Unity Editor Version Backwards Compatibility

Unity Engine
1

Hi folks,

I’m new to Unity, and I’m a bit confused with how projects built with different versions of unity work.
I made this project while learning Unity using version 2019.2.11f1, but when I upgraded to 2019.2.12f1, my old project is suddenly incompatible, and Unity Hub prompts me to download the older version to access the project.
It’s obviously not very practical to recompile every game just to move to a newer version of Unity Editor. So how do you folks deal with this?

you can select new version for the project, from that grayed out drop down button, where it says “select a version”.
(then it will be upgraded to your selected version).

*upgrading to newer version should always work, but downgrading to older version might not work (for example if scene of prefab structure has changed).

Thanks a bunch, that makes much more sense.

I think I need to get a pair of glasses, lol

Always back up your project before opening in a newer version of Unity, as it is generally a one way trip.
