Newer versions do not switch interfaces that transparently, either, but at least you get an option to choose an alternate output when it errors, which may not be the case in 6.2.1 - I don't recall.
I would try something like this:
1. Route all the tracks in the project to a Master bus (via aux buses as necessary), so that only the Master needs to be reassigned.
2. Set the Output of the Master bus to None before saving the project, so you don't get an error when opening it.
3. Set the Master bus output to whichever interface is available after opening the project and you should be ready to go.
Changing external MIDI port routing is a whole other ball o' wax. It has gotten somewhat better, but is still wonky.
