Help!!! About the change of version

Unity Engine
1

I changed the version from unity 2018.3.9 to 20181.6,all the prefab missed. how can I do to solve this problem?

I guess the second one is 2018.1.6. Here are the things:

  • General discussion is not a support forum, please honor the forum rules
  • Downgrading (opening the project lower version of Unity than before) is not supported at all, never were
  • Unity introduced the new prefab system in 2018.3, it is a one-way street, you cannot convert the new prefabs to the old ones
  • You need to go back to the last saved version in your version control system before you migrated into 2018.3
  • if you started your project in 2018.3 you simply cannot downgrade, you can open up your project and you can try to fix the problems and recreate the prefabs, but you probably would be better off if you simply recreate your project
