I am currently working on unity at my school. The only problem is that the computers there have unity 2018 3.10f and the unity I have at home is 2019.3 I know an easy solution would be to use the same version as the school computers except I can’t stand unity 2018, it looks so ugly. The unity at my school also cannot be updated either. Whenever I make a project at home and try to run it on the school computer I get a bunch of errors.
How do I transfer my projects between different versions of unity without getting errors?
There is no support in Unity for version downgrades.
Features and file structures as saved in your project can change between versions, and Unity includes scripts to convert old projects to the current version. But because Unity has thus far failed to perfect their time machine, they are unable to write similar scripts for converting projects made in versions of Unity which do not yet exist. So Unity 2018 cannot safely use projects created in Unity 2019.3.
If you do perfect your own time machine though, please let Unity know.
