Thanks again for the information, Rose. I tried transferring my saves and tray folder but it wouldn't work properly when trying to replace those files on my new laptop, it wouldn't work right. I think that I'll just keep playing on this computer (old one) and move over the next generations of my current orphan families along with descendants of my current households to a Valley Descendants and a Valley Orphans on the new computer. Once I have enough to get a good start in the new saves, I'll share the remaining households to the gallery so that other Simmers can give them new lives or use them as townies in their games.
I may take a break from Sims 4 today and play Sims 3 and maybe get another legacy going there with either an older Sim from my Sims 3 saves. In the meantime I hope the lot sharing issue gets worked out so that I can save my larger builds like Grace's and Krystal's homes for future use.
Anyways hope you're having a Marvelous Monday!
