Sorry, I had forgotten. By all means run the Batbox nuke trash memories, but avoid nuking the corrupt ones, at least as far as any default sims are concerned - a lot of them do have corrupt memories, but you need to correct them in SimPE unless you want, for example, Don Lothario to have no memories of his family history. (Of course, if you are moving Don without his ancestors, then you should nuke those memories) If your CAS or BIG sims have corrupt memories, again try correcting them in SimPE - unfortunately, since the BatBox doesn't list the corrupt memories it finds before nuking them, you would need to check each and every memory to find those which refer to the wrong subject, or no subject at all, or refer to an Unknown. It can be a long and wearisome job, but if you want to continue playing families where some degree of corruption has set in, it just has to be done. Often, the problem can be traced back to a time when the player didn't realise the dangers of in-game deletion of sims, but whether this is so in your case, of course, I don't know - probably depends on how many years you have been playing this hood.
Basically, if you've moved (or, to be exact, copied) a single sim from one hood to another without problems, then there should be no reason why you can't move a large, extended family. Just, whatever work you had to do with the one sim is multiplied.
One thing I would suggest is to remove custom makeup and clothing before you move the family, keeping a note of what particular custom clothing you want your sims to have when you start to play them again, and then pull the entire make-up and clothing folders from your Downloads before you package them up - the amount of stuff that gets into the package from both your resident sims and all their acquaintances can be enormous.
One further thought, if you didn't get a lot segment, then use a small, unfurnished house, not an empty lot.
