There are, even remote possibility?

Hi folks! There are, even remote, possibility of run in a version before 2.3? I have no much computational resources and just update to last version before beta and with some old projects directed specially for learning according its features. Update again could resolve the troubles but, there's no cost to check first.

Attention: I'm a little far from Unity3D, perhaps, everything simple but, If someone can help me would be nice.

Check the errors:

THIS IS PART OF PROBLEM OF COURSE.

Failed to load 'Assets/Scenes/bootstrapper.unity' because its serialized file version is higher than what this version of Unity supports.

C:/Projects/Unity/FPSSample-master/FPSSample-master/Packages/com.unity.render-pipelines.core/Runtime/Volume/Volume.cs(5,6): error CS0246: The type or namespace name `ExecuteAlways' could not be found. Are you missing an assembly reference?

I'M ONLINE HOLLY S***!
