Problem with dependencies

Hi,i have a little problem,i have an older project of mine,from when i was in highschool with some friends,and i wanted some gameobjects with all the components and scripts to use them in a newer project,i still use the unity 2017.4.39f1 i made a prefab from a gameobject and when i go to assets>Export package and i selected only that prefab but with dependencies checked but when i import that package in the other project(default project with nothing in it) i only some components like colliers and transform but not any script or mesh renderer or filter and when i open the package in the new project it is empty without any scripts or meshes or audio. I checked online on unity forums and read some articles and seems to be a problem with dependencies when i create that package,it doesen't include any dependencies even though i checked it,what do you guys recomend to do?upgrade the project to 2019 or 2020,is there some work around to this probably to manualy transfer the scripts and meshes and other stuff but it will be still connected togheter?
