Installing the Sims 2 on Windows 10?

Hiya - I made an account because I have some questions along a similar line, but I can't make a new topic, because, you know, new.

So I have Sims 2 and a bunch of expansions installed on a Windows 10 laptop right now - all my data was on an XP before and I already moved it and did the thing in the video to make it work. I'm now getting a new Windows 10 laptop, though. Will I have to do it again when I move all the files over?

Also, when it comes to reinstalling the games, do I have to use the same discs with the same serial codes for my saves to load up as they used to? I still have the expansion packs but I gave away my old 4 disc base game. If I buy another 4 disc version and install that alongside the expansion packs, will I be able to run my data? Or are the serial codes linked to the data? If anyone knows, that would be great.

Would just get the base game and try to get the UC, but that's about 12 years worth of neighbourhood building I have on there, haha.
