Unity project folder library

I have an old computer it gives blue screen everytime i am making a game. So ı have to transfer all of the project folder in google drive for couple months after i buy a new computer.

But project folder is 20 Gb, i don't have that much space. So i want to delete library folder and copy it to google drive, i know unity reinstalls library but does it make a problem when it's in a diffrent computer?

And sorry for poor English.
