Moving from old to new save - worth it?

I started one of my generational saves around December 2019 when my parents gifted me Discover University for Christmas, and I've been playing with it ever since. Lately, I've been thinking about the possibility of moving my whole gameplay shebang from my old save to a new one. As in: creating a fresh save in 2026 now, saving all the houses in the old save and replacing them in this new save, saving my still living families to the Library and dropping them in the worlds. It would be tedious and definitely take a lot of fiddling with settings but I'm thinking it might be worth it. The question is - is it, though?

Pros of moving: no bugs that have been fixed by now but only on new saves (AKA post-fix) and there's a lot of them, updated/upgraded gameplay mechanics and townies etc., a fresh and more stable save file (mine's gonna be 7yo soon), I've mainly focused on one-two generations at a time so there's not much worry about NPCs and background characters.

Cons of moving: any gameplay/world-changing progress I've made (Strangerville infection, Sulani clean-up, Evergreen Harbor eco status...es just to name a few), keeping track of the sims' relationships and their family tree (my biggest concern - will two separate households of the same family know each other after being placed in a new world?), new bugs.

Some pros are better than other ones, some cons are definitely bigger than other ones... So, that begs the question - is it worth considering? Would all that work help or just make me more angry at the game? Has anyone here tackled this issue before? How was your experience? I play on PC and I almost never use mods so things like moving CC or anything are not a problem I worry about. Entertaining all answers, it's not a time-sensitive problem. I wasn't sure if this should go here or into General Discussion but here goes!! :)
