Unity how to copy 1 scene from one project to another

So at first what i am trying to do is to copy paste the scene but that will not work as all the dependency and object reference is gone,

what you need to do is

right click the scene you want to copy then "export package" then tick the "include all dependancy" then once you are done give it a name such as "myexportpackage"

open your other project

under edit -> import package, then choose your package to import, it work fine
