are pretty much the closest your are going to get to the 6400's that you have in ability).
Arie also makes a good point. With the ever increasing features and abilities that are being added you may eventually reach limitations on what you can do and need a hardware upgrade (depending upon how many advanced features you are using).
