Ah, it seems that Twallan has yet to transfer the full information onto his wiki. Vodka puts me in a good enough mood to tell you, though. Porter has the automatic function of looking for duplicate sims (based on name and favourites), and allows you to replace them. This way, you can have many groups of people from one neighbourhood in different "packs" (with duplicates) moved one at a time. The safest method to retain all the information is probably to just pack one family and all of their relationships at a time. If Porter maintains the relationships with other sims not in a pack, it might even be simpler. Just unpack your whole town once and then a second time because it will (hopefully) recognize all the sims as being there, and connect them. But basically, Twallan's answer was redundancy.
Then again, vodka and late nights don't exactly make me think straight.

Thanks for your help, I appreciate it! Now my whole population maintains its full relationship between each other
After what you wrote I decided to try again and pack the whole neighbourhood at once. So I used NRAAS master controller to reset the whole world and then packed all the sims at once.
I then unpacked it into the world that I moved the population 1/3 at a time into (Also where 1/3 of the relationships of the town were lost between each other) and then all when all the unpacking finished all my relationships were kept and there were no duplicate sims!
But the first time I tried to unpack the whole sim population into a new town it crashed though, but I only tried once... might have been unlucky that time.
I also found this on the NRAAS site "What sort of issues should I be aware of ? 3.Do not attempt to export your entire town in a single family. The game will run out of memory attempting to create the file and either hang indefinitely or crash to the desktop." I think that's what he was referring to at the time (I wasn't sure I just assumed, but now I understand its not), so that's why after I decided to move the population of the town at 1/3s at a time.
